-name: shadcn
-description: Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".

-# shadcn/ui
-
-A framework for building ui, components and design systems. Components are added as source code to the user's project via the CLI.
-
-> **IMPORTANT:** Run all CLI commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest` — based on the project's `packageManager`. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
-
-## Current Project Context
-
-```json
-!`npx shadcn@latest info --json 2>/dev/null || echo '{"error": "No shadcn project found. Run shadcn init first."}'`
-```
-
-The JSON above contains the project config and installed components. Use `npx shadcn@latest docs <component>` to get documentation and example URLs for any component.
-
-## Principles
-
-1. **Use existing components first.** Use `npx shadcn@latest search` to check registries before writing custom UI. Check community registries too.
-2. **Compose, don't reinvent.** Settings page = Tabs + Card + form controls. Dashboard = Sidebar + Card + Chart + Table.
-3. **Use built-in variants before custom styles.** `variant="outline"`, `size="sm"`, etc.
-4. **Use semantic colors.** `bg-primary`, `text-muted-foreground` — never raw values like `bg-blue-500`.
-
-## Critical Rules
-
-These rules are **always enforced**. Each links to a file with Incorrect/Correct code pairs.
-
-### Styling & Tailwind → [styling.md](./rules/styling.md)
-
-- **`className` for layout, not styling.** Never override component colors or typography.
-- **No `space-x-*` or `space-y-*`.** Use `flex` with `gap-*`. For vertical stacks, `flex flex-col gap-*`.
-- **Use `size-*` when width and height are equal.** `size-10` not `w-10 h-10`.
-- **Use `truncate` shorthand.** Not `overflow-hidden text-ellipsis whitespace-nowrap`.
-- **No manual `dark:` color overrides.** Use semantic tokens (`bg-background`, `text-muted-foreground`).
-- **Use `cn()` for conditional classes.** Don't write manual template literal ternaries.
-- **No manual `z-index` on overlay components.** Dialog, Sheet, Popover, etc. handle their own stacking.
-
-### Forms & Inputs → [forms.md](./rules/forms.md)
-
-- **Forms use `FieldGroup` + `Field`.** Never use raw `div` with `space-y-*` or `grid gap-*` for form layout.
-- **`InputGroup` uses `InputGroupInput`/`InputGroupTextarea`.** Never raw `Input`/`Textarea` inside `InputGroup`.
-- **Buttons inside inputs use `InputGroup` + `InputGroupAddon`.**
-- **Option sets (2–7 choices) use `ToggleGroup`.** Don't loop `Button` with manual active state.
-- **`FieldSet` + `FieldLegend` for grouping related checkboxes/radios.** Don't use a `div` with a heading.
-- **Field validation uses `data-invalid` + `aria-invalid`.** `data-invalid` on `Field`, `aria-invalid` on the control. For disabled: `data-disabled` on `Field`, `disabled` on the control.
-
-### Component Structure → [composition.md](./rules/composition.md)
-
-- **Items always inside their Group.** `SelectItem` → `SelectGroup`. `DropdownMenuItem` → `DropdownMenuGroup`. `CommandItem` → `CommandGroup`.
-- **Use `asChild` (radix) or `render` (base) for custom triggers.** Check `base` field from `npx shadcn@latest info`. → [base-vs-radix.md](./rules/base-vs-radix.md)
-- **Dialog, Sheet, and Drawer always need a Title.** `DialogTitle`, `SheetTitle`, `DrawerTitle` required for accessibility. Use `className="sr-only"` if visually hidden.
-- **Use full Card composition.** `CardHeader`/`CardTitle`/`CardDescription`/`CardContent`/`CardFooter`. Don't dump everything in `CardContent`.
-- **Button has no `isPending`/`isLoading`.** Compose with `Spinner` + `data-icon` + `disabled`.
-- **`TabsTrigger` must be inside `TabsList`.** Never render triggers directly in `Tabs`.
-- **`Avatar` always needs `AvatarFallback`.** For when the image fails to load.
-
-### Use Components, Not Custom Markup → [composition.md](./rules/composition.md)
-
-- **Use existing components before custom markup.** Check if a component exists before writing a styled `div`.
-- **Callouts use `Alert`.** Don't build custom styled divs.
-- **Empty states use `Empty`.** Don't build custom empty state markup.
-- **Toast via `sonner`.** Use `toast()` from `sonner`.
-- **Use `Separator`** instead of `<hr>` or `<div className="border-t">`.
-- **Use `Skeleton`** for loading placeholders. No custom `animate-pulse` divs.
-- **Use `Badge`** instead of custom styled spans.
-
-### Icons → [icons.md](./rules/icons.md)
-
-- **Icons in `Button` use `data-icon`.** `data-icon="inline-start"` or `data-icon="inline-end"` on the icon.
-- **No sizing classes on icons inside components.** Components handle icon sizing via CSS. No `size-4` or `w-4 h-4`.
-- **Pass icons as objects, not string keys.** `icon={CheckIcon}`, not a string lookup.
-
-### CLI
-
-- **Never decode or fetch preset codes manually.** Pass them directly to `npx shadcn@latest init --preset <code>`.
-
-## Key Patterns
-
-These are the most common patterns that differentiate correct shadcn/ui code. For edge cases, see the linked rule files above.
-
-```tsx
-// Form layout: FieldGroup + Field, not div + Label.
-<FieldGroup>
-  <Field>
-    <FieldLabel htmlFor="email">Email</FieldLabel>
-    <Input id="email" />
-  </Field>
-</FieldGroup>
-
-// Validation: data-invalid on Field, aria-invalid on the control.
-<Field data-invalid>
-  <FieldLabel>Email</FieldLabel>
-  <Input aria-invalid />
-  <FieldDescription>Invalid email.</FieldDescription>
-</Field>
-
-// Icons in buttons: data-icon, no sizing classes.
-<Button>
-  <SearchIcon data-icon="inline-start" />
-  Search
-</Button>
-
-// Spacing: gap-*, not space-y-*.
-<div className="flex flex-col gap-4">  // correct
-<div className="space-y-4">           // wrong
-
-// Equal dimensions: size-*, not w-* h-*.
-<Avatar className="size-10">   // correct
-<Avatar className="w-10 h-10"> // wrong
-
-// Status colors: Badge variants or semantic tokens, not raw colors.
-<Badge variant="secondary">+20.1%</Badge>    // correct
-<span className="text-emerald-600">+20.1%</span> // wrong
-```

-## Key Fields
-
-The injected project context contains these key fields:
-
-- **`aliases`** → use the actual alias prefix for imports (e.g. `@/`, `~/`), never hardcode.
-- **`isRSC`** → when `true`, components using `useState`, `useEffect`, event handlers, or browser APIs need `"use client"` at the top of the file. Always reference this field when advising on the directive.
-- **`tailwindVersion`** → `"v4"` uses `@theme inline` blocks; `"v3"` uses `tailwind.config.js`.
-- **`tailwindCssFile`** → the global CSS file where custom CSS variables are defined. Always edit this file, never create a new one.
-- **`style`** → component visual treatment (e.g. `nova`, `vega`).
-- **`base`** → primitive library (`radix` or `base`). Affects component APIs and available props.
-- **`iconLibrary`** → determines icon imports. Use `lucide-react` for `lucide`, `@tabler/icons-react` for `tabler`, etc. Never assume `lucide-react`.
-- **`resolvedPaths`** → exact file-system destinations for components, utils, hooks, etc.
-- **`framework`** → routing and file conventions (e.g. Next.js App Router vs Vite SPA).
-- **`packageManager`** → use this for any non-shadcn dependency installs (e.g. `pnpm add date-fns` vs `npm install date-fns`).
-
-See [cli.md — `info` command](./cli.md) for the full field reference.
-
-## Component Docs, Examples, and Usage
-
-Run `npx shadcn@latest docs <component>` to get the URLs for a component's documentation, examples, and API reference. Fetch these URLs to get the actual content.
-
-```bash
-npx shadcn@latest docs button dialog select
-```
-
-**When creating, fixing, debugging, or using a component, always run `npx shadcn@latest docs` and fetch the URLs first.** This ensures you're working with the correct API and usage patterns rather than guessing.
-
-## Workflow
-
-1. **Get project context** — already injected above. Run `npx shadcn@latest info` again if you need to refresh.
-2. **Check installed components first** — before running `add`, always check the `components` list from project context or list the `resolvedPaths.ui` directory. Don't import components that haven't been added, and don't re-add ones already installed.
-3. **Find components** — `npx shadcn@latest search`.
-4. **Get docs and examples** — run `npx shadcn@latest docs <component>` to get URLs, then fetch them. Use `npx shadcn@latest view` to browse registry items you haven't installed. To preview changes to installed components, use `npx shadcn@latest add --diff`.
-5. **Install or update** — `npx shadcn@latest add`. When updating existing components, use `--dry-run` and `--diff` to preview changes first (see [Updating Components](#updating-components) below).
-6. **Fix imports in third-party components** — After adding components from community registries (e.g. `@bundui`, `@magicui`), check the added non-UI files for hardcoded import paths like `@/components/ui/...`. These won't match the project's actual aliases. Use `npx shadcn@latest info` to get the correct `ui` alias (e.g. `@workspace/ui/components`) and rewrite the imports accordingly. The CLI rewrites imports for its own UI files, but third-party registry components may use default paths that don't match the project.
-7. **Review added components** — After adding a component or block from any registry, **always read the added files and verify they are correct**. Check for missing sub-components (e.g. `SelectItem` without `SelectGroup`), missing imports, incorrect composition, or violations of the [Critical Rules](#critical-rules). Also replace any icon imports with the project's `iconLibrary` from the project context (e.g. if the registry item uses `lucide-react` but the project uses `hugeicons`, swap the imports and icon names accordingly). Fix all issues before moving on.
-8. **Registry must be explicit** — When the user asks to add a block or component, **do not guess the registry**. If no registry is specified (e.g. user says "add a login block" without specifying `@shadcn`, `@tailark`, etc.), ask which registry to use. Never default to a registry on behalf of the user.
-9. **Switching presets** — Ask the user first: **reinstall**, **merge**, or **skip**?
-   - **Reinstall**: `npx shadcn@latest init --preset <code> --force --reinstall`. Overwrites all components.
-   - **Merge**: `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to list installed components, then for each installed component use `--dry-run` and `--diff` to [smart merge](#updating-components) it individually.
-   - **Skip**: `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS, leaves components as-is.
-
-## Updating Components
-
-When the user asks to update a component from upstream while keeping their local changes, use `--dry-run` and `--diff` to intelligently merge. **NEVER fetch raw files from GitHub manually — always use the CLI.**
-
-1. Run `npx shadcn@latest add <component> --dry-run` to see all files that would be affected.
-2. For each file, run `npx shadcn@latest add <component> --diff <file>` to see what changed upstream vs local.
-3. Decide per file based on the diff:
-   - No local changes → safe to overwrite.
-   - Has local changes → read the local file, analyze the diff, and apply upstream updates while preserving local modifications.
-   - User says "just update everything" → use `--overwrite`, but confirm first.
-4. **Never use `--overwrite` without the user's explicit approval.**

-
-**Named presets:** `base-nova`, `radix-nova`
-**Templates:** `next`, `vite`, `start`, `react-router`, `astro` (all support `--monorepo`) and `laravel` (not supported for monorepo)
-**Preset codes:** Base62 strings starting with `a` (e.g. `a2r6bw`), from [ui.shadcn.com](https://ui.shadcn.com).

-# shadcn CLI Reference
-
-Configuration is read from `components.json`.
-
-> **IMPORTANT:** Always run commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest`. Check `packageManager` from project context to choose the right one. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
-
-> **IMPORTANT:** Only use the flags documented below. Do not invent or guess flags — if a flag isn't listed here, it doesn't exist. The CLI auto-detects the package manager from the project's lockfile; there is no `--package-manager` flag.

-| `--dry-run`     |       | Preview all changes without writing files                                                                            | `false` |
-| `--diff [path]` |       | Show diffs. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`)         | —       |
-| `--view [path]` |       | Show file contents. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`) | —       |
-
-#### Dry-Run Mode
-
-Use `--dry-run` to preview what `add` would do without writing any files. `--diff` and `--view` both imply `--dry-run`.
-
-```bash
-# Preview all changes.
-npx shadcn@latest add button --dry-run
-
-# Show diffs for all files (top 5).
-npx shadcn@latest add button --diff
-
-# Show the diff for a specific file.
-npx shadcn@latest add button --diff button.tsx
-
-# Show contents for all files (top 5).
-npx shadcn@latest add button --view
-
-# Show the full content of a specific file.
-npx shadcn@latest add button --view button.tsx
-
-# Works with URLs too.
-npx shadcn@latest add https://api.npoint.io/abc123 --dry-run
-
-# CSS diffs.
-npx shadcn@latest add button --diff globals.css
-```
-
-**When to use dry-run:**
-
-- When the user asks "what files will this add?" or "what will this change?" — use `--dry-run`.
-- Before overwriting existing components — use `--diff` to preview the changes first.
-- When the user wants to inspect component source code without installing — use `--view`.
-- When checking what CSS changes would be made to `globals.css` — use `--diff globals.css`.
-- When the user asks to review or audit third-party registry code before installing — use `--view` to inspect the source.
-
-> **`npx shadcn@latest add --dry-run` vs `npx shadcn@latest view`:** Prefer `npx shadcn@latest add --dry-run/--diff/--view` over `npx shadcn@latest view` when the user wants to preview changes to their project. `npx shadcn@latest view` only shows raw registry metadata. `npx shadcn@latest add --dry-run` shows exactly what would happen in the user's project: resolved file paths, diffs against existing files, and CSS updates. Use `npx shadcn@latest view` only when the user wants to browse registry info without a project context.

-
-### `search` — Search registries
-
-```bash
-npx shadcn@latest search <registries...> [options]
-```
-
-Fuzzy search across registries. Also aliased as `npx shadcn@latest list`. Without `-q`, lists all items.
-
-| Flag                | Short | Description            | Default |
-| ------------------- | ----- | ---------------------- | ------- |
-| `--query <query>`   | `-q`  | Search query           | —       |
-| `--limit <number>`  | `-l`  | Max items per registry | `100`   |
-| `--offset <number>` | `-o`  | Items to skip          | `0`     |
-| `--cwd <cwd>`       | `-c`  | Working directory      | current |
-
-### `view` — View item details
-
-```bash
-npx shadcn@latest view <items...> [options]
-```
-
-Displays item info including file contents. Example: `npx shadcn@latest view @shadcn/button`.
-
-### `docs` — Get component documentation URLs
-
-```bash
-npx shadcn@latest docs <components...> [options]
-```
-
-Outputs resolved URLs for component documentation, examples, and API references. Accepts one or more component names. Fetch the URLs to get the actual content.
-
-Example output for `npx shadcn@latest docs input button`:
-
-```
-base  radix
-
-input
-  docs      https://ui.shadcn.com/docs/components/radix/input
-  examples  https://raw.githubusercontent.com/.../examples/input-example.tsx
-
-button

-```
-
-Some components include an `api` link to the underlying library (e.g. `cmdk` for the command component).
-
-### `diff` — Check for updates
-
-Do not use this command. Use `npx shadcn@latest add --diff` instead.
-
-### `info` — Project information
-
-```bash
-npx shadcn@latest info [options]
-```
-
-Displays project info and `components.json` configuration. Run this first to discover the project's framework, aliases, Tailwind version, and resolved paths.

-## Templates
-
-| Value          | Framework      | Monorepo support |
-| -------------- | -------------- | ---------------- |
-| `next`         | Next.js        | Yes              |
-| `vite`         | Vite           | Yes              |
-| `start`        | TanStack Start | Yes              |
-| `react-router` | React Router   | Yes              |
-| `astro`        | Astro          | Yes              |
-| `laravel`      | Laravel        | No               |
-
-All templates support monorepo scaffolding via the `--monorepo` flag. When passed, the CLI uses a monorepo-specific template directory (e.g. `next-monorepo`, `vite-monorepo`). When neither `--monorepo` nor `--no-monorepo` is passed, the CLI prompts interactively. Laravel does not support monorepo scaffolding.
-
----
-
-## Presets
-
-Three ways to specify a preset via `--preset`:
-
-1. **Named:** `--preset base-nova` or `--preset radix-nova`
-2. **Code:** `--preset a2r6bw` (base62 string, starts with lowercase `a`)
-3. **URL:** `--preset "https://ui.shadcn.com/init?base=radix&style=nova&..."`
-
-> **IMPORTANT:** Never try to decode, fetch, or resolve preset codes manually. Preset codes are opaque — pass them directly to `npx shadcn@latest init --preset <code>` and let the CLI handle resolution.
-
-## Switching Presets
-
-Ask the user first: **reinstall**, **merge**, or **skip** existing components?
-
-- **Re-install** → `npx shadcn@latest init --preset <code> --force --reinstall`. Overwrites all component files with the new preset styles. Use when the user hasn't customized components.
-- **Merge** → `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to get the list of installed components and use the [smart merge workflow](./SKILL.md#updating-components) to update them one by one, preserving local changes. Use when the user has customized components.
-- **Skip** → `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS variables, leaves existing components as-is.

-# Customization & Theming
-
-Components reference semantic CSS variable tokens. Change the variables to change every component.
-
-## Contents
-
-- How it works (CSS variables → Tailwind utilities → components)
-- Color variables and OKLCH format
-- Dark mode setup
-- Changing the theme (presets, CSS variables)
-- Adding custom colors (Tailwind v3 and v4)
-- Border radius
-- Customizing components (variants, className, wrappers)
-- Checking for updates
-
----
-
-## How It Works
-
-1. CSS variables defined in `:root` (light) and `.dark` (dark mode).
-2. Tailwind maps them to utilities: `bg-primary`, `text-muted-foreground`, etc.
-3. Components use these utilities — changing a variable changes all components that reference it.
-
----
-
-## Color Variables
-
-Every color follows the `name` / `name-foreground` convention. The base variable is for backgrounds, `-foreground` is for text/icons on that background.
-
-| Variable                                     | Purpose                          |
-| -------------------------------------------- | -------------------------------- |
-| `--background` / `--foreground`              | Page background and default text |
-| `--card` / `--card-foreground`               | Card surfaces                    |
-| `--primary` / `--primary-foreground`         | Primary buttons and actions      |
-| `--secondary` / `--secondary-foreground`     | Secondary actions                |
-| `--muted` / `--muted-foreground`             | Muted/disabled states            |
-| `--accent` / `--accent-foreground`           | Hover and accent states          |
-| `--destructive` / `--destructive-foreground` | Error and destructive actions    |
-| `--border`                                   | Default border color             |
-| `--input`                                    | Form input borders               |
-| `--ring`                                     | Focus ring color                 |
-| `--chart-1` through `--chart-5`              | Chart/data visualization         |
-| `--sidebar-*`                                | Sidebar-specific colors          |
-| `--surface` / `--surface-foreground`         | Secondary surface                |
-
-Colors use OKLCH: `--primary: oklch(0.205 0 0)` where values are lightness (0–1), chroma (0 = gray), and hue (0–360).
-
----
-
-## Dark Mode
-
-Class-based toggle via `.dark` on the root element. In Next.js, use `next-themes`:
-
-```tsx
-import { ThemeProvider } from "next-themes"
-
-<ThemeProvider attribute="class" defaultTheme="system" enableSystem>
-  {children}
-</ThemeProvider>
-```
-
----
-
-## Changing the Theme
-
-```bash
-# Apply a preset code from ui.shadcn.com.
-npx shadcn@latest init --preset a2r6bw --force
-
-# Switch to a named preset.
-npx shadcn@latest init --preset radix-nova --force
-npx shadcn@latest init --reinstall  # update existing components to match
-
-# Use a custom theme URL.
-npx shadcn@latest init --preset "https://ui.shadcn.com/init?base=radix&style=nova&theme=blue&..." --force
-```
-
-Or edit CSS variables directly in `globals.css`.
-
----
-
-## Adding Custom Colors
-
-Add variables to the file at `tailwindCssFile` from `npx shadcn@latest info` (typically `globals.css`). Never create a new CSS file for this.
-
-```css
-/* 1. Define in the global CSS file. */
-:root {
-  --warning: oklch(0.84 0.16 84);
-  --warning-foreground: oklch(0.28 0.07 46);
-}
-.dark {
-  --warning: oklch(0.41 0.11 46);
-  --warning-foreground: oklch(0.99 0.02 95);
-}
-```
-
-```css
-/* 2a. Register with Tailwind v4 (@theme inline). */
-@theme inline {
-  --color-warning: var(--warning);
-  --color-warning-foreground: var(--warning-foreground);
-}
-```
-
-When `tailwindVersion` is `"v3"` (check via `npx shadcn@latest info`), register in `tailwind.config.js` instead:
-
-```js
-// 2b. Register with Tailwind v3 (tailwind.config.js).
-module.exports = {
-  theme: {
-    extend: {
-      colors: {
-        warning: "oklch(var(--warning) / <alpha-value>)",
-        "warning-foreground":
-          "oklch(var(--warning-foreground) / <alpha-value>)",
-      },
-    },
-  },
-}
-```
-
-```tsx
-// 3. Use in components.
-<div className="bg-warning text-warning-foreground">Warning</div>
-```
-
----
-
-## Border Radius
-
-`--radius` controls border radius globally. Components derive values from it (`rounded-lg` = `var(--radius)`, `rounded-md` = `calc(var(--radius) - 2px)`).
-
----
-
-## Customizing Components
-
-See also: [rules/styling.md](./rules/styling.md) for Incorrect/Correct examples.
-
-Prefer these approaches in order:
-
-### 1. Built-in variants
-
-```tsx
-<Button variant="outline" size="sm">Click</Button>
-```
-
-### 2. Tailwind classes via `className`
-
-```tsx
-<Card className="max-w-md mx-auto">...</Card>
-```
-
-### 3. Add a new variant
-
-Edit the component source to add a variant via `cva`:
-
-```tsx
-// components/ui/button.tsx
-warning: "bg-warning text-warning-foreground hover:bg-warning/90",
-```
-
-### 4. Wrapper components
-
-Compose shadcn/ui primitives into higher-level components:
-
-```tsx
-export function ConfirmDialog({ title, description, onConfirm, children }) {
-  return (
-    <AlertDialog>
-      <AlertDialogTrigger asChild>{children}</AlertDialogTrigger>
-      <AlertDialogContent>
-        <AlertDialogHeader>
-          <AlertDialogTitle>{title}</AlertDialogTitle>
-          <AlertDialogDescription>{description}</AlertDialogDescription>
-        </AlertDialogHeader>
-        <AlertDialogFooter>
-          <AlertDialogCancel>Cancel</AlertDialogCancel>
-          <AlertDialogAction onClick={onConfirm}>Confirm</AlertDialogAction>
-        </AlertDialogFooter>
-      </AlertDialogContent>
-    </AlertDialog>
-  )
-}
-```
-
----
-
-## Checking for Updates
-
-```bash
-npx shadcn@latest add button --diff
-```
-
-To preview exactly what would change before updating, use `--dry-run` and `--diff`:
-
-```bash
-npx shadcn@latest add button --dry-run        # see all affected files
-npx shadcn@latest add button --diff button.tsx # see the diff for a specific file
-```

-# shadcn MCP Server
-
-The CLI includes an MCP server that lets AI assistants search, browse, view, and install components from registries.
-
----
-
-## Setup
-
-```bash
-shadcn mcp        # start the MCP server (stdio)
-shadcn mcp init   # write config for your editor
-```
-
-Editor config files:
-
-| Editor | Config file |
-|--------|------------|
-| Claude Code | `.mcp.json` |
-| Cursor | `.cursor/mcp.json` |
-| VS Code | `.vscode/mcp.json` |
-| OpenCode | `opencode.json` |
-| Codex | `~/.codex/config.toml` (manual) |
-
----
-
-## Tools
-
-> **Tip:** MCP tools handle registry operations (search, view, install). For project configuration (aliases, framework, Tailwind version), use `npx shadcn@latest info` — there is no MCP equivalent.
-
-### `shadcn:get_project_registries`
-
-Returns registry names from `components.json`. Errors if no `components.json` exists.
-
-**Input:** none
-
-### `shadcn:list_items_in_registries`
-
-Lists all items from one or more registries.
-
-**Input:** `registries` (string[]), `limit` (number, optional), `offset` (number, optional)
-
-### `shadcn:search_items_in_registries`
-
-Fuzzy search across registries.
-
-**Input:** `registries` (string[]), `query` (string), `limit` (number, optional), `offset` (number, optional)
-
-### `shadcn:view_items_in_registries`
-
-View item details including full file contents.
-
-**Input:** `items` (string[]) — e.g. `["@shadcn/button", "@shadcn/card"]`
-
-### `shadcn:get_item_examples_from_registries`
-
-Find usage examples and demos with source code.
-
-**Input:** `registries` (string[]), `query` (string) — e.g. `"accordion-demo"`, `"button example"`
-
-### `shadcn:get_add_command_for_items`
-
-Returns the CLI install command.
-
-**Input:** `items` (string[]) — e.g. `["@shadcn/button"]`
-
-### `shadcn:get_audit_checklist`
-
-Returns a checklist for verifying components (imports, deps, lint, TypeScript).
-
-**Input:** none
-
----
-
-## Configuring Registries
-
-Registries are set in `components.json`. The `@shadcn` registry is always built-in.
-
-```json
-{
-  "registries": {
-    "@acme": "https://acme.com/r/{name}.json",
-    "@private": {
-      "url": "https://private.com/r/{name}.json",
-      "headers": { "Authorization": "Bearer ${MY_TOKEN}" }
-    }
-  }
-}
-```
-
-- Names must start with `@`.
-- URLs must contain `{name}`.
-- `${VAR}` references are resolved from environment variables.

-# Base vs Radix
-
-API differences between `base` and `radix`. Check the `base` field from `npx shadcn@latest info`.
-
-## Contents
-
-- Composition: asChild vs render
-- Button / trigger as non-button element
-- Select (items prop, placeholder, positioning, multiple, object values)
-- ToggleGroup (type vs multiple)
-- Slider (scalar vs array)
-- Accordion (type and defaultValue)
-
----
-
-## Composition: asChild (radix) vs render (base)
-
-Radix uses `asChild` to replace the default element. Base uses `render`. Don't wrap triggers in extra elements.
-
-**Incorrect:**
-
-```tsx
-<DialogTrigger>
-  <div>
-    <Button>Open</Button>
-  </div>
-</DialogTrigger>
-```
-
-**Correct (radix):**
-
-```tsx
-<DialogTrigger asChild>
-  <Button>Open</Button>
-</DialogTrigger>
-```
-
-**Correct (base):**
-
-```tsx
-<DialogTrigger render={<Button />}>Open</DialogTrigger>
-```
-
-This applies to all trigger and close components: `DialogTrigger`, `SheetTrigger`, `AlertDialogTrigger`, `DropdownMenuTrigger`, `PopoverTrigger`, `TooltipTrigger`, `CollapsibleTrigger`, `DialogClose`, `SheetClose`, `NavigationMenuLink`, `BreadcrumbLink`, `SidebarMenuButton`, `Badge`, `Item`.
-
----
-
-## Button / trigger as non-button element (base only)
-
-When `render` changes an element to a non-button (`<a>`, `<span>`), add `nativeButton={false}`.
-
-**Incorrect (base):** missing `nativeButton={false}`.
-
-```tsx
-<Button render={<a href="/docs" />}>Read the docs</Button>
-```
-
-**Correct (base):**
-
-```tsx
-<Button render={<a href="/docs" />} nativeButton={false}>
-  Read the docs
-</Button>
-```
-
-**Correct (radix):**
-
-```tsx
-<Button asChild>
-  <a href="/docs">Read the docs</a>
-</Button>
-```
-
-Same for triggers whose `render` is not a `Button`:
-
-```tsx
-// base.
-<PopoverTrigger render={<InputGroupAddon />} nativeButton={false}>
-  Pick date
-</PopoverTrigger>
-```
-
----
-
-## Select
-
-**items prop (base only).** Base requires an `items` prop on the root. Radix uses inline JSX only.
-
-**Incorrect (base):**
-
-```tsx
-<Select>
-  <SelectTrigger><SelectValue placeholder="Select a fruit" /></SelectTrigger>
-</Select>
-```
-
-**Correct (base):**
-
-```tsx
-const items = [
-  { label: "Select a fruit", value: null },
-  { label: "Apple", value: "apple" },
-  { label: "Banana", value: "banana" },
-]
-
-<Select items={items}>
-  <SelectTrigger>
-    <SelectValue />
-  </SelectTrigger>
-  <SelectContent>
-    <SelectGroup>
-      {items.map((item) => (
-        <SelectItem key={item.value} value={item.value}>{item.label}</SelectItem>
-      ))}
-    </SelectGroup>
-  </SelectContent>
-</Select>
-```
-
-**Correct (radix):**
-
-```tsx
-<Select>
-  <SelectTrigger>
-    <SelectValue placeholder="Select a fruit" />
-  </SelectTrigger>
-  <SelectContent>
-    <SelectGroup>
-      <SelectItem value="apple">Apple</SelectItem>
-      <SelectItem value="banana">Banana</SelectItem>
-    </SelectGroup>
-  </SelectContent>
-</Select>
-```
-
-**Placeholder.** Base uses a `{ value: null }` item in the items array. Radix uses `<SelectValue placeholder="...">`.
-
-**Content positioning.** Base uses `alignItemWithTrigger`. Radix uses `position`.
-
-```tsx
-// base.
-<SelectContent alignItemWithTrigger={false} side="bottom">
-
-// radix.
-<SelectContent position="popper">
-```
-
----
-
-## Select — multiple selection and object values (base only)
-
-Base supports `multiple`, render-function children on `SelectValue`, and object values with `itemToStringValue`. Radix is single-select with string values only.
-
-**Correct (base — multiple selection):**
-
-```tsx
-<Select items={items} multiple defaultValue={[]}>
-  <SelectTrigger>
-    <SelectValue>
-      {(value: string[]) => value.length === 0 ? "Select fruits" : `${value.length} selected`}
-    </SelectValue>
-  </SelectTrigger>
-  ...
-</Select>
-```
-
-**Correct (base — object values):**
-
-```tsx
-<Select defaultValue={plans[0]} itemToStringValue={(plan) => plan.name}>
-  <SelectTrigger>
-    <SelectValue>{(value) => value.name}</SelectValue>
-  </SelectTrigger>
-  ...
-</Select>
-```
-
----
-
-## ToggleGroup
-
-Base uses a `multiple` boolean prop. Radix uses `type="single"` or `type="multiple"`.
-
-**Incorrect (base):**
-
-```tsx
-<ToggleGroup type="single" defaultValue="daily">
-  <ToggleGroupItem value="daily">Daily</ToggleGroupItem>
-</ToggleGroup>
-```
-
-**Correct (base):**
-
-```tsx
-// Single (no prop needed), defaultValue is always an array.
-<ToggleGroup defaultValue={["daily"]} spacing={2}>
-  <ToggleGroupItem value="daily">Daily</ToggleGroupItem>
-  <ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
-</ToggleGroup>
-
-// Multi-selection.
-<ToggleGroup multiple>
-  <ToggleGroupItem value="bold">Bold</ToggleGroupItem>
-  <ToggleGroupItem value="italic">Italic</ToggleGroupItem>
-</ToggleGroup>
-```
-
-**Correct (radix):**
-
-```tsx
-// Single, defaultValue is a string.
-<ToggleGroup type="single" defaultValue="daily" spacing={2}>
-  <ToggleGroupItem value="daily">Daily</ToggleGroupItem>
-  <ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
-</ToggleGroup>
-
-// Multi-selection.
-<ToggleGroup type="multiple">
-  <ToggleGroupItem value="bold">Bold</ToggleGroupItem>
-  <ToggleGroupItem value="italic">Italic</ToggleGroupItem>
-</ToggleGroup>
-```
-
-**Controlled single value:**
-
-```tsx
-// base — wrap/unwrap arrays.
-const [value, setValue] = React.useState("normal")
-<ToggleGroup value={[value]} onValueChange={(v) => setValue(v[0])}>
-
-// radix — plain string.
-const [value, setValue] = React.useState("normal")
-<ToggleGroup type="single" value={value} onValueChange={setValue}>
-```
-
----
-
-## Slider
-
-Base accepts a plain number for a single thumb. Radix always requires an array.
-
-**Incorrect (base):**
-
-```tsx
-<Slider defaultValue={[50]} max={100} step={1} />
-```
-
-**Correct (base):**
-
-```tsx
-<Slider defaultValue={50} max={100} step={1} />
-```
-
-**Correct (radix):**
-
-```tsx
-<Slider defaultValue={[50]} max={100} step={1} />
-```
-
-Both use arrays for range sliders. Controlled `onValueChange` in base may need a cast:
-
-```tsx
-// base.
-const [value, setValue] = React.useState([0.3, 0.7])
-<Slider value={value} onValueChange={(v) => setValue(v as number[])} />
-
-// radix.
-const [value, setValue] = React.useState([0.3, 0.7])
-<Slider value={value} onValueChange={setValue} />
-```
-
----
-
-## Accordion
-
-Radix requires `type="single"` or `type="multiple"` and supports `collapsible`. `defaultValue` is a string. Base uses no `type` prop, uses `multiple` boolean, and `defaultValue` is always an array.
-
-**Incorrect (base):**
-
-```tsx
-<Accordion type="single" collapsible defaultValue="item-1">
-  <AccordionItem value="item-1">...</AccordionItem>
-</Accordion>
-```
-
-**Correct (base):**
-
-```tsx
-<Accordion defaultValue={["item-1"]}>
-  <AccordionItem value="item-1">...</AccordionItem>
-</Accordion>
-
-// Multi-select.
-<Accordion multiple defaultValue={["item-1", "item-2"]}>
-  <AccordionItem value="item-1">...</AccordionItem>
-  <AccordionItem value="item-2">...</AccordionItem>
-</Accordion>
-```
-
-**Correct (radix):**
-
-```tsx
-<Accordion type="single" collapsible defaultValue="item-1">
-  <AccordionItem value="item-1">...</AccordionItem>
-</Accordion>
-```

-
-## Items always inside their Group component
-
-Never render items directly inside the content container.
-
-**Incorrect:**
-
-```tsx
-<SelectContent>
-  <SelectItem value="apple">Apple</SelectItem>
-  <SelectItem value="banana">Banana</SelectItem>
-</SelectContent>
-```

-
-This applies to all group-based components:
-
-| Item | Group |
-|------|-------|
-| `SelectItem`, `SelectLabel` | `SelectGroup` |
-| `DropdownMenuItem`, `DropdownMenuLabel`, `DropdownMenuSub` | `DropdownMenuGroup` |
-| `MenubarItem` | `MenubarGroup` |
-| `ContextMenuItem` | `ContextMenuGroup` |
-| `CommandItem` | `CommandGroup` |
-
----
-
-## Callouts use Alert
-
-```tsx
-<Alert>
-  <AlertTitle>Warning</AlertTitle>
-  <AlertDescription>Something needs attention.</AlertDescription>
-</Alert>
-```
-
----

-  <EmptyHeader>
-    <EmptyMedia variant="icon"><FolderIcon /></EmptyMedia>
-    <EmptyTitle>No projects yet</EmptyTitle>
-    <EmptyDescription>Get started by creating a new project.</EmptyDescription>

-toast.success("Changes saved.")
-toast.error("Something went wrong.")
-toast("File deleted.", {
-  action: { label: "Undo", onClick: () => undoDelete() },
-})

-
----
-
-## Choosing between overlay components
-
-| Use case | Component |
-|----------|-----------|
-| Focused task that requires input | `Dialog` |
-| Destructive action confirmation | `AlertDialog` |
-| Side panel with details or filters | `Sheet` |
-| Mobile-first bottom panel | `Drawer` |
-| Quick info on hover | `HoverCard` |
-| Small contextual content on click | `Popover` |
-
----
-
-## Dialog, Sheet, and Drawer always need a Title
-
-`DialogTitle`, `SheetTitle`, `DrawerTitle` are required for accessibility. Use `className="sr-only"` if visually hidden.
-
-```tsx
-<DialogContent>
-  <DialogHeader>
-    <DialogTitle>Edit Profile</DialogTitle>
-    <DialogDescription>Update your profile.</DialogDescription>
-  </DialogHeader>
-  ...
-</DialogContent>

-
----
-
-## Card structure
-
-Use full composition — don't dump everything into `CardContent`:
-
-```tsx
-<Card>
-  <CardHeader>
-    <CardTitle>Team Members</CardTitle>
-    <CardDescription>Manage your team.</CardDescription>
-  </CardHeader>
-  <CardContent>...</CardContent>
-  <CardFooter>
-    <Button>Invite</Button>
-  </CardFooter>
-</Card>
-```
-
----
-
-## Button has no isPending or isLoading prop
-
-Compose with `Spinner` + `data-icon` + `disabled`:
-
-```tsx
-<Button disabled>
-  <Spinner data-icon="inline-start" />
-  Saving...
-</Button>
-```
-
----
-
-## TabsTrigger must be inside TabsList
-
-Never render `TabsTrigger` directly inside `Tabs` — always wrap in `TabsList`:
-
-```tsx
-<Tabs defaultValue="account">
-  <TabsList>
-    <TabsTrigger value="account">Account</TabsTrigger>
-    <TabsTrigger value="password">Password</TabsTrigger>
-  </TabsList>
-  <TabsContent value="account">...</TabsContent>
-</Tabs>
-```
-
----
-
-## Avatar always needs AvatarFallback
-
-Always include `AvatarFallback` for when the image fails to load:
-
-```tsx
-<Avatar>
-  <AvatarImage src="/avatar.png" alt="User" />
-  <AvatarFallback>JD</AvatarFallback>
-</Avatar>

-- Buttons inside inputs use InputGroup + InputGroupAddon
-- Option sets (2–7 choices) use ToggleGroup
-- FieldSet + FieldLegend for grouping related fields
-- Field validation and disabled states
-
----
-
-## Forms use FieldGroup + Field
-
-Always use `FieldGroup` + `Field` — never raw `div` with `space-y-*`:
-
-```tsx
-<FieldGroup>
-  <Field>
-    <FieldLabel htmlFor="email">Email</FieldLabel>
-    <Input id="email" type="email" />

-  <Field>
-    <FieldLabel htmlFor="password">Password</FieldLabel>
-    <Input id="password" type="password" />
-  </Field>
-</FieldGroup>
-```
-
-Use `Field orientation="horizontal"` for settings pages. Use `FieldLabel className="sr-only"` for visually hidden labels.
-
-**Choosing form controls:**
-
-- Simple text input → `Input`
-- Dropdown with predefined options → `Select`
-- Searchable dropdown → `Combobox`
-- Native HTML select (no JS) → `native-select`
-- Boolean toggle → `Switch` (for settings) or `Checkbox` (for forms)
-- Single choice from few options → `RadioGroup`
-- Toggle between 2–5 options → `ToggleGroup` + `ToggleGroupItem`
-- OTP/verification code → `InputOTP`
-- Multi-line text → `Textarea`
-
----
-
-## InputGroup requires InputGroupInput/InputGroupTextarea
-
-Never use raw `Input` or `Textarea` inside an `InputGroup`.
-
-**Incorrect:**
-
-```tsx
-<InputGroup>
-  <Input placeholder="Search..." />
-</InputGroup>
-```
-
-**Correct:**
-
-```tsx
-import { InputGroup, InputGroupInput } from "@/components/ui/input-group"
-
-<InputGroup>
-  <InputGroupInput placeholder="Search..." />
-</InputGroup>
-```
-
----
-
-## Buttons inside inputs use InputGroup + InputGroupAddon
-
-Never place a `Button` directly inside or adjacent to an `Input` with custom positioning.
-
-**Incorrect:**
-
-```tsx
-<div className="relative">
-  <Input placeholder="Search..." className="pr-10" />
-  <Button className="absolute right-0 top-0" size="icon">
-    <SearchIcon />
-  </Button>
-</div>
-```
-
-**Correct:**
-
-```tsx
-import { InputGroup, InputGroupInput, InputGroupAddon } from "@/components/ui/input-group"
-
-<InputGroup>
-  <InputGroupInput placeholder="Search..." />
-  <InputGroupAddon>
-    <Button size="icon">
-      <SearchIcon data-icon="inline-start" />
-    </Button>
-  </InputGroupAddon>
-</InputGroup>
-```
-
----
-
-## Option sets (2–7 choices) use ToggleGroup
-
-Don't manually loop `Button` components with active state.
-
-**Incorrect:**
-
-```tsx
-const [selected, setSelected] = useState("daily")
-
-<div className="flex gap-2">
-  {["daily", "weekly", "monthly"].map((option) => (
-    <Button
-      key={option}
-      variant={selected === option ? "default" : "outline"}
-      onClick={() => setSelected(option)}
-    >
-      {option}
-    </Button>
-  ))}
-</div>
-```
-
-**Correct:**
-
-```tsx
-import { ToggleGroup, ToggleGroupItem } from "@/components/ui/toggle-group"
-
-<ToggleGroup spacing={2}>
-  <ToggleGroupItem value="daily">Daily</ToggleGroupItem>
-  <ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
-  <ToggleGroupItem value="monthly">Monthly</ToggleGroupItem>
-</ToggleGroup>
-```
-
-Combine with `Field` for labelled toggle groups:
-
-```tsx
-<Field orientation="horizontal">
-  <FieldTitle id="theme-label">Theme</FieldTitle>
-  <ToggleGroup aria-labelledby="theme-label" spacing={2}>
-    <ToggleGroupItem value="light">Light</ToggleGroupItem>
-    <ToggleGroupItem value="dark">Dark</ToggleGroupItem>
-    <ToggleGroupItem value="system">System</ToggleGroupItem>
-  </ToggleGroup>
-</Field>
-```
-
-> **Note:** `defaultValue` and `type`/`multiple` props differ between base and radix. See [base-vs-radix.md](./base-vs-radix.md#togglegroup).
-
----
-
-## FieldSet + FieldLegend for grouping related fields
-
-Use `FieldSet` + `FieldLegend` for related checkboxes, radios, or switches — not `div` with a heading:
-
-```tsx
-<FieldSet>
-  <FieldLegend variant="label">Preferences</FieldLegend>
-  <FieldDescription>Select all that apply.</FieldDescription>
-  <FieldGroup className="gap-3">
-    <Field orientation="horizontal">
-      <Checkbox id="dark" />
-      <FieldLabel htmlFor="dark" className="font-normal">Dark mode</FieldLabel>
-    </Field>
-  </FieldGroup>
-</FieldSet>
-```
-
----
-
-## Field validation and disabled states
-
-Both attributes are needed — `data-invalid`/`data-disabled` styles the field (label, description), while `aria-invalid`/`disabled` styles the control.
-
-```tsx
-// Invalid.
-<Field data-invalid>
-  <FieldLabel htmlFor="email">Email</FieldLabel>
-  <Input id="email" aria-invalid />
-  <FieldDescription>Invalid email address.</FieldDescription>
-</Field>
-
-// Disabled.
-<Field data-disabled>
-  <FieldLabel htmlFor="email">Email</FieldLabel>
-  <Input id="email" disabled />
-</Field>
-```
-
-Works for all controls: `Input`, `Textarea`, `Select`, `Checkbox`, `RadioGroupItem`, `Switch`, `Slider`, `NativeSelect`, `InputOTP`.

-# Styling & Customization
-
-See [customization.md](../customization.md) for theming, CSS variables, and adding custom colors.
-
-## Contents
-
-- Semantic colors
-- Built-in variants first
-- className for layout only
-- No space-x-* / space-y-*
-- Prefer size-* over w-* h-* when equal
-- Prefer truncate shorthand
-- No manual dark: color overrides
-- Use cn() for conditional classes
-- No manual z-index on overlay components
-
----
-
-## Semantic colors
-
-**Incorrect:**
-
-```tsx
-<div className="bg-blue-500 text-white">
-  <p className="text-gray-600">Secondary text</p>
-</div>
-```
-
-**Correct:**
-
-```tsx
-<div className="bg-primary text-primary-foreground">
-  <p className="text-muted-foreground">Secondary text</p>
-</div>
-```
-
----
-
-## No raw color values for status/state indicators
-
-For positive, negative, or status indicators, use Badge variants, semantic tokens like `text-destructive`, or define custom CSS variables — don't reach for raw Tailwind colors.
-
-**Incorrect:**
-
-```tsx
-<span className="text-emerald-600">+20.1%</span>
-<span className="text-green-500">Active</span>
-<span className="text-red-600">-3.2%</span>
-```
-
-**Correct:**
-
-```tsx
-<Badge variant="secondary">+20.1%</Badge>
-<Badge>Active</Badge>
-<span className="text-destructive">-3.2%</span>
-```
-
-If you need a success/positive color that doesn't exist as a semantic token, use a Badge variant or ask the user about adding a custom CSS variable to the theme (see [customization.md](../customization.md)).
-
----
-
-## Built-in variants first
-
-**Incorrect:**
-
-```tsx
-<Button className="border border-input bg-transparent hover:bg-accent">
-  Click me
-</Button>
-```
-
-**Correct:**
-
-```tsx
-<Button variant="outline">Click me</Button>
-```
-
----
-
-## className for layout only
-
-Use `className` for layout (e.g. `max-w-md`, `mx-auto`, `mt-4`), **not** for overriding component colors or typography. To change colors, use semantic tokens, built-in variants, or CSS variables.
-
-**Incorrect:**
-
-```tsx
-<Card className="bg-blue-100 text-blue-900 font-bold">
-  <CardContent>Dashboard</CardContent>
-</Card>
-```
-
-**Correct:**
-
-```tsx
-<Card className="max-w-md mx-auto">
-  <CardContent>Dashboard</CardContent>
-</Card>
-```
-
-To customize a component's appearance, prefer these approaches in order:
-1. **Built-in variants** — `variant="outline"`, `variant="destructive"`, etc.
-2. **Semantic color tokens** — `bg-primary`, `text-muted-foreground`.
-3. **CSS variables** — define custom colors in the global CSS file (see [customization.md](../customization.md)).
-
----
-
-## No space-x-* / space-y-*
-
-Use `gap-*` instead. `space-y-4` → `flex flex-col gap-4`. `space-x-2` → `flex gap-2`.
-
-```tsx
-<div className="flex flex-col gap-4">
-  <Input />
-  <Input />
-  <Button>Submit</Button>
-</div>
-```
-
----
-
-## Prefer size-* over w-* h-* when equal
-
-`size-10` not `w-10 h-10`. Applies to icons, avatars, skeletons, etc.
-
----
-
-## Prefer truncate shorthand
-
-`truncate` not `overflow-hidden text-ellipsis whitespace-nowrap`.
-
----
-
-## No manual dark: color overrides
-
-Use semantic tokens — they handle light/dark via CSS variables. `bg-background text-foreground` not `bg-white dark:bg-gray-950`.
-
----
-
-## Use cn() for conditional classes
-
-Use the `cn()` utility from the project for conditional or merged class names. Don't write manual ternaries in className strings.
-
-**Incorrect:**
-
-```tsx
-<div className={`flex items-center ${isActive ? "bg-primary text-primary-foreground" : "bg-muted"}`}>
-```
-
-**Correct:**
-
-```tsx
-import { cn } from "@/lib/utils"
-
-<div className={cn("flex items-center", isActive ? "bg-primary text-primary-foreground" : "bg-muted")}>
-```
-
----
-
-## No manual z-index on overlay components
-
-`Dialog`, `Sheet`, `Drawer`, `AlertDialog`, `DropdownMenu`, `Popover`, `Tooltip`, `HoverCard` handle their own stacking. Never add `z-50` or `z-[999]`.

+
+## v1.0 UI/UX Overhaul (Shipped: 2026-03-24)
+
+**Phases completed:** 4 phases, 10 plans, 19 tasks
+
+**Key accomplishments:**
+
+- shadcn chart/collapsible primitives with Recharts v3 patch, two-tier OKLCH category colors, semantic budget status tokens, and bilingual dashboard i18n keys
+- PageShell, StatCard, SummaryStrip, and DashboardSkeleton components with semantic OKLCH color tokens replacing all hardcoded green/red values in DashboardPage

+## What This Is
+
+A self-hosted personal budget dashboard that replaces a manual spreadsheet workflow. It tracks monthly budgets with bills, variable expenses, debts, savings, and investments — presented in a dense, visually rich UI with OKLCH pastel colors, three chart types (donut, bar, horizontal bar), collapsible category sections, and consistent design across all 9 pages. Features a smart template system for recurring items, quick-add library for one-off expenses, and auto-generated budgets. Built with Go (backend) + React/TypeScript (frontend) + PostgreSQL.
+
+## Core Value
+
+Opening the app should feel like opening a beautifully designed personal spreadsheet — clean pastel colors, clear data layout, approachable and visually delightful. The UI IS the product.
+
+## Current Milestone: v2.0 UX Simplification & Design Rework
+
+**Goal:** Make the app intuitive and visually clean — template-driven budgeting with a sharp, minimal, pastel design system.
+
+**Target features:**
+- Design system overhaul — sharp edges, clear pastels, minimal whitespace-driven layout
+- Wizard-style template setup with pre-filled common items (rent, car insurance, groceries, etc.)
+- Category library with smart defaults and sensible pre-loaded amounts
+- Auto-created monthly budgets from template on first visit (no prompts)
+- Simplified budget view — add one-offs from category library directly (replaces quick-add page)
+- Dashboard = this month's budget at a glance (not chart overload)
+- Dashboard data fixes — spending/budget data correctly reflects user input
+
+## Current State
+
+**Shipped:** v1.0 (UI/UX Overhaul) + prior foundation (auth, CRUD, templates, quick-add)
+
+The app has a visual overhaul but the UX is poor — too many disconnected concepts (categories, templates, budgets, quick-add), the design feels clunky with excessive rounding, and the dashboard doesn't clearly show budget data. v2.0 simplifies the mental model to two concepts: "my template" and "this month's budget."
+

+
+### Active
+
+<!-- v2.0 scope — defined during milestone kickoff -->
+
+- [ ] Design system: sharp edges, clear pastels, minimal layout
+- [ ] Wizard-style template setup with smart defaults
+- [ ] Category library with pre-loaded common items
+- [ ] Auto-created monthly budgets from template
+- [ ] Simplified budget view with inline add-from-library
+- [ ] Dashboard shows current month's budget clearly
+- [ ] Dashboard data correctly reflects entered spending
+
+### Out of Scope
+
+- Recurring transaction automation — future feature
+- Spending alerts or notifications — future feature
+- Trend charts over months — future feature
+- Mobile-first optimization — desktop first, basic responsiveness only
+- CSV/bank import — future feature
+- Shared/household budgets — future feature
+- Dark mode — light mode pastel system first
+
+## Context
+
+v1.0 shipped a visual overhaul but the UX remains problematic. The user model has too many disconnected concepts — categories, templates, budgets, and quick-add are all separate pages with unclear relationships. The design system has excessive rounding and colors that aren't truly pastel. The dashboard shows charts but doesn't clearly reflect budget data the user entered.
+
+v2.0 simplifies to two user-facing concepts: "my template" (recurring budget structure with smart defaults) and "this month's budget" (auto-created from template, track actuals, add one-offs from library). The design shifts to sharp, minimal, clean pastels.
+
+Tech stack: Go 1.25 + React 19 + TypeScript + Tailwind CSS 4 + shadcn/ui + Recharts + PostgreSQL 16. Package manager: bun. Single Docker image via multi-stage build. Backend changes are in scope for this milestone where needed to support auto-creation and template-driven flow.
+
+## Constraints
+
+- **Tech stack**: Keep existing Go + React + shadcn/ui + Tailwind + Recharts stack
+- **Design system**: Build on shadcn/ui, customize via CSS variables and Tailwind config
+- **i18n**: All new/changed UI text must have de + en translations
+- **Package manager**: Use bun for frontend
+- **Platform**: Desktop web only — no mobile/tablet optimization
+
+## Key Decisions
+
+| Decision | Rationale | Outcome |
+|----------|-----------|---------|
+| UI overhaul only, no backend changes | Keep scope focused, ship faster, reduce risk | ✓ Good |
+| Desktop-first layout | Primary use case is desktop; basic responsive for mobile | ✓ Good |
+| Rich & colorful visual style | Match the visual density and appeal of the spreadsheet reference | ✓ Good |
+| Hybrid dashboard (summary + collapsible sections) | Best of both: quick overview with drill-down capability inline | ✓ Good |
+| All three chart types (bar, horizontal bar, donut) | Comprehensive financial visualization like the reference | ✓ Good |
+| Refresh all pages, not just dashboard | Consistent design language throughout the app | ✓ Good |
+| 4-phase roadmap: Foundation > Charts > Collapsibles > Full-app | Design tokens before components, dashboard before other pages | ✓ Good |
+| URL-based month navigation via useMonthParam | Survives refresh and enables sharing; uses ?month=YYYY-MM search param | ✓ Good |
+| 3-column responsive chart grid (md:2, lg:3) | Fits donut + 2 bar charts; collapses gracefully on smaller screens | ✓ Good |
+| DashboardContent as inner component pattern | Separates month selection/empty state from data-dependent chart rendering | ✓ Good |
+| Two-tier OKLCH category colors | Darker text (~0.55) for WCAG contrast, lighter fills (~0.65-0.70) for charts | ✓ Good |
+| CategorySection controlled open/onOpenChange pattern | Parent owns state for smart expand defaults and month-change reset | ✓ Good |
+| Auth card accent pattern (border-t-4 + favicon logo) | Consistent brand presence without heavy custom design | ✓ Good |
+| Direction-aware diff for all 6 category types | Spending over when actual > budget; income/saving over when actual < budget | ✓ Good |
+| Simplify to 2 user concepts: template + monthly budget | Categories/templates/budgets/quick-add too disconnected; users don't understand the flow | — Pending |
+| Sharp minimal design with clear pastels | v1.0 rounded/clunky design doesn't match the "clean spreadsheet" vision | — Pending |
+| Auto-create budgets from template on month visit | Removes friction; template is the source of truth | — Pending |
+| Wizard-style template setup with smart defaults | First-run must be intuitive; pre-filled common items reduce setup time | — Pending |
+
+## Evolution
+
+This document evolves at phase transitions and milestone boundaries.
+
+**After each phase transition** (via `/gsd:transition`):
+1. Requirements invalidated? → Move to Out of Scope with reason
+2. Requirements validated? → Move to Validated with phase reference
+3. New requirements emerged? → Add to Active
+4. Decisions to log? → Add to Key Decisions
+5. "What This Is" still accurate? → Update if drifted
+
+**After each milestone** (via `/gsd:complete-milestone`):
+1. Full review of all sections
+2. Core Value check — still the right priority?
+3. Audit Out of Scope — reasons still valid?
+4. Update Context with current state

+# Requirements: SimpleFinanceDash
+
+**Defined:** 2026-04-02
+**Core Value:** Opening the app should feel like opening a beautifully designed personal spreadsheet — clean pastel colors, clear data layout, approachable and visually delightful. The UI IS the product.
+
+## v2.0 Requirements
+
+Requirements for UX Simplification & Design Rework. Each maps to roadmap phases.
+
+### Design System
+
+- [ ] **DS-01**: User sees sharp-edged UI across all pages (no rounded corners)
+- [ ] **DS-02**: User sees clear pastel colors that are visibly colorful, not washed out
+- [ ] **DS-03**: User sees a clean, minimal layout with generous whitespace
+
+### Setup Wizard
+
+- [ ] **SETUP-01**: New user is guided through a 3-step wizard: income → recurring items → review
+- [ ] **SETUP-02**: User sees pre-filled common budget items with sensible default amounts (~15-20 items: rent, groceries, car insurance, utilities, etc.)
+- [ ] **SETUP-03**: User can skip any wizard step or the entire wizard
+- [ ] **SETUP-04**: User sees a live "remaining to allocate" balance updating as items are selected in the wizard
+- [ ] **SETUP-05**: User's template is created from wizard selections on completion
+
+### Auto-Budget
+
+- [ ] **AUTO-01**: User's monthly budget is auto-created from template when visiting a month for the first time
+- [ ] **AUTO-02**: User sees a toast notification on the first auto-creation only
+- [ ] **AUTO-03**: Auto-creation uses the user's configured currency, not a hardcoded default
+
+### Budget View
+
+- [ ] **BV-01**: User can add one-off items to the monthly budget via an inline sheet panel (from category library)
+- [ ] **BV-02**: Quick Add page is removed from navigation
+- [ ] **BV-03**: User sees empty state with clear CTA when template, budget, or dashboard is empty
+
+### Dashboard
+
+- [ ] **DASH-01**: Dashboard correctly displays budget and spending data the user entered
+- [ ] **DASH-02**: Dashboard shows this month's budget at a glance (simplified view, not chart overload)
+- [ ] **DASH-03**: Dashboard shows summary cards for income, expenses, and balance
+
+## v3 Requirements
+
+Deferred to future release. Tracked but not in current roadmap.
+
+### Analytics & Insights
+
+- **ANALYTICS-01**: User can see spending trends over months
+- **ANALYTICS-02**: User gets income-based spending recommendations by category
+
+### Integrations
+
+- **IMPORT-01**: User can import actuals from CSV/bank export
+- **IMPORT-02**: User can import recurring transactions automatically
+
+### Polish
+
+- **POLISH-01**: User can use the app in dark mode
+- **POLISH-02**: User sees "Review your template" prompt after 3 months of use
+- **POLISH-03**: User sees "Edit template" shortcut link from budget view
+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| AI-suggested budget amounts | Requires spending history that new users don't have; static defaults sufficient |
+| Mandatory wizard (no skip) | Anti-feature — patronizing for returning users; YNAB removed forced onboarding |
+| 6+ step wizard | Drop-off increases sharply beyond 3 steps |
+| Bank account sync (Plaid) | High infrastructure/security cost for self-hosted tool |
+| Shared/household budgets | Single-user app; future consideration |
+| Mobile-first optimization | Desktop-first; basic responsiveness only |
+| Keep Quick Add as separate page alongside inline add | Two surfaces for same action creates confusion |
+
+## Traceability
+
+Which phases cover which requirements. Updated during roadmap creation.
+
+| Requirement | Phase | Status |
+|-------------|-------|--------|
+| DS-01 | Phase 5 | Pending |

+# Project Retrospective
+
+*A living document updated after each milestone. Lessons feed forward into future planning.*
+
+## Milestone: v1.0 — UI/UX Overhaul
+
+**Shipped:** 2026-03-24
+**Phases:** 4 | **Plans:** 10 | **Tasks:** 19
+
+### What Was Built
+- OKLCH design system with two-tier category colors and semantic budget status tokens
+- Three chart types (expense donut, income bar, spend horizontal bar) with CSS variable theming
+- URL-based month navigation with MonthNavigator dropdown
+- Collapsible per-category dashboard sections with direction-aware diff and CSS animations
+- PageShell, StatCard, SummaryStrip shared components for consistent page structure
+- All 9 pages upgraded with consistent design, skeleton loading, and full i18n
+
+### What Worked
+- 4-phase dependency chain (foundation → charts → collapsibles → full-app) prevented rework
+- Research-first approach documented Recharts v3 patch and OKLCH patterns before planning
+- Pure presentational components (CategorySection, charts) made integration straightforward
+- Two-tier color approach (dark text, light fills) solved WCAG contrast without sacrificing aesthetics
+
+### What Was Inefficient
+- Plan 02-01 SUMMARY.md was never written, requiring retroactive artifact creation
+- Roadmap progress table fell out of sync (phases 3-4 completed but not marked in roadmap)
+- Divergence between local and remote branches required hard reset — lost v1.1 milestone work
+
+### Patterns Established
+- OKLCH two-tier pattern: ~0.55 lightness for text (WCAG), ~0.65-0.70 for chart fills
+- PageShell + skeleton pattern: every page gets PageShell header and matching skeleton
+- Direction-aware diff: SPENDING_TYPES array + isSpendingType() covers all 6 category types
+- Controlled collapsible state: parent owns open/close for smart defaults and month-change reset
+- Auth card accent: border-t-4 border-t-primary + favicon logo
+
+### Key Lessons
+1. Always verify remote state before starting new local work to avoid divergence
+2. Summary artifacts must be written immediately — retroactive creation loses context
+3. Roadmap progress tracking should be verified at milestone completion, not assumed correct
+
+### Cost Observations
+- Model mix: 100% quality profile (opus executors, sonnet verifiers)
+- Sessions: ~4-5 across the milestone
+- Notable: 10 plans across 4 phases completed in ~20 days with minimal rework

+# Roadmap: SimpleFinanceDash v2.0 — UX Simplification & Design Rework
+
+## Overview
+
+This milestone transforms SimpleFinanceDash from a visually polished but cognitively complex app into a guided, intuitive budgeting experience. Work flows from a global design token rework (sharp edges, clearer pastels) through data safety foundations, a wizard-driven first-run setup, automatic budget creation, and finally a simplified budget view with inline item adding. Every phase delivers a coherent, verifiable capability on top of the fully working v1.0 baseline.
+
+## Phases
+
+**Phase Numbering:**
+- Integer phases (5-9): v2.0 milestone work, continuing from v1.0's Phase 4
+- Decimal phases: Urgent insertions if needed (marked INSERTED)
+
+Decimal phases appear between their surrounding integers in numeric order.
+
+- [ ] **Phase 5: Design System Token Rework** - Replace rounded corners with sharp edges and refine OKLCH pastel tokens across all 9 pages
+- [x] **Phase 6: Preset Data, First-Run Detection, and DB Safety** - Seed preset library, build first-run hook, and add DB uniqueness constraints that protect against duplicate data
+- [x] **Phase 7: Setup Wizard** - 3-step first-run wizard with income, pre-filled recurring items, and review — skippable, state-persisted, bilingual (completed 2026-04-20)
+- [ ] **Phase 8: Auto-Budget Creation** - Auto-create current month's budget from template on dashboard visit, with correct currency and first-creation toast
+- [ ] **Phase 9: Inline Add and Dashboard Simplification** - Replace Quick Add page with inline Sheet panel, simplify dashboard to at-a-glance view, add empty states
+
+## Phase Details
+
+### Phase 5: Design System Token Rework
+**Goal**: Users see a sharp, minimal, clearly pastel UI across every page — the visual foundation that all subsequent phases build on
+**Depends on**: Phase 4 (v1.0 complete)
+**Requirements**: DS-01, DS-02, DS-03
+**Success Criteria** (what must be TRUE):
+  1. Every rounded element across all 9 pages has sharp corners — no pill buttons, no rounded cards, no rounded inputs visible anywhere in the app
+  2. Category color swatches are visibly colorful against white backgrounds — not washed-out or grey-tinted — and still pass WCAG 4.5:1 contrast for text
+  3. Page layouts feel uncluttered — content sections have consistent whitespace gaps and no visual crowding between cards or sections
+  4. A full visual pass of all 9 pages (Dashboard, Budget List, Budget Detail, Template, Categories, Quick Add, Settings, Login, Register) confirms no regressions from token changes
+**Plans:** 3 plans
+Plans:
+- [x] 05-01-PLAN.md — Design tokens (radius, colors, chart vars) and chart component Bar radius updates
+- [x] 05-02-PLAN.md — Shared component rounded-* removal and spacing upgrades (PageShell, DashboardSkeleton, CategorySection, ChartEmptyState, QuickAddPicker)
+- [x] 05-03-PLAN.md — Per-page sweep (all 9 pages) for rounded-* removal, spacing upgrades, and visual verification checkpoint
+
+### Phase 6: Preset Data, First-Run Detection, and DB Safety
+**Goal**: The data layer is safe and ready — duplicate budget/category writes are impossible at the DB level, and the app correctly identifies first-run users
+**Depends on**: Phase 5
+**Requirements**: AUTO-01, AUTO-03, SETUP-01, SETUP-02
+**Success Criteria** (what must be TRUE):
+  1. Attempting to create two budgets for the same user and month is rejected at the DB level (unique constraint on `budgets(user_id, start_date)`)
+  2. Attempting to create two categories with the same name for the same user is rejected at the DB level (unique constraint on `categories(user_id, name)`)
+  3. All existing v1.0 users have `profiles.setup_completed = true` after the backfill migration runs — they will not be shown the wizard on their next login
+  4. `useFirstRunState` hook returns `true` only for users with zero categories or zero template items — returning `false` for any user with existing data
+  5. `src/data/presets.ts` contains ~15-20 curated budget items with sensible default amounts, grouped by category type, with both English and German i18n translation keys defined
+**Plans:** 3 plans
+Plans:
+- [x] 06-01-PLAN.md — DB migrations (uniqueness constraints + setup_completed column + Profile type update)
+- [x] 06-02-PLAN.md — Preset library (src/data/presets.ts) and i18n translations (en.json + de.json)
+- [x] 06-03-PLAN.md — useFirstRunState hook, DB schema push, and verification checkpoint
+
+### Phase 7: Setup Wizard
+**Goal**: A new user can set up their budget template in under 3 minutes by following a guided 3-step wizard with pre-filled common items and a live running balance
+**Depends on**: Phase 6
+**Requirements**: SETUP-01, SETUP-02, SETUP-03, SETUP-04, SETUP-05
+**Success Criteria** (what must be TRUE):
+  1. A new user (zero categories, zero template items) is automatically redirected to `/setup` on their first login and sees a 3-step wizard: income entry, recurring items selection, and review
+  2. The recurring items step shows ~15-20 pre-filled common items (rent, groceries, car insurance, utilities, etc.) with editable default amounts — user can check or uncheck each
+  3. A "remaining to allocate" balance updates live as items are checked or unchecked in step 2, showing income minus the sum of selected item amounts
+  4. User can click "Skip" on any individual step or "Skip setup" to exit the wizard entirely without creating any data — and lands on the dashboard
+  5. Completing the wizard creates a populated template from selected items — user lands on the dashboard with their template in place, and refreshing the browser mid-wizard restores the wizard at the correct step
+**Plans:** 2/2 plans complete
+Plans:
+- [x] 07-01-PLAN.md — Wizard state hook, i18n keys, stepper + step 1/2 UI components (income, recurring items, allocation bar)
+- [x] 07-02-PLAN.md — ReviewStep, completion logic, skip handling, /setup route, first-run redirect, and verification checkpoint
+
+### Phase 8: Auto-Budget Creation
+**Goal**: Users never manually trigger budget creation — visiting a month for the first time automatically creates their budget from the template, silently and correctly
+**Depends on**: Phase 7
+**Requirements**: AUTO-01, AUTO-02, AUTO-03
+**Success Criteria** (what must be TRUE):
+  1. Navigating to the dashboard for a month that has no budget (but a populated template) creates the budget automatically — no button click or prompt required
+  2. The first time a budget is auto-created in a session, a toast notification appears naming the month and indicating it was created from the template — subsequent months are created silently
+  3. The auto-created budget uses the user's configured currency from their profile settings, not a hardcoded default
+  4. Rapidly navigating between months or opening the dashboard in two tabs does not produce duplicate budget rows
+**Plans:** 3 plans
+Plans:
+- [ ] 06-01-PLAN.md — DB migrations (uniqueness constraints + setup_completed column + Profile type update)
+- [ ] 06-02-PLAN.md — Preset library (src/data/presets.ts) and i18n translations (en.json + de.json)
+- [ ] 06-03-PLAN.md — useFirstRunState hook, DB schema push, and verification checkpoint
+
+### Phase 9: Inline Add and Dashboard Simplification
+**Goal**: Users add one-off items to their budget directly from the budget view, the Quick Add page is gone, and the dashboard shows this month's data at a glance without chart overload
+**Depends on**: Phase 8
+**Requirements**: BV-01, BV-02, BV-03, DASH-01, DASH-02, DASH-03
+**Success Criteria** (what must be TRUE):
+  1. An "Add item" control on the budget detail page opens a Sheet panel showing the category library — user selects a category, enters an amount, and the item appears in the budget without a page navigation
+  2. The Quick Add page is removed from the sidebar navigation — visiting `/quick-add` redirects to `/budgets` instead of showing an error
+  3. The dashboard displays this month's summary cards (income, expenses, balance) with correct totals that match what the user entered in the budget detail page
+  4. The dashboard does not show the 3-column chart grid by default — the primary view is the at-a-glance summary and collapsible category sections
+  5. Empty template, empty dashboard, and empty budget view each show a clear empty state with a visible call-to-action guiding the user to the next step
+**Plans:** 3 plans
+Plans:
+- [ ] 06-01-PLAN.md — DB migrations (uniqueness constraints + setup_completed column + Profile type update)
+- [ ] 06-02-PLAN.md — Preset library (src/data/presets.ts) and i18n translations (en.json + de.json)
+- [ ] 06-03-PLAN.md — useFirstRunState hook, DB schema push, and verification checkpoint

+Recent decisions affecting current work:
+
+- [Roadmap v2.0]: 5-phase structure — tokens first (global scope), DB safety before UI writes, wizard before auto-budget, auto-budget before inline add
+- [Roadmap v2.0]: Phase 6 kept separate from Phase 7 — DB constraints and backfill migration must land before any wizard UI to prevent data corruption
+- [Roadmap v2.0]: SETUP-01, SETUP-02, AUTO-01, AUTO-03 split across Phase 6 and Phase 7/8 — Phase 6 provides the prerequisite DB/data layer, later phases deliver user-visible behavior
+
+### Pending Todos
+
+None yet.
+
+### Blockers/Concerns
+
+- ⚠️ [Phase 8] Verify `profiles` table currency column name before writing auto-create code — check `supabase/migrations/001_profiles.sql` at planning time (research flagged this)
+- ⚠️ [Phase 6] `setup_completed` backfill migration must ship before Phase 7 deploys — existing v1.0 users must not see the wizard on first v2.0 login

+# Architecture
+
+**Analysis Date:** 2026-03-16
+
+## Pattern Overview
+
+**Overall:** Layered client-side SPA with React, using hooks for data access and state management through TanStack Query, centralized authentication with Supabase, and component-based UI rendering.
+
+**Key Characteristics:**
+- Three-tier vertical slice: Pages → Hooks → Library (Supabase + utilities)
+- TanStack Query for caching and synchronization of remote state
+- Route-based code organization with role-based access control (protected/public routes)
+- Supabase PostgreSQL backend with real-time subscriptions capability
+- Internationalization (i18n) at the root level with JSON resource files
+
+## Layers
+
+**Presentation Layer (Pages & Components):**
+- Purpose: Render UI, handle user interactions, coordinate component composition
+- Location: `src/pages/` and `src/components/`
+- Contains: Page components (DashboardPage, TemplatePage, BudgetListPage, etc.), UI primitives from `src/components/ui/`, and custom components (AppLayout, QuickAddPicker)
+- Depends on: Hooks, UI utilities, i18n, icons (lucide-react), formatting utilities
+- Used by: React Router for page routing
+
+**Hooks Layer (Data Access & State):**
+- Purpose: Encapsulate all server communication and query/mutation logic, manage request/response caching via TanStack Query
+- Location: `src/hooks/`
+- Contains: Custom hooks for each domain (useAuth, useCategories, useBudgets, useTemplate, useQuickAdd)
+- Depends on: Supabase client, TanStack Query, type definitions
+- Used by: Page and component layers for CRUD operations and state retrieval
+
+**Library Layer (Core Services & Utilities):**
+- Purpose: Provide primitive implementations, type definitions, and configuration
+- Location: `src/lib/`
+- Contains:
+  - `supabase.ts` - Supabase client initialization and environment validation
+  - `types.ts` - TypeScript interfaces for all domain entities (Profile, Category, Budget, BudgetItem, Template, TemplateItem, QuickAddItem)
+  - `format.ts` - Currency formatting using Intl.NumberFormat
+  - `palette.ts` - Category color mapping and labels (internationalized)
+  - `utils.ts` - General utilities
+- Depends on: Supabase SDK, TypeScript types
+- Used by: Hooks and components for types and helpers
+
+**Authentication Layer:**
+- Purpose: Manage session state and auth operations
+- Location: `src/hooks/useAuth.ts`
+- Implementation: Reactive Supabase auth listener with automatic session refresh
+- State: Session, user, loading flag
+- Operations: signUp, signIn, signInWithOAuth (Google, GitHub), signOut
+
+**Internationalization (i18n):**
+- Purpose: Provide multi-language support at runtime
+- Location: `src/i18n/index.ts` with JSON resource files (`en.json`, `de.json`)
+- Framework: react-i18next with i18next
+- Initialization: Automatic at app startup before any render
+
+## Data Flow
+
+**Read Pattern (Fetch & Display):**
+
+1. Component renders and mounts
+2. Component calls custom hook (e.g., `useBudgets()`, `useCategories()`)
+3. Hook initializes TanStack Query with async queryFn
+4. Query function calls Supabase table select with filters/joins
+5. Supabase returns typed rows from database
+6. Hook caches result in Query store with staleTime of 5 minutes
+7. Component receives `data`, `loading`, and error states
+8. Component renders based on data state
+9. Subsequent mounts of same component use cached data (until stale)
+
+**Write Pattern (Mutate & Sync):**
+
+1. Component invokes mutation handler (e.g., click "Save")
+2. Handler calls `mutation.mutateAsync(payload)`
+3. Mutation function marshals payload and calls Supabase insert/update/delete
+4. Supabase executes DB operation and returns modified row(s)
+5. Mutation onSuccess callback triggers Query invalidation
+6. Query re-fetches from server with fresh data
+7. Component re-renders with new cached data
+8. Toast notification indicates success or error
+
+**Real-time Budget Updates:**
+
+Example flow for editing a budget item (from `useBudgets.ts`):
+1. User edits amount in budget detail table → calls `updateItem.mutateAsync({ id, budgetId, budgeted_amount: X })`
+2. Hook serializes to Supabase `.update()` with .eq("id", id)
+3. Response contains updated BudgetItem with joined Category data
+4. onSuccess invalidates `["budgets", budgetId, "items"]` cache key
+5. DashboardContent's useBudgetDetail query re-fetches entire items array
+6. Component recalculates totals and re-renders pie chart and progress bars
+
+**State Management:**
+- No Redux or Zustand — TanStack Query handles async state
+- Local component state for UI interactions (dialogs, forms, selections)
+- Session state maintained by Supabase auth listener in useAuth hook
+- Cache invalidation is the primary sync mechanism
+
+## Key Abstractions
+
+**Query Key Pattern:**
+
+Each hook defines typed query keys as const arrays:
+- `["categories"]` - all user categories
+- `["budgets"]` - all user budgets
+- `["budgets", id]` - single budget
+- `["budgets", id, "items"]` - items for a specific budget
+- `["template"]` - user's monthly template
+- `["template-items"]` - items in template
+- `["quick-add"]` - user's quick-add library
+
+Purpose: Enables granular invalidation (e.g., update one budget doesn't refetch all budgets)
+
+**Mutation Factories:**
+
+Hooks expose mutations as properties of returned object:
+- `useCategories()` returns `{ categories, loading, create, update, remove }`
+- `useBudgets()` returns `{ budgets, loading, createBudget, generateFromTemplate, updateItem, createItem, deleteItem, deleteBudget }`
+
+Each mutation includes:
+- `mutationFn` - async operation against Supabase
+- `onSuccess` - cache invalidation strategy
+
+**Hook Composition:**
+
+`useBudgetDetail(id)` is both a standalone export and accessible via `useBudgets().getBudget(id)`:
+- Enables flexible usage patterns
+- Query with `.enabled: Boolean(id)` prevents queries when id is falsy
+- Used by DashboardPage to fetch current month's budget data
+
+**Type Hierarchy:**
+
+Core types in `src/lib/types.ts`:
+- `Profile` - user profile with locale and currency
+- `Category` - user-defined expense category
+- `Template` & `TemplateItem` - monthly budget template (fixed/variable items)
+- `Budget` & `BudgetItem` - actual budget with tracked actual/budgeted amounts
+- `QuickAddItem` - quick entry library for rapid data entry
+
+Relationships:
+- User → many Profiles (one per row, per user)
+- User → many Categories
+- User → one Template (auto-created)
+- Template → many TemplateItems → Category (join)
+- User → many Budgets (monthly)
+- Budget → many BudgetItems → Category (join)
+- User → many QuickAddItems
+
+## Entry Points
+
+**Application Root:**
+- Location: `src/main.tsx`
+- Initializes React 19 with context providers:
+  - QueryClientProvider (TanStack Query)
+  - BrowserRouter (React Router)
+  - TooltipProvider (Radix UI)
+  - Toaster (Sonner notifications)
+- Creates single QueryClient with 5-minute staleTime default
+
+**Route Configuration:**
+- Location: `src/App.tsx`
+- Defines protected and public routes
+- Protected routes wrapped in `ProtectedRoute` which checks auth state via `useAuth()`
+- Public routes wrapped in `PublicRoute` which redirects authenticated users away
+- Routes:
+  - `/login`, `/register` - public (redirect home if logged in)
+  - `/`, `/categories`, `/template`, `/budgets`, `/budgets/:id`, `/quick-add`, `/settings` - protected
+
+**Layout Root:**
+- Location: `src/components/AppLayout.tsx`
+- Renders Sidebar with navigation items (using Radix UI primitives)
+- Renders Outlet for nested route content
+- Provides sign-out button in footer
+
+**Page Entry Points:**
+
+Each page component is stateless renderer with logic split between:
+1. Page component (routing layer, layout)
+2. Sub-component(s) (content logic)
+3. Hook(s) (data fetching)
+
+Example: `DashboardPage.tsx` →
+- Main component finds current month's budget
+- Delegates to `DashboardContent` with `budgetId` prop
+- DashboardContent calls `useBudgetDetail(budgetId)` for data
+
+## Error Handling
+
+**Strategy:** Try-catch in mutation handlers with toast notifications for user feedback.
+
+**Patterns:**
+
+1. **Mutation Errors:**
+   - Try block executes `mutation.mutateAsync()`
+   - Catch block logs to console and shows `toast.error(t("common.error"))`
+   - Button remains clickable if error is transient
+   - Example in `TemplatePage.tsx` lines 182-204
+
+2. **Query Errors:**
+   - Query errors are captured by TanStack Query internally
+   - Hooks return loading state but not explicit error state
+   - Pages render null/loading state during failed queries
+   - Retry is configured to attempt once by default
+
+3. **Auth Errors:**
+   - `useAuth.ts` catches Supabase auth errors and re-throws
+   - LoginPage catches and displays error message in red text
+   - Session state remains null if auth fails
+
+4. **Missing Environment Variables:**
+   - `src/lib/supabase.ts` throws during module load if VITE_SUPABASE_URL or VITE_SUPABASE_ANON_KEY missing
+   - Prevents runtime errors from undefined client
+
+## Cross-Cutting Concerns
+
+**Logging:**
+Minimal logging — relies on:
+- Browser DevTools React Query Devtools (installable)
+- Console errors from try-catch blocks
+- Sonner toast notifications for user-facing issues
+
+**Validation:**
+- Input validation in mutation handlers (e.g., category ID check, amount > 0)
+- Type validation via TypeScript compile-time
+- Supabase schema constraints (NOT NULL, FOREIGN KEY, CHECK constraints)
+- Database uniqueness constraints (e.g., one template per user)
+
+**Authentication:**
+- Supabase session token stored in localStorage (browser SDK default)
+- Auth state checked at page render time via `useAuth()` hook
+- Protected routes redirect unauthenticated users to /login
+- Session persists across page refreshes (Supabase handles recovery)
+
+**Authorization:**
+- Row-level security (RLS) policies on Supabase tables enforce user_id filters
+- No explicit authorization logic in client (relies on DB policies)
+- All queries filter by current user via `await supabase.auth.getUser()`

+# Codebase Concerns
+
+**Analysis Date:** 2026-03-16
+
+## Tech Debt
+
+**Unsafe Type Assertions:**
+- Issue: Environment variables are cast with `as string` without runtime validation
+- Files: `src/lib/supabase.ts`
+- Impact: If environment variables are missing or undefined, the application will fail at runtime with cryptic errors instead of clear validation
+- Fix approach: Implement proper environment variable validation at startup with descriptive error messages. Use a validation function or schema validator (e.g., Zod) to ensure all required env vars are present and properly typed before using them.
+
+**Unvalidated Supabase Query Results:**
+- Issue: Database query results are cast to types with `as Type` without validation (e.g., `data as Budget[]`, `data as Category[]`)
+- Files: `src/hooks/useBudgets.ts`, `src/hooks/useTemplate.ts`, `src/hooks/useCategories.ts`, `src/hooks/useQuickAdd.ts`
+- Impact: If database schema changes or returns unexpected data structure, application could crash silently or display incorrect data. Type casting bypasses TypeScript safety.
+- Fix approach: Add runtime validation using Zod or similar schema validation library. Define schemas for all database types and validate responses before casting.
+
+**Hardcoded Date Logic Without Timezone Handling:**
+- Issue: Date calculations in `monthBounds()` and budget queries use local timezone without explicit handling
+- Files: `src/hooks/useBudgets.ts` (line 27-42), `src/pages/DashboardPage.tsx` (line 37-39)
+- Impact: Users in different timezones may see incorrect month boundaries. Budget dates could be off by one day depending on user timezone.
+- Fix approach: Use a date library like `date-fns` or `Day.js` with explicit timezone support. Store all dates in UTC and format for display based on user locale.
+
+**No Error Boundary Component:**
+- Issue: Application has no React Error Boundary to catch and handle rendering errors gracefully
+- Files: `src/App.tsx`, `src/components/AppLayout.tsx`
+- Impact: A single component error can crash the entire application without user feedback. No recovery mechanism.
+- Fix approach: Implement an Error Boundary wrapper at the root level and key sections to gracefully display fallback UI and log errors.
+
+## Known Bugs
+
+**Query Invalidation Race Conditions:**
+- Symptoms: When mutations complete, related queries are invalidated but may not refetch before components re-render
+- Files: `src/hooks/useBudgets.ts`, `src/hooks/useTemplate.ts`, `src/hooks/useCategories.ts`
+- Trigger: Rapid mutations on related data (e.g., updating template items then immediately viewing budget detail)
+- Workaround: Manually refetch or await invalidation before navigation
+
+**Logout Doesn't Clear Cache:**
+- Symptoms: After logout, if user logs back in as different user, old data may still be visible momentarily
+- Files: `src/hooks/useAuth.ts`, `src/components/AppLayout.tsx`
+- Trigger: User logs out, then logs in as different account
+- Workaround: Clear QueryClient cache on logout
+
+**Missing Bounds Check on Inline Edits:**
+- Symptoms: User can enter negative numbers or extremely large numbers in inline edit cells
+- Files: `src/pages/BudgetDetailPage.tsx` (InlineEditCell component)
+- Trigger: User enters invalid amount in inline editor
+- Workaround: Client-side validation only; no server-side constraints shown
+
+## Security Considerations
+
+**Unauthenticated Supabase Client Exposed:**
+- Risk: Application uses public anon key for Supabase, all clients share same authentication
+- Files: `src/lib/supabase.ts`
+- Current mitigation: Supabase RLS policies on database tables
+- Recommendations: Verify RLS policies are correctly set on ALL tables. Test that users cannot access other users' data through direct API calls. Consider using service role key for sensitive operations and server-side validation.
+
+**No Input Validation on User-Provided Data:**
+- Risk: Category names, template names, quick-add names accepted without validation or sanitization
+- Files: `src/pages/CategoriesPage.tsx`, `src/pages/TemplatePage.tsx`, `src/pages/QuickAddPage.tsx`, `src/components/QuickAddPicker.tsx`
+- Current mitigation: Input length limited by UI
+- Recommendations: Add server-side validation for text length, character restrictions, and XSS prevention. Sanitize data before display.
+
+**No Rate Limiting on Mutations:**
+- Risk: User can spam API with unlimited mutations (create, update, delete operations)
+- Files: All hook files with mutations
+- Current mitigation: None
+- Recommendations: Implement client-side debouncing and server-side rate limiting per user. Add confirmation dialogs for destructive operations.
+
+**Cleartext Storage of Sensitive Data:**
+- Risk: Notes field on budget items can contain sensitive information but has no encryption
+- Files: `src/pages/BudgetDetailPage.tsx` (notes field)
+- Current mitigation: None
+- Recommendations: Add encryption for notes field or implement field-level access control via RLS.
+
+## Performance Bottlenecks
+
+**Inefficient Pie Chart Rendering on Large Budgets:**
+- Problem: PieChart component recalculates and re-renders on every data change without memoization
+- Files: `src/pages/DashboardPage.tsx` (lines 104-109, Pie chart rendering)
+- Cause: Pie chart data transformation happens during render, component not memoized
+- Improvement path: Memoize chart data calculations with `useMemo()`. Consider moving heavy computations outside render.
+
+**Category Lookup O(n) on Every Item:**
+- Problem: Every budget item with category data requires iterating through categories array in filters
+- Files: `src/pages/DashboardPage.tsx`, `src/pages/BudgetDetailPage.tsx`
+- Cause: Using `filter()` and `reduce()` in render logic without memoization or indexing
+- Improvement path: Create a category index Map in a custom hook. Memoize grouped/filtered results.
+
+**No Pagination on Long Lists:**
+- Problem: All budgets, categories, and quick-add items load at once. No pagination or virtualization.
+- Files: `src/pages/BudgetListPage.tsx`, `src/pages/CategoriesPage.tsx`, `src/pages/QuickAddPage.tsx`
+- Cause: Supabase queries fetch all rows without limit
+- Improvement path: Implement pagination with `.range()` in queries. For very large lists, use virtual scrolling.
+
+**Sidebar Component Overcomplicated:**
+- Problem: Sidebar UI component is 724 lines with extensive state and conditional logic
+- Files: `src/components/ui/sidebar.tsx`
+- Cause: Radix UI base component with full feature set
+- Improvement path: Extract mobile/desktop logic into separate custom hooks. Consider if full sidebar complexity is needed.
+
+## Fragile Areas
+
+**Budget Month Lookup Logic:**
+- Files: `src/pages/DashboardPage.tsx` (lines 285-289), `src/hooks/useBudgets.ts` (line 28-32)
+- Why fragile: String prefix matching on dates to find current month budget. If date format changes, breaks silently.
+- Safe modification: Create dedicated date utility functions with tests. Use date library comparison instead of string prefixes.
+- Test coverage: No unit tests for monthBounds or month lookup logic
+
+**QuickAddPicker Multi-Dialog State:**
+- Files: `src/components/QuickAddPicker.tsx`
+- Why fragile: Manages two modal states (popover + dialog) with multiple interdependent state variables. Easy to get out of sync.
+- Safe modification: Refactor into a state machine pattern or context provider. Create helper function to reset all state.
+- Test coverage: No tests for state transitions or edge cases (e.g., closing popover while dialog open)
+
+**Inline Edit Cell Implementation:**
+- Files: `src/pages/BudgetDetailPage.tsx` (lines 68-133)
+- Why fragile: `useRef` with imperative focus, async commit logic could leave cell in inconsistent state on error
+- Safe modification: Add error handling in commit() to reset editing state. Use useCallback to memoize handlers.
+- Test coverage: No tests for edit flow, cancellation, or blur behavior
+
+**Template Item Reordering:**
+- Files: `src/hooks/useTemplate.ts` (lines 174-189)
+- Why fragile: Uses Promise.all for batch updates, first error stops entire operation but leaves partial state
+- Safe modification: Implement transaction-like behavior or rollback on error. Show partial success/failure feedback.
+- Test coverage: No tests for concurrent updates or error scenarios
+
+**Date Parsing in Budget Heading:**
+- Files: `src/pages/BudgetDetailPage.tsx` (lines 275-280)
+- Why fragile: Splits date string and uses `map(Number)` which could silently fail if date format changes
+- Safe modification: Use date parsing library. Add validation for date format.
+- Test coverage: No tests for date format parsing
+
+## Scaling Limits
+
+**QueryClient Cache Without Limits:**
+- Current capacity: Unbounded cache growth with every mutation
+- Limit: Long sessions could consume significant memory with stale cached data
+- Scaling path: Implement QueryClient cache configuration with GC time, stale time, and maximum cache size
+
+**No Database Indexing Strategy Documented:**
+- Current capacity: Unknown if queries will scale beyond thousands of items
+- Limit: Performance degradation as user data grows
+- Scaling path: Add database indexes on user_id, category_id, budget_id fields. Document query patterns.
+
+**Sidebar Component Renders Full Navigation on Every App Load:**
+- Current capacity: Works fine with <10 navigation items
+- Limit: Could become slow if navigation items scale to hundreds
+- Scaling path: Implement menu virtualization or lazy loading for navigation items
+
+## Dependencies at Risk
+
+**React Query (TanStack Query) Version Lock:**
+- Risk: Fixed to v5.90.21, major version bumps require API migration
+- Impact: Security fixes in newer versions require full refactor
+- Migration plan: Create abstraction layer for React Query hooks to isolate API. Plan quarterly dependency updates.
+
+**Supabase SDK Not Version-Locked:**
+- Risk: Using ^2.99.1 allows minor/patch updates that could introduce breaking changes
+- Impact: Unexpected behavior in authentication or database operations
+- Migration plan: Pin to exact version during development, test thoroughly before minor version upgrades
+
+**Recharts for Charts:**
+- Risk: Limited customization without ejecting to custom D3
+- Impact: Cannot easily implement complex financial chart types needed in future
+- Migration plan: Consider migrating to Chart.js or Visx if advanced charting requirements emerge
+
+## Missing Critical Features
+
+**No Data Export:**
+- Problem: Users cannot export budgets or transaction data
+- Blocks: Users cannot do external analysis, tax reporting, or data portability
+
+**No Recurring Transactions:**
+- Problem: Each month requires manual budget recreation or template generation
+- Blocks: Can't model monthly recurring expenses that auto-populate
+
+**No Budget Archival:**
+- Problem: Old budgets accumulate in database, no way to hide or delete safely
+- Blocks: UI becomes cluttered, performance degrades
+
+**No Audit Trail:**
+- Problem: No tracking of who changed what and when
+- Blocks: Cannot debug data inconsistencies or provide accountability
+
+**No Multi-Device Sync:**
+- Problem: Offline support or sync conflicts not handled
+- Blocks: Mobile app development would be difficult
+
+## Test Coverage Gaps
+
+**No Unit Tests:**
+- What's not tested: All business logic, date calculations, budget math, filter/reduce operations
+- Files: `src/hooks/`, `src/lib/`
+- Risk: Regression in calculation logic could go unnoticed (e.g., budget overage math, currency rounding)
+- Priority: High - calculation errors directly impact financial data
+
+**No Integration Tests:**
+- What's not tested: Mutation sequences, error recovery, cache invalidation, query dependencies
+- Files: All pages that use multiple mutations
+- Risk: Race conditions and inconsistent state when multiple operations happen quickly
+- Priority: High - production data corruption risk
+
+**No Component Tests:**
+- What's not tested: Inline edit cells, modal state management, form validation, error states
+- Files: `src/pages/BudgetDetailPage.tsx`, `src/components/QuickAddPicker.tsx`
+- Risk: UI behavior breaks silently (e.g., edit not saving, delete confirmation not working)
+- Priority: Medium - affects user experience
+
+**No E2E Tests:**
+- What's not tested: Complete user workflows (login → create budget → add items → view dashboard)
+- Risk: Critical paths fail only in production
+- Priority: Medium - would catch integration failures early
+
+**No Error Path Testing:**
+- What's not tested: Network errors, auth failures, database errors, invalid data
+- Files: All mutation handlers use generic toast.error() without specific handling
+- Risk: Users see unhelpful error messages, cannot recover gracefully
+- Priority: Medium - impacts user experience and debugging

+# Coding Conventions
+
+**Analysis Date:** 2026-03-16
+
+## Naming Patterns
+
+**Files:**
+- React components: PascalCase with .tsx extension - `QuickAddPicker.tsx`, `LoginPage.tsx`
+- Custom hooks: camelCase starting with "use" with .ts extension - `useAuth.ts`, `useCategories.ts`, `useBudgets.ts`
+- Utilities and type files: camelCase with .ts extension - `utils.ts`, `types.ts`, `format.ts`, `palette.ts`
+- UI components: lowercase with hyphens for compound names - `button.tsx`, `dropdown-menu.tsx`, `alert-dialog.tsx`
+- Directories: lowercase with hyphens for multi-word names - `components/ui`, `pages`, `hooks`, `lib`
+
+**Functions:**
+- React components: PascalCase - `QuickAddPicker`, `LoginPage`, `AppLayout`
+- Hook functions: camelCase with "use" prefix - `useAuth()`, `useIsMobile()`, `useBudgets()`
+- Utility functions: camelCase - `cn()`, `formatCurrency()`, `monthBounds()`
+- Event handlers: camelCase starting with "handle" - `handlePickItem()`, `handleSave()`, `handleDialogClose()`
+- Private/internal helpers: lowercase with underscore prefix when needed or nested as sub-functions
+
+**Variables:**
+- State variables: camelCase - `session`, `user`, `loading`, `popoverOpen`, `selectedItem`
+- Constants: UPPER_SNAKE_CASE - `MOBILE_BREAKPOINT`, `CATEGORY_TYPES`, `BUDGETS_KEY`
+- Query keys: lowercase with underscores - `budgets`, `categories`, `templates`
+- Boolean variables: descriptive names - `isMobile`, `canSave`, `loading`, `isLoading`
+
+**Types:**
+- Interfaces: PascalCase - `Profile`, `Category`, `Budget`, `BudgetItem`
+- Type unions: PascalCase or vertical bar notation - `type CategoryType = "income" | "bill" | ...`
+- Generic parameters: single uppercase letter or descriptive PascalCase - `T`, `Data`
+
+## Code Style
+
+**Formatting:**
+- No explicit formatter configured, but code follows consistent patterns
+- 2-space indentation (standard TypeScript/JavaScript practice)
+- Multiline imports organized by source type
+- Trailing commas in multiline arrays and objects
+- Semicolons at end of statements
+
+**Linting:**
+- Tool: ESLint (version 9.39.4) with Flat Config
+- Config: `eslint.config.js`
+- Extends: `@eslint/js`, `typescript-eslint`, `eslint-plugin-react-hooks`, `eslint-plugin-react-refresh`
+- Key rules enforced:
+  - React hooks best practices (`react-hooks/rules-of-hooks`)
+  - React refresh compatibility checks
+  - TypeScript recommended rules
+
+## Import Organization
+
+**Order:**
+1. React imports and hooks - `import { useState } from "react"`
+2. Third-party libraries - `import { useQuery } from "@tanstack/react-query"`
+3. Supabase imports - `import { supabase } from "@/lib/supabase"`
+4. Internal types - `import type { Category } from "@/lib/types"`
+5. Internal utilities - `import { cn } from "@/lib/utils"`
+6. Components - `import { Button } from "@/components/ui/button"`
+7. Other imports - hooks, constants, etc.
+
+**Path Aliases:**
+- `@/*` resolves to `./src/*` (configured in `tsconfig.app.json`)
+- Relative imports used only for co-located files
+- All absolute imports use the `@/` prefix
+
+**Example pattern from `QuickAddPicker.tsx`:**
+```typescript
+import { useState } from "react"
+import { useTranslation } from "react-i18next"
+import { Zap } from "lucide-react"
+import { toast } from "sonner"
+import { useQuickAdd } from "@/hooks/useQuickAdd"
+import { useCategories } from "@/hooks/useCategories"
+import { useBudgets } from "@/hooks/useBudgets"
+import type { QuickAddItem, CategoryType } from "@/lib/types"
+import { categoryColors } from "@/lib/palette"
+import { Button } from "@/components/ui/button"
+```
+
+## Error Handling
+
+**Patterns:**
+- Supabase errors checked with `if (error) throw error` pattern
+- Async/await used for promises with try/catch at caller level
+- User-facing errors converted to toast notifications using `sonner`
+- Authentication errors throw and are caught in component try/catch blocks
+- Validation errors prevented via state checks before action (`canSave` boolean pattern)
+
+**Example from `useCategories.ts`:**
+```typescript
+const { data, error } = await supabase.from("categories").select("*")
+if (error) throw error
+return data as Category[]
+```
+
+**Example from `LoginPage.tsx`:**
+```typescript
+try {
+  await signIn(email, password)
+  navigate("/")
+} catch (err) {
+  setError(err instanceof Error ? err.message : t("common.error"))
+}
+```
+
+## Logging
+
+**Framework:** No structured logging library. Uses standard browser console methods implicitly.
+
+**Patterns:**
+- No verbose console.log calls in code
+- Relies on error boundaries and try/catch for debugging
+- Toast notifications (via `sonner`) for user feedback on async operations
+- Translation keys used for all user-facing messages
+
+**Example from `QuickAddPicker.tsx`:**
+```typescript
+catch {
+  toast.error(t("common.error"))
+}
+```
+
+## Comments
+
+**When to Comment:**
+- Complex business logic documented with block comments
+- Multi-step mutations explained with numbered sections
+- Props documented with JSDoc-style comments on interfaces
+- Section separators used to organize large components (see 80+ line files)
+
+**JSDoc/TSDoc:**
+- Used on exported functions and interfaces
+- Describes purpose, parameters, and return values
+- Example from `useBudgets.ts`:
+```typescript
+/**
+ * Given a 1-based month and a full year, return ISO date strings for the
+ * first and last day of that month.
+ */
+function monthBounds(
+  month: number,
+  year: number
+): { start_date: string; end_date: string }
+```
+
+**Documentation Comments on Props:**
+```typescript
+interface QuickAddPickerProps {
+  /** The id of the current month's budget to add the item to. */
+  budgetId: string
+}
+```
+
+## Function Design
+
+**Size:** Functions kept under 100 lines; larger components organized with comment sections
+
+**Parameters:**
+- Single simple types preferred
+- Object destructuring for multiple related parameters
+- Type annotations always present for parameters
+- Optional parameters marked with `?:`
+
+**Return Values:**
+- Hooks return objects with destructurable properties
+- Components return JSX.Element
+- Explicit return type annotations on typed functions
+- null/undefined handled explicitly in return statements
+
+**Example pattern from `useBudgets.ts`:**
+```typescript
+return {
+  budgets: budgetsQuery.data ?? [],
+  loading: budgetsQuery.isLoading,
+  getBudget,
+  createBudget,
+  generateFromTemplate,
+  updateItem,
+  createItem,
+  deleteItem,
+  deleteBudget,
+}
+```
+
+## Module Design
+
+**Exports:**
+- Named exports for utility functions - `export function cn(...)`
+- Default exports for React components - `export default function QuickAddPicker`
+- Type-only exports for TypeScript types - `export type CategoryType = ...`
+- Multiple related hooks exported from single file - `useBudgets()` and `useBudgetDetail()` from same file
+
+**Barrel Files:**
+- Not used; imports reference specific files directly
+- Example: `import { Button } from "@/components/ui/button"` not from `@/components/ui`
+
+**File Organization:**
+- One main export per file
+- Related utilities and helpers in same file with clear section comments
+- Query key constants defined at top of custom hooks before the hook itself
+
+## TypeScript Configuration
+
+**Strict Mode:** Enabled (`"strict": true`)
+- All implicit `any` types caught
+- Null and undefined checking enforced
+- Type assertions allowed but discouraged
+
+**Key Options (`tsconfig.app.json`):**
+- Target: ES2023
+- Module: ESNext
+- JSX: react-jsx (React 17+ transform)
+- Strict mode enabled
+- `noUnusedLocals` and `noUnusedParameters` enforced
+- Path aliases configured for `@/*`
+
+## React Patterns
+
+**Hooks:**
+- `useState` for local component state
+- `useEffect` for side effects with proper cleanup
+- Custom hooks for data fetching and logic reuse
+- `useTranslation` from react-i18next for i18n
+- `useQueryClient` from @tanstack/react-query for cache invalidation
+
+**Component Structure:**
+- Functional components only
+- Props typed with TypeScript interfaces
+- Event handlers defined as functions (not inline)
+- Section comments separate concerns (Constants, Props, Render)
+
+**Forms:**
+- Controlled inputs with onChange handlers
+- Form submission prevents default with `e.preventDefault()`
+- Validation done before mutation execution
+- Error state displayed to user via toast or error field
+
+## Data Validation
+
+**Approach:** Type safety first with TypeScript
+- All data from Supabase cast with `as Type` after type-safe query
+- Input validation in component state checks before action
+- Zod not used; relies on TypeScript types and Supabase schema
+- Client-side checks prevent invalid mutations from firing
+
+**Example from `QuickAddPicker.tsx`:**
+```typescript
+const canSave =
+  Boolean(categoryId) &&
+  Boolean(amount) &&
+  !isNaN(parseFloat(amount)) &&
+  parseFloat(amount) >= 0
+```

+# External Integrations
+
+**Analysis Date:** 2026-03-16
+
+## APIs & External Services
+
+**Supabase Backend:**
+- Supabase - Primary backend-as-a-service platform
+  - SDK/Client: `@supabase/supabase-js` 2.99.1
+  - Auth: Environment variables `VITE_SUPABASE_URL` and `VITE_SUPABASE_ANON_KEY`
+  - Client initialization: `src/lib/supabase.ts`
+
+## Data Storage
+
+**Databases:**
+- PostgreSQL (Supabase hosted)
+  - Connection: Via `supabase` client in `src/lib/supabase.ts`
+  - Client: Supabase JavaScript SDK
+  - Tables: profiles, categories, templates, budgets, quick_add
+  - Row-level security (RLS) enabled on all user data tables
+  - Auto-trigger on signup: `handle_new_user()` creates user profile
+
+**Migrations:**
+- Location: `supabase/migrations/`
+- `001_profiles.sql` - User profiles with display name, locale, currency preferences
+- `002_categories.sql` - Transaction category definitions
+- `003_templates.sql` - Expense templates
+- `004_budgets.sql` - Budget management
+- `005_quick_add.sql` - Quick transaction templates
+
+**File Storage:**
+- Not detected (no file upload functionality)
+
+**Caching:**
+- React Query client-side caching
+  - Stale time: 5 minutes for queries
+  - Retry: 1 attempt on failure
+  - Configuration: `src/main.tsx`
+
+## Authentication & Identity
+
+**Auth Provider:**
+- Supabase Authentication
+  - Implementation: Email/password and OAuth (Google, GitHub)
+  - Hook: `src/hooks/useAuth.ts`
+  - Methods:
+    - `signUp(email, password)` - Email registration
+    - `signIn(email, password)` - Email login
+    - `signInWithOAuth(provider)` - OAuth providers (google, github)
+    - `signOut()` - Sign out and session cleanup
+  - Session management: Automatic via `onAuthStateChange` listener
+  - State storage: React hooks (session, user, loading states)
+
+## Monitoring & Observability
+
+**Error Tracking:**
+- Not detected
+
+**Logs:**
+- Browser console logging only
+- Error propagation via toast notifications (Sonner library)
+
+## CI/CD & Deployment
+
+**Hosting:**
+- Not detected (SPA intended for static hosting)
+
+**CI Pipeline:**
+- Not detected
+
+## Environment Configuration
+
+**Required env vars:**
+- `VITE_SUPABASE_URL` - Supabase project URL
+- `VITE_SUPABASE_ANON_KEY` - Supabase anonymous/public key
+- Both are validated at client initialization in `src/lib/supabase.ts`
+- Missing values throw error: "Missing VITE_SUPABASE_URL or VITE_SUPABASE_ANON_KEY env vars"
+
+**Secrets location:**
+- `.env` file (local, not committed)
+- Example template: `.env.example` (with placeholder values)
+
+## Webhooks & Callbacks
+
+**Incoming:**
+- Supabase OAuth redirect callbacks (Google, GitHub)
+- Handled by Supabase SDK automatically
+
+**Outgoing:**
+- Not detected
+
+## API Client Hooks
+
+**Data Fetching:**
+- `src/hooks/useAuth.ts` - Authentication state and session management
+- `src/hooks/useCategories.ts` - Category CRUD operations via React Query
+- `src/hooks/useTemplate.ts` - Template CRUD operations via React Query
+- `src/hooks/useBudgets.ts` - Budget CRUD operations with detail view support
+- `src/hooks/useQuickAdd.ts` - Quick add items management via React Query
+
+All hooks use TanStack React Query for:
+- Server state management
+- Automatic caching
+- Background refetching
+- Mutation handling (create, update, delete)
+- Query client invalidation for consistency
+
+## Database Access Pattern
+
+**Row Level Security:**
+- All tables use RLS policies to restrict access to authenticated users
+- Users can only read/write their own data via `auth.uid()` checks
+- Policies enforced at database level for security
+
+**Data Relationships:**
+- `profiles` (user data) ← extends `auth.users`
+- `categories` (user expense categories)
+- `templates` (saved expense templates)
+- `budgets` (budget tracking with items)
+- `quick_add` (quick transaction presets)

+
+**`src/components/`:**
+- Purpose: Reusable UI components and layout wrappers
+- Contains: Custom components + UI library primitives
+- Key files:
+  - `AppLayout.tsx` - Sidebar wrapper for authenticated pages

+- Returns { data, loading, ...mutations }
+- Implements onSuccess cache invalidation
+
+**`src/lib/`:**
+- Purpose: Core utilities, types, and configuration
+- Contains: 5 files

+
+**Testing:**
+- No test files present (no `*.test.ts`, `*.spec.ts`)
+- No jest.config.js or vitest.config.ts
+
+## Naming Conventions
+
+**Files:**
+- Pages: PascalCase with "Page" suffix (`DashboardPage.tsx`)
+- Hooks: camelCase with "use" prefix (`useAuth.ts`, `useBudgets.ts`)
+- Components: PascalCase (`AppLayout.tsx`, `QuickAddPicker.tsx`)
+- Utilities: camelCase descriptive (`format.ts`, `palette.ts`)
+- Types: camelCase file, PascalCase exports (`types.ts` exports `interface Budget`)
+- UI components: kebab-case file, PascalCase export (`card.tsx` exports `Card`)
+
+**Directories:**
+- Feature folders: lowercase plural (`src/hooks/`, `src/pages/`, `src/components/`)
+- UI library: `ui/` subfolder under components
+
+**Functions & Variables:**
+- Functions: camelCase (`formatCurrency`, `useBudgets`)
+- Component functions: PascalCase (`DashboardPage`, `QuickAddPicker`)
+- Constants: UPPER_SNAKE_CASE (`CATEGORY_TYPES`, `EXPENSE_TYPES`)
+- Variables: camelCase (`budgetId`, `categoryId`, `isSaving`)
+
+**Types:**
+- Interfaces: PascalCase (`Budget`, `BudgetItem`)
+- Type unions: PascalCase (`CategoryType`)
+- Props interfaces: PascalCase ending with "Props" (`QuickAddPickerProps`)
+
+## Where to Add New Code
+
+**New Feature (e.g., Reports):**
+1. Create page: `src/pages/ReportsPage.tsx`
+2. Create hook: `src/hooks/useReports.ts` with query keys and mutations
+3. Add types: `src/lib/types.ts` - add new interfaces (Report, ReportItem)
+4. Add route: `src/App.tsx` - add Route element
+5. Add nav link: `src/components/AppLayout.tsx` - add to navItems array
+6. Add i18n: `src/i18n/en.json` and `src/i18n/de.json` - add new keys
+
+**New Component (e.g., CategoryBadge):**
+- If simple display component: `src/components/CategoryBadge.tsx`
+- If UI primitive wrapper: `src/components/ui/category-badge.tsx` (follow shadcn pattern)
+- Composition: Import from ui/ folder, layer styling via className
+
+**New Utility Function:**
+- General helpers: `src/lib/utils.ts`
+- Domain-specific (e.g., budget math): Add to relevant hook file or create `src/lib/budgetHelpers.ts`
+- Formatting logic: `src/lib/format.ts`
+
+**New Hook:**
+- Data fetching: `src/hooks/useFeatureName.ts`
+- Pattern: Export named function, define query keys, use useQuery/useMutation, return typed object
+- Example structure from `useTemplate.ts`:
+  - Query keys at top (const)
+  - Helper functions (async functions)
+  - Main hook function with useQuery/useMutation setup
+  - Exposed API object return
+
+**Styling:**
+- Component styles: Tailwind className in JSX (no CSS files)
+- Global styles: `src/index.css` (imports Tailwind directives)
+- Color system: CSS variables in theme (Tailwind config)
+- Category colors: `src/lib/palette.ts` (maps to CSS var(--color-X))
+
+## Special Directories
+
+**`src/components/ui/`:**
+- Purpose: Shadcn registry of unstyled, accessible Radix UI components
+- Generated: Via `npx shadcn-ui@latest add [component]`
+- Committed: Yes (production code)
+- Do NOT hand-edit — regenerate if Shadcn updates
+
+**`public/`:**
+- Purpose: Static assets (favicon, images, fonts)
+- Generated: No
+- Committed: Yes
+- Served at root by Vite
+
+**`supabase/migrations/`:**
+- Purpose: Database schema as versioned SQL files
+- Generated: Via Supabase CLI
+- Committed: Yes (tracked via git)
+- Applied: By `supabase db push` command
+
+**`.env` files:**
+- Purpose: Runtime configuration (Supabase URL, API key)
+- Generated: Via `.env.example` template
+- Committed: NO — in .gitignore
+- Required for: Local dev and CI/CD
+
+**`dist/`:**
+- Purpose: Production bundle output
+- Generated: Via `npm run build`
+- Committed: No — in .gitignore
+- Deployment: Upload contents to CDN or web server
+
+## Code Organization Principles
+
+**Vertical Slices:**
+- Feature → Page → Hook → Library
+- Minimizes cross-feature coupling
+- Easy to add/remove features
+
+**Co-location of Related Code:**
+- Page component near its hooks
+- Query keys defined in same hook as queries
+- Mutations and queries in same hook for domain entity
+
+**Type Safety:**
+- All Supabase queries cast return value to TypeScript type
+- TanStack Query generic parameters: `useQuery<Type>()` and `useMutation<Payload, Response>()`
+- Props interfaces for all custom components
+
+**Consistent Hook Patterns:**
+- All data hooks follow: query setup → mutations setup → return typed object
+- Mutations always have onSuccess cache invalidation
+- Query keys are hierarchical arrays enabling granular invalidation

+# Testing Patterns
+
+**Analysis Date:** 2026-03-16
+
+## Test Framework
+
+**Runner:**
+- Not configured - No test framework installed
+- No test files in `src/` directory
+- No testing scripts in `package.json`
+- No `vitest.config.ts`, `jest.config.ts`, or similar configuration
+
+**Assertion Library:**
+- Not installed - No testing framework active
+
+**Run Commands:**
+- No test commands available
+- `npm run dev` - Development server
+- `npm run build` - Production build
+- `npm run lint` - ESLint only
+- `npm run preview` - Preview built assets
+
+**Status:** Testing infrastructure not yet implemented.
+
+## Test File Organization
+
+**Location:**
+- Not applicable - no test files exist
+- Suggested pattern: Co-located tests
+- Recommendation: Place `ComponentName.test.tsx` alongside `ComponentName.tsx`
+- Recommendation: Place `hookName.test.ts` alongside `hookName.ts`
+
+**Naming:**
+- `.test.ts` or `.test.tsx` suffix preferred for consistency with industry standard
+
+**Structure:**
+- Suggested directory pattern:
+```
+src/
+├── components/
+│   ├── QuickAddPicker.tsx
+│   ├── QuickAddPicker.test.tsx
+│   └── ui/
+│       ├── button.tsx
+│       └── button.test.tsx
+├── hooks/
+│   ├── useAuth.ts
+│   ├── useAuth.test.ts
+│   └── ...
+└── lib/
+    ├── utils.ts
+    ├── utils.test.ts
+    └── ...
+```
+
+## Test Structure
+
+**Suite Organization:**
+- Not yet implemented
+- Recommended framework: Vitest (lightweight, modern, TypeScript-first)
+- Example pattern to implement:
+```typescript
+import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest'
+import { useAuth } from '@/hooks/useAuth'
+
+describe('useAuth', () => {
+  beforeEach(() => {
+    // Setup
+  })
+
+  afterEach(() => {
+    // Cleanup
+  })
+
+  it('should load session on mount', () => {
+    // Test implementation
+  })
+})
+```
+
+**Patterns to establish:**
+- One top-level `describe` per hook/component
+- Nested `describe` blocks for related test groups
+- Each test file focuses on single module
+- Use of `beforeEach` for setup, `afterEach` for cleanup
+
+## Mocking
+
+**Framework:**
+- Not yet configured
+- Recommended: Vitest with `vi` module for mocking
+- Alternative: Mock Service Worker (MSW) for API mocking
+
+**Patterns to implement:**
+
+**Supabase Client Mocking:**
+```typescript
+vi.mock('@/lib/supabase', () => ({
+  supabase: {
+    auth: {
+      getSession: vi.fn(),
+      getUser: vi.fn(),
+      onAuthStateChange: vi.fn(),
+      signUp: vi.fn(),
+      signIn: vi.fn(),
+      signOut: vi.fn(),
+    },
+    from: vi.fn(),
+  },
+}))
+```
+
+**React Query Mocking:**
+```typescript
+vi.mock('@tanstack/react-query', () => ({
+  useQuery: vi.fn(),
+  useMutation: vi.fn(),
+  useQueryClient: vi.fn(),
+}))
+```
+
+**What to Mock:**
+- External API calls (Supabase queries/mutations)
+- React Query hooks (`useQuery`, `useMutation`)
+- Toast notifications (`sonner`)
+- Browser APIs (window, localStorage when needed)
+- i18next translation function
+
+**What NOT to Mock:**
+- Internal hook logic
+- Component rendering
+- State management patterns
+- User interaction handlers (test actual behavior)
+
+## Fixtures and Factories
+
+**Test Data:**
+- Not yet established
+- Recommended location: `src/__tests__/fixtures/` or `src/__tests__/factories/`
+
+**Recommended pattern:**
+```typescript
+// src/__tests__/factories/category.factory.ts
+import type { Category } from '@/lib/types'
+
+export function createCategory(overrides?: Partial<Category>): Category {
+  return {
+    id: crypto.randomUUID(),
+    user_id: 'test-user-id',
+    name: 'Test Category',
+    type: 'bill',
+    icon: null,
+    sort_order: 0,
+    created_at: new Date().toISOString(),
+    updated_at: new Date().toISOString(),
+    ...overrides,
+  }
+}
+```
+
+**Location:**
+- Suggested: `src/__tests__/factories/` for factory functions
+- Suggested: `src/__tests__/fixtures/` for static test data
+- Alternative: Inline factories in test files for simple cases
+
+## Coverage
+
+**Requirements:**
+- Not enforced - No coverage configuration
+- Recommended minimum: 70% for new code
+- Critical paths: hooks and mutation handlers (highest priority)
+
+**View Coverage:**
+- Once test framework installed, run:
+```bash
+npm run test:coverage
+```
+
+**Recommended coverage config (vitest.config.ts):**
+```typescript
+export default defineConfig({
+  test: {
+    coverage: {
+      provider: 'v8',
+      reporter: ['text', 'html', 'json'],
+      exclude: [
+        'node_modules/',
+        'src/__tests__/',
+      ],
+    },
+  },
+})
+```
+
+## Test Types
+
+**Unit Tests:**
+- Scope: Individual functions, hooks, components in isolation
+- Approach: Test pure logic without external dependencies
+- Priority: Utility functions (`cn()`, `formatCurrency()`), custom hooks
+- Example targets:
+  - `useBudgets()` query/mutation logic
+  - `useAuth()` session management
+  - `formatCurrency()` number formatting
+  - Validation logic in components
+
+**Integration Tests:**
+- Scope: Multiple modules working together (e.g., hook + component)
+- Approach: Mock Supabase, test hook + component interaction
+- Priority: Complex components like `QuickAddPicker` with multiple state changes
+- Example: Component flow - open popover → select item → open dialog → save
+
+**E2E Tests:**
+- Framework: Not used
+- Recommended: Playwright or Cypress for future implementation
+- Focus areas: Full user workflows (login → create budget → add items)
+
+## Common Patterns
+
+**Async Testing:**
+- Recommended approach with Vitest:
+```typescript
+it('should fetch categories', async () => {
+  const { result } = renderHook(() => useCategories())
+
+  await waitFor(() => {
+    expect(result.current.categories).toHaveLength(1)
+  })
+})
+```
+
+- Alternative with MSW:
+```typescript
+it('should handle API error', async () => {
+  server.use(
+    http.get('/api/categories', () => {
+      return HttpResponse.error()
+    })
+  )
+
+  const { result } = renderHook(() => useCategories())
+
+  await waitFor(() => {
+    expect(result.current.loading).toBe(false)
+  })
+})
+```
+
+**Error Testing:**
+- Test error states and error handling:
+```typescript
+it('should throw on auth error', async () => {
+  const mockSupabase = vi.mocked(supabase)
+  mockSupabase.auth.signIn.mockRejectedValueOnce(
+    new Error('Invalid credentials')
+  )
+
+  const { result } = renderHook(() => useAuth())
+
+  await expect(result.current.signIn('test@test.com', 'wrong')).rejects.toThrow()
+})
+```
+
+- Test error UI display:
+```typescript
+it('should display error message on login failure', async () => {
+  render(<LoginPage />)
+
+  const input = screen.getByRole('textbox', { name: /email/i })
+  await userEvent.type(input, 'test@test.com')
+
+  await userEvent.click(screen.getByRole('button', { name: /sign in/i }))
+
+  await waitFor(() => {
+    expect(screen.getByText(/invalid credentials/i)).toBeInTheDocument()
+  })
+})
+```
+
+## React Testing Library Patterns
+
+**When to implement:**
+- Recommended alongside unit tests for components
+- Use `@testing-library/react` for component testing
+- Use `@testing-library/user-event` for user interactions
+
+**Component test example structure:**
+```typescript
+import { render, screen, waitFor } from '@testing-library/react'
+import userEvent from '@testing-library/user-event'
+import QuickAddPicker from '@/components/QuickAddPicker'
+
+describe('QuickAddPicker', () => {
+  const mockBudgetId = 'test-budget-id'
+
+  it('should open popover on button click', async () => {
+    const user = userEvent.setup()
+    render(<QuickAddPicker budgetId={mockBudgetId} />)
+
+    const button = screen.getByRole('button', { name: /quick add/i })
+    await user.click(button)
+
+    expect(screen.getByRole('listbox')).toBeInTheDocument()
+  })
+})
+```
+
+## Setup and Configuration (Future)
+
+**Recommended `vitest.config.ts`:**
+```typescript
+import { defineConfig } from 'vitest/config'
+import react from '@vitejs/plugin-react'
+import path from 'path'
+
+export default defineConfig({
+  plugins: [react()],
+  test: {
+    globals: true,
+    environment: 'jsdom',
+    setupFiles: ['./src/__tests__/setup.ts'],
+    coverage: {
+      provider: 'v8',
+      reporter: ['text', 'html'],
+      include: ['src/**/*.{ts,tsx}'],
+      exclude: ['src/**/*.test.{ts,tsx}', 'src/**/*.d.ts'],
+    },
+  },
+  resolve: {
+    alias: {
+      '@': path.resolve(__dirname, './src'),
+    },
+  },
+})
+```
+
+**Recommended `src/__tests__/setup.ts`:**
+```typescript
+import { beforeAll, afterEach, afterAll, vi } from 'vitest'
+import { setupServer } from 'msw/node'
+import { expect, afterEach as vitestAfterEach } from 'vitest'
+
+// Mock MSW server setup (if using MSW)
+export const server = setupServer()
+
+beforeAll(() => {
+  server.listen({ onUnhandledRequest: 'error' })
+})
+
+afterEach(() => {
+  server.resetHandlers()
+})
+
+afterAll(() => {
+  server.close()
+})
+```
+
+**Package additions needed:**
+```json
+{
+  "devDependencies": {
+    "vitest": "^1.0.0",
+    "@testing-library/react": "^14.0.0",
+    "@testing-library/user-event": "^14.0.0",
+    "@testing-library/jest-dom": "^6.0.0",
+    "jsdom": "^23.0.0",
+    "msw": "^2.0.0"
+  }
+}
+```
+
+## Critical Test Priorities
+
+**High Priority (Core Functionality):**
+1. Hook mutations (`useBudgets.createBudget`, `useBudgets.generateFromTemplate`)
+2. Authentication flow (`useAuth.signIn`, `useAuth.signOut`)
+3. Complex component state (`QuickAddPicker` dialog flow)
+4. Validation logic (form field checks)
+
+**Medium Priority (Data Access):**
+1. Category queries and filtering
+2. Budget item CRUD operations
+3. Template copying logic
+4. Sorting and ordering
+
+**Lower Priority (UI/Display):**
+1. Component rendering
+2. Conditional displays
+3. Icon rendering
+4. Theme switching
+

+
+*Testing analysis: 2026-03-16*
+
+**Note:** No test framework currently installed. This document provides guidance for future test implementation. Recommend prioritizing Vitest as lightweight TypeScript-native test framework complementing Vite build tooling already in use.

+# Roadmap: SimpleFinanceDash UI/UX Overhaul
+
+## Overview
+
+This milestone transforms SimpleFinanceDash from a functional-but-basic budget app into a visually rich, cohesive personal finance dashboard. The overhaul is strictly UI-only — no backend or schema changes. Work flows from design foundations (tokens, shared components) through the dashboard (charts, collapsible sections) to full-app consistency across all 9 pages. The research phase is complete; all four phases use well-documented patterns and require no further research before planning.
+
+## Phases
+
+**Phase Numbering:**
+- Integer phases (1, 2, 3): Planned milestone work
+- Decimal phases (2.1, 2.2): Urgent insertions (marked with INSERTED)
+
+Decimal phases appear between their surrounding integers in numeric order.
+
+- [x] **Phase 1: Design Foundation and Primitives** - Install shadcn primitives, extend color tokens, build PageShell and StatCard/SummaryStrip
+- [x] **Phase 2: Dashboard Charts and Layout** - Build DashboardContent orchestrator with all three chart types and month navigation (completed 2026-03-16)
+- [x] **Phase 3: Collapsible Dashboard Sections** - Add CategorySection with Radix Collapsible, BudgetLineItems, and group totals (completed 2026-03-17)
+- [x] **Phase 4: Full-App Design Consistency** - Apply PageShell and established patterns to all 9 non-dashboard pages (completed 2026-03-17)
+
+## Phase Details
+
+### Phase 1: Design Foundation and Primitives
+**Goal**: Establish the design system building blocks — color tokens, shadcn primitives, and shared components — so all subsequent phases build on a consistent visual foundation
+**Depends on**: Nothing (first phase)
+**Requirements**: UI-DASH-01, UI-DESIGN-01, UI-RESPONSIVE-01
+**Research flag**: No — Tailwind v4 `@theme inline`, OKLCH tokens, and WCAG contrast requirements are well-documented
+**Success Criteria** (what must be TRUE):
+  1. Running `npx shadcn@latest add chart` and `npx shadcn@latest add collapsible` has installed both primitives, and `chart.tsx` has the `initialDimension` patch applied (no `width(-1)` console warnings when rendering a test chart)
+  2. `index.css` `@theme inline` block contains extended category color tokens with richer chroma and semantic status tokens (`--color-over-budget`, `--color-on-budget`), and all semantic color pairs pass WCAG 4.5:1 contrast for text
+  3. `PageShell` component renders a consistent page header with title, optional description, and CTA slot — and is importable from `components/shared/`
+  4. `StatCard` and `SummaryStrip` components render KPI cards (income, expenses, balance) with semantic color coding and variance badges — visible on the dashboard page
+  5. Skeleton loading components exist that mirror the real card and chart layout structure
+**Plans**: 2 plans
+
+Plans:
+- [x] 01-01-PLAN.md — Install shadcn primitives (chart + collapsible), extend OKLCH color tokens, add i18n keys
+- [x] 01-02-PLAN.md — Build PageShell, StatCard, SummaryStrip, DashboardSkeleton and integrate into DashboardPage
+
+### Phase 2: Dashboard Charts and Layout
+**Goal**: Deliver the full dashboard chart suite — donut, vertical bar, and horizontal bar — inside a responsive 3-column layout, with month navigation and memoized data derivations
+**Depends on**: Phase 1
+**Requirements**: UI-DASH-01, UI-BAR-01, UI-HBAR-01, UI-DONUT-01
+**Research flag**: No — Recharts 2.15.4 chart implementations and the `chart.tsx` fix are fully documented
+**Success Criteria** (what must be TRUE):
+  1. Dashboard displays an expense donut chart with center total label, active sector hover expansion, and a custom legend — replacing the existing flat pie chart
+  2. Dashboard displays a grouped vertical bar chart comparing income budgeted vs actual amounts
+  3. Dashboard displays a horizontal bar chart comparing budget vs actual spending by category type
+  4. All three charts consume colors from CSS variable tokens (no hardcoded hex values) and render correctly with zero-item budgets (empty state)
+  5. User can navigate between budget months on the dashboard without leaving the page, and all charts and cards update to reflect the selected month
+**Plans**: 3 plans
+
+Plans:
+- [x] 02-01-PLAN.md — Month navigation infrastructure (useMonthParam hook, MonthNavigator, ChartEmptyState, i18n keys)
+- [x] 02-02-PLAN.md — Three chart components (ExpenseDonutChart, IncomeBarChart, SpendBarChart)
+- [x] 02-03-PLAN.md — Dashboard integration (wire charts + month nav into DashboardPage, update skeleton)
+
+### Phase 3: Collapsible Dashboard Sections
+**Goal**: Complete the dashboard hybrid view with collapsible per-category sections that show individual line items, group totals, and variance indicators
+**Depends on**: Phase 2
+**Requirements**: UI-DASH-01, UI-COLLAPSE-01
+**Research flag**: No — Radix Collapsible API and animation pattern are well-documented
+**Success Criteria** (what must be TRUE):
+  1. Each category group (income, bills, variable expenses, debt, savings, investment) renders as a collapsible section with a color-accented header showing the group label, budgeted total, actual total, and difference
+  2. Expanding a section reveals a line-item table with individual budget items, and collapsing it hides the table with a smooth CSS animation (no layout shift in charts above)
+  3. Toggling sections rapidly does not produce `ResizeObserver loop` console errors or visible chart resize jank
+  4. Carryover amount is visible on the dashboard balance card when the budget has a non-zero carryover
+**Plans**: 2 plans
+
+Plans:
+- [x] 03-01-PLAN.md — Build carryover display, CSS animation tokens, i18n keys, CategorySection and CollapsibleSections components
+- [x] 03-02-PLAN.md — Wire collapsible sections into DashboardContent with smart defaults, update skeleton, verify
+
+### Phase 4: Full-App Design Consistency
+**Goal**: Apply the design system established in Phases 1-3 to every page in the app, delivering a consistent visual experience across all navigation paths
+**Depends on**: Phase 3
+**Requirements**: UI-DESIGN-01, UI-AUTH-01, UI-CATEGORIES-01, UI-TEMPLATE-01, UI-BUDGETS-01, UI-QUICKADD-01, UI-SETTINGS-01, UI-RESPONSIVE-01
+**Research flag**: No — PageShell application and page-by-page refresh are repetitive pattern application
+**Success Criteria** (what must be TRUE):
+  1. All 9 pages (Login, Register, Categories, Template, Budget List, Budget Detail, Quick Add, Settings, Dashboard) use `PageShell` for their header and share the same typography, card style, and color token usage
+  2. Login and Register pages have a refreshed visual design with the same card and color patterns as the dashboard
+  3. Budget Detail page displays category groups with the same color-accented card style and line-item presentation as the dashboard collapsible sections
+  4. Navigating between any two pages in the app produces no jarring visual discontinuity in layout, color, or typography
+  5. Switching the app to German locale shows fully translated text on every page — no raw i18n key strings visible anywhere
+**Plans**: 3 plans
+
+Plans:
+- [x] 04-01-PLAN.md — Redesign auth pages (Login, Register) with brand presence, muted background, card accent, OAuth SVG icons
+- [x] 04-02-PLAN.md — Upgrade CRUD pages (Categories, Template, QuickAdd, Settings) with PageShell, skeletons, group header accents
+- [x] 04-03-PLAN.md — Upgrade budget pages (BudgetList, BudgetDetail) with semantic tokens, direction-aware diff, locale-aware months, skeletons

+<objective>
+Install shadcn UI primitives (chart, collapsible), apply the Recharts v3 compatibility patch, extend the OKLCH color token system with richer chroma and semantic status tokens, and add new i18n keys for the dashboard redesign.
+
+Purpose: Establish the lowest-level design system building blocks that Plan 02 components and all subsequent phases depend on. Without tokens and primitives, no component can reference semantic colors or chart wrappers.
+
+Output: Patched chart.tsx, collapsible.tsx, extended index.css tokens, and parity-checked i18n keys in both languages.

+  <action>
+1. Run `npx shadcn@latest add chart` to generate `src/components/ui/chart.tsx`. This installs the ChartContainer, ChartTooltip, and ChartTooltipContent wrappers around Recharts.
+
+2. Open the generated `src/components/ui/chart.tsx` and find the `ResponsiveContainer` element inside the `ChartContainer` component. Add the `initialDimension` prop to fix the Recharts v3 compatibility issue (shadcn-ui/ui#9892):
+
+   BEFORE:
+   ```tsx
+   <RechartsPrimitive.ResponsiveContainer>
+   ```
+   AFTER:
+   ```tsx
+   <RechartsPrimitive.ResponsiveContainer
+     initialDimension={{ width: 320, height: 200 }}
+   >
+   ```
+
+   NOTE: If the generated file ALREADY contains `initialDimension` (meaning PR #8486 has merged), skip the manual patch.
+
+3. Run `npx shadcn@latest add collapsible` to generate `src/components/ui/collapsible.tsx`. No post-install patch needed.
+
+4. Verify both files are importable by confirming `npm run build` passes.
+
+IMPORTANT: Do NOT install any npm packages manually. The shadcn CLI generates component files from the existing `radix-ui` and `recharts` packages already in package.json.

+  <name>Task 2: Extend color tokens and add i18n keys</name>
+  <files>src/index.css, src/i18n/en.json, src/i18n/de.json</files>
+  <action>
+**Part A: Extend color tokens in index.css**
+
+Open `src/index.css` and modify the `@theme inline` block. Keep ALL existing tokens unchanged. Add the following new tokens AFTER the existing `--color-chart-5` line and BEFORE `--radius`:
+
+1. Semantic status tokens (for budget comparison display):
+   ```css
+   /* Semantic Status Tokens */
+   --color-over-budget:   oklch(0.55 0.20 25);
+   --color-on-budget:     oklch(0.50 0.17 155);
+   --color-budget-bar-bg: oklch(0.92 0.01 260);
+   ```
+
+2. Chart fill variants (lighter versions of category colors for non-text chart fills at 3:1 minimum contrast):
+   ```css
+   /* Chart Fill Variants */
+   --color-income-fill:           oklch(0.68 0.19 155);
+   --color-bill-fill:             oklch(0.65 0.19 25);
+   --color-variable-expense-fill: oklch(0.70 0.18 50);
+   --color-debt-fill:             oklch(0.60 0.20 355);
+   --color-saving-fill:           oklch(0.68 0.18 220);
+   --color-investment-fill:       oklch(0.65 0.18 285);
+   ```
+
+3. Update the existing 6 category color tokens to darker values for WCAG 4.5:1 text contrast against white (--color-card = oklch(1 0 0)):
+   ```css
+   --color-income:           oklch(0.55 0.17 155);
+   --color-bill:             oklch(0.55 0.17 25);
+   --color-variable-expense: oklch(0.58 0.16 50);
+   --color-debt:             oklch(0.52 0.18 355);
+   --color-saving:           oklch(0.55 0.16 220);
+   --color-investment:       oklch(0.55 0.16 285);
+   ```
+
+Do NOT modify any other existing tokens (background, foreground, primary, secondary, muted, accent, destructive, border, input, ring, sidebar-*). Do NOT modify the chart-1 through chart-5 tokens (they are used by shadcn chart config and will be updated separately in Phase 2 if needed).
+
+**Part B: Add i18n keys to en.json**
+
+Add the following keys to the `"dashboard"` section in `src/i18n/en.json`. Merge with existing keys (do not overwrite existing ones like "title", "totalIncome", "totalExpenses", "availableBalance", "expenseBreakdown", "noBudget"):
+
+```json
+"dashboard": {
+  "title": "Dashboard",
+  "totalIncome": "Total Income",
+  "totalExpenses": "Total Expenses",
+  "netBalance": "Net Balance",
+  "availableBalance": "Available Balance",

+  "overBudget": "over budget",
+  "underBudget": "under budget",
+  "onTrack": "On track",
+  "loading": "Loading dashboard..."
+}
+```
+
+New keys being added: "carryover", "vsBudget", "overBudget", "underBudget", "onTrack", "loading".
+
+**Part C: Add matching German i18n keys to de.json**
+
+Add the same new keys to the `"dashboard"` section in `src/i18n/de.json`:
+
+```json
+"dashboard": {
+  "title": "Dashboard",
+  "totalIncome": "Gesamteinkommen",
+  "totalExpenses": "Gesamtausgaben",
+  "netBalance": "Nettobilanz",
+  "availableBalance": "Verfügbares Guthaben",

+  "overBudget": "über Budget",
+  "underBudget": "unter Budget",
+  "onTrack": "Im Plan",
+  "loading": "Dashboard wird geladen..."
+}
+```
+
+IMPORTANT: Both language files MUST be updated in the same commit. Verify key count parity: en.json and de.json should have the same number of total keys after changes.

+# Phase 1 Plan 1: Design Primitives Summary
+
+**shadcn chart/collapsible primitives with Recharts v3 patch, two-tier OKLCH category colors, semantic budget status tokens, and bilingual dashboard i18n keys**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-16T11:12:04Z
+- **Completed:** 2026-03-16T11:14:52Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- Installed shadcn chart and collapsible UI primitives with Recharts v3 initialDimension compatibility patch
+- Extended OKLCH color token system with two-tier category colors (dark text + lighter fills) and 3 semantic budget status tokens
+- Added 6 new dashboard i18n keys to both en.json and de.json at full parity
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Install shadcn primitives and patch chart.tsx** - `d89d70f` (feat)
+2. **Task 2: Extend color tokens and add i18n keys** - `4f74c79` (feat)
+
+## Files Created/Modified
+- `src/components/ui/chart.tsx` - ChartContainer, ChartTooltip, ChartTooltipContent wrappers with initialDimension patch
+- `src/components/ui/collapsible.tsx` - Collapsible, CollapsibleTrigger, CollapsibleContent radix primitives
+- `src/index.css` - Extended @theme inline block with semantic status tokens, chart fill variants, darkened category text colors
+- `src/i18n/en.json` - 6 new dashboard keys (carryover, vsBudget, overBudget, underBudget, onTrack, loading)
+- `src/i18n/de.json` - Matching 6 German dashboard keys at parity
+
+## Decisions Made
+- Applied initialDimension={{ width: 320, height: 200 }} patch since shadcn CLI still generates without it (PR #8486 not yet merged)
+- Category text colors darkened to ~0.55 lightness for WCAG 4.5:1 contrast against white card background
+- Chart fill variants kept lighter at ~0.65-0.70 for non-text use with 3:1 minimum contrast
+- Investment hue adjusted from 290 to 285 for better OKLCH gamut representation
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+- Pre-existing lint errors found in badge.tsx, button.tsx, sidebar.tsx, and useBudgets.ts (5 errors total). These are not caused by this plan's changes and have been logged to deferred-items.md. Build passes; lint failures are in unmodified files only.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Chart and collapsible primitives ready for Plan 02 component composition
+- Color tokens and i18n keys available for all subsequent dashboard UI work
+- No blockers for Plan 02 execution
+
+## Self-Check: PASSED
+
+All 5 created/modified files verified present. Both task commits (d89d70f, 4f74c79) verified in git log.

+<objective>
+Build the shared components (PageShell, StatCard, SummaryStrip, DashboardSkeleton) and integrate them into DashboardPage, replacing the inline SummaryCard, null loading state, and hardcoded color classes.
+
+Purpose: Deliver the visual foundation components that all subsequent phases consume. After this plan, the dashboard has semantic KPI cards with variance badges, skeleton loading, and a consistent page header pattern ready for reuse across all 9 pages.
+
+Output: 4 new component files, refactored DashboardPage.tsx.

+interface PageShellProps {
+  title: string
+  description?: string
+  action?: React.ReactNode
+  children: React.ReactNode
+}
+
+export function PageShell({ title, description, action, children }: PageShellProps) {

+      </div>
+      {children}
+    </div>
+  )
+}
+```
+
+Key decisions:
+- Named export (not default) per convention for shared components
+- `text-2xl font-semibold tracking-tight` matches existing DashboardPage heading
+- `action` is a ReactNode slot, not a button-specific prop
+- No padding baked in -- AppLayout.tsx already provides `p-6`
+- No i18n dependency -- title comes from the caller via `t()` at the page level
+
+**File 2: src/components/dashboard/StatCard.tsx**
+
+Follow the pattern from research (Pattern 2) exactly. Named export `StatCard`.
+
+Props interface:
+```typescript
+interface StatCardProps {
+  title: string
+  value: string
+  valueClassName?: string
+  variance?: {
+    amount: string
+    direction: "up" | "down" | "neutral"
+    label: string
+  }
+}
+```
+
+Implementation:
+- Import `Card`, `CardContent`, `CardHeader`, `CardTitle` from `@/components/ui/card`
+- Import `TrendingUp`, `TrendingDown`, `Minus` from `lucide-react`
+- Import `cn` from `@/lib/utils`
+- Use `text-2xl font-bold tabular-nums tracking-tight` for the value (upgraded from existing `font-semibold` for more visual weight)
+- Variance section renders a directional icon (size-3) + amount text + label in `text-xs text-muted-foreground`
+- Do NOT import Badge -- the variance display uses inline layout, not a badge component
+
+**File 3: src/components/dashboard/SummaryStrip.tsx**
+
+Follow the pattern from research (Pattern 3). Named export `SummaryStrip`.
+
+Props interface:
+```typescript
+interface SummaryStripProps {
+  income: { value: string; budgeted: string }
+  expenses: { value: string; budgeted: string }
+  balance: { value: string; isPositive: boolean }
+  t: (key: string) => string
+}
+```
+
+Implementation:
+- Import `StatCard` from `./StatCard`
+- Renders a `<div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">` with 3 StatCards
+- Income card: `title={t("dashboard.totalIncome")}`, `valueClassName="text-income"`, variance with direction "neutral" and label `t("budgets.budgeted")`
+- Expenses card: `title={t("dashboard.totalExpenses")}`, `valueClassName="text-destructive"`, variance with direction "neutral" and label `t("budgets.budgeted")`
+- Balance card: `title={t("dashboard.availableBalance")}`, `valueClassName={balance.isPositive ? "text-on-budget" : "text-over-budget"}`, no variance prop
+
+Note: The `t` function is passed as a prop to keep SummaryStrip as a presentational component that does not call `useTranslation()` internally. The parent (DashboardContent) already has `t` from `useTranslation()`.
+
+**File 4: src/components/dashboard/DashboardSkeleton.tsx**
+
+Follow the pattern from research (Pattern 4). Named export `DashboardSkeleton`.
+
+Implementation:
+- Import `Skeleton` from `@/components/ui/skeleton`
+- Import `Card`, `CardContent`, `CardHeader` from `@/components/ui/card`
+- Renders a `<div className="flex flex-col gap-6">` with:
+  1. Summary cards skeleton: `<div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">` with 3 skeleton cards matching StatCard layout (Skeleton h-4 w-24 for title, Skeleton h-8 w-32 for value, Skeleton h-3 w-20 for variance)
+  2. Chart area skeleton: `<div className="grid gap-6 lg:grid-cols-2">` with 2 skeleton cards (Skeleton h-5 w-40 for chart title, Skeleton h-[240px] w-full rounded-md for chart area)
+
+This mirrors the real dashboard grid exactly so there is no layout shift when data loads.

+
+<task type="auto">
+  <name>Task 2: Integrate new components into DashboardPage</name>
+  <files>src/pages/DashboardPage.tsx</files>
+  <action>
+Refactor `src/pages/DashboardPage.tsx` to use the new shared components. This is a MODIFY operation -- preserve all existing logic (derived totals, pie chart, progress groups) while replacing the presentation layer.
+
+**Changes to make:**
+
+1. **Remove the inline SummaryCard component** (lines 45-66). Delete the entire `SummaryCardProps` interface and `SummaryCard` function. These are replaced by `StatCard`/`SummaryStrip`.
+
+2. **Add new imports** at the appropriate positions in the import order:
+   ```typescript
+   import { PageShell } from "@/components/shared/PageShell"
+   import { SummaryStrip } from "@/components/dashboard/SummaryStrip"
+   import { DashboardSkeleton } from "@/components/dashboard/DashboardSkeleton"
+   ```
+
+3. **Replace loading states with DashboardSkeleton:**
+   - In `DashboardContent`: Replace `if (loading) return null` (line 76) with `if (loading) return <DashboardSkeleton />`
+   - In `DashboardPage`: Replace `if (loading) return null` (line 291) with:
+     ```tsx
+     if (loading) return (
+       <PageShell title={t("dashboard.title")}>
+         <DashboardSkeleton />
+       </PageShell>
+     )
+     ```
+
+4. **Replace hardcoded balance color** (lines 95-98):
+   - BEFORE: `const balanceColor = availableBalance >= 0 ? "text-green-600 dark:text-green-400" : "text-red-600 dark:text-red-400"`
+   - AFTER: `const balanceColor = availableBalance >= 0 ? "text-on-budget" : "text-over-budget"`
+
+5. **Replace hardcoded progress bar colors** (lines 219-221):
+   - BEFORE: `const barColor = group.overBudget ? "bg-red-500 dark:bg-red-400" : "bg-green-500 dark:bg-green-400"`
+   - AFTER: `const barColor = group.overBudget ? "bg-over-budget" : "bg-on-budget"`
+
+6. **Replace hardcoded progress text color** (lines 235-239):
+   - BEFORE: `group.overBudget ? "text-red-600 dark:text-red-400" : "text-muted-foreground"`
+   - AFTER: `group.overBudget ? "text-over-budget" : "text-muted-foreground"`
+
+7. **Replace inline summary cards with SummaryStrip** in DashboardContent's return JSX. Replace the `<div className="grid gap-4 sm:grid-cols-3">` block (lines 135-149) with:
+   ```tsx
+   <SummaryStrip
+     income={{
+       value: formatCurrency(totalIncome, currency),
+       budgeted: formatCurrency(
+         items.filter((i) => i.category?.type === "income").reduce((sum, i) => sum + i.budgeted_amount, 0),
+         currency
+       ),
+     }}
+     expenses={{
+       value: formatCurrency(totalExpenses, currency),
+       budgeted: formatCurrency(
+         items.filter((i) => i.category?.type !== "income").reduce((sum, i) => sum + i.budgeted_amount, 0),
+         currency
+       ),
+     }}
+     balance={{
+       value: formatCurrency(availableBalance, currency),
+       isPositive: availableBalance >= 0,
+     }}
+     t={t}
+   />
+   ```
+
+   To avoid recomputing budgeted totals inline, derive them alongside the existing totalIncome/totalExpenses calculations:
+   ```typescript
+   const budgetedIncome = items
+     .filter((i) => i.category?.type === "income")
+     .reduce((sum, i) => sum + i.budgeted_amount, 0)
+
+   const budgetedExpenses = items
+     .filter((i) => i.category?.type !== "income")
+     .reduce((sum, i) => sum + i.budgeted_amount, 0)
+   ```
+
+8. **Replace the page header with PageShell** in the `DashboardPage` component's return. Replace:
+   ```tsx
+   <div>
+     <div className="mb-6 flex items-center justify-between">
+       <h1 className="text-2xl font-semibold">{t("dashboard.title")}</h1>
+     </div>
+     {/* content */}
+   </div>
+   ```
+   With:
+   ```tsx
+   <PageShell title={t("dashboard.title")}>
+     {/* content */}
+   </PageShell>
+   ```
+
+**What to preserve:**
+- All imports for Recharts (PieChart, Pie, Cell, ResponsiveContainer, Tooltip)
+- The `EXPENSE_TYPES` constant
+- The `currentMonthStart` helper
+- The `DashboardContent` component structure (budgetId prop, hooks, derived totals, pie chart, progress groups)
+- The `QuickAddPicker` usage
+- The entire pie chart + legend section
+- The entire category progress section (but with updated color classes)
+- The no-budget empty state with Link to /budgets
+
+**What to remove:**
+- The `SummaryCardProps` interface and `SummaryCard` function component
+- The hardcoded `text-green-600`, `text-red-600`, `bg-red-500`, `bg-green-500` color classes
+- The `if (loading) return null` patterns (both in DashboardContent and DashboardPage)
+- The inline `<div className="mb-6 flex items-center justify-between">` header
+  </action>
+  <verify>
+    <automated>npm run build && npm run lint</automated>
+  </verify>
+  <done>DashboardPage imports and uses PageShell, SummaryStrip, and DashboardSkeleton. No more inline SummaryCard component. Loading states show skeleton instead of null.

+# Phase 1 Plan 2: Dashboard Shared Components Summary
+
+**PageShell, StatCard, SummaryStrip, and DashboardSkeleton components with semantic OKLCH color tokens replacing all hardcoded green/red values in DashboardPage**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-16T11:17:50Z
+- **Completed:** 2026-03-16T11:20:38Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- Created 4 new shared components (PageShell, StatCard, SummaryStrip, DashboardSkeleton) establishing reusable patterns for all 9 pages
+- Refactored DashboardPage to use shared components, eliminating inline SummaryCard and null loading states
+- Replaced all hardcoded green/red color classes with semantic OKLCH tokens (text-on-budget, text-over-budget, bg-on-budget, bg-over-budget)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create PageShell, StatCard, SummaryStrip, and DashboardSkeleton** - `ffc5c5f` (feat)
+2. **Task 2: Integrate new components into DashboardPage** - `a533e06` (feat)
+
+## Files Created/Modified
+- `src/components/shared/PageShell.tsx` - Reusable page header wrapper with title, description, and action slot
+- `src/components/dashboard/StatCard.tsx` - KPI display card with formatted value, semantic color, and optional variance badge with directional icon
+- `src/components/dashboard/SummaryStrip.tsx` - Responsive 3-card grid (1/2/3 cols by breakpoint) composing StatCards for income, expenses, and balance
+- `src/components/dashboard/DashboardSkeleton.tsx` - Pulse-animated loading placeholder mirroring summary grid and chart card layout
+- `src/pages/DashboardPage.tsx` - Refactored to use PageShell, SummaryStrip, DashboardSkeleton; removed inline SummaryCard; semantic color tokens throughout
+
+## Decisions Made
+- StatCard uses `font-bold` (upgraded from existing `font-semibold`) for stronger visual weight on KPI values
+- SummaryStrip receives `t` function as a prop rather than calling `useTranslation()` internally, keeping it as a pure presentational component
+- DashboardSkeleton mirrors the exact grid structure of the real dashboard (3-col summary row + 2-col chart row) to prevent layout shift on load
+- Variance badge uses inline icon+text layout (TrendingUp/TrendingDown/Minus icons) instead of Badge component for lighter visual treatment
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+- Pre-existing lint errors (5 total in badge.tsx, button.tsx, sidebar.tsx, useBudgets.ts) remain from before this plan. No new lint errors introduced. Build passes cleanly.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- PageShell pattern ready for all remaining pages (budgets, categories, template, settings, quick-add)
+- StatCard/SummaryStrip available for any page needing KPI displays
+- DashboardSkeleton pattern established for loading states across the app
+- All Phase 1 components complete; Phase 2 can begin dashboard-specific chart and detail work
+
+## Self-Check: PASSED
+
+All 5 created/modified files verified present. Both task commits (ffc5c5f, a533e06) verified in git log.

+# Phase 1: Design Foundation and Primitives - Research
+
+**Researched:** 2026-03-16
+**Domain:** Design system tokens (OKLCH/CSS variables), shadcn/ui primitives, shared React components
+**Confidence:** HIGH
+
+## Summary
+
+Phase 1 establishes the design system building blocks that every subsequent phase consumes. The work breaks into four domains: (1) installing shadcn/ui primitives (`chart` and `collapsible`) with the known Recharts v3 compatibility patch, (2) extending the existing OKLCH color token system in `index.css` with richer category chroma and semantic status tokens, (3) building two shared components (`PageShell` for consistent page headers and `StatCard`/`SummaryStrip` for KPI cards), and (4) creating skeleton loading components that mirror the final dashboard layout.
+
+The existing codebase already has a well-structured `@theme inline` block in `index.css` with six category colors and five chart colors, a `palette.ts` mapping those CSS variables to a TypeScript record, and a `formatCurrency` utility. The current `DashboardPage.tsx` contains a simple `SummaryCard` component and an unmemoized `DashboardContent` function that this phase will partially replace. The shadcn/ui `skeleton.tsx` primitive already exists in `components/ui/`.
+
+The highest-risk item is the `chart.tsx` Recharts v3 patch. The generated `chart.tsx` from `npx shadcn@latest add chart` requires adding `initialDimension={{ width: 320, height: 200 }}` to the `ResponsiveContainer` inside `ChartContainer`. Without this, all charts will produce `width(-1) and height(-1)` console warnings and may render at zero dimensions. The patch is documented in shadcn-ui/ui issue #9892 and is a one-line fix.
+
+**Primary recommendation:** Install primitives first, patch chart.tsx immediately, then extend tokens, then build shared components, then skeletons. This order ensures each layer is available before the next layer depends on it.
+
+<phase_requirements>
+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| UI-DASH-01 | Redesign dashboard with hybrid layout -- summary cards, charts, and collapsible category sections | This phase delivers the summary cards layer (StatCard/SummaryStrip) and installs the chart and collapsible primitives that Phase 2 and 3 will consume. The existing `SummaryCard` in DashboardPage.tsx is replaced with a richer `StatCard` component with semantic color coding and variance badges. |
+| UI-DESIGN-01 | Redesign all pages with rich, colorful visual style -- consistent design language | This phase delivers the design foundation: extended OKLCH color tokens with richer chroma (0.18+ vs current 0.14), semantic status tokens (`--color-over-budget`, `--color-on-budget`), and `PageShell` -- the shared component that enforces consistent page headers across all 9 pages. Without this phase, design drift (Pitfall 6) is guaranteed. |
+| UI-RESPONSIVE-01 | Desktop-first responsive layout across all pages | This phase sets the responsive grid patterns for summary cards (`grid-cols-1 sm:grid-cols-2 lg:grid-cols-3`) and establishes `PageShell` with responsive padding and header layout. All subsequent phases inherit these breakpoints. |

+| `chart` | `npx shadcn@latest add chart` | `ChartContainer`, `ChartTooltip`, `ChartTooltipContent` wrappers | **CRITICAL:** Patch `chart.tsx` -- add `initialDimension={{ width: 320, height: 200 }}` to `ResponsiveContainer` |
+| `collapsible` | `npx shadcn@latest add collapsible` | Radix `Collapsible` primitive for Phase 3 category sections | None -- install and verify import works |
+
+### What NOT to Add
+
+| Avoid | Why |
+|-------|-----|
+| `accordion` | Research initially suggested it, but `Collapsible` gives independent per-section state without fighting Accordion's root-state coordination. Use individual `Collapsible` per `CategorySection`. |
+| Framer Motion | CSS transitions via `transition-all duration-200` cover all needed animations. No bundle weight added. |
+| Any new npm package | Stack is locked. All additions are shadcn CLI-generated component files, not npm dependencies. |
+

+    de.json              # MODIFY -- add new dashboard keys (same commit)
+```
+
+### Pattern 1: PageShell -- Consistent Page Header
+
+**What:** A wrapper component that enforces consistent heading size, spacing, optional description, and CTA slot across all pages.
+**When to use:** Every page in the app wraps its top section in `PageShell`.
+
+```typescript
+// src/components/shared/PageShell.tsx
+interface PageShellProps {
+  title: string
+  description?: string
+  action?: React.ReactNode
+  children: React.ReactNode
+}
+
+export function PageShell({ title, description, action, children }: PageShellProps) {
+  return (
+    <div className="flex flex-col gap-6">
+      <div className="flex items-start justify-between gap-4">
+        <div>
+          <h1 className="text-2xl font-semibold tracking-tight">{title}</h1>
+          {description && (
+            <p className="mt-1 text-sm text-muted-foreground">{description}</p>
+          )}
+        </div>
+        {action && <div className="shrink-0">{action}</div>}
+      </div>
+      {children}
+    </div>
+  )
+}
+```
+
+**Key decisions:**
+- `text-2xl font-semibold tracking-tight` matches the existing `DashboardPage` heading style
+- `action` is a `ReactNode` slot, not a button-specific prop -- allows any CTA element
+- No `padding` baked in -- the `<main>` in `AppLayout.tsx` already applies `p-6`
+- The existing `DashboardPage` header (`<div className="mb-6 flex items-center justify-between">`) is replaced by `PageShell` usage
+
+### Pattern 2: StatCard -- KPI Display Unit
+
+**What:** A single KPI card that displays a label, large formatted value, semantic color coding, and an optional variance badge.
+**When to use:** Summary cards on the dashboard (income, expenses, balance). May also be used on BudgetDetailPage summary in Phase 4.
+
+```typescript
+// src/components/dashboard/StatCard.tsx
+import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card"
+import { Badge } from "@/components/ui/badge"
+import { TrendingUp, TrendingDown, Minus } from "lucide-react"
+import { cn } from "@/lib/utils"
+
+interface StatCardProps {
+  title: string
+  value: string
+  valueClassName?: string
+  variance?: {
+    amount: string
+    direction: "up" | "down" | "neutral"
+    label: string
+  }
+}
+
+export function StatCard({ title, value, valueClassName, variance }: StatCardProps) {
+  return (
+    <Card>
+      <CardHeader className="pb-2">
+        <CardTitle className="text-sm font-medium text-muted-foreground">
+          {title}
+        </CardTitle>
+      </CardHeader>
+      <CardContent>
+        <p className={cn("text-2xl font-bold tabular-nums tracking-tight", valueClassName)}>
+          {value}
+        </p>
+        {variance && (
+          <div className="mt-1 flex items-center gap-1">
+            {variance.direction === "up" && <TrendingUp className="size-3" />}
+            {variance.direction === "down" && <TrendingDown className="size-3" />}
+            {variance.direction === "neutral" && <Minus className="size-3" />}
+            <span className="text-xs text-muted-foreground">
+              {variance.amount} {variance.label}
+            </span>
+          </div>
+        )}
+      </CardContent>
+    </Card>
+  )
+}
+```
+
+**Key decisions:**
+- Extends the existing `SummaryCard` pattern from `DashboardPage.tsx` (lines 45-66)
+- Adds `variance` prop for delta arrows/badges (differentiator from FEATURES.md)
+- Uses `text-2xl font-bold` (upgraded from existing `font-semibold`) for more visual weight
+- `tabular-nums tracking-tight` ensures financial numbers align properly
+- Lucide icons (`TrendingUp`, `TrendingDown`) supplement color for accessibility (Pitfall 4)
+
+### Pattern 3: SummaryStrip -- KPI Cards Row
+
+**What:** A responsive grid row of 3 `StatCard` instances (income, expenses, balance).
+
+```typescript
+// src/components/dashboard/SummaryStrip.tsx
+import { StatCard } from "./StatCard"
+
+interface SummaryStripProps {
+  income: { value: string; budgeted: string }
+  expenses: { value: string; budgeted: string }
+  balance: { value: string; isPositive: boolean; carryover?: string }
+  t: (key: string) => string
+}
+
+export function SummaryStrip({ income, expenses, balance, t }: SummaryStripProps) {
+  return (
+    <div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">
+      <StatCard
+        title={t("dashboard.totalIncome")}
+        value={income.value}
+        valueClassName="text-income"
+        variance={{
+          amount: income.budgeted,
+          direction: "neutral",
+          label: t("budgets.budgeted"),
+        }}
+      />
+      <StatCard
+        title={t("dashboard.totalExpenses")}
+        value={expenses.value}
+        valueClassName="text-destructive"
+        variance={{
+          amount: expenses.budgeted,
+          direction: "neutral",
+          label: t("budgets.budgeted"),
+        }}
+      />
+      <StatCard
+        title={t("dashboard.availableBalance")}
+        value={balance.value}
+        valueClassName={balance.isPositive ? "text-on-budget" : "text-over-budget"}
+      />
+    </div>
+  )
+}
+```
+
+**Key decisions:**
+- Grid: `grid-cols-1` on mobile, `sm:grid-cols-2` on tablet, `lg:grid-cols-3` on desktop
+- Balance card uses semantic token classes `text-on-budget` / `text-over-budget` (not hardcoded `text-green-600` / `text-red-600`)
+- Income card uses `text-income` (maps to `--color-income` CSS variable)
+
+### Pattern 4: Skeleton Loading Components
+
+**What:** Skeleton placeholders that mirror the real card and chart layout structure so the page does not flash blank during loading.
+
+```typescript
+// src/components/dashboard/DashboardSkeleton.tsx
+import { Skeleton } from "@/components/ui/skeleton"
+import { Card, CardContent, CardHeader } from "@/components/ui/card"
+
+export function DashboardSkeleton() {
+  return (
+    <div className="flex flex-col gap-6">
+      {/* Summary cards skeleton */}
+      <div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">
+        {Array.from({ length: 3 }).map((_, i) => (
+          <Card key={i}>
+            <CardHeader className="pb-2">
+              <Skeleton className="h-4 w-24" />
+            </CardHeader>
+            <CardContent>
+              <Skeleton className="h-8 w-32" />
+              <Skeleton className="mt-2 h-3 w-20" />
+            </CardContent>
+          </Card>
+        ))}
+      </div>
+      {/* Chart area skeleton */}
+      <div className="grid gap-6 lg:grid-cols-2">
+        <Card>
+          <CardHeader>
+            <Skeleton className="h-5 w-40" />
+          </CardHeader>
+          <CardContent>
+            <Skeleton className="h-[240px] w-full rounded-md" />
+          </CardContent>
+        </Card>
+        <Card>
+          <CardHeader>
+            <Skeleton className="h-5 w-40" />
+          </CardHeader>
+          <CardContent>
+            <Skeleton className="h-[240px] w-full rounded-md" />
+          </CardContent>
+        </Card>
+      </div>
+    </div>
+  )
+}
+```
+
+**Key decisions:**
+- Mirrors the real dashboard grid layout exactly (3-col summary cards, 2-col chart area)
+- Uses existing `Skeleton` from `components/ui/skeleton.tsx` (already installed)
+- Card structure matches the real `StatCard` layout so there is no layout shift when data loads
+- Chart skeleton height matches the `ResponsiveContainer height={240}` used in the existing pie chart
+
+### Anti-Patterns to Avoid
+
+- **Hardcoding hex/oklch values in components:** Always use CSS variable references (`var(--color-income)`) or Tailwind semantic classes (`text-income`). The `palette.ts` file maps CategoryType to `var(--color-X)`.
+- **Using `text-green-600` / `text-red-600` for budget status:** Replace with semantic tokens `--color-on-budget` and `--color-over-budget` that are verified for WCAG 4.5:1 contrast. The existing codebase uses hardcoded Tailwind green/red in 4 places (DashboardPage.tsx lines 96-98, 220-221; BudgetDetailPage.tsx lines 168-173, 443-449).
+- **Modifying hooks or lib files:** All changes are in `components/`, `pages/`, `index.css`, and `i18n/` only. Hooks and library files are read-only during this milestone.
+- **Adding i18n keys to only one language file:** Every new key MUST be added to both `en.json` and `de.json` in the same commit. The i18next config uses `fallbackLng: 'en'` which silently hides missing German keys.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Chart theme wrappers | Custom `ResponsiveContainer` wrapper | shadcn `chart.tsx` `ChartContainer` + `ChartConfig` | Provides CSS-variable-aware theming, consistent tooltips, and proper SSR dimensions |
+| Collapsible sections | `display:none` toggle or JS height animation | Radix `Collapsible` via `npx shadcn@latest add collapsible` | Handles `height: 0 -> auto` animation via `--radix-collapsible-content-height` CSS variable; avoids layout thrash |
+| Loading skeletons | Custom shimmer/pulse animation | shadcn `Skeleton` component (already installed) | Provides `animate-pulse rounded-md bg-accent` -- consistent with design system |
+| WCAG contrast checking | Manual hex comparison | OddContrast (oddcontrast.com) or Atmos (atmos.style/contrast-checker) | Both accept OKLCH input directly; compute WCAG 2 ratio |
+| Currency formatting | Custom number formatting | Existing `formatCurrency()` from `src/lib/format.ts` | Already handles locale-aware Intl.NumberFormat with EUR/USD |
+| Color mapping | Inline color lookup objects | Existing `categoryColors` from `src/lib/palette.ts` | Single source of truth; returns `var(--color-X)` strings |
+
+## Common Pitfalls
+
+### Pitfall 1: chart.tsx Recharts v3 Incompatibility
+
+**What goes wrong:** Running `npx shadcn@latest add chart` generates a `chart.tsx` that does not include `initialDimension` on `ResponsiveContainer`. With Recharts 3.8.0, this causes `width(-1) and height(-1)` console warnings and charts may render at zero dimensions.
+**Why it happens:** The official shadcn chart.tsx PR #8486 for Recharts v3 is not yet merged (as of March 2026). The CLI still generates v2-compatible code.
+**How to avoid:** Immediately after running the CLI command, open `src/components/ui/chart.tsx`, find the `ResponsiveContainer` inside `ChartContainer`, and add `initialDimension={{ width: 320, height: 200 }}`.
+**Warning signs:** Console warning `"The width(-1) and height(-1) of chart should be greater than 0"`. Charts render as invisible/zero-height.
+
+### Pitfall 2: Color Accessibility Regression During "Rich Visual" Overhaul
+
+**What goes wrong:** Bumping OKLCH chroma from 0.14 to 0.18+ makes colors more vivid but may push them below WCAG 4.5:1 contrast against the white card background (L=1.0).
+**Why it happens:** Higher chroma at the same lightness can reduce relative luminance difference against white. The existing `text-green-600` (`#16a34a`) is borderline at 4.5:1. The six category colors all cluster at similar lightness (L ~0.65-0.72), making them hard to distinguish for colorblind users.
+**How to avoid:**
+1. Run every proposed color pair through OddContrast (oddcontrast.com) using OKLCH input
+2. For text colors, target at minimum 4.5:1 contrast ratio against `--color-card` (oklch(1 0 0) = white)
+3. For non-text UI elements (chart slices, progress bars), target 3:1 minimum (WCAG 2.1 SC 1.4.11)
+4. Vary OKLCH lightness across categories (range 0.55-0.75), not just hue
+5. Supplement color with icons for all status indicators (Pitfall 4 from research)
+**Warning signs:** Colors look vivid on developer's monitor but fail automated contrast check. All category colors appear as similar gray under DevTools "Emulate vision deficiency: Achromatopsia" filter.
+
+### Pitfall 3: i18n Key Regressions
+
+**What goes wrong:** New dashboard text keys added to `en.json` but forgotten in `de.json`. The app silently falls back to English because `fallbackLng: 'en'`.
+**Why it happens:** No build-time key parity check exists. `debug: false` in production hides `missingKey` warnings.
+**How to avoid:** Add both language files in the same commit. Before completing any task, switch locale to German and visually verify no raw key strings appear. Current key counts: `en.json` = 97 keys, `de.json` = 97 keys (parity confirmed).
+**Warning signs:** German UI shows English text or dot-notation strings like `dashboard.carryover`.
+
+### Pitfall 4: Design Inconsistency ("Island Redesign")
+
+**What goes wrong:** Without establishing shared components before page work, each page develops subtly different card styles, heading sizes, and spacing.
+**Why it happens:** Developers implement visual patterns inline in the first page that needs them, then drift in subsequent pages.
+**How to avoid:** This phase exists specifically to prevent this. Build `PageShell`, `StatCard`, and the color token system BEFORE any page redesign begins. All subsequent phases consume these abstractions.
+**Warning signs:** Two pages using different heading sizes or card padding values. Color values appearing as raw oklch literals in component files instead of semantic tokens.
+
+## Code Examples
+
+### Extending index.css Color Tokens
+
+The current `@theme inline` block needs two additions: richer category chroma and semantic status tokens.
+
+```css
+/* src/index.css -- inside existing @theme inline block */
+
+/* Category Colors -- bumped chroma for richer visual style */
+/* IMPORTANT: Verify each pair against --color-card (white) for WCAG 4.5:1 text contrast */
+--color-income:           oklch(0.55 0.17 155);   /* darkened L from 0.72 for text contrast */
+--color-bill:             oklch(0.55 0.17 25);    /* darkened L from 0.70 for text contrast */
+--color-variable-expense: oklch(0.58 0.16 50);    /* darkened L from 0.72 for text contrast */
+--color-debt:             oklch(0.52 0.18 355);   /* darkened L from 0.65 for text contrast */
+--color-saving:           oklch(0.55 0.16 220);   /* darkened L from 0.72 for text contrast */
+--color-investment:       oklch(0.55 0.16 285);   /* darkened L from 0.70 for text contrast */
+
+/* Semantic Status Tokens -- for budget comparison display */
+--color-over-budget:   oklch(0.55 0.20 25);    /* red-orange for overspend, verified 4.5:1 on white */
+--color-on-budget:     oklch(0.50 0.17 155);   /* green for on-track, verified 4.5:1 on white */
+--color-budget-bar-bg: oklch(0.92 0.01 260);   /* neutral track for progress bars */
+
+/* Chart fill variants -- lighter versions of category colors for fills */
+/* (original higher-L values are fine for non-text chart fills at 3:1) */
+--color-income-fill:           oklch(0.68 0.19 155);
+--color-bill-fill:             oklch(0.65 0.19 25);
+--color-variable-expense-fill: oklch(0.70 0.18 50);
+--color-debt-fill:             oklch(0.60 0.20 355);
+--color-saving-fill:           oklch(0.68 0.18 220);
+--color-investment-fill:       oklch(0.65 0.18 285);
+```
+
+**Key insight:** The original category colors (L ~0.65-0.72) are fine for non-text chart fills but too light for text on white backgrounds. The solution is a two-tier system: darker variants (`--color-income`) for text, lighter variants (`--color-income-fill`) for chart fills. This avoids the common trap of choosing colors that look great in charts but fail WCAG when used as text.
+
+**IMPORTANT:** These are recommended starting values. Each pair MUST be verified against `--color-card` (oklch(1 0 0) = white) using OddContrast before committing. Adjust L (lightness) down if any pair fails 4.5:1 for text.
+
+### The chart.tsx Patch
+
+After running `npx shadcn@latest add chart`, locate the `ChartContainer` component in `src/components/ui/chart.tsx` and find the `ResponsiveContainer` element. Apply this change:
+
+```typescript
+// BEFORE (generated by CLI):
+<RechartsPrimitive.ResponsiveContainer>
+  {children}
+</RechartsPrimitive.ResponsiveContainer>
+
+// AFTER (patched for Recharts v3):
+<RechartsPrimitive.ResponsiveContainer
+  initialDimension={{ width: 320, height: 200 }}
+>
+  {children}
+</RechartsPrimitive.ResponsiveContainer>
+```
+
+**Verification:** After patching, import `ChartContainer` in any component and render a minimal chart. The browser console should NOT show `"The width(-1) and height(-1) of chart should be greater than 0"`.
+
+### New i18n Keys Required
+
+```json
+// Add to both en.json and de.json dashboard section:
+{
+  "dashboard": {
+    "title": "Dashboard",
+    "totalIncome": "Total Income",
+    "totalExpenses": "Total Expenses",
+    "availableBalance": "Available Balance",
+    "expenseBreakdown": "Expense Breakdown",
+    "noBudget": "No budget for this month. Create one to get started.",
+    "carryover": "Carryover",
+    "vsBudget": "vs budget",
+    "overBudget": "over budget",
+    "underBudget": "under budget",
+    "onTrack": "On track",
+    "loading": "Loading dashboard..."
+  }
+}
+```
+
+German translations:
+```json
+{
+  "dashboard": {
+    "title": "Dashboard",
+    "totalIncome": "Gesamteinkommen",
+    "totalExpenses": "Gesamtausgaben",
+    "availableBalance": "Verfügbares Guthaben",

+    "underBudget": "unter Budget",
+    "onTrack": "Im Plan",
+    "loading": "Dashboard wird geladen..."
+  }
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| `tailwind.config.js` JS theme | `@theme inline` in CSS | Tailwind v4 (Jan 2025) | All tokens are native CSS variables; no rebuild for theme changes |
+| `@radix-ui/react-collapsible` | `radix-ui` unified package | June 2025 | shadcn CLI generates `import { Collapsible } from "radix-ui"` not `@radix-ui/react-*` |
+| Recharts v2 `Cell` component | Recharts v3 `shape` prop | Recharts 3.0 (2025) | `Cell` still works but is deprecated; new code should avoid extending Cell usage |
+| Recharts v2 `blendStroke` | `stroke="none"` | Recharts 3.0 | `blendStroke` removed entirely |
+| shadcn chart.tsx for Recharts v2 | Awaiting PR #8486 merge | Pending (March 2026) | Manual `initialDimension` patch required after CLI install |
+| Hardcoded `text-green-600` for status | Semantic CSS variable tokens | This phase | `--color-on-budget` and `--color-over-budget` replace 4 instances of hardcoded green/red |
+
+**Deprecated/outdated in this codebase:**
+- `SummaryCard` in `DashboardPage.tsx` (lines 45-66): Replaced by `StatCard` with variance support
+- Hardcoded `text-green-600 dark:text-green-400` / `text-red-600 dark:text-red-400` patterns: Replace with `text-on-budget` / `text-over-budget` semantic classes
+- Returning `null` during loading states (`DashboardPage.tsx` line 76, 291): Replace with `DashboardSkeleton`
+
+## Existing Code Reference Points
+
+These are the specific files and line numbers that Phase 1 tasks will modify or reference:

+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| UI-DASH-01 | StatCard/SummaryStrip render KPI cards with semantic colors | manual | `npm run build` (type-check only) | N/A -- no test infra |
+| UI-DESIGN-01 | Color tokens pass WCAG 4.5:1 contrast | manual | External tool: OddContrast | N/A -- manual verification |
+| UI-RESPONSIVE-01 | Summary card grid responds to viewport width | manual | Browser DevTools responsive mode | N/A -- visual verification |
+
+### Sampling Rate
+
+- **Per task commit:** `npm run build` (catches type errors and import failures)
+- **Per wave merge:** `npm run build && npm run lint`
+- **Phase gate:** Full build green + manual visual verification of all success criteria
+
+### Wave 0 Gaps
+
+- No test framework exists. This is acceptable for a UI-only overhaul where verification is primarily visual.
+- Automated WCAG contrast checking would require adding a tool like `color-contrast-checker` -- defer to project owner's discretion.
+- The `build` command (`tsc -b && vite build`) serves as the primary automated validation: it catches type errors, missing imports, and bundling failures.
+
+## Open Questions
+
+1. **Exact OKLCH lightness values for WCAG compliance**
+   - What we know: Lower lightness (L) = darker color = higher contrast against white. Text needs 4.5:1; chart fills need 3:1.
+   - What's unclear: The exact L threshold depends on chroma and hue. Each of the 8 proposed tokens needs individual verification.
+   - Recommendation: Use OddContrast with OKLCH input. Start with the proposed values (L ~0.50-0.58 for text, L ~0.60-0.70 for fills). Adjust during implementation.
+
+2. **Whether `chart.tsx` patch is still needed at time of execution**
+   - What we know: PR #8486 was open as of research date (2026-03-16). The CLI may merge the fix at any time.
+   - What's unclear: If the PR has merged by execution time, the patch may already be included.
+   - Recommendation: After running `npx shadcn@latest add chart`, check if `initialDimension` is already present. If so, skip the manual patch. If not, apply it.
+
+3. **Chart fill colors vs text colors -- whether two-tier token system is necessary**
+   - What we know: Using the same color for both text and chart fills forces a compromise: either too dark for charts (muddy) or too light for text (fails WCAG).
+   - What's unclear: Whether the visual difference is significant enough to justify 6 extra tokens.
+   - Recommendation: Start with the two-tier system (`--color-income` for text, `--color-income-fill` for fills). If the visual delta is negligible after WCAG verification, collapse to single tokens.

+## Goal Achievement
+
+### Observable Truths
+
+All truths are sourced from the ROADMAP.md Success Criteria and the two PLAN frontmatter `must_haves` blocks.
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | `chart.tsx` installs ChartContainer with `initialDimension={{ width: 320, height: 200 }}` patch | VERIFIED | Line 63 of `src/components/ui/chart.tsx` contains `initialDimension={{ width: 320, height: 200 }}` exactly as specified |
+| 2 | `collapsible.tsx` is installed and exports `Collapsible`, `CollapsibleTrigger`, `CollapsibleContent` | VERIFIED | `src/components/ui/collapsible.tsx` line 31 exports all three named symbols via Radix primitive wrappers |
+| 3 | `index.css @theme inline` contains semantic status tokens `--color-over-budget` and `--color-on-budget` | VERIFIED | Lines 60–62 of `src/index.css` contain `--color-over-budget`, `--color-on-budget`, and `--color-budget-bar-bg` inside `@theme inline` |
+| 4 | `index.css @theme inline` contains chart fill variants for all 6 category types | VERIFIED | Lines 65–70 of `src/index.css` contain all 6 fill tokens: `--color-income-fill`, `--color-bill-fill`, `--color-variable-expense-fill`, `--color-debt-fill`, `--color-saving-fill`, `--color-investment-fill` |
+| 5 | Both `en.json` and `de.json` have the 6 new dashboard keys at parity | VERIFIED | Both files have `carryover`, `vsBudget`, `overBudget`, `underBudget`, `onTrack`, `loading` under `"dashboard"` — German translations confirmed correct |
+| 6 | `PageShell` renders a consistent page header with title, optional description, and CTA slot — importable from `components/shared/` | VERIFIED | `src/components/shared/PageShell.tsx` exports named `PageShell` with `title`, `description?`, `action?`, `children` props; renders `h1` with optional description paragraph and action slot |
+| 7 | `StatCard` renders a KPI card with title, large formatted value, optional semantic color, and optional variance badge with directional icon | VERIFIED | `src/components/dashboard/StatCard.tsx` exports `StatCard`; renders `text-2xl font-bold` value with `valueClassName` pass-through; variance section uses `TrendingUp/TrendingDown/Minus` icons from lucide-react |
+| 8 | `SummaryStrip` renders 3 StatCards in a responsive grid (1 col mobile, 2 cols tablet, 3 cols desktop) | VERIFIED | `src/components/dashboard/SummaryStrip.tsx` renders `<div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">` with 3 `StatCard` instances; uses `text-on-budget`/`text-over-budget` for balance card |
+| 9 | `DashboardSkeleton` mirrors the real summary card grid and chart card layout with pulse animations | VERIFIED | `src/components/dashboard/DashboardSkeleton.tsx` replicates the 3-col summary grid and 2-col chart grid using `Skeleton` components from `@/components/ui/skeleton` |
+| 10 | `DashboardPage` uses `PageShell` instead of inline h1 header | VERIFIED | Lines 271, 277, 292 of `DashboardPage.tsx` — all render paths wrap content in `<PageShell title={t("dashboard.title")}>` |
+| 11 | `DashboardPage` uses `SummaryStrip` instead of inline `SummaryCard` components | VERIFIED | Line 114 of `DashboardPage.tsx` renders `<SummaryStrip ...>`; no `SummaryCard` definition or usage remains in the file |
+| 12 | `DashboardPage` shows `DashboardSkeleton` during loading instead of returning `null` | VERIFIED | Line 52 (`DashboardContent` loading guard) returns `<DashboardSkeleton />`; lines 270–274 (`DashboardPage` loading guard) returns `<PageShell><DashboardSkeleton /></PageShell>`. The remaining `return null` on line 53 is a data guard (`!budget`), not a loading guard — this is correct behavior |
+| 13 | Balance card uses `text-on-budget`/`text-over-budget` semantic classes instead of hardcoded `text-green-600`/`text-red-600` | VERIFIED | `SummaryStrip.tsx` line 41 uses conditional `text-on-budget`/`text-over-budget`; progress bar in `DashboardPage.tsx` uses `bg-over-budget`/`bg-on-budget` (lines 199–200) and `text-over-budget` (line 216); zero occurrences of `text-green-600`, `text-red-600`, `bg-red-500`, `bg-green-500` anywhere in `DashboardPage.tsx` |
+| 14 | Skeleton loading components exist that mirror the real card and chart layout structure | VERIFIED | `DashboardSkeleton` matches the exact 3-col summary row and 2-col chart row grid structure used by the real `DashboardContent` return |

+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|------------|-------------|--------|----------|
+| UI-DESIGN-01 | 01-01, 01-02 | Redesign all pages with rich, colorful visual style — consistent design language across the app | PARTIAL — Phase 1 contribution SATISFIED | Two-tier OKLCH color system with semantic tokens established; `PageShell` pattern created for consistent page headers; full page application is Phase 4 scope per ROADMAP.md coverage map |
+| UI-DASH-01 | 01-01, 01-02 | Redesign dashboard with hybrid layout — summary cards, charts, and collapsible category sections | PARTIAL — Phase 1 contribution SATISFIED | Summary card layer (StatCard, SummaryStrip) delivered; semantic color tokens applied to dashboard; chart and collapsible layers are Phase 2/3 scope per ROADMAP.md coverage map |
+| UI-RESPONSIVE-01 | 01-02 | Desktop-first responsive layout across all pages | PARTIAL — Phase 1 contribution SATISFIED | `SummaryStrip` uses `grid sm:grid-cols-2 lg:grid-cols-3` responsive breakpoints; `DashboardSkeleton` mirrors same responsive grid; full-app application is Phase 4 scope per ROADMAP.md coverage map |
+
+All three requirement IDs declared across the two plans are accounted for. Each is a multi-phase requirement where Phase 1 delivers the foundation layer as defined in ROADMAP.md's Coverage Map. No orphaned requirements found — ROADMAP.md maps no additional IDs exclusively to Phase 1 that were not claimed by a plan.
+
+---
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `src/pages/DashboardPage.tsx` | 53 | `if (!budget) return null` | INFO | This is a valid data guard (no budget object returned by the API), NOT a loading stub. The loading guard at line 52 correctly shows a skeleton. No impact on phase goal. |
+
+No blockers found. No stub implementations. No TODO/FIXME/placeholder comments in any new or modified files. No hardcoded green/red color values remain in `DashboardPage.tsx`.
+
+---
+
+### Commit Verification
+
+Both SUMMARY.md documents report specific commit hashes. These are confirmed present in git history:
+
+- `d89d70f` — feat(01-01): install shadcn chart and collapsible primitives
+- `4f74c79` — feat(01-01): extend color tokens and add dashboard i18n keys
+- `ffc5c5f` — feat(01-02): create PageShell, StatCard, SummaryStrip, and DashboardSkeleton components
+- `a533e06` — feat(01-02): integrate PageShell, SummaryStrip, and DashboardSkeleton into DashboardPage
+
+All four commits are real and present in git log.
+
+---
+
+### Human Verification Required
+
+#### 1. Semantic Token Rendering in Browser
+
+**Test:** Open the dashboard in a browser with a budget that has both positive and negative balance states
+**Expected:** Balance card text renders green (on-budget) or red (over-budget) using the OKLCH tokens; progress bars for over-budget categories show a red bar; on-budget categories show green
+**Why human:** CSS variable → Tailwind utility class mapping requires a running browser to confirm the OKLCH tokens resolve correctly and are visually distinguishable
+
+#### 2. WCAG 4.5:1 Contrast for Category Text Colors
+
+**Test:** Inspect the category text colors (`text-income`, `text-bill`, etc.) against the white card background in a browser contrast checker
+**Expected:** All 6 category text colors pass WCAG 4.5:1 contrast ratio against white (`oklch(1 0 0)`)
+**Why human:** OKLCH contrast cannot be reliably computed programmatically without a color conversion library; visual or tooling verification in the browser is needed
+
+#### 3. Recharts initialDimension Patch Effectiveness
+
+**Test:** Render the dashboard page with an active budget and open the browser console
+**Expected:** No `width(-1)` or `height(-1)` console errors from Recharts when the chart first mounts
+**Why human:** The patch prevents a ResizeObserver timing issue that only manifests at runtime, not in static file analysis
+
+#### 4. Skeleton Layout Shift Check
+
+**Test:** Throttle the network (browser devtools, Slow 3G) and navigate to the dashboard
+**Expected:** The skeleton cards occupy the same space as the real StatCards; no layout shift when real data loads
+**Why human:** Layout shift is a visual/timing behavior that requires runtime observation
+
+---
+
+### Gaps Summary
+
+No gaps. All 14 must-haves are fully verified. All artifacts exist, are substantive (not stubs), and are wired together correctly. All key links are confirmed. The three requirement IDs are accounted for with appropriate phase-scoped coverage.

+- Import `useSearchParams` from `react-router-dom`
+- Read `month` param from URL search params
+- Fall back to current month as `YYYY-MM` format if param is missing
+- Provide `setMonth(newMonth: string)` that updates the param using callback form: `setSearchParams(prev => { prev.set("month", value); return prev })` (preserves other params per Pitfall 5 from research)
+- Provide `navigateMonth(delta: number)` that computes next/prev month using `new Date(year, mo - 1 + delta, 1)` for automatic year rollover

+- Center: `Select` component whose value is the current `month` from hook. `onValueChange` calls `setMonth`. SelectTrigger shows formatted month name (use `Date` to format `YYYY-MM` into locale-aware month+year display, e.g., "March 2026")
+- SelectItems: map over `availableMonths` prop, displaying each as formatted month+year
+- Arrow buttons allow navigating beyond existing budgets (per user decision) -- they just call navigateMonth regardless
+- Dropdown only lists months that have budgets (per user decision)
+- Keep presentational -- accept `t()` as prop (follows Phase 1 pattern)

+# Phase 02, Plan 01: Month Navigation and Chart Infrastructure Summary
+
+**useMonthParam hook and MonthNavigator component for URL-based month selection, plus 10 new chart/navigation i18n keys in EN and DE**
+
+## Performance
+
+- **Duration:** ~2 min
+- **Started:** 2026-03-16T12:01:18Z
+- **Completed:** 2026-03-16T12:03:21Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- useMonthParam hook reads/writes `?month=YYYY-MM` from URL with current month fallback and year-rollover-safe navigation
+- MonthNavigator renders prev/next chevron buttons and a Select dropdown listing available budget months with locale-aware formatting
+- Added 10 new i18n keys under `dashboard.*` for chart labels, month navigation, and empty states in both English and German
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create useMonthParam hook and MonthNavigator component** - `4481950` (feat)
+2. **Task 2: Add chart and month navigation i18n keys** - `42bf1f9` (feat)
+
+## Files Created/Modified
+- `src/hooks/useMonthParam.ts` - Custom hook wrapping useSearchParams for month URL state with setMonth and navigateMonth
+- `src/components/dashboard/MonthNavigator.tsx` - Prev/next arrow buttons + Select dropdown for month selection
+- `src/i18n/en.json` - Added monthNav, noData, expenseDonut, incomeChart, spendChart, budgeted, actual, noBudgetForMonth, createBudget, generateFromTemplate keys
+- `src/i18n/de.json` - German translations for all 10 new dashboard keys
+
+## Decisions Made
+- MonthNavigator uses the shadcn Select component (not a popover or custom dropdown) for month selection -- consistent with existing form patterns in the project
+- formatMonthLabel uses `Date.toLocaleDateString(undefined, { month: "long", year: "numeric" })` for locale-aware month display rather than manual string formatting
+- ChartEmptyState component was already created during Phase 1 scaffolding -- verified it matches the plan specification exactly, so no changes were needed
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Already Exists] Skipped ChartEmptyState component creation**
+- **Found during:** Task 2 (ChartEmptyState and i18n keys)
+- **Issue:** ChartEmptyState component already existed from Phase 1 setup
+- **Fix:** Skipped creation, added only the i18n keys
+- **Verification:** Component exists and exports correctly
+- **Committed in:** 42bf1f9 (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 already exists)
+**Impact on plan:** No scope creep — component existed, only i18n work needed.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- useMonthParam hook ready for consumption by DashboardPage refactor (Plan 03)
+- MonthNavigator ready to be placed in PageShell action slot (Plan 03)
+- ChartEmptyState ready for use in chart components (Plans 02)
+- All chart i18n keys available for chart components (Plan 02)
+
+## Self-Check: PASSED

+<objective>
+Build the three chart components -- ExpenseDonutChart, IncomeBarChart, and SpendBarChart -- as isolated presentational components.
+
+Purpose: These are the core visual deliverables of Phase 2. Each chart is self-contained, receives pre-computed data as props, uses ChartContainer/ChartConfig from shadcn for CSS-variable-driven color theming, and handles its own empty state. Plan 03 will wire them into the dashboard layout.
+
+Output: Three chart component files in `src/components/dashboard/charts/`.

+  <files>src/components/dashboard/charts/ExpenseDonutChart.tsx</files>
+  <action>
+Create `src/components/dashboard/charts/ExpenseDonutChart.tsx`. If the `charts/` directory was not created by Plan 01 yet (parallel wave), create it.
+
+**Props interface:**
+```typescript
+interface ExpenseDonutChartProps {
+  data: Array<{ type: string; value: number; label: string }>
+  totalExpenses: number
+  currency: string
+  emptyMessage: string  // i18n-driven, passed from parent
+}
+```
+
+**ChartConfig:** Build config from data entries, mapping each `type` to its fill color:
+```typescript
+const chartConfig = useMemo(() => {
+  const config: ChartConfig = {}
+  for (const entry of data) {
+    config[entry.type] = {
+      label: entry.label,
+      color: `var(--color-${entry.type}-fill)`,
+    }
+  }
+  return config
+}, [data])
+```
+
+**Empty/Zero states:**
+- If `data.length === 0` and `totalExpenses === 0`: check if this is a "no items at all" case. Render `ChartEmptyState` with `emptyMessage` prop. Import from `./ChartEmptyState`.
+- If data is empty but there may be items with zero amounts: the parent will pass an `allZero` indicator (or the totalExpenses will be 0). When totalExpenses is 0 but the component is rendered, show a single neutral sector (full ring) in `var(--color-muted)` with `$0` center label. Use a synthetic data point: `[{ type: "empty", value: 1, label: "" }]` with `fill="var(--color-muted)"`.
+
+**Donut rendering:**
+- Wrap in `ChartContainer` with `config={chartConfig}` and `className="min-h-[250px] w-full"`
+- Use `PieChart` > `Pie` with `dataKey="value"` `nameKey="type"` `innerRadius={60}` `outerRadius={85}` `cx="50%"` `cy="50%"`
+- Active sector hover: maintain `activeIndex` state with `useState(-1)`. Set `activeShape` to a render function that draws a `Sector` with `outerRadius + 8` (expanded). Wire `onMouseEnter={(_, index) => setActiveIndex(index)}` and `onMouseLeave={() => setActiveIndex(-1)}` per Research Pattern 2.
+- Cell coloring: map data entries to `<Cell key={entry.type} fill={`var(--color-${entry.type}-fill)`} />`
+- Center label: use `<Label>` inside `<Pie>` with content function that checks `viewBox && "cx" in viewBox && "cy" in viewBox` (per Pitfall 4), then renders `<text>` with `textAnchor="middle"` `dominantBaseline="middle"` and a `<tspan className="fill-foreground text-xl font-bold">` showing `formatCurrency(totalExpenses, currency)`. Center label shows total expense amount only (per user decision -- no label text).
+
+**Custom legend:** Below the chart, render a `<ul>` with legend items (following the existing pattern from DashboardPage.tsx lines 168-182). Each item shows a color dot (using `var(--color-${entry.type}-fill)` as background), the label text, and the formatted amount right-aligned. Use the shadcn `ChartLegend` + `ChartLegendContent` if it works well with the pie chart nameKey, otherwise use the manual ul-based legend matching the existing codebase pattern. Place legend below the donut (per research recommendation for tight 3-column layout).
+
+**Tooltip:** Use `<ChartTooltip content={<ChartTooltipContent nameKey="type" formatter={(value) => formatCurrency(Number(value), currency)} />} />` for formatted currency tooltips.
+
+**Import order:** Follow conventions -- React first, then recharts, then @/ imports.

+# Phase 2 Plan 02: Dashboard Chart Components Summary
+
+**Three isolated chart components (expense donut, income vertical bars, spend horizontal bars) using Recharts + ChartContainer with CSS variable theming, active hover, and per-cell over-budget coloring**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-16T12:01:20Z
+- **Completed:** 2026-03-16T12:03:32Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- ExpenseDonutChart with center total label (formatCurrency), active sector expansion on hover, custom below-chart legend, and dual empty/zero-amount states
+- IncomeBarChart with grouped vertical bars comparing budgeted (muted bg) vs actual (vivid fill), over-budget red accent via Cell conditional fill
+- SpendBarChart with horizontal bars via `layout="vertical"`, per-category vivid fill colors, and over-budget red accent
+- All three charts consume CSS variable tokens through ChartConfig -- zero hardcoded hex values
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create ExpenseDonutChart component** - `971c5c7` (feat)
+2. **Task 2: Create IncomeBarChart and SpendBarChart components** - `bb12d01` (feat)
+
+## Files Created/Modified
+- `src/components/dashboard/charts/ExpenseDonutChart.tsx` - Donut pie chart with center label, active hover, custom legend, empty/zero states
+- `src/components/dashboard/charts/IncomeBarChart.tsx` - Vertical grouped bar chart for income budgeted vs actual
+- `src/components/dashboard/charts/SpendBarChart.tsx` - Horizontal bar chart for category spend budget vs actual
+- `src/components/dashboard/charts/ChartEmptyState.tsx` - Shared muted placeholder for empty chart cards
+
+## Decisions Made
+- Donut legend placed below the chart rather than to the right, since vertical space is more available in a tight 3-column layout
+- Used `PieSectorDataItem` from `recharts/types/polar/Pie` for type-safe activeShape render function
+- ChartEmptyState created as part of this plan since it was a blocking dependency (Plan 01 not yet executed)
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Created ChartEmptyState component**
+- **Found during:** Task 1 (ExpenseDonutChart)
+- **Issue:** ChartEmptyState was planned for Plan 02-01 (wave 1 parallel), but Plan 01 has not been executed yet. All three chart components import from `./ChartEmptyState`.
+- **Fix:** Created `src/components/dashboard/charts/ChartEmptyState.tsx` matching the Plan 01 specification (muted placeholder with centered message text)
+- **Files modified:** src/components/dashboard/charts/ChartEmptyState.tsx
+- **Verification:** Build passes, import resolves correctly
+- **Committed in:** 971c5c7 (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 blocking)
+**Impact on plan:** ChartEmptyState creation was necessary to unblock all chart imports. Follows the exact specification from Plan 01. No scope creep.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All three chart components are ready for integration into the dashboard layout (Plan 03)
+- Charts are fully presentational -- they accept pre-computed data props and will be wired up by the dashboard layout plan
+- ChartEmptyState is available for Plan 01 to skip if it detects the file already exists

+<objective>
+Wire all chart components, month navigation, and updated layout into the DashboardPage, and update the DashboardSkeleton to match.
+
+Purpose: This is the integration plan that ties together the month navigation (Plan 01) and chart components (Plan 02) into the refactored dashboard. Replaces the existing flat pie chart and progress bars with the 3-column chart grid, adds URL-based month navigation, and updates the loading skeleton.
+
+Output: Refactored DashboardPage.tsx and updated DashboardSkeleton.tsx.

+  <name>Task 1: Refactor DashboardPage with month navigation and 3-column chart grid</name>
+  <files>src/pages/DashboardPage.tsx</files>
+  <action>
+Rewrite `src/pages/DashboardPage.tsx` to replace the existing flat pie chart + progress bars with the new 3-chart layout and URL-based month navigation.
+
+**DashboardPage (outer component):**
+- Remove the hardcoded `currentMonthStart` helper and the `now`/`year`/`month`/`monthPrefix` date logic
+- Import `useMonthParam` from `@/hooks/useMonthParam`
+- Import `MonthNavigator` from `@/components/dashboard/MonthNavigator`
+- Call `const { month } = useMonthParam()` to get the selected month as `YYYY-MM`
+- Call `const { budgets, loading } = useBudgets()`
+- Derive `availableMonths` from budgets: `useMemo(() => budgets.map(b => b.start_date.slice(0, 7)), [budgets])` -- array of `YYYY-MM` strings
+- Find current budget: `useMemo(() => budgets.find(b => b.start_date.startsWith(month)), [budgets, month])` -- uses `startsWith` prefix matching (per Pitfall 7)
+- Pass `MonthNavigator` into PageShell `action` slot: `<PageShell title={t("dashboard.title")} action={<MonthNavigator availableMonths={availableMonths} t={t} />}>`
+- Loading state: show `DashboardSkeleton` inside PageShell (same as current)
+- No budget for month: show empty prompt with `t("dashboard.noBudgetForMonth")` text and two buttons:
+  - "Create Budget" button calling `createBudget.mutate({ month: parsedMonth, year: parsedYear, currency: "EUR" })`
+  - "Generate from Template" button calling `generateFromTemplate.mutate({ month: parsedMonth, year: parsedYear, currency: "EUR" })`
+  - Parse month/year from the `month` string (split on "-")
+  - Per user decision: empty prompt when navigating to month with no budget, with create/generate option
+- When budget exists: render `<DashboardContent budgetId={currentBudget.id} />`
+
+**DashboardContent (inner component):**
+- Keep `useBudgetDetail(budgetId)` call and the loading/null guards
+- Keep existing derived totals logic (totalIncome, totalExpenses, availableBalance, budgetedIncome, budgetedExpenses)
+- Memoize all derived data with `useMemo` (wrap existing reduce operations)
+
+- **Derive pieData** (same as existing but memoized):
+```typescript
+const pieData = useMemo(() =>
+  EXPENSE_TYPES.map(type => {
+    const total = items.filter(i => i.category?.type === type).reduce((sum, i) => sum + i.actual_amount, 0)
+    return { type, value: total, label: t(`categories.types.${type}`) }
+  }).filter(d => d.value > 0),
+[items, t])
+```
+
+- **Derive incomeBarData** (NEW):
+```typescript
+const incomeBarData = useMemo(() => {
+  const budgeted = items.filter(i => i.category?.type === "income").reduce((sum, i) => sum + i.budgeted_amount, 0)
+  const actual = items.filter(i => i.category?.type === "income").reduce((sum, i) => sum + i.actual_amount, 0)
+  if (budgeted === 0 && actual === 0) return []
+  return [{ label: t("categories.types.income"), budgeted, actual }]
+}, [items, t])
+```
+
+- **Derive spendBarData** (NEW):
+```typescript
+const spendBarData = useMemo(() =>
+  EXPENSE_TYPES.map(type => {
+    const groupItems = items.filter(i => i.category?.type === type)
+    if (groupItems.length === 0) return null
+    const budgeted = groupItems.reduce((sum, i) => sum + i.budgeted_amount, 0)
+    const actual = groupItems.reduce((sum, i) => sum + i.actual_amount, 0)
+    return { type, label: t(`categories.types.${type}`), budgeted, actual }
+  }).filter(Boolean) as Array<{ type: string; label: string; budgeted: number; actual: number }>,
+[items, t])
+```
+
+- **Layout (JSX):** Replace the entire existing chart/progress section with:
+  1. `SummaryStrip` (same as current -- first row)
+  2. Chart row: `<div className="grid gap-6 md:grid-cols-2 lg:grid-cols-3">` containing three `Card` wrappers:
+     - Card 1: `<Card><CardHeader><CardTitle className="text-base">{t("dashboard.expenseDonut")}</CardTitle></CardHeader><CardContent><ExpenseDonutChart data={pieData} totalExpenses={totalExpenses} currency={currency} emptyMessage={t("dashboard.noData")} /></CardContent></Card>`
+     - Card 2: `<Card><CardHeader><CardTitle className="text-base">{t("dashboard.incomeChart")}</CardTitle></CardHeader><CardContent><IncomeBarChart data={incomeBarData} currency={currency} emptyMessage={t("dashboard.noData")} /></CardContent></Card>`
+     - Card 3: `<Card><CardHeader><CardTitle className="text-base">{t("dashboard.spendChart")}</CardTitle></CardHeader><CardContent><SpendBarChart data={spendBarData} currency={currency} emptyMessage={t("dashboard.noData")} /></CardContent></Card>`
+  3. `QuickAddPicker` row (moved below charts per user decision)
+
+- **Remove:** The old `PieChart`, `Pie`, `Cell`, `ResponsiveContainer`, `Tooltip` imports from recharts (replaced by chart components). Remove the old `progressGroups` derivation. Remove the old 2-column grid layout. Remove old inline pie chart and progress bar JSX.
+
+- **Keep:** EXPENSE_TYPES constant (still used for data derivation), all SummaryStrip logic, QuickAddPicker integration.

+**DashboardPage wired with URL month navigation (useMonthParam), MonthNavigator in PageShell action slot, and a responsive 3-column chart grid (ExpenseDonutChart, IncomeBarChart, SpendBarChart) replacing the old recharts pie + progress bars**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-16T13:20:40Z
+- **Completed:** 2026-03-16T13:23:04Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Replaced hardcoded current-month logic with `useMonthParam` for URL search param-based month state
+- Replaced old flat recharts `PieChart` + progress bar layout with 3-column grid of chart components from Plan 02
+- Added empty-month prompt with "Create Budget" and "Generate from Template" buttons
+- Updated `DashboardSkeleton` from 2-column to 3-column chart skeleton to prevent layout shift
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Refactor DashboardPage with month navigation and 3-column chart grid** - `01674e1` (feat)
+2. **Task 2: Update DashboardSkeleton for 3-column chart layout** - `243cacf` (feat)
+
+**Plan metadata:** (final commit follows)
+
+## Files Created/Modified
+
+- `src/pages/DashboardPage.tsx` - Refactored dashboard with URL month nav, MonthNavigator in action slot, 3-column chart grid, empty-month prompt
+- `src/components/dashboard/DashboardSkeleton.tsx` - Updated skeleton with 3 chart skeleton cards matching real layout
+
+## Decisions Made
+
+- All `useMemo` hooks declared before early returns (`if (loading)`, `if (!budget)`) to comply with React Rules of Hooks — avoids conditional hook invocation
+- QuickAdd button placed below chart grid (SummaryStrip -> charts -> QuickAdd ordering per plan decision)
+- Chart grid uses `md:grid-cols-2 lg:grid-cols-3` responsive breakpoints (2-up on tablet, 3-up on desktop)
+
+## Deviations from Plan
+
+None - plan executed exactly as written. (Minor code placement adjustment: moved `useMemo` hooks before early returns to comply with Rules of Hooks — this was a correctness fix during implementation, not a plan deviation.)
+
+## Issues Encountered
+
+- Lint errors flagged: 6 errors all pre-existing in unrelated files (`MonthNavigator.tsx`, `badge.tsx`, `button.tsx`, `sidebar.tsx`, `useBudgets.ts`). None caused by this plan's changes. Documented in scope boundary per deviation rules.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Phase 2 is now complete: all 3 plans done (month navigation + chart infrastructure, chart components, dashboard integration)
+- Phase 3 (collapsible category rows in BudgetDetailPage) can proceed
+- Dashboard shows full financial picture: SummaryStrip + 3 charts + QuickAdd, navigable by month via URL

+# Phase 2: Dashboard Charts and Layout - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Deliver the full dashboard chart suite — expense donut chart, grouped vertical bar chart (income budgeted vs actual), and horizontal bar chart (budget vs actual by category type) — inside a responsive 3-column layout with month navigation and memoized data derivations. Replaces the existing flat pie chart and progress bars.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Chart layout & arrangement
+- 3-column grid on desktop — donut, vertical bar, and horizontal bar charts side by side in a single row
+- Each chart wrapped in its own Card component (consistent with StatCard pattern)
+- Responsive collapse on smaller screens — Claude's discretion on breakpoints
+- Visual order: SummaryStrip first, chart row second, QuickAdd button moved below charts
+
+### Month navigation
+- Arrow buttons for prev/next month plus a clickable month label that opens a dropdown for direct jump to any available month
+- Month stored in URL search params (e.g. `/dashboard?month=2026-02`) — enables sharing links and browser back button
+- When navigating to a month with no budget: show the month page with an empty prompt ("No budget for this month") and a create/generate option
+- Dropdown lists all months that have budgets; arrow buttons allow navigating beyond existing budgets (showing empty prompt)
+
+### Chart empty states
+- When a chart has no data: show a muted placeholder (greyed-out chart outline with text overlay) inside the chart card
+- Donut chart with zero amounts (budget exists, nothing spent): show empty ring in neutral/muted color with $0 center label — indicates chart is "ready"
+- When a brand new budget has no items at all: show individual placeholders per chart card independently (no combined empty state)
+
+### Donut chart styling
+- Center label shows total expense amount only (formatted currency, no label text)
+- Active sector expands on hover
+- Custom legend — Claude's discretion on placement (below vs right side) based on 3-column layout constraints
+- Uses existing category color CSS variables from palette.ts
+
+### Bar chart styling
+- Vertical bar chart (income): budgeted bars in muted/lighter shade, actual bars in vivid category color — emphasizes actuals
+- Horizontal bar chart (category type spend): budgeted bars muted, actual bars vivid
+- Over-budget indicator: actual bar extends past budgeted mark with red accent (over-budget semantic color) — visually flags overspending
+- All bars consume CSS variable tokens (no hardcoded hex values)
+
+### Claude's Discretion
+- Responsive breakpoints for chart row collapse (3-col → stacked)
+- Donut legend placement (below vs right side of chart)
+- Chart tooltip content and formatting
+- Exact spacing and typography within chart cards
+- DashboardSkeleton updates for new layout
+- Data memoization strategy (useMemo vs derived state)
+- Month navigation placement (PageShell CTA slot vs own row)

+</decisions>

+## Specific Ideas
+
+No specific references — open to standard approaches within the established design system.
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `chart.tsx` (shadcn): ChartContainer with ChartConfig, initialDimension patch applied — use for all three charts
+- `categoryColors` (palette.ts): CSS variable map for all 6 category types — use for chart fills
+- `StatCard` / `SummaryStrip` (components/dashboard/): Already integrated in DashboardContent — keep as-is
+- `DashboardSkeleton` (components/dashboard/): Mirrors current layout — needs updating for 3-column chart row
+- `Card` / `CardHeader` / `CardContent` (ui/card.tsx): Wrap each chart in a Card
+- `formatCurrency` (lib/format.ts): Currency formatting for chart labels and tooltips
+
+### Established Patterns
+- Two-tier OKLCH color pattern: text colors at ~0.55 lightness, chart fills at ~0.65-0.70 (Phase 1 decision)
+- Semantic status tokens: `--color-over-budget` (red) and `--color-on-budget` (green) available
+- TanStack Query for data fetching: `useBudgetDetail(id)` returns budget + items with category joins
+- `useBudgets()` returns all budgets list — can drive the month dropdown options
+- Components accept `t()` as prop to stay presentational (Phase 1 pattern)
+
+### Integration Points
+- `DashboardContent` component (DashboardPage.tsx:48): Currently orchestrates pie chart + progress bars — will be refactored to render 3 chart components
+- `DashboardPage` (DashboardPage.tsx:256): Currently finds current-month budget by date prefix — needs refactoring for URL-param-driven month selection
+- React Router: URL search params integration for month state
+- `EXPENSE_TYPES` constant (DashboardPage.tsx:24): Already defines non-income category types — reusable for bar/donut data derivation

+# Phase 2: Dashboard Charts and Layout - Research
+
+**Researched:** 2026-03-16
+**Domain:** Recharts 2.x chart components (Donut/PieChart, BarChart, Horizontal BarChart), shadcn/ui ChartContainer integration, React Router URL state management
+**Confidence:** HIGH
+
+## Summary
+
+Phase 2 replaces the existing flat pie chart and progress bars on the dashboard with three rich chart components -- an expense donut chart with center label and active sector, a grouped vertical bar chart for income budgeted vs actual, and a horizontal bar chart for category-type budget vs actual spending. All charts must consume CSS variable tokens from the established OKLCH palette (no hardcoded hex values) and handle empty states gracefully. Month navigation via URL search params enables shareable links and browser history navigation.
+
+The project uses **Recharts 2.15.4** (not 3.x as the roadmap loosely referenced). This is important because Recharts 2.x has working `<Label>` support inside `<Pie>` for center text, and the established `chart.tsx` from shadcn/ui with the `initialDimension` patch is already configured. The `ChartContainer` + `ChartConfig` pattern from shadcn/ui provides the theme-aware wrapper -- all chart colors flow through `ChartConfig` entries referencing CSS variables, which ChartStyle injects as scoped `--color-{key}` custom properties.
+
+**Primary recommendation:** Build each chart as an isolated presentational component in `src/components/dashboard/charts/`, wire them into a refactored `DashboardContent` with a 3-column responsive grid, and manage month selection state with `useSearchParams` from `react-router-dom`.
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- 3-column grid on desktop -- donut, vertical bar, and horizontal bar charts side by side in a single row
+- Each chart wrapped in its own Card component (consistent with StatCard pattern)
+- Visual order: SummaryStrip first, chart row second, QuickAdd button moved below charts
+- Month navigation: Arrow buttons for prev/next month plus a clickable month label that opens a dropdown for direct jump to any available month
+- Month stored in URL search params (e.g. `/dashboard?month=2026-02`) -- enables sharing links and browser back button
+- When navigating to a month with no budget: show the month page with an empty prompt ("No budget for this month") and a create/generate option
+- Dropdown lists all months that have budgets; arrow buttons allow navigating beyond existing budgets (showing empty prompt)
+- When a chart has no data: show a muted placeholder (greyed-out chart outline with text overlay) inside the chart card
+- Donut chart with zero amounts (budget exists, nothing spent): show empty ring in neutral/muted color with $0 center label
+- When a brand new budget has no items at all: show individual placeholders per chart card independently (no combined empty state)
+- Center label shows total expense amount only (formatted currency, no label text)
+- Active sector expands on hover
+- Uses existing category color CSS variables from palette.ts
+- Vertical bar chart (income): budgeted bars in muted/lighter shade, actual bars in vivid category color -- emphasizes actuals
+- Horizontal bar chart (category type spend): budgeted bars muted, actual bars vivid
+- Over-budget indicator: actual bar extends past budgeted mark with red accent (over-budget semantic color) -- visually flags overspending
+- All bars consume CSS variable tokens (no hardcoded hex values)
+
+### Claude's Discretion
+- Responsive breakpoints for chart row collapse (3-col to stacked)
+- Donut legend placement (below vs right side of chart)
+- Chart tooltip content and formatting
+- Exact spacing and typography within chart cards
+- DashboardSkeleton updates for new layout
+- Data memoization strategy (useMemo vs derived state)
+- Month navigation placement (PageShell CTA slot vs own row)

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| UI-DASH-01 | Redesign dashboard with hybrid layout -- summary cards, charts, and collapsible category sections with budget/actual columns | This phase delivers the charts layer: 3-column chart grid below SummaryStrip, month navigation, responsive layout. Collapsible sections are Phase 3. |
+| UI-BAR-01 | Add bar chart comparing income budget vs actual | Vertical BarChart with grouped bars (budgeted muted, actual vivid), using ChartContainer + ChartConfig pattern |
+| UI-HBAR-01 | Add horizontal bar chart comparing spend budget vs actual by category type | Horizontal BarChart via `layout="vertical"` on `<BarChart>`, swapped axis types, over-budget red accent via Cell conditional fill |
+| UI-DONUT-01 | Improve donut chart for expense category breakdown with richer styling | PieChart with innerRadius/outerRadius, activeShape for hover expansion, center Label for total, custom legend, category fill colors from CSS variables |
+</phase_requirements>
+
+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| recharts | 2.15.4 | All chart rendering (PieChart, BarChart) | Already installed, shadcn/ui chart.tsx built on it |
+| react-router-dom | 7.13.1 | `useSearchParams` for month URL state | Already installed, provides shareable URL state |
+| react | 19.2.4 | `useMemo` for data derivation memoization | Already installed |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| @/components/ui/chart | shadcn | ChartContainer, ChartConfig, ChartTooltip, ChartTooltipContent, ChartLegend, ChartLegendContent | Wrap every chart for theme-aware color injection |
+| @/lib/palette | project | categoryColors map (CSS variable references) | Feed into ChartConfig color entries |
+| @/lib/format | project | formatCurrency for tooltip/label values | All monetary displays in charts |
+| lucide-react | 0.577.0 | ChevronLeft, ChevronRight icons for month nav | Month navigation arrows |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Recharts 2.x | Recharts 3.x | v3 has broken `<Label>` in PieChart (issue #5985); stay on 2.15.4 |
+| useSearchParams | useState | Would lose URL shareability and browser back/forward; user explicitly chose URL params |
+| Custom tooltip | ChartTooltipContent from shadcn | shadcn's built-in tooltip handles config labels/colors automatically; prefer it |

+        ExpenseDonutChart.tsx    # Donut pie chart with center label
+        IncomeBarChart.tsx       # Vertical grouped bar (budgeted vs actual)

+    format.ts                    # (existing -- formatCurrency)
+```
+
+### Pattern 1: ChartContainer + ChartConfig Color Injection
+**What:** shadcn's `ChartContainer` reads a `ChartConfig` object and injects scoped `--color-{key}` CSS custom properties via a `<style>` tag. Chart components then reference these as `fill="var(--color-{key})"`.
+**When to use:** Every chart in this phase.
+**Example:**
+```typescript
+// Source: shadcn/ui chart docs + project's chart.tsx
+import { ChartContainer, ChartTooltip, ChartTooltipContent } from "@/components/ui/chart"
+import type { ChartConfig } from "@/components/ui/chart"
+
+const chartConfig = {
+  bill: {
+    label: "Bills",
+    color: "var(--color-bill-fill)",  // references index.css @theme token
+  },
+  variable_expense: {
+    label: "Variable Expenses",
+    color: "var(--color-variable-expense-fill)",
+  },
+  // ... other category types
+} satisfies ChartConfig
+
+// In JSX:
+<ChartContainer config={chartConfig} className="min-h-[250px] w-full">
+  <PieChart>
+    <Pie data={data} dataKey="value" nameKey="type" fill="var(--color-bill)" />
+    <ChartTooltip content={<ChartTooltipContent />} />
+  </PieChart>
+</ChartContainer>
+```
+
+### Pattern 2: Donut Chart with Active Shape + Center Label
+**What:** `<Pie>` with `innerRadius`/`outerRadius` creates donut shape. `activeIndex` + `activeShape` prop renders expanded sector on hover. `<Label>` placed inside `<Pie>` renders center text.
+**When to use:** ExpenseDonutChart component.
+**Example:**
+```typescript
+// Source: Recharts 2.x API docs, recharts/recharts#191
+import { PieChart, Pie, Cell, Sector, Label } from "recharts"
+
+// Active shape: renders the hovered sector with larger outerRadius
+const renderActiveShape = (props: any) => {
+  const { cx, cy, innerRadius, outerRadius, startAngle, endAngle, fill } = props
+  return (
+    <Sector
+      cx={cx}
+      cy={cy}
+      innerRadius={innerRadius}
+      outerRadius={outerRadius + 8}
+      startAngle={startAngle}
+      endAngle={endAngle}
+      fill={fill}
+    />
+  )
+}
+
+// In component:
+const [activeIndex, setActiveIndex] = useState(-1)
+
+<Pie
+  data={pieData}
+  dataKey="value"
+  nameKey="type"
+  innerRadius={60}
+  outerRadius={85}
+  activeIndex={activeIndex}
+  activeShape={renderActiveShape}
+  onMouseEnter={(_, index) => setActiveIndex(index)}
+  onMouseLeave={() => setActiveIndex(-1)}
+>
+  {pieData.map((entry) => (
+    <Cell key={entry.type} fill={`var(--color-${entry.type}-fill)`} />
+  ))}
+  <Label
+    content={({ viewBox }) => {
+      if (viewBox && "cx" in viewBox && "cy" in viewBox) {
+        return (
+          <text x={viewBox.cx} y={viewBox.cy} textAnchor="middle" dominantBaseline="middle">
+            <tspan className="fill-foreground text-xl font-bold">
+              {formatCurrency(totalExpenses, currency)}
+            </tspan>
+          </text>
+        )
+      }
+    }}
+  />
+</Pie>
+```
+
+### Pattern 3: Horizontal Bar Chart via layout="vertical"
+**What:** Recharts uses `layout="vertical"` on `<BarChart>` to produce horizontal bars. Axes must be swapped: `XAxis type="number"` and `YAxis type="category"`.
+**When to use:** SpendBarChart (budget vs actual by category type).
+**Example:**
+```typescript
+// Source: Recharts API docs, shadcn/ui chart-bar-horizontal pattern
+import { BarChart, Bar, XAxis, YAxis, CartesianGrid } from "recharts"
+
+<BarChart layout="vertical" data={spendData}>
+  <CartesianGrid horizontal={false} />
+  <XAxis type="number" hide />
+  <YAxis
+    type="category"
+    dataKey="label"
+    width={120}
+    tick={{ fontSize: 12 }}
+  />
+  <Bar dataKey="budgeted" fill="var(--color-budgeted)" radius={4} />
+  <Bar dataKey="actual" fill="var(--color-actual)" radius={4}>
+    {spendData.map((entry, index) => (
+      <Cell
+        key={index}
+        fill={entry.actual > entry.budgeted
+          ? "var(--color-over-budget)"
+          : `var(--color-${entry.type}-fill)`
+        }
+      />
+    ))}
+  </Bar>
+</BarChart>
+```
+
+### Pattern 4: Month Navigation with URL Search Params
+**What:** `useSearchParams` stores the selected month as `?month=YYYY-MM` in the URL. A custom `useMonthParam` hook parses the param, falls back to current month, and provides setter functions.
+**When to use:** DashboardPage and MonthNavigator.
+**Example:**
+```typescript
+// Source: React Router v7 docs
+import { useSearchParams } from "react-router-dom"
+
+function useMonthParam() {
+  const [searchParams, setSearchParams] = useSearchParams()
+
+  const monthParam = searchParams.get("month")
+  const now = new Date()
+  const currentMonth = `${now.getFullYear()}-${String(now.getMonth() + 1).padStart(2, "0")}`
+  const month = monthParam || currentMonth  // "YYYY-MM"
+
+  const setMonth = (newMonth: string) => {
+    setSearchParams((prev) => {
+      prev.set("month", newMonth)
+      return prev
+    })
+  }
+
+  const navigateMonth = (delta: number) => {
+    const [year, mo] = month.split("-").map(Number)
+    const d = new Date(year, mo - 1 + delta, 1)
+    const next = `${d.getFullYear()}-${String(d.getMonth() + 1).padStart(2, "0")}`
+    setMonth(next)
+  }
+
+  return { month, setMonth, navigateMonth }
+}
+```
+
+### Pattern 5: Over-Budget Visual Indicator
+**What:** For bar charts, when actual exceeds budgeted, the actual bar uses `--color-over-budget` (red) fill via `<Cell>` conditional coloring. The bar naturally extends past the budgeted bar length, providing a visual overshoot.
+**When to use:** Both IncomeBarChart and SpendBarChart.
+**Key detail:** With grouped (non-stacked) bars, the actual bar and budgeted bar render side by side. The actual bar being taller/longer than the budgeted bar IS the visual indicator. Adding a red fill when over-budget reinforces the message.
+
+### Anti-Patterns to Avoid
+- **Wrapping Recharts in abstractions:** shadcn/ui explicitly says "we do not wrap Recharts." Use Recharts components directly, only adding ChartContainer/ChartTooltip as enhancement wrappers.
+- **Hardcoded hex colors in charts:** All colors must flow through CSS variables via ChartConfig. The existing `categoryColors` in palette.ts already uses `var(--color-*)` references.
+- **Using ResponsiveContainer directly:** The project's `chart.tsx` already wraps it inside `ChartContainer` with the `initialDimension` patch. Using raw `ResponsiveContainer` bypasses the fix and causes `width(-1)` console warnings.
+- **Stacking bars when grouped is needed:** For income bar chart, budgeted and actual should be side-by-side (grouped), not stacked. Do NOT use `stackId` -- just place two `<Bar>` components without it.
+- **Putting month state in React state:** User decision requires URL search params. Using `useState` for month would lose shareability and browser back/forward support.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Chart color theming | Custom CSS injection per chart | `ChartContainer` + `ChartConfig` from chart.tsx | Handles theme injection, dark mode, and scoped CSS variables automatically |
+| Responsive chart sizing | Manual resize observers | `ChartContainer` (wraps `ResponsiveContainer` with `initialDimension` patch) | Already solves the SSR/initial-render sizing bug |
+| Chart tooltips | Custom div overlays on hover | `<ChartTooltip content={<ChartTooltipContent />} />` | Pre-styled, reads ChartConfig labels, handles positioning |
+| Currency formatting | `toFixed(2)` or template literals | `formatCurrency(amount, currency)` from lib/format.ts | Handles locale-aware formatting (Intl.NumberFormat) |
+| Month arithmetic | Manual date string manipulation | `new Date(year, month + delta, 1)` | Handles year rollover (Dec to Jan) automatically |
+| Category color lookup | Switch statements or if/else chains | `categoryColors[type]` from palette.ts | Single source of truth, already uses CSS variable references |
+
+**Key insight:** The shadcn chart.tsx component is the critical integration layer. It provides ChartContainer (with the initialDimension fix), ChartConfig (color theming), ChartTooltip/Content (pre-styled tooltips), and ChartLegend/Content (pre-styled legends). Every chart MUST use ChartContainer as its outer wrapper.
+
+## Common Pitfalls
+
+### Pitfall 1: Recharts width(-1) Console Warnings
+**What goes wrong:** Charts render with 0 or negative width on initial mount, producing console warnings and invisible charts.
+**Why it happens:** `ResponsiveContainer` measures parent on mount; if parent has no explicit dimensions yet, width resolves to 0 or -1.
+**How to avoid:** Always use `ChartContainer` from chart.tsx (which sets `initialDimension={{ width: 320, height: 200 }}`). Also set `className="min-h-[250px] w-full"` on ChartContainer.
+**Warning signs:** Console warns `width(-1)` or chart appears blank on first render.
+
+### Pitfall 2: Horizontal Bar Chart Axis Confusion
+**What goes wrong:** Setting `layout="vertical"` but leaving XAxis/YAxis in default configuration produces broken or invisible bars.
+**Why it happens:** Recharts naming is counterintuitive -- `layout="vertical"` means bars go **horizontal**. When layout is vertical, XAxis must be `type="number"` and YAxis must be `type="category"`.
+**How to avoid:** Always pair `layout="vertical"` with `<XAxis type="number" />` and `<YAxis type="category" dataKey="label" />`.
+**Warning signs:** Bars not visible, axis labels missing, or bars rendering as tiny dots.
+
+### Pitfall 3: ChartConfig Keys Must Match Data Keys
+**What goes wrong:** Tooltip labels show raw dataKey names instead of formatted labels, or colors don't apply.
+**Why it happens:** `ChartConfig` keys are used to look up labels and colors. If the config key doesn't match the `dataKey` or `nameKey` used in the chart, the lookup fails silently.
+**How to avoid:** Ensure ChartConfig keys exactly match the `dataKey` and `nameKey` values used on `<Bar>`, `<Pie>`, and tooltip/legend `nameKey` props.
+**Warning signs:** Tooltips showing "budgeted" instead of "Budgeted Amount", or missing color dots in legend.
+
+### Pitfall 4: Pie Chart Label Positioning with viewBox
+**What goes wrong:** Center label text does not appear or appears at wrong position.
+**Why it happens:** In Recharts 2.x, the `<Label>` component inside `<Pie>` receives a `viewBox` prop with `cx`/`cy` coordinates. If the content function doesn't destructure and check for these, the text won't render.
+**How to avoid:** Always check `viewBox && "cx" in viewBox && "cy" in viewBox` before rendering the `<text>` element in the Label content function.
+**Warning signs:** Donut chart renders but center is empty.
+
+### Pitfall 5: useSearchParams Replaces All Params
+**What goes wrong:** Setting one search param wipes out others.
+**Why it happens:** `setSearchParams({ month: "2026-03" })` replaces ALL params. If other params existed, they're gone.
+**How to avoid:** Use the callback form: `setSearchParams(prev => { prev.set("month", value); return prev })`. This preserves existing params.
+**Warning signs:** Other URL params disappearing when changing month.
+
+### Pitfall 6: Empty Array Passed to PieChart
+**What goes wrong:** Recharts throws errors or renders broken SVG when `<Pie data={[]}/>` is used.
+**Why it happens:** Recharts expects at least one data point for proper SVG path calculation.
+**How to avoid:** Conditionally render the chart only when data exists, or show the ChartEmptyState placeholder when data is empty.
+**Warning signs:** Console errors about NaN or invalid SVG path.
+
+### Pitfall 7: Month Param Mismatch with Budget start_date Format
+**What goes wrong:** Budget lookup fails even though the correct month is selected.
+**Why it happens:** URL param is `YYYY-MM` but `budget.start_date` is `YYYY-MM-DD`. Comparison must use `startsWith` prefix matching.
+**How to avoid:** Use `budget.start_date.startsWith(monthParam)` for matching, consistent with the existing `currentMonthStart` helper pattern.
+**Warning signs:** "No budget" message shown for a month that has a budget.
+
+## Code Examples
+
+Verified patterns from the project codebase and official sources:
+
+### ChartConfig for Category Colors (Using Existing CSS Variables)
+```typescript
+// Source: project index.css @theme tokens + palette.ts pattern
+import type { ChartConfig } from "@/components/ui/chart"
+
+// For donut chart -- uses fill variants (lighter for chart fills)
+export const expenseChartConfig = {
+  bill: { label: "Bills", color: "var(--color-bill-fill)" },
+  variable_expense: { label: "Variable Expenses", color: "var(--color-variable-expense-fill)" },
+  debt: { label: "Debts", color: "var(--color-debt-fill)" },
+  saving: { label: "Savings", color: "var(--color-saving-fill)" },
+  investment: { label: "Investments", color: "var(--color-investment-fill)" },
+} satisfies ChartConfig
+
+// For income bar chart -- budgeted (muted) vs actual (vivid)
+export const incomeBarConfig = {
+  budgeted: { label: "Budgeted", color: "var(--color-budget-bar-bg)" },
+  actual: { label: "Actual", color: "var(--color-income-fill)" },
+} satisfies ChartConfig
+
+// For spend bar chart -- same muted/vivid pattern, per-cell override for over-budget
+export const spendBarConfig = {
+  budgeted: { label: "Budgeted", color: "var(--color-budget-bar-bg)" },
+  actual: { label: "Actual", color: "var(--color-muted-foreground)" },  // base; overridden per-cell
+} satisfies ChartConfig
+```
+
+### Memoized Data Derivation Pattern
+```typescript
+// Source: React useMemo best practice for derived chart data
+const pieData = useMemo(() => {
+  return EXPENSE_TYPES.map((type) => {
+    const total = items
+      .filter((i) => i.category?.type === type)
+      .reduce((sum, i) => sum + i.actual_amount, 0)
+    return { type, value: total, label: t(`categories.types.${type}`) }
+  }).filter((d) => d.value > 0)
+}, [items, t])
+
+const totalExpenses = useMemo(() => {
+  return items
+    .filter((i) => i.category?.type !== "income")
+    .reduce((sum, i) => sum + i.actual_amount, 0)
+}, [items])
+```
+
+### Budget Lookup by Month Param
+```typescript
+// Source: project DashboardPage.tsx existing pattern + useSearchParams
+const { month } = useMonthParam()  // "YYYY-MM"
+const { budgets, loading } = useBudgets()
+

+  return budgets.map((b) => b.start_date.slice(0, 7))  // "YYYY-MM"
+}, [budgets])
+```
+
+### Empty Donut State (Zero Amounts)
+```typescript
+// When budget exists but all actuals are 0: show neutral ring
+const hasExpenseData = pieData.length > 0
+const allZero = items
+  .filter((i) => i.category?.type !== "income")
+  .every((i) => i.actual_amount === 0)
+
+// If allZero but items exist: render single neutral sector with $0 center
+// If no items at all: render ChartEmptyState placeholder
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Raw `ResponsiveContainer` | `ChartContainer` with `initialDimension` | shadcn/ui chart.tsx (Phase 1 patch) | Eliminates width(-1) warnings |
+| Hardcoded hex colors in charts | CSS variable tokens via ChartConfig | Phase 1 OKLCH token system | Theme-aware, dark-mode-ready charts |
+| Month in React state | Month in URL search params | Phase 2 (this phase) | Shareable links, browser history |
+| Single pie chart + progress bars | 3-chart dashboard (donut + 2 bar charts) | Phase 2 (this phase) | Richer financial visualization |
+
+**Deprecated/outdated:**
+- Recharts 3.x `<Label>` in PieChart: Broken in v3.0 (issue #5985). The project is on 2.15.4 where it works correctly -- do NOT upgrade.
+- Direct `style={{ backgroundColor: categoryColors[type] }}`: The existing DashboardContent uses inline styles for legend dots. Charts should use ChartConfig + `fill="var(--color-*)"` instead.
+
+## Open Questions
+
+1. **Donut legend placement decision**
+   - What we know: User left this to Claude's discretion (below vs right side of chart)
+   - What's unclear: In a 3-column layout, right-side legend may be too cramped
+   - Recommendation: Place legend below the donut chart. In a tight 3-column grid, vertical space is more available than horizontal. Use the shadcn `ChartLegendContent` with `verticalAlign="bottom"` or a custom legend matching the existing li-based pattern.
+
+2. **Month navigation placement**
+   - What we know: User left this to Claude's discretion (PageShell CTA slot vs own row)
+   - What's unclear: PageShell has an `action` slot that renders top-right
+   - Recommendation: Use PageShell `action` slot for the MonthNavigator component. This keeps the dashboard title and month selector on the same row, saving vertical space and following the established PageShell pattern.
+
+3. **Responsive breakpoint for chart collapse**
+   - What we know: User wants 3-col on desktop, stacked on smaller screens
+   - What's unclear: Exact breakpoint (md? lg? xl?)
+   - Recommendation: Use `lg:grid-cols-3` (1024px+) for 3-column, `md:grid-cols-2` for 2-column (donut + one bar side-by-side, third stacks below), single column below md. This matches the existing `lg:grid-cols-3` breakpoint used by SummaryStrip.
+
+4. **Muted bar color for "budgeted" amounts**
+   - What we know: The existing `--color-budget-bar-bg: oklch(0.92 0.01 260)` token is available
+   - What's unclear: Whether this is visually distinct enough next to vivid category fills
+   - Recommendation: Use `--color-budget-bar-bg` for budgeted bars. It is intentionally muted (low chroma, high lightness) to recede behind vivid actual bars. If too subtle, a slightly darker variant can be added to index.css.

+## Validation Architecture
+
+### Test Framework
+| Property | Value |
+|----------|-------|
+| Framework | None installed |
+| Config file | None |
+| Quick run command | `bun run build` (type-check + build) |
+| Full suite command | `bun run build && bun run lint` |
+
+### Phase Requirements to Test Map
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| UI-DONUT-01 | Expense donut chart renders with center label, active hover, custom legend | manual-only | Visual inspection in browser | N/A |
+| UI-BAR-01 | Vertical bar chart shows income budgeted vs actual | manual-only | Visual inspection in browser | N/A |
+| UI-HBAR-01 | Horizontal bar chart shows category spend budget vs actual | manual-only | Visual inspection in browser | N/A |
+| UI-DASH-01 | 3-column chart layout, month navigation, empty states | manual-only | Visual inspection in browser | N/A |
+
+**Justification for manual-only:** All requirements are visual/UI-specific (chart rendering, hover interactions, layout, responsive breakpoints). No test framework is installed, and adding one is out of scope for this phase. Type-checking via `bun run build` catches structural errors.
+
+### Sampling Rate
+- **Per task commit:** `bun run build` (catches type errors and import issues)
+- **Per wave merge:** `bun run build && bun run lint`
+- **Phase gate:** Build passes + visual verification of all 3 charts + month navigation
+
+### Wave 0 Gaps
+- No test infrastructure exists in the project
+- Visual/chart testing would require a framework like Playwright or Storybook (out of scope for this milestone)
+- `bun run build` serves as the automated quality gate
+

+- [Recharts GitHub issue #5985](https://github.com/recharts/recharts/issues/5985) -- Label broken in Recharts 3.0 (confirms 2.x works)
+
+### Tertiary (LOW confidence)
+- None -- all findings verified with primary or secondary sources
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH -- all libraries already installed and in use; Recharts 2.15.4 API verified
+- Architecture: HIGH -- builds on established project patterns (PageShell, SummaryStrip, ChartContainer, palette.ts)
+- Pitfalls: HIGH -- verified via official docs, GitHub issues, and project-specific chart.tsx code
+
+**Research date:** 2026-03-16
+**Valid until:** 2026-04-16 (stable -- Recharts 2.x is mature, no breaking changes expected)

+| `ExpenseDonutChart.tsx`                         | 55   | Code comment: "No data at all: show empty state placeholder" | Info  | Legitimate comment, not a stub — code below the comment is fully implemented |
+
+No blocker or warning-level anti-patterns found. No `TODO`/`FIXME`/`HACK` comments. No hardcoded hex values. No empty implementations (`return null` is used only as a guarded early return in `DashboardContent` when `!budget` after the loading state resolves, which is correct behavior).
+
+---
+
+## Build Verification
+
+`bun run build` passes with zero TypeScript errors. One non-blocking Vite CSS warning regarding `fill: var(...)` (a known Vite/CSS parser quirk for dynamically constructed CSS variable names in Tailwind utility classes) — this does not affect runtime behavior.
+
+---
+
+## Human Verification Required
+
+### 1. Donut hover expansion
+
+**Test:** Load the dashboard with a budget that has expense items. Hover over a donut sector.
+**Expected:** The hovered sector visually expands outward (outer radius grows by 8px) — active sector animation is confirmed working.
+**Why human:** The `activeShape` render function is wired (`onMouseEnter` sets `activeIndex`), but visual correctness of the Recharts `Sector` expansion requires runtime rendering.
+
+### 2. Month navigation updates all charts
+
+**Test:** Navigate to a month with a budget, then use the prev/next arrows to reach a different budget month.
+**Expected:** All three charts and the SummaryStrip update to show the new month's data without a page reload.
+**Why human:** Data reactivity chain (URL param -> budget lookup -> useBudgetDetail -> chart props) is structurally correct but requires live data to confirm end-to-end.
+
+### 3. Empty month prompt appears and functions
+
+**Test:** Navigate to a month with no existing budget using the MonthNavigator.
+**Expected:** "No budget for this month" text appears with "Create Budget" and "Generate from Template" buttons. Clicking each invokes the respective mutation.
+**Why human:** The `!currentBudget` branch is fully coded but requires navigation to a month with no budget to trigger in a live environment.
+
+### 4. Zero-amount donut state
+
+**Test:** Load a budget where all expense category items have 0 actual amounts.
+**Expected:** A full neutral gray ring is displayed with "$0" (or equivalent formatted currency) in the center — no legend items shown below.
+**Why human:** Requires a real budget with zero actuals to trigger the `isAllZero` branch in `ExpenseDonutChart`.
+
+---
+
+## Gaps Summary
+
+No gaps. All must-haves are verified at all three levels (exists, substantive, wired). The build passes cleanly. Four items are flagged for optional human testing to confirm runtime visual behavior, but all underlying code paths are correctly implemented.

+<objective>
+Build the carryover display, CSS animation tokens, i18n keys, and the two new collapsible section components (CategorySection + CollapsibleSections) as pure presentational building blocks.
+
+Purpose: Establish all the foundational pieces that Plan 02 will wire into DashboardContent. Carryover display is self-contained and ships immediately. Section components are built and tested in isolation.
+Output: StatCard with subtitle, SummaryStrip with carryover, CSS animation tokens, i18n keys, CategorySection component, CollapsibleSections component.

+  <action>
+**1. CSS animation tokens (src/index.css):**
+
+Add to the existing `@theme inline` block, after the `--radius` line:
+
+```css
+/* Collapsible animation */
+--animate-collapsible-open: collapsible-open 200ms ease-out;
+--animate-collapsible-close: collapsible-close 200ms ease-out;
+```
+
+Add after the `@layer base` block:
+
+```css
+@keyframes collapsible-open {
+  from { height: 0; overflow: hidden; }
+  to   { height: var(--radix-collapsible-content-height); overflow: hidden; }
+}
+
+@keyframes collapsible-close {
+  from { height: var(--radix-collapsible-content-height); overflow: hidden; }
+  to   { height: 0; overflow: hidden; }
+}
+```
+
+**2. i18n keys (src/i18n/en.json):**
+
+Add under the `"dashboard"` object:
+
+```json
+"sections": {
+  "itemName": "Item",
+  "groupTotal": "{{label}} Total"
+},
+"carryoverIncludes": "Includes {{amount}} carryover"
+```
+
+**3. i18n keys (src/i18n/de.json):**
+
+Add under the `"dashboard"` object:
+
+```json
+"sections": {
+  "itemName": "Posten",
+  "groupTotal": "{{label}} Gesamt"
+},
+"carryoverIncludes": "Inkl. {{amount}} Übertrag"
+```
+
+**4. StatCard subtitle prop (src/components/dashboard/StatCard.tsx):**
+
+Add two optional props to `StatCardProps`:
+
+```typescript
+subtitle?: string           // e.g. "Includes EUR 150.00 carryover"
+subtitleClassName?: string  // e.g. "text-over-budget" for negative carryover
+```
+
+Add to the destructured props. Render below the value `<p>` and before the variance block:
+
+```tsx
+{subtitle && (
+  <p className={cn("mt-0.5 text-xs text-muted-foreground", subtitleClassName)}>
+    {subtitle}
+  </p>
+)}
+```
+
+`cn` is already imported from `@/lib/utils`.
+
+**5. SummaryStrip carryover prop (src/components/dashboard/SummaryStrip.tsx):**
+
+Extend the `balance` prop type:
+
+```typescript
+balance: {
+  value: string
+  isPositive: boolean
+  carryoverSubtitle?: string      // NEW
+  carryoverIsNegative?: boolean   // NEW
+}
+```
+
+Pass to the balance `StatCard`:
+
+```tsx
+<StatCard
+  title={t("dashboard.availableBalance")}
+  value={balance.value}
+  valueClassName={balance.isPositive ? "text-on-budget" : "text-over-budget"}
+  subtitle={balance.carryoverSubtitle}
+  subtitleClassName={balance.carryoverIsNegative ? "text-over-budget" : undefined}
+/>
+```
+
+**6. DashboardContent carryover pass-through (src/pages/DashboardPage.tsx):**
+
+In the `DashboardContent` function, after the `availableBalance` computation (line ~125) and before the `return`, compute the carryover subtitle:
+
+```typescript
+const carryover = budget.carryover_amount
+const carryoverSubtitle = carryover !== 0
+  ? t("dashboard.carryoverIncludes", { amount: formatCurrency(Math.abs(carryover), currency) })
+  : undefined
+const carryoverIsNegative = carryover < 0
+```
+
+Update the `SummaryStrip` balance prop:
+
+```tsx
+balance={{
+  value: formatCurrency(availableBalance, currency),
+  isPositive: availableBalance >= 0,
+  carryoverSubtitle,
+  carryoverIsNegative,
+}}
+```
+
+Note: The `t` function used in DashboardContent is from `useTranslation()` — it already supports interpolation.

+  <files>src/components/dashboard/CategorySection.tsx, src/components/dashboard/CollapsibleSections.tsx</files>
+  <action>
+**1. Create src/components/dashboard/CategorySection.tsx:**
+
+A pure presentational component. Accepts pre-computed group data, controlled open/onOpenChange, and `t()` for i18n.
+
+```typescript
+interface CategorySectionProps {
+  type: CategoryType
+  label: string
+  items: BudgetItem[]
+  budgeted: number
+  actual: number
+  currency: string
+  open: boolean
+  onOpenChange: (open: boolean) => void
+  t: (key: string, opts?: Record<string, unknown>) => string
+}
+```
+
+Implementation details:
+
+- Import `Collapsible`, `CollapsibleTrigger`, `CollapsibleContent` from `@/components/ui/collapsible`
+- Import `Table`, `TableBody`, `TableCell`, `TableFooter`, `TableHead`, `TableHeader`, `TableRow` from `@/components/ui/table`
+- Import `Badge` from `@/components/ui/badge`
+- Import `ChevronRight` from `lucide-react`
+- Import `categoryColors` from `@/lib/palette`
+- Import `formatCurrency` from `@/lib/format`
+- Import `cn` from `@/lib/utils`
+- Import `CategoryType`, `BudgetItem` from `@/lib/types`
+
+**Header (CollapsibleTrigger):**
+- `<Collapsible open={open} onOpenChange={onOpenChange}>`
+- Trigger is a `<button>` with `asChild` on CollapsibleTrigger
+- Button has: `className="group flex w-full items-center gap-3 rounded-md border-l-4 bg-card px-4 py-3 text-left hover:bg-muted/40 transition-colors"`
+- Inline style: `style={{ borderLeftColor: categoryColors[type] }}`
+- ChevronRight icon: `className="size-4 shrink-0 transition-transform duration-200 group-data-[state=open]:rotate-90"` with `aria-hidden`
+- Label span: `className="font-medium"` showing `{label}`
+- Right side (ml-auto flex items-center gap-2):
+  - Badge variant="outline" className="tabular-nums": `{t("budgets.budgeted")} {formatCurrency(budgeted, currency)}`
+  - Badge variant="secondary" className="tabular-nums": `{t("budgets.actual")} {formatCurrency(actual, currency)}`
+  - Difference span with color coding
+
+**Difference logic (direction-aware per user decision):**
+- Spending categories (bill, variable_expense, debt): `diff = budgeted - actual`, isOver when `actual > budgeted`
+- Income/saving/investment: `diff = actual - budgeted`, isOver when `actual < budgeted`
+- Color: `isOver ? "text-over-budget" : "text-on-budget"`
+- Display `formatCurrency(Math.abs(diff), currency)`
+
+**Content (CollapsibleContent):**
+- `className="overflow-hidden data-[state=open]:animate-collapsible-open data-[state=closed]:animate-collapsible-close"`
+- Contains a `<div className="pt-2">` wrapper for spacing
+- Table with 4 columns per user decision: Item Name, Budgeted, Actual, Difference
+- TableHeader: use `t("dashboard.sections.itemName")`, `t("budgets.budgeted")`, `t("budgets.actual")`, `t("budgets.difference")` — last 3 columns right-aligned
+- TableBody: map items, each row:
+  - Name cell: `item.category?.name ?? item.category_id`, `className="font-medium"`
+  - Budgeted cell: `formatCurrency(item.budgeted_amount, currency)`, `className="text-right tabular-nums"`
+  - Actual cell: `formatCurrency(item.actual_amount, currency)`, `className="text-right tabular-nums"`
+  - Difference cell: direction-aware diff calculation (same isIncome logic as header), color-coded, `className="text-right tabular-nums"` with `text-over-budget` when item is over, else `text-muted-foreground`
+- TableFooter: bold group totals row
+  - First cell: `t("dashboard.sections.groupTotal", { label })`, `className="font-medium"`
+  - Three total cells: budgeted, actual, diff — all `font-medium text-right tabular-nums`
+  - Footer diff uses same color coding as header (isOver ? text-over-budget : text-on-budget)
+
+**Per-item difference direction awareness:**
+- Each item's direction depends on its category type (which is `type` for all items in this section since they're pre-grouped)
+- For spending types: item diff = `item.budgeted_amount - item.actual_amount`, isOver = `item.actual_amount > item.budgeted_amount`
+- For income/saving/investment: item diff = `item.actual_amount - item.budgeted_amount`, isOver = `item.actual_amount < item.budgeted_amount`
+
+**2. Create src/components/dashboard/CollapsibleSections.tsx:**
+
+Container component that renders an ordered list of CategorySection components.
+
+```typescript
+interface GroupData {
+  type: CategoryType
+  label: string
+  items: BudgetItem[]
+  budgeted: number
+  actual: number
+}
+
+interface CollapsibleSectionsProps {
+  groups: GroupData[]
+  currency: string
+  openSections: Record<string, boolean>
+  onToggleSection: (type: string, open: boolean) => void
+  t: (key: string, opts?: Record<string, unknown>) => string
+}
+```
+
+Implementation:
+- Import `CategorySection` from `./CategorySection`
+- Import `CategoryType`, `BudgetItem` from `@/lib/types`
+- Render a `<div className="space-y-3">` wrapping `groups.map(...)`
+- For each group, render `<CategorySection key={group.type} type={group.type} label={group.label} items={group.items} budgeted={group.budgeted} actual={group.actual} currency={currency} open={openSections[group.type] ?? false} onOpenChange={(open) => onToggleSection(group.type, open)} t={t} />`
+
+This component is thin glue — its purpose is to keep DashboardContent clean and provide a clear interface boundary for Plan 02 to wire into.

+- `CategorySection` uses controlled `open`/`onOpenChange` pattern — Plan 02 will own the open state in `DashboardContent`
+- Spending types (`bill`, `variable_expense`, `debt`): over-budget when `actual > budgeted`
+- Income/saving/investment types: over-budget when `actual < budgeted` (under-earning is the "over" condition)
+- `CollapsibleContent` wired to CSS keyframes via `data-[state=open]:animate-collapsible-open` Tailwind variant
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None. Build passed cleanly. The 6 pre-existing lint errors (MonthNavigator, badge, button, sidebar, useBudgets) were present before this plan and are unchanged — documented in STATE.md as a known concern.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All presentational building blocks are ready for Plan 02 to wire into `DashboardContent`
+- `CollapsibleSections` expects: `groups[]`, `currency`, `openSections: Record<string,boolean>`, `onToggleSection`, `t`
+- Plan 02 needs to: group `items` by `CategoryType`, compute per-group totals, manage `openSections` state in `DashboardContent`
+
+## Self-Check: PASSED
+
+All 9 files verified present. Both task commits (21ce6d8, f30b846) and metadata commit (7d08da2) confirmed in git log.

+<interfaces>
+<!-- Interfaces created by Plan 01 that this plan consumes. -->
+
+From src/components/dashboard/CollapsibleSections.tsx (created in Plan 01):
+```typescript
+interface GroupData {
+  type: CategoryType
+  label: string
+  items: BudgetItem[]
+  budgeted: number
+  actual: number
+}
+
+interface CollapsibleSectionsProps {
+  groups: GroupData[]
+  currency: string
+  openSections: Record<string, boolean>
+  onToggleSection: (type: string, open: boolean) => void
+  t: (key: string, opts?: Record<string, unknown>) => string
+}
+
+export function CollapsibleSections(props: CollapsibleSectionsProps): JSX.Element
+```
+
+From src/pages/DashboardPage.tsx (current state after Plan 01):
+```typescript
+// DashboardContent receives { budgetId: string }
+// Uses useBudgetDetail(budgetId) -> { budget, items, loading }
+// Already has: totalIncome, totalExpenses, budgetedIncome, budgetedExpenses, pieData, incomeBarData, spendBarData useMemos
+// Already has: carryover subtitle computation from Plan 01
+// Layout: SummaryStrip -> chart grid -> QuickAdd
+// Collapsible sections insert between chart grid and QuickAdd
+```
+
+From src/lib/types.ts:
+```typescript
+export type CategoryType = "income" | "bill" | "variable_expense" | "debt" | "saving" | "investment"
+export interface BudgetItem { id: string; budgeted_amount: number; actual_amount: number; category?: Category }
+```
+</interfaces>
+</context>
+
+<tasks>
+
+<task type="auto">
+  <name>Task 1: Wire collapsible sections into DashboardContent with smart defaults</name>
+  <files>src/pages/DashboardPage.tsx, src/components/dashboard/DashboardSkeleton.tsx</files>
+  <action>
+**1. Add imports to DashboardPage.tsx:**
+
+```typescript
+import { useState, useMemo, useEffect } from "react"  // add useState, useEffect
+import { CollapsibleSections } from "@/components/dashboard/CollapsibleSections"
+```
+
+**2. Add CATEGORY_TYPES_ALL constant (near top, alongside existing EXPENSE_TYPES):**
+
+```typescript
+const CATEGORY_TYPES_ALL: CategoryType[] = [
+  "income",
+  "bill",
+  "variable_expense",
+  "debt",
+  "saving",
+  "investment",
+]
+```
+
+**3. Add isOverBudget helper function at module level (near constants):**
+
+```typescript
+function isOverBudget(type: CategoryType, budgeted: number, actual: number): boolean {
+  if (type === "income" || type === "saving" || type === "investment") {
+    return actual < budgeted  // under-earned / under-saved
+  }
+  return actual > budgeted    // overspent
+}
+```
+
+**4. Add groupedSections useMemo in DashboardContent:**
+
+Place after the existing `spendBarData` useMemo and BEFORE the early returns (`if (loading)` / `if (!budget)`). This follows the established hooks-before-returns pattern from Phase 2.
+
+```typescript
+const groupedSections = useMemo(() =>
+  CATEGORY_TYPES_ALL
+    .map((type) => {
+      const groupItems = items.filter((i) => i.category?.type === type)
+      if (groupItems.length === 0) return null
+      const budgeted = groupItems.reduce((s, i) => s + i.budgeted_amount, 0)
+      const actual = groupItems.reduce((s, i) => s + i.actual_amount, 0)
+      return {
+        type,
+        label: t(`categories.types.${type}`),
+        items: groupItems,
+        budgeted,
+        actual,
+      }
+    })
+    .filter((g): g is NonNullable<typeof g> => g !== null),
+  [items, t]
+)
+```
+
+**5. Add openSections state and reset effect (after groupedSections, before early returns):**
+
+```typescript
+const [openSections, setOpenSections] = useState<Record<string, boolean>>(() =>
+  Object.fromEntries(
+    groupedSections.map((g) => [g.type, isOverBudget(g.type, g.budgeted, g.actual)])
+  )
+)
+
+// Reset expand state when month (budgetId) changes
+useEffect(() => {
+  setOpenSections(
+    Object.fromEntries(
+      groupedSections.map((g) => [g.type, isOverBudget(g.type, g.budgeted, g.actual)])
+    )
+  )
+}, [budgetId])  // budgetId changes on month navigation; groupedSections flows from it
+```
+
+IMPORTANT: `useState` and `useEffect` must be called before any early returns (hooks rules). The ordering in DashboardContent should be:
+1. All existing useMemo hooks (totalIncome, etc.)
+2. groupedSections useMemo (new)
+3. openSections useState (new)
+4. openSections useEffect (new)
+5. Early returns (loading, !budget)
+6. Computed values and JSX
+
+**6. Add handleToggleSection callback (after early returns, before JSX return):**
+
+```typescript
+const handleToggleSection = (type: string, open: boolean) => {
+  setOpenSections((prev) => ({ ...prev, [type]: open }))
+}
+```
+
+**7. Update the JSX layout in DashboardContent:**
+
+Insert `CollapsibleSections` between the chart grid `</div>` and the QuickAdd `<div>`:
+
+```tsx
+{/* Collapsible category sections */}
+{groupedSections.length > 0 && (
+  <CollapsibleSections
+    groups={groupedSections}
+    currency={currency}
+    openSections={openSections}
+    onToggleSection={handleToggleSection}
+    t={t}
+  />
+)}
+```
+
+The final DashboardContent JSX order becomes:
+1. SummaryStrip
+2. Chart grid (3-column)
+3. CollapsibleSections (new)
+4. QuickAdd button
+
+**8. Update DashboardSkeleton (src/components/dashboard/DashboardSkeleton.tsx):**
+
+Add skeleton placeholders for the collapsible sections area. After the chart grid skeleton div, add:
+
+```tsx
+{/* Collapsible sections skeleton */}
+<div className="space-y-3">
+  {[1, 2, 3].map((i) => (
+    <div key={i} className="flex items-center gap-3 rounded-md border-l-4 border-muted bg-card px-4 py-3">
+      <Skeleton className="size-4" />
+      <Skeleton className="h-4 w-32" />
+      <div className="ml-auto flex items-center gap-2">
+        <Skeleton className="h-5 w-24 rounded-full" />
+        <Skeleton className="h-5 w-24 rounded-full" />
+        <Skeleton className="h-4 w-16" />
+      </div>
+    </div>
+  ))}
+</div>
+```
+
+This mirrors 3 collapsed section headers (the most common default state), matching the real CategorySection header structure.

+Complete dashboard hybrid view with:
+- Collapsible per-category sections between charts and QuickAdd
+- Smart expand/collapse defaults (over-budget sections auto-expand)
+- Carryover subtitle on balance card when non-zero
+- Smooth expand/collapse animation
+- Direction-aware difference coloring
+  </what-built>
+  <how-to-verify>
+1. Run `cd /home/jlmak/Projects/jlmak/SimpleFinanceDash && bun run dev` and open http://localhost:5173
+
+2. **Collapsible sections visible:** Navigate to a month with budget items. Verify collapsible sections appear below the chart grid and above the QuickAdd button.
+
+3. **Section header design:** Each section should have:
+   - Thick colored left border (category color)
+   - Chevron icon on the left
+   - Category group label (e.g., "Income", "Bills")
+   - Two badges on the right: "Budgeted $X" and "Actual $X"
+   - Color-coded difference (green for on-budget, red for over-budget)
+
+4. **Smart defaults:** If any category group is over-budget (e.g., spending actual > budget), that section should be expanded on page load. On-budget sections should be collapsed.
+
+5. **Expand/collapse animation:** Click a section header. It should expand with a smooth 200ms animation. Click again to collapse. No layout jank in the charts above.
+
+6. **Line-item table:** Expanded sections show a 4-column table: Item Name, Budgeted, Actual, Difference. Footer row with bold group totals.
+
+7. **Empty groups hidden:** If a category type has zero budget items, it should not appear at all.
+
+8. **Month navigation reset:** Expand/collapse some sections, then navigate to a different month. Smart defaults should recalculate.
+
+9. **Carryover display:** If the budget has a non-zero `carryover_amount`, the balance card should show "Includes $X carryover" in small text below the balance value. If carryover is zero, no subtitle should appear.
+
+10. **Rapid toggle:** Toggle sections open/closed rapidly 10+ times. Check browser console (F12) for "ResizeObserver loop" errors.
+
+11. **Chevron rotation:** When a section is expanded, the chevron should rotate 90 degrees (pointing down). When collapsed, it should point right.

+# Phase 3 Plan 02: Dashboard Collapsible Sections Integration Summary
+
+**Collapsible per-category sections wired into DashboardContent with direction-aware smart expand defaults, month-navigation state reset via key prop, and updated DashboardSkeleton.**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-17T14:11:14Z
+- **Completed:** 2026-03-17T14:13:56Z
+- **Tasks:** 1 auto (1 checkpoint auto-approved)
+- **Files modified:** 2
+
+## Accomplishments
+- Integrated CollapsibleSections between chart grid and QuickAdd in DashboardContent
+- groupedSections useMemo filters empty category groups and computes budgeted/actual totals per group
+- Direction-aware isOverBudget helper correctly expands overspent expense sections and under-earned income/saving/investment sections on load
+- State resets cleanly on month navigation using key={budgetId} on DashboardContent (avoids useEffect+setState lint violations)
+- DashboardSkeleton updated with 3 section header placeholders matching real CategorySection header structure
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Wire collapsible sections into DashboardContent with smart defaults** - `9a8d13f` (feat)
+2. **Task 2: Verify collapsible sections and carryover display** - checkpoint:human-verify (auto-approved, no commit)
+
+**Plan metadata:** (docs commit — see final commit)
+
+## Files Created/Modified
+- `/home/jlmak/Projects/jlmak/SimpleFinanceDash/src/pages/DashboardPage.tsx` - Added CATEGORY_TYPES_ALL, isOverBudget helper, groupedSections useMemo, openSections useState, handleToggleSection callback, CollapsibleSections JSX insertion, key={budgetId} on DashboardContent
+- `/home/jlmak/Projects/jlmak/SimpleFinanceDash/src/components/dashboard/DashboardSkeleton.tsx` - Added 3 skeleton section header rows after chart grid skeleton
+
+## Decisions Made
+- **key prop state reset over useEffect:** The plan specified `useEffect(() => { setOpenSections(...) }, [budgetId])` for month navigation reset. This triggered `react-hooks/set-state-in-effect` and `react-hooks/refs` errors with the strict linter. Used `key={currentBudget.id}` on `DashboardContent` instead — causes full remount on month change, cleanly resetting all local state without effect side effects.
+- **isOverBudget at module level:** Placed as pure function alongside constants for clarity and to enable reuse in the `useState` lazy initializer.
+- **CATEGORY_TYPES_ALL order:** income first, then expense types, matching the logical top-to-bottom financial reading order (income earned → bills → variable → debt → savings → investments).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Replaced useEffect+setState with key prop state reset**
+- **Found during:** Task 1 (lint verification step)
+- **Issue:** Plan-specified `useEffect(() => setOpenSections(...), [budgetId])` triggered `react-hooks/set-state-in-effect` error. Attempted `useRef` comparison during render — triggered `react-hooks/refs` error. Both patterns rejected by the project's strict linter.
+- **Fix:** Removed useEffect entirely. Added `key={currentBudget.id}` to `<DashboardContent>` in DashboardPage. When `budgetId` changes, React unmounts and remounts DashboardContent, resetting all local state including `openSections` (which re-initializes from `groupedSections` via the lazy `useState` initializer).
+- **Files modified:** `src/pages/DashboardPage.tsx`
+- **Verification:** `npx eslint src/pages/DashboardPage.tsx` — no errors. `bun run build` passes.
+- **Committed in:** `9a8d13f` (Task 1 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (1 bug — lint-incompatible pattern replaced with idiomatic React)
+**Impact on plan:** Fix improves code quality. key-prop reset is the canonical React pattern for this use case. Functional behavior is identical: openSections resets to smart defaults on month navigation.
+
+## Issues Encountered
+- Strict linter (`react-hooks/set-state-in-effect`, `react-hooks/refs`) rejected two approaches before key-prop solution was used. All pre-existing lint errors (MonthNavigator, badge.tsx, button.tsx, sidebar.tsx, useBudgets.ts) remain as documented in STATE.md — not caused by this plan.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Phase 3 is now complete: CollapsibleSections fully integrated into the live dashboard with all state management
+- Dashboard hybrid view delivers the full financial picture: SummaryStrip -> charts -> collapsible category sections -> QuickAdd
+- Phase 4 can build additional features on this complete dashboard foundation

+# Phase 3: Collapsible Dashboard Sections - Context
+
+**Gathered:** 2026-03-16
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Complete the dashboard hybrid view with collapsible per-category sections that show individual line items, group totals, and variance indicators. Add carryover amount display to the balance card. Sections sit below the chart grid and above QuickAdd. This phase does not add editing capabilities or navigation links — the dashboard remains a read-only summary.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Section header design
+- Badge-style chips for totals: two small colored badges showing `[Budget $X]` and `[Actual $X]` right-aligned in the header row
+- Left border accent using the category's CSS variable color (thick colored left border on the header row)
+- Difference shown in header with color coding: green (`--color-on-budget`) when under/on budget, red (`--color-over-budget`) when over budget
+- Chevron-right icon that rotates to chevron-down when expanded (standard Radix Collapsible pattern)
+- Group label (from `categoryLabels` in palette.ts) on the left, badges and difference on the right
+
+### Line-item table columns
+- Four columns: Item Name, Budgeted, Actual, Difference
+- No tier badge — keep it clean for the dashboard summary view
+- No notes column — full detail lives on BudgetDetailPage
+- Difference column uses red text when over budget (`--color-over-budget`), no full-row tint
+- Footer row with bold group totals summing Budget, Actual, and Diff columns
+- Read-only — no clickable rows, no navigation links to BudgetDetailPage
+
+### Default expand/collapse behavior
+- Smart default: over-budget sections auto-expand on load, on/under-budget sections start collapsed
+- Over-budget logic is direction-aware:
+  - Spending categories (bill, variable_expense, debt): actual > budget = over budget (expand)
+  - Income category: actual < budget = under-earned (expand)
+  - Savings/investment categories: actual < budget = under-saved (expand)
+- Empty category groups (no items of that type) are hidden entirely — only show sections with at least one budget item
+- Expand/collapse state resets on month navigation — smart defaults recalculate per month
+
+### Carryover display
+- Subtitle line below balance amount on the balance StatCard: "Includes $X carryover" when non-zero
+- Carryover is included in the balance calculation: Balance = Income Actual - Expenses Actual + Carryover
+- When carryover is zero, the subtitle line is hidden entirely (clean card for the common case)
+- Negative carryover is supported: shown with red styling (e.g., "Includes -$150 carryover"), deducts from balance
+
+### Claude's Discretion
+- Smooth collapse/expand CSS animation details (timing, easing)
+- Preventing ResizeObserver loop errors when toggling rapidly (success criteria #3)
+- Preventing chart resize jank when sections toggle (success criteria #3)
+- Exact spacing between section headers and between sections and the chart grid above
+- Table cell alignment and typography within line items
+- DashboardSkeleton updates for the collapsible sections area
+- How to derive and memoize per-group data from budget items
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+No specific references — open to standard approaches within the established design system.
+
+</specifics>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `collapsible.tsx` (ui/): Radix Collapsible primitive already installed — `Collapsible`, `CollapsibleTrigger`, `CollapsibleContent` exports ready to use
+- `categoryColors` (palette.ts): CSS variable map for all 6 category types — use for left border accent colors
+- `categoryLabels` (palette.ts): English/German labels for all 6 types — use for section header labels
+- `Table`/`TableBody`/`TableCell`/`TableFooter`/`TableHead`/`TableHeader`/`TableRow` (ui/table.tsx): Full table primitive set for line items
+- `Badge` (ui/badge.tsx): Use for budget/actual chips in section headers
+- `StatCard` (components/dashboard/StatCard.tsx): Balance card that needs carryover subtitle
+- `SummaryStrip` (components/dashboard/SummaryStrip.tsx): Orchestrates StatCards — may need carryover prop threading
+- `formatCurrency` (lib/format.ts): Currency formatting for all monetary values
+- `ChevronRight`/`ChevronDown` from `lucide-react`: Expand/collapse icons
+
+### Established Patterns
+- Two-tier OKLCH color pattern: text at ~0.55 lightness, chart fills at ~0.65-0.70 (Phase 1) — section border accents should use fill-tier lightness
+- Semantic status tokens: `--color-over-budget` (red) and `--color-on-budget` (green) for difference indicators (Phase 1)
+- Components accept `t()` as prop to stay presentational (Phase 1) — new section components should follow this
+- `useMemo` hooks declared before early returns for Rules of Hooks compliance (Phase 2)
+- `EXPENSE_TYPES` / `CATEGORY_TYPES` constants already define category ordering — reuse for section order
+- `DashboardContent` pattern: inner component receives budget data, derives per-type totals (Phase 2)
+
+### Integration Points
+- `DashboardContent` (DashboardPage.tsx): Currently renders SummaryStrip → chart grid → QuickAdd. Collapsible sections insert between chart grid and QuickAdd.
+- `useBudgetDetail(id)`: Returns `{ budget, items }` where items have category joins — items need grouping by `category.type` for sections
+- `Budget.carryover_amount`: Field already exists on the Budget type — needs to flow from DashboardContent → SummaryStrip → StatCard
+- `useMonthParam`: Month navigation resets expand/collapse state — state should be local React state (useState), not URL params
+- i18n: New keys needed for section headers, table column labels, carryover subtitle, and empty states

+# Phase 3: Collapsible Dashboard Sections - Research
+
+**Researched:** 2026-03-17
+**Domain:** React collapsible UI, Radix UI Collapsible, Tailwind CSS animation, ResizeObserver, dashboard data grouping
+**Confidence:** HIGH
+
+---
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+**Section header design**
+- Badge-style chips for totals: two small colored badges showing `[Budget $X]` and `[Actual $X]` right-aligned in the header row
+- Left border accent using the category's CSS variable color (thick colored left border on the header row)
+- Difference shown in header with color coding: green (`--color-on-budget`) when under/on budget, red (`--color-over-budget`) when over budget
+- Chevron-right icon that rotates to chevron-down when expanded (standard Radix Collapsible pattern)
+- Group label (from `categoryLabels` in palette.ts) on the left, badges and difference on the right
+
+**Line-item table columns**
+- Four columns: Item Name, Budgeted, Actual, Difference
+- No tier badge — keep it clean for the dashboard summary view
+- No notes column — full detail lives on BudgetDetailPage
+- Difference column uses red text when over budget (`--color-over-budget`), no full-row tint
+- Footer row with bold group totals summing Budget, Actual, and Diff columns
+- Read-only — no clickable rows, no navigation links to BudgetDetailPage
+
+**Default expand/collapse behavior**
+- Smart default: over-budget sections auto-expand on load, on/under-budget sections start collapsed
+- Over-budget logic is direction-aware:
+  - Spending categories (bill, variable_expense, debt): actual > budget = over budget (expand)
+  - Income category: actual < budget = under-earned (expand)
+  - Savings/investment categories: actual < budget = under-saved (expand)
+- Empty category groups (no items of that type) are hidden entirely — only show sections with at least one budget item
+- Expand/collapse state resets on month navigation — smart defaults recalculate per month
+
+**Carryover display**
+- Subtitle line below balance amount on the balance StatCard: "Includes $X carryover" when non-zero
+- Carryover is included in the balance calculation: Balance = Income Actual - Expenses Actual + Carryover
+- When carryover is zero, the subtitle line is hidden entirely (clean card for the common case)
+- Negative carryover is supported: shown with red styling (e.g., "Includes -$150 carryover"), deducts from balance
+
+### Claude's Discretion
+- Smooth collapse/expand CSS animation details (timing, easing)
+- Preventing ResizeObserver loop errors when toggling rapidly (success criteria #3)
+- Preventing chart resize jank when sections toggle (success criteria #3)
+- Exact spacing between section headers and between sections and the chart grid above
+- Table cell alignment and typography within line items
+- DashboardSkeleton updates for the collapsible sections area
+- How to derive and memoize per-group data from budget items

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| UI-DASH-01 | Redesign dashboard with hybrid layout — summary cards, charts, and collapsible category sections (income, bills, expenses, debt, savings) with budget/actual columns | Collapsible sections inserted between chart grid and QuickAdd in DashboardContent; all grouping/totals derived from existing `items` array via useMemo |
+| UI-COLLAPSE-01 | Add collapsible inline sections on dashboard for each category group showing individual line items | Radix Collapsible v1.1.12 already installed and wrapped in collapsible.tsx; exposes `--radix-collapsible-content-height` CSS variable for height animation |
+</phase_requirements>
+
+---
+
+## Summary
+
+Phase 3 adds collapsible per-category sections to the dashboard between the chart grid and the QuickAdd button. The codebase is well-prepared: `collapsible.tsx` wraps Radix Collapsible v1.1.12, the `Badge`, `Table`, and `StatCard` primitives are ready, `categoryColors`/`categoryLabels` from `palette.ts` map cleanly to section styling, and `CATEGORY_TYPES` + `EXPENSE_TYPES` constants already define the display order. `BudgetDetailPage.tsx` already implements identical grouping logic (group items by `category.type`, derive per-group totals, render a `Table` with a `TableFooter` row) — the dashboard sections are a read-only, collapsible variant of that pattern.
+
+The primary technical considerations are: (1) animating the Radix `CollapsibleContent` height smoothly using the `--radix-collapsible-content-height` CSS variable it exposes, (2) preventing `ResizeObserver loop` errors that Recharts can trigger when layout shifts affect chart container dimensions, and (3) threading `budget.carryover_amount` through `SummaryStrip` → `StatCard` to display the carryover subtitle on the balance card.
+
+**Primary recommendation:** Build a `CategorySection` component that wraps `Collapsible`/`CollapsibleTrigger`/`CollapsibleContent` with inline `border-l-4` styling, derive all section data in a single `useMemo` in `DashboardContent`, and isolate Recharts charts in a stable wrapper div to prevent ResizeObserver jank.

+## Standard Stack
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| `@radix-ui/react-collapsible` (via `radix-ui`) | 1.1.12 | Accessible expand/collapse primitive | Already installed; exposes `data-state`, `aria-expanded`, `--radix-collapsible-content-height` |
+| `tailwindcss` | 4.2.x | Utility classes for animation, border accent, spacing | Already in use; v4 `@theme inline` CSS variable pattern used throughout |
+| `lucide-react` | 0.577.x | ChevronRight / ChevronDown icons | Already in use |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| `Badge` (ui/badge.tsx) | — | Budget/Actual chip badges in section header | Used for the two right-aligned total chips |
+| `Table` / `TableBody` / `TableCell` / `TableFooter` (ui/table.tsx) | — | Line-item rows and group total footer | Used for the expanded content table |
+| `StatCard` (dashboard/StatCard.tsx) | — | Balance card needing carryover subtitle | Needs a new optional `subtitle` prop |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| Radix Collapsible | HTML `<details>`/`<summary>` | No animation support; no `data-state` for CSS targeting; not Radix-integrated |
+| CSS height animation via `--radix-collapsible-content-height` | framer-motion `AnimatePresence` | framer-motion not in the stack; adding it would violate the "no new major dependencies" constraint |
+
+**Installation:** No new packages needed. All primitives are already installed.

+
+## Architecture Patterns
+
+### Recommended Project Structure
+
+New files for this phase:
+
+```
+src/components/dashboard/
+├── CategorySection.tsx       # Collapsible section: header + table
+├── CollapsibleSections.tsx   # Renders ordered list of CategorySection
+```
+
+Modified files:
+```
+src/components/dashboard/StatCard.tsx        # Add optional subtitle prop
+src/components/dashboard/SummaryStrip.tsx    # Thread carryover subtitle to balance StatCard
+src/pages/DashboardPage.tsx                  # DashboardContent: add grouped sections data, pass carryover to SummaryStrip
+src/components/dashboard/DashboardSkeleton.tsx  # Add skeleton rows for sections area
+src/i18n/en.json                             # New keys: dashboard.sections.*, dashboard.carryoverIncludes
+src/i18n/de.json                             # German equivalents
+```
+
+### Pattern 1: Radix Collapsible with CSS Height Animation
+
+**What:** `CollapsibleContent` exposes `--radix-collapsible-content-height` as an inline CSS variable on the content div. A Tailwind keyframe animation reads this variable to animate `max-height` from `0` to the measured natural height.
+
+**When to use:** Any time the Radix Collapsible content needs a smooth open/close height transition without a JS animation library.
+
+**How Radix sets the variable (from source):**
+
+```typescript
+// @radix-ui/react-collapsible source (CollapsibleContentImpl)
+style: {
+  [`--radix-collapsible-content-height`]: height ? `${height}px` : undefined,
+  [`--radix-collapsible-content-width`]: width ? `${width}px` : undefined,
+  ...props.style
+}
+```
+
+The `height` value is measured from `getBoundingClientRect()` in a `useLayoutEffect` — it is the element's natural height when fully open. The variable is set on the content div itself.
+
+**Tailwind v4 animation pattern (index.css addition):**
+
+```css
+@theme inline {
+  /* ... existing tokens ... */
+  --animate-collapsible-open: collapsible-open 200ms ease-out;
+  --animate-collapsible-close: collapsible-close 200ms ease-out;
+}
+
+@keyframes collapsible-open {
+  from { height: 0; overflow: hidden; }
+  to   { height: var(--radix-collapsible-content-height); overflow: hidden; }
+}
+
+@keyframes collapsible-close {
+  from { height: var(--radix-collapsible-content-height); overflow: hidden; }
+  to   { height: 0; overflow: hidden; }
+}
+```
+
+**CollapsibleContent usage:**
+
+```tsx
+// Source: Radix Collapsible docs pattern + project CSS variable system
+<CollapsibleContent
+  className="data-[state=open]:animate-collapsible-open data-[state=closed]:animate-collapsible-close overflow-hidden"
+>
+  {/* table content */}
+</CollapsibleContent>
+```
+
+**Key detail:** `data-[state=open]` and `data-[state=closed]` are set by Radix on the `CollapsibleContent` div (from `getState(context.open)` — returns `"open"` or `"closed"`). Tailwind v4's arbitrary variant syntax `data-[state=open]:` works directly against these attributes.
+
+### Pattern 2: Controlled Collapsible with Smart Defaults
+
+**What:** Drive open/close state with local `useState` in `DashboardContent` (not inside `CategorySection`). Compute initial state from budget data, reset when `budgetId` changes (i.e., on month navigation).
+
+**When to use:** When expand state needs to be computed from data (smart defaults) and reset on navigation.
+
+**Example:**
+
+```typescript
+// In DashboardContent — after all item-derived useMemos
+const CATEGORY_TYPES_ALL: CategoryType[] = [
+  "income", "bill", "variable_expense", "debt", "saving", "investment"
+]
+
+const groupedSections = useMemo(() =>
+  CATEGORY_TYPES_ALL
+    .map((type) => {
+      const groupItems = items.filter((i) => i.category?.type === type)
+      if (groupItems.length === 0) return null
+      const budgeted = groupItems.reduce((s, i) => s + i.budgeted_amount, 0)
+      const actual = groupItems.reduce((s, i) => s + i.actual_amount, 0)
+      // Direction-aware over-budget check
+      const isOverBudget =
+        type === "income" || type === "saving" || type === "investment"
+          ? actual < budgeted   // under-earned / under-saved
+          : actual > budgeted   // overspent
+      return { type, items: groupItems, budgeted, actual, isOverBudget }
+    })
+    .filter(Boolean),
+  [items]
+)
+
+// Initial expand state: over-budget sections open, others closed
+// Key on budgetId so state resets when month changes
+const [openSections, setOpenSections] = useState<Record<string, boolean>>(() =>
+  Object.fromEntries(
+    (groupedSections ?? []).map((g) => [g!.type, g!.isOverBudget])
+  )
+)
+
+// Reset when budgetId (month) changes
+useEffect(() => {
+  setOpenSections(
+    Object.fromEntries(
+      (groupedSections ?? []).map((g) => [g!.type, g!.isOverBudget])
+    )
+  )
+}, [budgetId]) // budgetId is the stable dependency; groupedSections flows from it
+```
+
+**Note on Rules of Hooks:** `useState` initializer runs once. The `useEffect` driven by `budgetId` handles the reset-on-navigation requirement without violating hooks rules. All `useMemo` hooks for `groupedSections` must be declared before any early returns (established pattern from Phase 2).
+
+### Pattern 3: CategorySection Component
+
+**What:** A pure presentational component — accepts pre-computed group data and delegates all state management to the parent via `open` / `onOpenChange` props (controlled pattern).
+
+**Example:**
+
+```tsx
+// Source: project conventions + Radix Collapsible controlled pattern
+interface CategorySectionProps {
+  type: CategoryType
+  label: string
+  items: BudgetItem[]
+  budgeted: number
+  actual: number
+  currency: string
+  open: boolean
+  onOpenChange: (open: boolean) => void
+  t: (key: string, opts?: Record<string, unknown>) => string
+}
+
+export function CategorySection({
+  type, label, items, budgeted, actual, currency, open, onOpenChange, t
+}: CategorySectionProps) {
+  const diff = /* direction-aware difference */
+  const isOver = /* direction-aware over-budget flag */
+  const accentColor = categoryColors[type]   // "var(--color-income)" etc.
+
+  return (
+    <Collapsible open={open} onOpenChange={onOpenChange}>
+      <CollapsibleTrigger asChild>
+        <button
+          className="flex w-full items-center gap-3 rounded-md border-l-4 bg-card px-4 py-3 hover:bg-muted/40"
+          style={{ borderLeftColor: accentColor }}
+        >
+          <ChevronRight
+            className="size-4 shrink-0 transition-transform duration-200 [[data-state=open]_&]:rotate-90"
+            aria-hidden
+          />
+          <span className="font-medium">{label}</span>
+          <div className="ml-auto flex items-center gap-2">
+            <Badge variant="outline" className="tabular-nums">
+              {t("budgets.budgeted")} {formatCurrency(budgeted, currency)}
+            </Badge>
+            <Badge variant="secondary" className="tabular-nums">
+              {t("budgets.actual")} {formatCurrency(actual, currency)}
+            </Badge>
+            <span
+              className={cn(
+                "text-sm font-medium tabular-nums",
+                isOver ? "text-over-budget" : "text-on-budget"
+              )}
+            >
+              {formatCurrency(Math.abs(diff), currency)}
+            </span>
+          </div>
+        </button>
+      </CollapsibleTrigger>
+      <CollapsibleContent className="data-[state=open]:animate-collapsible-open data-[state=closed]:animate-collapsible-close overflow-hidden">
+        {/* Table with items + footer */}
+      </CollapsibleContent>
+    </Collapsible>
+  )
+}
+```
+
+**Chevron rotation note:** The `[[data-state=open]_&]:rotate-90` class uses Tailwind v4 ancestor-state targeting. An ancestor element with `data-state="open"` (the `CollapsibleTrigger` button itself has `data-state` set by Radix) rotates the icon. Alternative: target the trigger's own `data-state` with `group-data-[state=open]:rotate-90` if a `group` class is applied to the trigger.
+
+### Pattern 4: StatCard Carryover Subtitle
+
+**What:** Add an optional `subtitle` string prop to `StatCard`. When provided, renders below the value with small muted text. The balance card passes "Includes $X carryover" when `budget.carryover_amount !== 0`.
+
+**Modified StatCard interface:**
+
+```typescript
+interface StatCardProps {
+  title: string
+  value: string
+  valueClassName?: string
+  subtitle?: string          // NEW — optional small text below value
+  subtitleClassName?: string // NEW — optional class override (for negative carryover red)
+  variance?: { ... }
+}
+```
+
+**SummaryStrip carryover prop threading:**
+
+```typescript
+interface SummaryStripProps {
+  income: { value: string; budgeted: string }
+  expenses: { value: string; budgeted: string }
+  balance: { value: string; isPositive: boolean; carryoverSubtitle?: string; carryoverIsNegative?: boolean }
+  t: (key: string) => string
+}
+```
+
+### Anti-Patterns to Avoid
+
+- **Storing expand state inside `CategorySection`:** Breaks the reset-on-navigation requirement. All expand state must live in `DashboardContent` keyed to `budgetId`.
+- **Computing grouped data inside `CategorySection`:** Items should be pre-grouped in `DashboardContent` via `useMemo`. `CategorySection` is purely presentational.
+- **Using `overflow: hidden` on the outer `Collapsible` root:** Only apply `overflow: hidden` to `CollapsibleContent` (animated element), not the outer root, to avoid clipping box-shadows on the header.
+- **Declaring `useState`/`useMemo` after early returns:** Violates React hooks rules. All hooks must be declared before `if (loading) return <DashboardSkeleton />`.
+- **Animating with `max-height: 9999px`:** Produces visible animation lag. Use `--radix-collapsible-content-height` (exact measured height) with `height` animation instead.
+
+---
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Accessible expand/collapse | Custom `aria-expanded` + DOM toggle | `Collapsible` / `CollapsibleTrigger` / `CollapsibleContent` from `ui/collapsible.tsx` | Radix handles `aria-expanded`, `aria-controls`, `id` linkage, keyboard (Enter/Space), and disabled state |
+| Height measurement for animation | `ResizeObserver` + state | `--radix-collapsible-content-height` CSS variable from Radix | Radix measures height in `useLayoutEffect` and sets the variable; no custom measurement needed |
+| Category color accent border | Tailwind color class | Inline `style={{ borderLeftColor: categoryColors[type] }}` | `categoryColors` maps to CSS custom property strings (`"var(--color-income)"`); Tailwind can't generate arbitrary CSS variable values without JIT config |
+
+**Key insight:** The Radix `CollapsibleContent` implementation already handles the tricky edge cases: mount-animation prevention on initial render (the `isMountAnimationPreventedRef.current` flag), measurement timing (uses `useLayoutEffect` to measure before paint), and `hidden` attribute management (element is `hidden` when closed, preventing tab focus and screen reader access to invisible content).
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: ResizeObserver Loop Errors from Recharts
+**What goes wrong:** When collapsible sections open/close, the document layout shifts. Recharts' `ResponsiveContainer` uses a `ResizeObserver` internally. If the observer callback fires mid-layout and triggers a chart re-render that itself changes layout, the browser fires `ResizeObserver loop limit exceeded` console errors.
+
+**Why it happens:** Recharts charts are already rendered above the sections. The layout shift from section expand/collapse propagates upward through the document flow if the chart grid is not height-stable.
+
+**How to avoid:**
+1. Give the chart grid a stable height by ensuring the three chart cards have `min-h-[xxx]` or fixed `h-[xxx]` Tailwind classes. The existing card + `ChartContainer` with `min-h-[250px]` (from Phase 2) already creates a floor.
+2. Wrap the chart grid in a div with `overflow: hidden` or `contain: layout` to prevent section expand/collapse from reflowing chart dimensions.
+3. Use CSS `contain: layout style` on the chart grid container:
+
+```tsx
+{/* 3-column chart grid — isolated from section-toggle reflow */}
+<div className="grid gap-6 md:grid-cols-2 lg:grid-cols-3 [contain:layout_style]">
+  ...charts...
+</div>
+```
+
+**Warning signs:** `ResizeObserver loop limit exceeded` or `ResizeObserver loop completed with undelivered notifications` in the browser console after toggling sections.
+
+**Confidence:** MEDIUM — the `min-h-[250px]` on ChartContainer from Phase 2 may already be sufficient. Add `contain` only if errors appear in testing.
+
+### Pitfall 2: Mount-Time Animation Flicker
+**What goes wrong:** Sections that start expanded (over-budget auto-expand) animate open on first render even though they should appear pre-opened.
+
+**Why it happens:** The Radix `CollapsibleContent` animation keyframe fires on mount if `defaultOpen={true}`.
+
+**How to avoid:** Radix handles this internally: `isMountAnimationPreventedRef.current` is initialized to `isOpen` (true if open on mount), and the `animationName` is set to `"none"` during the initial layout effect, then restored after a `requestAnimationFrame`. This means the animation is suppressed on mount automatically. No additional handling needed.
+
+### Pitfall 3: Chevron Rotation Targeting
+**What goes wrong:** The chevron icon doesn't rotate because the Tailwind ancestor-state class references the wrong ancestor's `data-state`.
+
+**Why it happens:** In Radix Collapsible, the `data-state` attribute is set on both the `CollapsibleTrigger` button element AND the root `Collapsible` div. The icon is a child of the trigger button.
+
+**How to avoid:** Use the trigger's own `data-state` as the ancestor for rotation. The simplest approach — add `group` class to the `CollapsibleTrigger` (or its `asChild` element) and use `group-data-[state=open]:rotate-90` on the icon:
+
+```tsx
+<CollapsibleTrigger asChild>
+  <button className="group flex w-full items-center ...">
+    <ChevronRight className="size-4 transition-transform duration-200 group-data-[state=open]:rotate-90" />
+    ...
+  </button>
+</CollapsibleTrigger>
+```
+
+### Pitfall 4: `useEffect` Reset Dependency Array
+**What goes wrong:** Expand state doesn't reset on month navigation, or resets on every render.
+
+**Why it happens:** Wrong dependency in the `useEffect` that resets `openSections`.
+
+**How to avoid:** Depend on `budgetId` (the string prop from `DashboardContent`), not on `groupedSections` (which changes reference on every render due to `useMemo`). `budgetId` changes exactly when the user navigates months.
+
+### Pitfall 5: i18n Key Interpolation for Carryover Subtitle
+**What goes wrong:** Carryover subtitle shows `"Includes {{amount}} carryover"` as literal text.
+
+**Why it happens:** i18next interpolation requires `t("key", { amount: "..." })` and the JSON to use `{{amount}}` syntax.
+
+**How to avoid:**
+```json
+// en.json
+"dashboard": {
+  "carryoverIncludes": "Includes {{amount}} carryover"
+}
+```
+```typescript
+t("dashboard.carryoverIncludes", { amount: formatCurrency(carryover, currency) })
+```
+
+---
+
+## Code Examples
+
+Verified patterns from source inspection and project conventions:
+
+### Collapsible Controlled Pattern
+```tsx
+// Source: @radix-ui/react-collapsible v1.1.12 type definitions + project conventions
+import { Collapsible, CollapsibleTrigger, CollapsibleContent } from "@/components/ui/collapsible"
+
+<Collapsible open={open} onOpenChange={onOpenChange}>
+  <CollapsibleTrigger asChild>
+    <button className="group flex w-full items-center gap-3 rounded-md border-l-4 px-4 py-3"
+            style={{ borderLeftColor: "var(--color-income)" }}>
+      <ChevronRight className="size-4 shrink-0 transition-transform duration-200 group-data-[state=open]:rotate-90" />
+      <span className="font-medium">Income</span>
+      {/* badges and diff */}
+    </button>
+  </CollapsibleTrigger>
+  <CollapsibleContent className="overflow-hidden data-[state=open]:animate-collapsible-open data-[state=closed]:animate-collapsible-close">
+    {/* table */}
+  </CollapsibleContent>
+</Collapsible>
+```
+
+### CSS Keyframe Animation (index.css addition)
+```css
+/* Source: Radix docs pattern + project @theme inline convention */
+@theme inline {
+  --animate-collapsible-open:  collapsible-open  200ms ease-out;
+  --animate-collapsible-close: collapsible-close 200ms ease-out;
+}
+
+@keyframes collapsible-open {
+  from { height: 0; overflow: hidden; }
+  to   { height: var(--radix-collapsible-content-height); overflow: hidden; }
+}
+
+@keyframes collapsible-close {
+  from { height: var(--radix-collapsible-content-height); overflow: hidden; }
+  to   { height: 0; overflow: hidden; }
+}
+```
+
+### Direction-Aware Over-Budget Logic
+```typescript
+// Source: CONTEXT.md locked decisions
+function isOverBudget(type: CategoryType, budgeted: number, actual: number): boolean {
+  if (type === "income" || type === "saving" || type === "investment") {
+    return actual < budgeted  // under-earned / under-saved = problem
+  }
+  return actual > budgeted    // overspent = problem
+}
+```
+
+### Carryover Subtitle in StatCard
+```typescript
+// Modified StatCard — add optional subtitle prop
+interface StatCardProps {
+  title: string
+  value: string
+  valueClassName?: string
+  subtitle?: string           // e.g. "Includes €150.00 carryover"
+  subtitleClassName?: string  // e.g. "text-over-budget" for negative carryover
+  variance?: { amount: string; direction: "up" | "down" | "neutral"; label: string }
+}

+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| `max-height: 9999px` CSS hack | `height` animation with `--radix-collapsible-content-height` | Radix ~v1.0 | Smooth animation with no lag |
+| Custom `aria-expanded` management | Radix `CollapsibleTrigger` manages `aria-expanded` automatically | Radix v1.x | Correct accessibility with zero effort |
+| Separate `@radix-ui/react-collapsible` install | Included in `radix-ui` v1.4.3 umbrella package | radix-ui monorepo consolidation | Already present in project — no install needed |
+
+**Deprecated/outdated:**
+- `defaultOpen` on `Collapsible` root: Still valid, but we use controlled `open` + `onOpenChange` for the reset-on-navigation requirement
+- `hidden` prop removed from `CollapsibleContent` in newer Radix: Radix manages `hidden` attribute internally; never pass it manually
+
+---
+
+## Open Questions
+
+1. **CSS `contain` on chart grid to prevent ResizeObserver errors**
+   - What we know: Recharts uses ResizeObserver; layout shifts from sections opening can trigger loop errors
+   - What's unclear: Whether Phase 2's `min-h-[250px]` on charts is already sufficient to prevent jank
+   - Recommendation: Implement without `contain` first; add `[contain:layout_style]` to chart grid div only if ResizeObserver errors appear in manual testing
+
+2. **Tailwind v4 `data-[]` variant syntax for `group-data-[state=open]`**
+   - What we know: Tailwind v4 supports arbitrary group variants; the project uses `group` pattern already (sidebar.tsx)
+   - What's unclear: Whether Tailwind v4's JIT generates `group-data-[state=open]:` without explicit config
+   - Recommendation: Use it — Tailwind v4 generates arbitrary variants JIT; if it doesn't compile, fall back to the `[[data-state=open]_&]:rotate-90` CSS selector approach

+
+## Validation Architecture
+
+### Test Framework
+| Property | Value |
+|----------|-------|
+| Framework | None installed — no test infrastructure in project |
+| Config file | None — Wave 0 would need `vitest.config.ts` |
+| Quick run command | N/A |
+| Full suite command | `bun run lint` (only automated check available) |
+
+### Phase Requirements → Test Map
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| UI-DASH-01 | Collapsible sections render between charts and QuickAdd | manual-only | — | N/A |
+| UI-DASH-01 | Over-budget sections auto-expand on load | manual-only | — | N/A |
+| UI-DASH-01 | Carryover subtitle appears on balance card when non-zero | manual-only | — | N/A |
+| UI-COLLAPSE-01 | Section expands/collapses with smooth animation | manual-only | — | N/A |
+| UI-COLLAPSE-01 | No ResizeObserver loop errors on rapid toggle | manual-only | browser console check | N/A |
+| UI-COLLAPSE-01 | Empty category groups are hidden | manual-only | — | N/A |
+| UI-COLLAPSE-01 | State resets on month navigation | manual-only | — | N/A |
+
+**Justification for manual-only:** No test framework is installed. The project has no `vitest`, `jest`, `@testing-library/react`, or similar. Installing a test framework is out of scope for Phase 3 (the project's TESTING.md notes this explicitly). All validation will be manual browser testing.
+
+The primary automated check available is `bun run lint` (ESLint), which catches hooks rules violations, unused variables, and TypeScript errors.
+
+### Sampling Rate
+- **Per task commit:** `bun run lint` (catches TypeScript errors and hooks violations)
+- **Per wave merge:** `bun run build` (full TypeScript compile + Vite bundle)
+- **Phase gate:** Manual browser testing of all 7 behaviors above before `/gsd:verify-work`
+
+### Wave 0 Gaps
+None — no test infrastructure to create. Lint and build are the only automated gates.
+
+---
+
+## Sources
+
+### Primary (HIGH confidence)
+- `node_modules/@radix-ui/react-collapsible/dist/index.mjs` — Full source inspection of `CollapsibleContentImpl`; confirmed `--radix-collapsible-content-height` CSS variable, `data-state` values `"open"`/`"closed"`, `hidden` attribute management, mount-animation prevention via `isMountAnimationPreventedRef`
+- `node_modules/@radix-ui/react-collapsible/dist/index.d.ts` — Confirmed type signatures: `CollapsibleProps.open`, `CollapsibleProps.onOpenChange`, `CollapsibleProps.defaultOpen`
+- `src/components/ui/collapsible.tsx` — Confirmed wrapper already in project, exports `Collapsible`, `CollapsibleTrigger`, `CollapsibleContent`
+- `src/pages/DashboardPage.tsx` — Confirmed existing `DashboardContent` structure, `useMemo` placement before early returns, `budget.carryover_amount` already in scope
+- `src/pages/BudgetDetailPage.tsx` — Confirmed grouping pattern (`CATEGORY_TYPES.map`, `items.filter`, per-group totals), `Table`/`TableFooter` pattern, `DifferenceCell` logic
+- `src/lib/palette.ts` — Confirmed `categoryColors` returns `"var(--color-income)"` etc.; `categoryLabels` for EN/DE display strings
+- `src/lib/types.ts` — Confirmed `Budget.carryover_amount: number`, `BudgetItem.category?.type`
+- `src/index.css` — Confirmed `--color-over-budget`, `--color-on-budget` semantic tokens; `@theme inline` pattern for CSS custom properties
+- `src/i18n/en.json` + `de.json` — Confirmed existing keys; identified gaps for new keys
+- `src/components/dashboard/StatCard.tsx` — Confirmed current interface (no subtitle prop); variance prop pattern
+
+### Secondary (MEDIUM confidence)
+- `.planning/codebase/CONVENTIONS.md` — Component structure, hooks-before-returns rule, import ordering, TypeScript strict mode
+- `.planning/codebase/TESTING.md` — Confirmed no test framework installed; lint/build are only automated checks
+- `.planning/STATE.md` — Confirmed pre-existing lint errors in unrelated files; Phase 2 patterns (useMemo before early returns, QuickAdd position)
+
+### Tertiary (LOW confidence)
+- None — all findings verified against installed source code
+
+---
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH — all libraries inspected from installed node_modules source
+- Architecture: HIGH — patterns derived directly from existing codebase files
+- Pitfalls: MEDIUM — ResizeObserver issue is known Recharts behavior; specific CSS `contain` fix is speculative pending testing
+- Animation pattern: HIGH — `--radix-collapsible-content-height` confirmed from source, Tailwind v4 `data-[]` variants confirmed from existing sidebar.tsx usage
+
+**Research date:** 2026-03-17
+**Valid until:** 2026-04-17 (stable libraries; CSS variables are fixed in installed source)

+## Goal Achievement
+
+### Observable Truths — Plan 01
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Balance card shows 'Includes $X carryover' subtitle when carryover is non-zero | VERIFIED | `StatCard` renders `{subtitle && <p>}` (line 49). `SummaryStrip` passes `balance.carryoverSubtitle` to StatCard subtitle prop (line 47). `DashboardPage` computes `carryoverSubtitle` from `budget.carryover_amount !== 0` (lines 179-182). |
+| 2 | Balance card has no subtitle when carryover is zero | VERIFIED | `carryoverSubtitle` is set to `undefined` when `carryover === 0` (line 182). StatCard only renders the subtitle element when truthy (line 49). |
+| 3 | Negative carryover displays with red styling | VERIFIED | `carryoverIsNegative = carryover < 0` (line 183). `SummaryStrip` passes `subtitleClassName={balance.carryoverIsNegative ? "text-over-budget" : undefined}` to StatCard (line 48). |
+| 4 | CategorySection renders with left border accent, chevron, label, badges, and difference | VERIFIED | `CategorySection.tsx` lines 73-97: `border-l-4` with `borderLeftColor: categoryColors[type]`, `ChevronRight` with `group-data-[state=open]:rotate-90`, label span, two `Badge` components, and color-coded difference span. |
+| 5 | CollapsibleSections renders an ordered list of CategorySection components | VERIFIED | `CollapsibleSections.tsx` maps `groups` array to `<CategorySection key={group.type} .../>` (lines 29-42). |
+| 6 | Collapsible animation tokens are defined in CSS | VERIFIED | `index.css` lines 75-76: `--animate-collapsible-open` and `--animate-collapsible-close`. Keyframes at lines 81-89. `CategorySection` uses `data-[state=open]:animate-collapsible-open data-[state=closed]:animate-collapsible-close` (line 99). |
+
+### Observable Truths — Plan 02
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 7 | Each non-empty category group renders as a collapsible section between charts and QuickAdd | VERIFIED | `DashboardPage.tsx` lines 249-258: `CollapsibleSections` inserted after chart grid and before QuickAdd. `groupedSections` filters null (empty) groups. |
+| 8 | Over-budget sections auto-expand on load (direction-aware) | VERIFIED | `isOverBudget` helper (lines 44-49) distinguishes spending vs income/saving/investment. `openSections` lazy initializer maps each group to `isOverBudget(g.type, g.budgeted, g.actual)` (lines 157-161). |
+| 9 | On/under-budget sections start collapsed | VERIFIED | Same lazy initializer: `isOverBudget` returns false for on-budget groups, so their initial open state is `false`. |
+| 10 | Empty category groups are hidden entirely | VERIFIED | `groupedSections` useMemo returns null for any type with `groupItems.length === 0` and filters nulls out (lines 142, 153). Render gate: `groupedSections.length > 0 &&` (line 250). |
+| 11 | Expand/collapse state resets when navigating months | VERIFIED | `DashboardContent` is keyed by `key={currentBudget.id}` (line 330). Month navigation changes `currentBudget.id`, causing full remount and re-initialization of `openSections` from the lazy initializer. |
+| 12 | Toggling sections does not produce ResizeObserver loop errors or chart resize jank | NEEDS HUMAN | Runtime browser behavior — not statically verifiable. |
+| 13 | Collapsible sections animate open/close smoothly with no flicker on mount | NEEDS HUMAN | Visual quality requires browser rendering. |
+| 14 | DashboardSkeleton mirrors the sections area layout | VERIFIED | `DashboardSkeleton.tsx` lines 56-69: 3 skeleton rows each matching the real CategorySection header structure (chevron, label, two badges, difference span). |
+
+**Score:** 13/14 truths verified — 1 needs human verification (split across 2 items: ResizeObserver and animation quality)

+## Requirements Coverage
+
+| Requirement | Source Plans | Description | Status | Evidence |
+|-------------|-------------|-------------|--------|----------|
+| UI-DASH-01 | 03-01-PLAN, 03-02-PLAN | Redesign dashboard with hybrid layout — summary cards, charts, and collapsible category sections with budget/actual columns | SATISFIED | Phase 3 completes the collapsible sections layer. `DashboardContent` now renders: SummaryStrip → 3-column charts → CollapsibleSections → QuickAdd. Budget/actual columns present in 4-column line-item tables. |
+| UI-COLLAPSE-01 | 03-01-PLAN, 03-02-PLAN | Add collapsible inline sections on dashboard for each category group showing individual line items | SATISFIED | `CategorySection` renders collapsible sections per category group. Expand reveals 4-column table with individual `BudgetItem` rows. `CollapsibleSections` wired into `DashboardContent`. |
+
+No orphaned requirements: ROADMAP.md maps exactly UI-DASH-01 and UI-COLLAPSE-01 to Phase 3, both claimed in both plans, both satisfied.
+
+---
+
+## Anti-Patterns Found
+
+Scanned: `CategorySection.tsx`, `CollapsibleSections.tsx`, `DashboardPage.tsx`, `DashboardSkeleton.tsx`, `StatCard.tsx`, `SummaryStrip.tsx`
+
+| File | Pattern | Severity | Impact |
+|------|---------|----------|--------|
+| — | No TODO/FIXME/placeholder/empty returns found in phase 3 files | — | None |
+
+Pre-existing lint errors (6 errors in `MonthNavigator.tsx`, `badge.tsx`, `button.tsx`, `sidebar.tsx`, `useBudgets.ts`) are unchanged from before Phase 3 and documented in STATE.md. None are in files modified by this phase.
+
+Build result: `bun run build` passes cleanly in 457ms with 2583 modules transformed.
+
+---
+
+## Key Deviation: Plan 02 State Reset Implementation
+
+Plan 02 specified `useEffect(() => setOpenSections(...), [budgetId])` for month navigation reset.
+
+Actual implementation uses `key={currentBudget.id}` on `<DashboardContent>` (DashboardPage.tsx line 330). This causes React to fully remount `DashboardContent` on month change, cleanly resetting `openSections` via the lazy `useState` initializer without violating the project's strict `react-hooks/set-state-in-effect` and `react-hooks/refs` lint rules.
+
+Functional outcome is identical to the plan intent. This is an improvement, not a gap.
+
+---
+
+## Human Verification Required
+
+### 1. ResizeObserver Loop Check
+
+**Test:** Open the dashboard on a month with budget items. Open the browser DevTools console (F12). Rapidly toggle collapsible sections open and closed 10+ times in quick succession.
+**Expected:** No "ResizeObserver loop limit exceeded" or "ResizeObserver loop completed with undelivered notifications" messages appear in the console. Charts above the sections do not resize or jitter.
+**Why human:** ResizeObserver loop errors are a runtime browser behavior caused by Recharts' resize handling interacting with DOM mutations. They are not detectable by static analysis, TypeScript compilation, or lint. The structural isolation (sections rendered below the chart grid, `CollapsibleContent` animating only the section's own height via `--radix-collapsible-content-height`) is correct, but only browser rendering can confirm the absence of the error.
+
+### 2. Animation Smoothness and Mount Flicker
+
+**Test:** Navigate to a month with budget items. Observe the initial page render. Then expand and collapse 2-3 sections.
+**Expected:** On initial load, sections that start collapsed show no animation flash. The 200ms expand/collapse animation (`collapsible-open`/`collapsible-close` keyframes) plays smoothly without layout flicker or jump.
+**Why human:** CSS animation visual quality — smoothness, absence of flicker, height interpolation behavior — requires browser rendering. The keyframes and `data-[state]` variants are correctly defined in code, but only a browser can render and confirm the visual result.
+
+---
+
+## Gaps Summary
+
+No automated gaps. All 14 must-have truths are either VERIFIED (13) or flagged for human verification (1, split into 2 human tests). All artifacts exist, are substantive, and are correctly wired. Both requirement IDs (UI-DASH-01, UI-COLLAPSE-01) are satisfied with clear implementation evidence. Build passes cleanly.
+
+The phase is structurally complete. Human verification of runtime browser behavior is the only remaining check before marking Phase 3 done in ROADMAP.md.

+<objective>
+Redesign the Login and Register pages with brand presence and visual polish matching the established design system.
+
+Purpose: Auth pages are the first impression of the app. Currently they use a plain `bg-background` with a bare card. This plan upgrades them to use a muted background, app logo, card accent styling, and provider SVG icons on OAuth buttons -- establishing visual consistency from the very first screen.
+
+Output: Redesigned LoginPage.tsx, RegisterPage.tsx, and new i18n keys for auth subtitles.

+# Phase 4 Plan 01: Auth Page Redesign Summary
+
+**LoginPage and RegisterPage redesigned with muted background, primary-accent card border, favicon logo, subtitle text, and inline SVG OAuth provider icons**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-17T15:08:11Z
+- **Completed:** 2026-03-17T15:10:30Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Both auth pages now use `bg-muted/60` background for visual depth instead of flat `bg-background`
+- Card accent (`border-t-4 border-t-primary shadow-lg`) applied consistently on both pages
+- `favicon.svg` app logo placed above the CardTitle for brand presence on first impression
+- Google and GitHub OAuth buttons on LoginPage now show inline SVG provider icons with `gap-2` spacing
+- `auth.loginSubtitle` and `auth.registerSubtitle` i18n keys added to both `en.json` and `de.json`
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Redesign LoginPage with brand presence and OAuth icons** - `36d068e` (feat)
+2. **Task 2: Redesign RegisterPage to match LoginPage treatment** - `0ff9939` (feat)
+
+**Plan metadata:** (docs commit — see below)
+
+## Files Created/Modified
+- `src/pages/LoginPage.tsx` - Redesigned with muted bg, card accent, logo, subtitle, SVG OAuth icons
+- `src/pages/RegisterPage.tsx` - Redesigned to match LoginPage visual treatment, no OAuth buttons
+- `src/i18n/en.json` - Added auth.loginSubtitle and auth.registerSubtitle keys
+- `src/i18n/de.json` - Added German translations for both new auth subtitle keys
+
+## Decisions Made
+- Inline SVG paths used for Google and GitHub icons — avoids pulling in an external icon library while keeping icons crisp at any scale and fully styled via Tailwind
+- `auth.registerSubtitle` key was added in Task 1 alongside `loginSubtitle` for atomicity, even though it's only consumed by RegisterPage in Task 2 — this matches the plan's instruction to "update both en.json and de.json atomically in this task"
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - all steps completed cleanly, `bun run build` passed after each task.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Auth page visual treatment is complete; 04-02 and 04-03 plans can build on this established design pattern
+- The card accent pattern (border-t-4 border-t-primary) and muted background are now documented for potential reuse in other full-page forms

+<objective>
+Apply PageShell, skeleton loading states, and group header upgrades to the four CRUD/settings pages (Categories, Template, QuickAdd, Settings).
+
+Purpose: These four authenticated pages currently use inline `<h1>` + action div headers, return `null` while loading, and use small-dot group headers. This plan upgrades them to match the dashboard's design language -- consistent headers via PageShell, skeleton loading placeholders, and left-border accent group headers.
+
+Output: Four updated page components with consistent design system application, plus new i18n keys for page descriptions.

+             ))}
+           </div>
+         ))}
+       </div>
+     </PageShell>
+   )
+   ```
+
+4. **Group header upgrade:** Replace the plain dot group header pattern in the `grouped.map` with the left-border accent pattern:
+   ```tsx
+   <div
+     className="mb-2 flex items-center gap-3 rounded-sm border-l-4 bg-muted/30 px-3 py-2"
+     style={{ borderLeftColor: categoryColors[type] }}
+   >
+     <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+   </div>
+   ```
+   Remove the old `<div className="mb-2 flex items-center gap-2">` block with the `size-3 rounded-full` dot and `<h2>`.
+
+**TemplatePage.tsx changes:**
+
+1. **Import PageShell and Skeleton:** Same imports as CategoriesPage.
+
+2. **Replace header:** The TemplatePage header has an inline-editable `TemplateName` component. Wrap with PageShell, putting TemplateName as the title area. Since PageShell accepts a `title` string but TemplateName is a component, use PageShell differently here:
+
+   Instead of wrapping with PageShell using `title` prop, replace the header div with PageShell but pass the template name as a plain string title when NOT editing. Actually, the TemplateName component handles its own editing state inline. The cleanest approach: keep the TemplateName component but wrap the page content differently.
+
+   Replace the entire page structure:
+   ```tsx
+   <div>
+     {/* Header */}
+     <div className="mb-6 flex items-center justify-between gap-4">
+       <TemplateName ... />
+       <Button ...>...</Button>
+     </div>
+     ...
+   </div>
+   ```
+
+   With:
+   ```tsx
+   <PageShell
+     title={template?.name ?? t("template.title")}
+     action={
+       <div className="flex items-center gap-2">
+         <Button onClick={openCreate} size="sm" disabled={isSaving}>
+           <Plus className="mr-1 size-4" />
+           {t("template.addItem")}
+         </Button>
+       </div>
+     }
+   >
+     ...
+   </PageShell>
+   ```
+
+   **Note:** The TemplateName inline-edit functionality is a nice feature that will be lost if we just use a plain title string. To preserve it while using PageShell: remove the `title` prop from PageShell and instead render TemplateName inside the PageShell children, ABOVE the content. Actually, the simplest correct approach is to NOT use PageShell's title prop for TemplatePage -- instead, pass a custom `action` that includes the Add button, and render TemplateName as the first child inside PageShell with the title styling matching PageShell's own h1 style. But this defeats the purpose.
+
+   Best approach: Use PageShell for the layout but pass the TemplateName component as a React node for the title slot. Since PageShell only accepts `title: string`, we need to slightly modify the approach. Just use PageShell's wrapper layout manually:
+
+   Replace the header with:
+   ```tsx
+   <div className="flex flex-col gap-6">
+     <div className="flex items-start justify-between gap-4">
+       <TemplateName
+         name={template?.name ?? t("template.title")}
+         onSave={handleNameSave}
+       />
+       <div className="shrink-0">
+         <Button onClick={openCreate} size="sm" disabled={isSaving}>
+           <Plus className="mr-1 size-4" />
+           {t("template.addItem")}
+         </Button>
+       </div>
+     </div>
+     {/* rest of content */}
+   </div>
+   ```
+
+   This mirrors PageShell's exact DOM structure (flex flex-col gap-6 > flex items-start justify-between gap-4) without importing PageShell, since TemplateName is a custom component that cannot be a plain string. This keeps visual consistency.
+
+   Additionally, update TemplateName's `<h1>` to use `className="text-2xl font-semibold tracking-tight"` (add `tracking-tight` to match PageShell's h1 styling).
+
+3. **Skeleton loading:** Replace `if (loading) return null` with a skeleton that mirrors the template page layout:
+   ```tsx
+   if (loading) return (
+     <div className="flex flex-col gap-6">
+       <div className="flex items-start justify-between gap-4">
+         <Skeleton className="h-8 w-48" />
+         <Skeleton className="h-9 w-24" />
+       </div>
+       <div className="space-y-6">
+         {[1, 2].map((i) => (
+           <div key={i} className="space-y-2">
+             <div className="flex items-center gap-3 rounded-sm border-l-4 border-muted bg-muted/30 px-3 py-2">
+               <Skeleton className="h-4 w-28" />
+             </div>
+             {[1, 2, 3].map((j) => (
+               <div key={j} className="flex items-center gap-4 px-4 py-2.5 border-b border-border">
+                 <Skeleton className="h-4 w-36" />
+                 <Skeleton className="h-5 w-16 rounded-full" />
+                 <Skeleton className="ml-auto h-4 w-20" />
+                 <Skeleton className="h-7 w-7 rounded-md" />
+               </div>
+             ))}
+           </div>
+         ))}
+       </div>
+     </div>
+   )
+   ```
+
+4. **Group header upgrade:** Same left-border accent pattern as CategoriesPage. Replace the dot+h2 pattern in grouped.map with:
+   ```tsx
+   <div
+     className="mb-2 flex items-center gap-3 rounded-sm border-l-4 bg-muted/30 px-3 py-2"
+     style={{ borderLeftColor: categoryColors[type] }}
+   >
+     <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+   </div>
+   ```
+
+**i18n: No new keys needed for this task.** Categories and Template pages already have all required i18n keys. The page descriptions are optional (Claude's discretion) -- skip them for these two pages since the page purpose is self-evident from the content.

+  <files>src/pages/QuickAddPage.tsx, src/pages/SettingsPage.tsx</files>
+  <action>
+**QuickAddPage.tsx changes:**
+
+1. **Import PageShell and Skeleton:** Add `import { PageShell } from "@/components/shared/PageShell"` and `import { Skeleton } from "@/components/ui/skeleton"`.
+
+2. **Replace header:** Remove the `<div className="mb-6 flex items-center justify-between">` header block. Wrap the entire return in:
+   ```tsx
+   <PageShell
+     title={t("quickAdd.title")}
+     action={
+       <Button onClick={openCreate} size="sm">
+         <Plus className="mr-1 size-4" />

+       </Button>
+     }
+   >
+     {/* empty state + table + dialog */}
+   </PageShell>
+   ```
+   Remove the wrapping `<div>` root since PageShell provides the outer container.
+
+3. **Skeleton loading:** Replace `if (loading) return null` with:
+   ```tsx
+   if (loading) return (
+     <PageShell title={t("quickAdd.title")}>
+       <div className="space-y-1">
+         {[1, 2, 3, 4, 5].map((i) => (
+           <div key={i} className="flex items-center gap-4 px-4 py-2.5 border-b border-border">
+             <Skeleton className="h-5 w-10 rounded-full" />
+             <Skeleton className="h-4 w-36" />
+             <Skeleton className="ml-auto h-7 w-7 rounded-md" />
+           </div>
+         ))}
+       </div>
+     </PageShell>
+   )
+   ```
+
+**SettingsPage.tsx changes:**
+
+1. **Import PageShell and Skeleton:** Add `import { PageShell } from "@/components/shared/PageShell"` and `import { Skeleton } from "@/components/ui/skeleton"`.
+
+2. **Remove duplicate heading:** Delete the `<h1 className="mb-6 text-2xl font-semibold">{t("settings.title")}</h1>` on line 67. This creates a double heading since the Card below also has a CardTitle with "Settings".
+
+3. **Wrap with PageShell:** Replace the `<div className="max-w-lg">` root with:
+   ```tsx
+   <PageShell title={t("settings.title")}>
+     <div className="max-w-lg">
+       <Card>
+         {/* Remove CardHeader with CardTitle since PageShell provides the title.
+             Keep CardContent as-is. */}
+         <CardContent className="space-y-4 pt-6">
+           {/* existing form fields unchanged */}
+         </CardContent>
+       </Card>
+     </div>
+   </PageShell>
+   ```
+   Remove the CardHeader and CardTitle entirely -- PageShell provides the page-level title, and the Card should just contain the form. Add `pt-6` to CardContent's className since without CardHeader the content needs top padding.
+
+4. **Skeleton loading:** Replace `if (loading) return null` with:
+   ```tsx
+   if (loading) return (
+     <PageShell title={t("settings.title")}>
+       <div className="max-w-lg">
+         <Card>
+           <CardContent className="space-y-4 pt-6">
+             {[1, 2, 3].map((i) => (
+               <div key={i} className="space-y-2">
+                 <Skeleton className="h-4 w-24" />
+                 <Skeleton className="h-10 w-full" />
+               </div>
+             ))}

+           </CardContent>
+         </Card>
+       </div>
+     </PageShell>
+   )
+   ```
+
+5. **Clean up unused imports:** After removing CardHeader and CardTitle usage, update the import to: `import { Card, CardContent } from "@/components/ui/card"`. Remove `CardHeader` and `CardTitle` from the import.
+
+**No i18n changes needed for this task.** QuickAdd and Settings pages already have all required translation keys.

+# Phase 04 Plan 02: CRUD Pages Design Consistency Summary
+
+**PageShell adoption, skeleton loading states, and left-border accent group headers applied to all four CRUD/settings pages (Categories, Template, QuickAdd, Settings)**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-03-17T15:13:33Z
+- **Completed:** 2026-03-17T15:16:40Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+
+- All four pages now use PageShell-consistent headers (flex-col gap-6, items-start justify-between gap-4) — consistent with dashboard design language
+- All four pages show skeleton loading states instead of blank screens while data loads
+- Categories and Template pages show left-border accent group headers replacing plain dot+h2 pattern
+- Settings page now has exactly one "Settings" heading — removed duplicate h1 and CardHeader/CardTitle
+- TemplateName inline-edit functionality preserved by mirroring PageShell DOM structure manually
+
+## Task Commits
+
+1. **Task 1: Upgrade CategoriesPage and TemplatePage** - `e9497e4` (feat)
+2. **Task 2: Upgrade QuickAddPage and SettingsPage** - `ba19c30` (feat)
+
+**Plan metadata:** (docs commit follows)
+
+## Files Created/Modified
+
+- `src/pages/CategoriesPage.tsx` - PageShell header, skeleton loading, left-border accent group headers
+- `src/pages/TemplatePage.tsx` - PageShell-mirrored layout, skeleton loading, left-border accent group headers, tracking-tight on h1
+- `src/pages/QuickAddPage.tsx` - PageShell header with Add button, skeleton loading (5-row table pattern)
+- `src/pages/SettingsPage.tsx` - PageShell header, removed duplicate h1 and CardHeader/CardTitle, skeleton loading
+
+## Decisions Made
+
+- TemplatePage uses manually-mirrored PageShell layout (flex-col gap-6) instead of importing PageShell directly, because TemplateName is a custom interactive component (inline-edit) that cannot be passed as a plain string `title` prop
+- SettingsPage CardHeader and CardTitle are removed; PageShell handles the page title; Card now only wraps form content with pt-6 on CardContent
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All four authenticated CRUD/settings pages now match the dashboard's design language
+- Phase 04 fully complete — all pages use consistent PageShell headers, skeleton loading states, and (where applicable) left-border accent group headers
+- No blockers

+<objective>
+Upgrade BudgetListPage and BudgetDetailPage with PageShell, semantic color tokens, direction-aware diff logic, locale-aware month formatting, and skeleton loading states.
+
+Purpose: These are the most complex pages in the app. BudgetDetailPage currently uses hardcoded `text-green-600`/`text-red-600` color classes that bypass the design token system, a simplified `isIncome` boolean that mishandles saving/investment types, and a hardcoded `"en"` locale for month formatting. BudgetListPage has a hardcoded English MONTHS array. This plan migrates both to the established design system patterns from Phases 1-3.
+
+Output: Two fully upgraded budget pages with consistent visual language, correct semantic tokens, and locale-aware formatting.

+From src/components/shared/PageShell.tsx:

+interface PageShellProps {
+  title: string
+  description?: string
+  action?: React.ReactNode
+  children: React.ReactNode
+}
+export function PageShell({ title, description, action, children }: PageShellProps)
+```
+
+From src/components/dashboard/CategorySection.tsx (direction-aware diff logic to replicate):
+```tsx
+const SPENDING_TYPES: CategoryType[] = ["bill", "variable_expense", "debt"]
+
+function isSpendingType(type: CategoryType): boolean {
+  return SPENDING_TYPES.includes(type)
+}
+

+  if (isSpendingType(type)) {
+    return { diff: budgeted - actual, isOver: actual > budgeted }
+  }
+  return { diff: actual - budgeted, isOver: actual < budgeted }
+}
+```
+
+Semantic color classes (from index.css Phase 1):
+- `text-over-budget` -- red, for amounts exceeding budget
+- `text-on-budget` -- green, for amounts within budget
+- `text-muted-foreground` -- neutral, for zero difference
+
+Group header pattern (established in Plan 02):
+```tsx
+<div
+  className="mb-2 flex items-center gap-3 rounded-sm border-l-4 bg-muted/30 px-3 py-2"
+  style={{ borderLeftColor: categoryColors[type] }}
+>
+  <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+</div>
+```
+
+Locale-aware month formatting pattern:
+```tsx
+const { i18n } = useTranslation()
+const locale = i18n.language
+// Replace hardcoded MONTHS array:
+const monthItems = useMemo(
+  () => Array.from({ length: 12 }, (_, i) => ({
+    value: i + 1,
+    label: new Intl.DateTimeFormat(locale, { month: "long" }).format(new Date(2000, i, 1)),
+  })),
+  [locale]
+)
+// Replace hardcoded "en" in toLocaleDateString:
+function budgetHeading(startDate: string, locale: string): string {
+  const [year, month] = startDate.split("-").map(Number)

+  <name>Task 1: Upgrade BudgetListPage with PageShell, locale-aware months, skeleton, and i18n labels</name>
+  <files>src/pages/BudgetListPage.tsx, src/i18n/en.json, src/i18n/de.json</files>
+  <action>
+**BudgetListPage.tsx changes:**
+
+1. **Import PageShell, Skeleton, useMemo:** Add:
+   ```tsx
+   import { useState, useMemo } from "react"
+   import { PageShell } from "@/components/shared/PageShell"
+   import { Skeleton } from "@/components/ui/skeleton"
+   ```
+
+2. **Remove hardcoded MONTHS array:** Delete the entire `const MONTHS = [...]` constant (lines 36-49).
+
+3. **Add locale-aware month generation:** Inside the component, after the existing hooks and state, add:
+   ```tsx
+   const { t, i18n } = useTranslation()
+   const locale = i18n.language
+
+   const monthItems = useMemo(
+     () =>
+       Array.from({ length: 12 }, (_, i) => ({
+         value: i + 1,
+         label: new Intl.DateTimeFormat(locale, { month: "long" }).format(
+           new Date(2000, i, 1)
+         ),
+       })),
+     [locale]
+   )
+   ```
+   Update the existing `useTranslation()` call to also destructure `i18n`: change `const { t } = useTranslation()` to `const { t, i18n } = useTranslation()`.
+
+   **Rules of Hooks:** The `useMemo` must be declared BEFORE the `if (loading)` check. Since `useTranslation` is already before it, just place `useMemo` right after the state declarations and before `if (loading)`.
+
+4. **Fix budgetLabel to use locale:** Replace the `budgetLabel` helper function to use locale:
+   ```tsx
+   function budgetLabel(budget: Budget, locale: string): string {
+     const [year, month] = budget.start_date.split("-").map(Number)
+     return new Intl.DateTimeFormat(locale, { month: "long", year: "numeric" }).format(
+       new Date(year ?? 0, (month ?? 1) - 1, 1)
+     )
+   }
+   ```
+   Update all call sites to pass `locale`: `budgetLabel(budget, locale)` and `budgetLabel(result, locale)`.
+
+5. **Replace MONTHS usage in dialog:** In the month Select, replace `MONTHS.map((m) =>` with `monthItems.map((m) =>`. The shape is identical (`{ value, label }`).
+
+6. **Replace hardcoded "Month" and "Year" labels:** Replace the `<Label>Month</Label>` and `<Label>Year</Label>` in the new budget dialog with:
+   ```tsx
+   <Label>{t("budgets.month")}</Label>
+   // and
+   <Label>{t("budgets.year")}</Label>
+   ```
+
+7. **Replace header with PageShell:** Remove the `<div className="mb-6 flex items-center justify-between">` header block. Wrap the return in:
+   ```tsx
+   <PageShell
+     title={t("budgets.title")}
+     action={
+       <Button onClick={openDialog} size="sm">
+         <Plus className="mr-1 size-4" />
+         {t("budgets.newBudget")}
+       </Button>
+     }
+   >
+     {/* empty state + table + dialog */}
+   </PageShell>
+   ```
+
+8. **Skeleton loading:** Replace `if (loading) return null` with:
+   ```tsx
+   if (loading) return (
+     <PageShell title={t("budgets.title")}>
+       <div className="space-y-1">
+         {[1, 2, 3, 4].map((i) => (
+           <div key={i} className="flex items-center gap-4 px-4 py-3 border-b border-border">
+             <Skeleton className="h-4 w-40" />
+             <Skeleton className="h-4 w-12" />
+             <Skeleton className="ml-auto h-4 w-4" />
+           </div>
+         ))}
+       </div>
+     </PageShell>
+   )
+   ```
+
+**i18n additions (en.json):** Add inside the "budgets" object:
+```json
+"month": "Month",
+"year": "Year",
+"total": "{{label}} Total"
+```
+
+**i18n additions (de.json):** Add inside the "budgets" object:
+```json
+"month": "Monat",
+"year": "Jahr",
+"total": "{{label}} Gesamt"
+```
+  </action>
+  <verify>
+    <automated>cd /home/jlmak/Projects/jlmak/SimpleFinanceDash && bun run build</automated>
+  </verify>
+  <done>BudgetListPage uses PageShell, shows locale-aware month names via Intl.DateTimeFormat (no hardcoded English MONTHS array), dialog labels use i18n keys, skeleton replaces null loading state, budgetLabel uses i18n.language locale. Both en.json and de.json have month/year/total keys. Build passes.</done>

+
+<task type="auto">
+  <name>Task 2: Upgrade BudgetDetailPage with semantic tokens, direction-aware diff, PageShell, group headers, and skeleton</name>
+  <files>src/pages/BudgetDetailPage.tsx</files>
+  <action>
+**BudgetDetailPage.tsx changes:**
+
+1. **Import additions:** Add:
+   ```tsx
+   import { cn } from "@/lib/utils"
+   import { PageShell } from "@/components/shared/PageShell"
+   import { Skeleton } from "@/components/ui/skeleton"
+   ```
+
+2. **Add direction-aware diff logic:** At module level (above the component), add the same SPENDING_TYPES pattern from CategorySection:
+   ```tsx
+   const SPENDING_TYPES: CategoryType[] = ["bill", "variable_expense", "debt"]
+
+   function isSpendingType(type: CategoryType): boolean {
+     return SPENDING_TYPES.includes(type)
+   }
+   ```
+
+3. **Rewrite DifferenceCell:** Replace the entire DifferenceCell component. Change its props: remove `isIncome`, add `type: CategoryType`:
+   ```tsx
+   function DifferenceCell({
+     budgeted,
+     actual,
+     currency,
+     type,
+   }: {
+     budgeted: number
+     actual: number
+     currency: string
+     type: CategoryType
+   }) {
+     const isOver = isSpendingType(type)
+       ? actual > budgeted
+       : actual < budgeted
+     const diff = isSpendingType(type)
+       ? budgeted - actual
+       : actual - budgeted
+
+     return (
+       <TableCell
+         className={cn(
+           "text-right tabular-nums",
+           isOver ? "text-over-budget" : diff !== 0 ? "text-on-budget" : "text-muted-foreground"
+         )}
+       >
+         {formatCurrency(Math.abs(diff), currency)}
+         {diff < 0 ? " over" : ""}
+       </TableCell>
+     )
+   }
+   ```
+
+4. **Update DifferenceCell call sites:** In the grouped.map render:
+   - Remove the `const isIncome = type === "income"` line.
+   - Change `<DifferenceCell budgeted={...} actual={...} currency={currency} isIncome={isIncome} />` to `<DifferenceCell budgeted={...} actual={...} currency={currency} type={type} />` in BOTH places (per-item row and group footer).
+
+5. **Remove TierBadge from BudgetDetailPage:** Per research recommendation, remove the tier column from BudgetDetailPage to reduce visual noise and align with CategorySection display. This is Claude's discretion per CONTEXT.md.
+   - Remove the TierBadge component definition from BudgetDetailPage (keep it in TemplatePage where it belongs).
+   - Remove the `<TableHead>{t("categories.type")}</TableHead>` column from the table header.
+   - Remove the `<TableCell><TierBadge tier={item.item_tier} /></TableCell>` from each table row.
+   - Update the TableFooter `colSpan` accordingly: the first footer cell changes from `colSpan={2}` to no colSpan (or `colSpan={1}`), and the last footer cell changes appropriately.
+   - Remove the `Badge` import if no longer used elsewhere in this file.
+
+6. **Group header upgrade:** Replace the dot+h2 pattern in grouped.map with:
+   ```tsx
+   <div
+     className="mb-2 flex items-center gap-3 rounded-sm border-l-4 bg-muted/30 px-3 py-2"
+     style={{ borderLeftColor: categoryColors[type] }}
+   >
+     <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+   </div>
+   ```
+
+7. **Fix locale for headingLabel:** Update the `headingLabel` function. Destructure `i18n` from `useTranslation`: change `const { t } = useTranslation()` to `const { t, i18n } = useTranslation()`. Then:
+   ```tsx
+   function headingLabel(): string {
+     if (!budget) return ""
+     const [year, month] = budget.start_date.split("-").map(Number)
+     return new Intl.DateTimeFormat(i18n.language, { month: "long", year: "numeric" }).format(
+       new Date(year ?? 0, (month ?? 1) - 1, 1)
+     )
+   }
+   ```
+
+8. **Fix overall totals section:** The overall totals box at the bottom uses hardcoded `text-green-600`/`text-red-600`. Replace with semantic tokens:
+   ```tsx
+   <p
+     className={cn(
+       "text-lg font-semibold tabular-nums",
+       totalBudgeted - totalActual >= 0 ? "text-on-budget" : "text-over-budget"
+     )}
+   >
+   ```
+   This replaces the inline ternary with `text-green-600 dark:text-green-400` / `text-red-600 dark:text-red-400`.
+
+9. **Fix group footer "Total" label:** The group footer currently has hardcoded English ` Total`:
+   ```tsx
+   <TableCell colSpan={2} className="font-medium">
+     {t(`categories.types.${type}`)} Total
+   </TableCell>
+   ```
+   Replace with i18n:
+   ```tsx
+   <TableCell className="font-medium">
+     {t("budgets.total", { label: t(`categories.types.${type}`) })}
+   </TableCell>
+   ```
+   The `budgets.total` key was added in Task 1's i18n step: `"total": "{{label}} Total"` / `"total": "{{label}} Gesamt"`.
+
+10. **Replace header with PageShell:** Replace the back link + header section. Keep the back link as a child of PageShell:
+    ```tsx
+    <PageShell
+      title={headingLabel()}
+      action={
+        <Button onClick={openAddDialog} size="sm">
+          <Plus className="mr-1 size-4" />
+          {t("budgets.addItem")}
+        </Button>
+      }
+    >
+      <Link
+        to="/budgets"
+        className="-mt-4 inline-flex items-center gap-1 text-sm text-muted-foreground hover:text-foreground"
+      >
+        <ArrowLeft className="size-4" />
+        {t("budgets.title")}
+      </Link>
+      {/* rest of content */}
+    </PageShell>
+    ```
+    The `-mt-4` on the back link compensates for PageShell's `gap-6`, pulling it closer to the header.
+
+11. **Skeleton loading:** Replace `if (loading) return null` with:
+    ```tsx
+    if (loading) return (
+      <PageShell title="">
+        <div className="space-y-6">
+          <Skeleton className="h-4 w-24" />
+          {[1, 2, 3].map((i) => (
+            <div key={i} className="space-y-2">
+              <div className="flex items-center gap-3 rounded-sm border-l-4 border-muted bg-muted/30 px-3 py-2">
+                <Skeleton className="h-4 w-28" />
+              </div>
+              {[1, 2].map((j) => (
+                <div key={j} className="flex items-center gap-4 px-4 py-2.5 border-b border-border">
+                  <Skeleton className="h-4 w-32" />
+                  <Skeleton className="ml-auto h-4 w-20" />
+                  <Skeleton className="h-4 w-20" />
+                  <Skeleton className="h-4 w-16" />
+                </div>
+              ))}
+            </div>
+          ))}
+          <Skeleton className="h-20 w-full rounded-md" />
+        </div>
+      </PageShell>
+    )
+    ```
+
+**IMPORTANT VERIFICATION after changes:** Ensure NO instances of `text-green-600`, `text-red-600`, `text-green-400`, or `text-red-400` remain in BudgetDetailPage.tsx. All color coding must use `text-over-budget`, `text-on-budget`, or `text-muted-foreground`.

+  </verify>
+  <done>BudgetDetailPage uses semantic color tokens (text-over-budget/text-on-budget) with zero instances of text-green-600 or text-red-600. Direction-aware diff logic handles all 6 category types correctly (spending types over when actual > budgeted, income/saving/investment over when actual < budgeted). Left-border accent group headers replace dot headers. Tier badge column removed for cleaner display. Locale-aware month heading. Skeleton loading state. PageShell wraps the page. Overall totals box uses semantic tokens. Group footer total label uses i18n interpolation. Build passes.</done>

+
+**BudgetListPage and BudgetDetailPage upgraded with PageShell, locale-aware Intl.DateTimeFormat month names, semantic color tokens (text-over-budget/text-on-budget), direction-aware diff for all 6 category types, left-border accent group headers, skeleton loading, and i18n translations for month/year/total labels**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-17T15:19:03Z
+- **Completed:** 2026-03-17T15:21:00Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+
+- Eliminated hardcoded English `MONTHS` array and `toLocaleDateString("en")` — both pages now use `Intl.DateTimeFormat(locale)` fed by `i18n.language`
+- Replaced `text-green-600`/`text-red-600`/`text-green-400`/`text-red-400` with `text-on-budget`/`text-over-budget` semantic tokens — zero hardcoded color classes remain
+- Rewrote `DifferenceCell` with `SPENDING_TYPES` + `isSpendingType()` direction-aware logic covering all 6 category types (spending over when actual > budgeted; income/saving/investment over when actual < budgeted)
+- Both pages wrapped in `PageShell` — completing consistent header layout across all 9 app pages
+- `return null` loading states replaced with `PageShell + Skeleton` — no blank screen flash during data load
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Upgrade BudgetListPage with PageShell, locale-aware months, skeleton, and i18n labels** - `89dd3de` (feat)
+2. **Task 2: Upgrade BudgetDetailPage with semantic tokens, direction-aware diff, PageShell, group headers, and skeleton** - `24d071c` (feat)
+
+**Plan metadata:** `1e61b88` (docs: complete plan)
+
+## Files Created/Modified
+
+- `src/pages/BudgetListPage.tsx` - PageShell, locale-aware monthItems useMemo, Skeleton loading, i18n month/year Labels, budgetLabel accepts locale param
+- `src/pages/BudgetDetailPage.tsx` - PageShell, semantic tokens, direction-aware DifferenceCell, left-border group headers, locale-aware headingLabel, Skeleton loading, TierBadge removed, budgets.total i18n
+- `src/i18n/en.json` - Added budgets.month, budgets.year, budgets.total keys
+- `src/i18n/de.json` - Added budgets.month (Monat), budgets.year (Jahr), budgets.total (Gesamt)
+
+## Decisions Made
+
+- **Direction-aware diff replicated from CategorySection:** Same `SPENDING_TYPES` array pattern as `CategorySection.tsx` ensures consistent diff direction across dashboard and budget detail views
+- **TierBadge column removed:** Plan specification to remove tier column for cleaner display — reduces visual noise, aligns with CategorySection which doesn't show tier badges
+- **i18n keys added for month/year/total:** Enables full German locale support in budget dialogs and footer totals; `{{label}} Total` / `{{label}} Gesamt` pattern uses i18next interpolation
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+- 6 pre-existing lint errors in unrelated files (MonthNavigator.tsx, badge.tsx, button.tsx, sidebar.tsx, useBudgets.ts) — pre-existing, documented in STATE.md, not caused by this plan's changes
+- `return null` in BudgetDetailPage.tsx line 492 is inside a JSX render callback (`CATEGORY_TYPES.map()`), not a loading state — plan's verification intent (no loading-state nulls) is fully satisfied
+
+## Next Phase Readiness
+
+- All 4 phases of the design consistency roadmap are complete
+- All 9 pages use consistent PageShell layout
+- All semantic color tokens applied throughout the app
+- German locale fully supported on all pages including budget dialogs

+# Phase 4: Full-App Design Consistency - Context
+
+**Gathered:** 2026-03-17
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Apply the design system established in Phases 1-3 to every page in the app, delivering a consistent visual experience across all navigation paths. This covers all 9 pages: Login, Register, Categories, Template, Budget List, Budget Detail, Quick Add, Settings, and Dashboard. All pages adopt PageShell, consistent card/typography/color token usage, and full i18n coverage including German locale. No new features or backend changes.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Auth pages (Login & Register)
+- Solid muted background color behind the centered card (not plain white, not gradient)
+- Card accent styling: Claude's discretion on whether top border, shadow, or ring treatment
+- App icon/logo above the title text for brand presence (icon asset or emoji/Lucide placeholder)
+- OAuth buttons (Google, GitHub) get provider SVG icons next to text labels
+- Pages remain standalone centered layout (outside AppLayout sidebar)
+
+### BudgetDetail category sections
+- Migrate to semantic color tokens (`--color-on-budget`, `--color-over-budget`) replacing hardcoded `text-green-600`/`text-red-600`
+- Adopt direction-aware diff logic from Phase 3: spending types over when actual > budgeted, income under-earned when actual < budgeted
+- Visual style upgrade: left-border accent + badge chips to match dashboard CategorySection appearance
+- Collapsible behavior vs always-expanded: Claude's discretion based on editing context
+- Tier badges (Fixed/Variable/One-off): Claude's discretion on keep vs remove
+- Overall totals box: Claude's discretion on whether to use StatCards or keep as styled box
+
+### Category group headers (Categories, Template, QuickAdd pages)
+- Group header styling upgrade: Claude's discretion on matching full dashboard CategorySection style (left-border card) vs enhanced dot style (larger dot, bolder label)
+- Template group totals placement (header badge vs table footer): Claude's discretion
+- BudgetList enrichment (card per budget vs table): Claude's discretion
+- Settings card structure (single vs multiple cards): Claude's discretion
+
+### Page descriptions & polish
+- Page descriptions via PageShell description prop: Claude's discretion per-page on whether subtitle adds value
+- Empty states: Claude's discretion on whether to add icon/illustration treatment or keep text-only
+- Loading states: Add skeleton placeholders for all pages (replacing current `return null` loading states)
+- i18n: Locale-aware month formatting using `Intl.DateTimeFormat` with user's locale (e.g., "Marz 2026" in German)

+## Existing Code Insights
+
+### Reusable Assets
+- `PageShell` (components/shared/PageShell.tsx): Title + optional description + CTA slot — ready to adopt on all authenticated pages
+- `CategorySection` (components/dashboard/): Left-border accent + badge chips + collapsible — potential reuse/adaptation for BudgetDetail and CRUD pages
+- `StatCard` / `SummaryStrip` (components/dashboard/): KPI cards — potential reuse on BudgetDetail totals
+- `DashboardSkeleton` (components/dashboard/): Pattern reference for building page-specific skeletons
+- `Skeleton` (ui/skeleton.tsx): shadcn primitive for building loading placeholders
+- `Badge` (ui/badge.tsx): Already used on Categories/Template/BudgetDetail for tier indicators
+- `Card` / `CardHeader` / `CardContent` (ui/card.tsx): Available for wrapping sections
+- `categoryColors` / `categoryLabels` (lib/palette.ts): CSS variable map and labels for all 6 types
+- `formatCurrency` (lib/format.ts): Currency formatting — already in use, no changes needed
+- `Separator` (ui/separator.tsx): Available for visual section breaks
+
+### Established Patterns
+- Two-tier OKLCH color pattern: text ~0.55 lightness, fills ~0.65-0.70 (Phase 1)
+- Semantic status tokens: `--color-over-budget` (red), `--color-on-budget` (green) (Phase 1)
+- Components accept `t()` as prop to stay presentational (Phase 1)
+- Direction-aware diff logic: spending over when actual > budget, income/savings over when actual < budget (Phase 3)
+- Left-border accent card with badge chips for category group headers (Phase 3)
+- `useMemo` hooks before early returns for Rules of Hooks compliance (Phase 2)
+- Inline editing with InlineEditCell pattern (BudgetDetailPage)
+- Category grouping: `CATEGORY_TYPES.map(type => items.filter(by type))` pattern used across Categories, Template, BudgetDetail
+
+### Integration Points
+- All authenticated pages render inside `AppLayout` > `SidebarInset` > `<main>` > `<Outlet>` — PageShell wraps content inside Outlet
+- Login/Register are standalone routes outside AppLayout — background treatment applies to their root div
+- `App.tsx`: Route definitions — no changes needed, just page component internals
+- i18n: `en.json` and `de.json` need new keys for page descriptions, loading states, and localized month names
+- `Intl.DateTimeFormat`: Available natively for locale-aware month formatting — replaces hardcoded English month arrays in BudgetListPage

+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+**Auth pages (Login & Register):**
+- Solid muted background color behind the centered card (not plain white, not gradient)
+- Card accent styling: Claude's discretion on whether top border, shadow, or ring treatment
+- App icon/logo above the title text for brand presence (icon asset or emoji/Lucide placeholder)
+- OAuth buttons (Google, GitHub) get provider SVG icons next to text labels
+- Pages remain standalone centered layout (outside AppLayout sidebar)
+
+**BudgetDetail category sections:**
+- Migrate to semantic color tokens (`--color-on-budget`, `--color-over-budget`) replacing hardcoded `text-green-600`/`text-red-600`
+- Adopt direction-aware diff logic from Phase 3: spending types over when actual > budgeted, income under-earned when actual < budgeted
+- Visual style upgrade: left-border accent + badge chips to match dashboard CategorySection appearance
+- Collapsible behavior vs always-expanded: Claude's discretion based on editing context
+- Tier badges (Fixed/Variable/One-off): Claude's discretion on keep vs remove
+- Overall totals box: Claude's discretion on whether to use StatCards or keep as styled box
+
+**Category group headers (Categories, Template, QuickAdd pages):**
+- Group header styling upgrade: Claude's discretion on matching full dashboard CategorySection style (left-border card) vs enhanced dot style (larger dot, bolder label)
+- Template group totals placement (header badge vs table footer): Claude's discretion
+- BudgetList enrichment (card per budget vs table): Claude's discretion
+- Settings card structure (single vs multiple cards): Claude's discretion
+
+**Page descriptions & polish:**
+- Page descriptions via PageShell description prop: Claude's discretion per-page on whether subtitle adds value
+- Empty states: Claude's discretion on whether to add icon/illustration treatment or keep text-only
+- Loading states: Add skeleton placeholders for all pages (replacing current `return null` loading states)
+- i18n: Locale-aware month formatting using `Intl.DateTimeFormat` with user's locale (e.g., "Marz 2026" in German)
+- All hardcoded English strings (month names, "Month"/"Year" labels) must get i18n keys in both en.json and de.json

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|-----------------|
+| UI-DESIGN-01 | All 9 pages use PageShell with consistent typography, card style, and color token usage | PageShell already exists in shared/PageShell.tsx — 7 of 9 pages need it wired in; DashboardPage already uses it |
+| UI-AUTH-01 | Login and Register pages have refreshed visual design matching dashboard card/color patterns | Both pages use plain `bg-background` — need `bg-muted` background + card accent treatment + app logo/icon |
+| UI-CATEGORIES-01 | Categories page group headers upgraded to match design system | CategoriesPage uses plain dot+label headers — upgrade to left-border card or enhanced dot style |
+| UI-TEMPLATE-01 | Template page group headers upgraded and totals displayed | TemplatePage uses same plain dot+label headers as Categories |
+| UI-BUDGETS-01 | BudgetDetail displays category groups with color-accented cards and semantic diff tokens | BudgetDetailPage uses hardcoded `text-green-600`/`text-red-600` + plain dot headers + no semantic tokens |
+| UI-QUICKADD-01 | Quick Add page uses PageShell with consistent styling | QuickAddPage has no group headers (flat list) — primarily needs PageShell + possible restructure |
+| UI-SETTINGS-01 | Settings page uses PageShell with consistent styling | SettingsPage has no PageShell, has a Card already but redundant h1+CardTitle |
+| UI-RESPONSIVE-01 | Navigating between any two pages produces no jarring visual discontinuity | All pages need consistent gap/spacing, same PageShell header heights, same font sizing |
+</phase_requirements>
+
+---
+
+## Summary
+
+Phase 4 is a pure polish and pattern-application phase — no new features, no backend changes. The design system (OKLCH color tokens, semantic status tokens, CategorySection component, PageShell) is fully established in Phases 1–3. The work is applying it uniformly to all 9 pages.
+
+The current state has a clear divide: DashboardPage is the polished reference, and all other authenticated pages are functional-but-unstyled first-drafts. Seven pages have inline `<h1>` headings instead of PageShell. Six pages return `null` while loading instead of showing skeletons. BudgetDetailPage has hardcoded Tailwind color classes (`text-green-600`, `text-red-600`) that bypass the established semantic token system. Auth pages have a plain `bg-background` root div where the design spec calls for `bg-muted`.
+
+The `favicon.svg` in `/public/` is a real stylized lightning-bolt SVG with the app's purple brand color (`#863bff`) — this is the logo asset to use above the auth card title. No additional icon asset is needed.
+
+There is no test infrastructure in this project (no test files, no test framework configured). `nyquist_validation` is enabled in config.json, so this section must be addressed, but with a note that all validation is manual/visual for a UI-only phase.
+
+**Primary recommendation:** Treat this phase as 9 small, sequential page upgrades. Apply PageShell + skeleton + i18n cleanup as a checklist across each page. Use direct codebase inspection — not external research — as the source of truth.

+## Standard Stack
+
+### Core (already installed — no new dependencies needed)
+
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| React | 19.2.4 | Component rendering | Project foundation |
+| react-i18next | 16.5.8 | i18n translation hook `useTranslation` | Already in use project-wide |
+| Tailwind CSS | 4.2.1 | Utility classes | Project styling system |
+| shadcn/ui primitives | (radix-ui 1.4.3) | Card, Badge, Skeleton, Button, etc. | Already installed and used |
+| lucide-react | 0.577.0 | Icons (including logo placeholder) | Already in use project-wide |
+
+### Supporting
+
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| `Intl.DateTimeFormat` | Native browser API | Locale-aware month/year formatting | Replace hardcoded English month arrays in BudgetListPage and BudgetDetailPage |
+
+### Alternatives Considered
+
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| `Intl.DateTimeFormat` | date-fns or dayjs | No new dependency needed — native API does exactly what's required (month+year locale formatting) |
+| Lucide `Zap` icon for auth logo | Custom SVG import from `/public/favicon.svg` | The favicon.svg is a real brand asset — using an `<img src="/favicon.svg">` is simpler and more authentic than a Lucide icon |
+
+**Installation:** No new packages needed.

+```
+
+### Pattern 1: PageShell Adoption (7 pages)
+
+**What:** Replace each page's inline `<div>` + `<h1>` + action button header with `<PageShell title={t("...")} action={<Button>}>`
+
+**When to use:** Every authenticated page (all pages inside AppLayout)
+
+**Current pattern to replace:**
+```tsx
+// Before — every CRUD page looks like this:
+<div>
+  <div className="mb-6 flex items-center justify-between">
+    <h1 className="text-2xl font-semibold">{t("categories.title")}</h1>
+    <Button onClick={openCreate} size="sm">...</Button>
+  </div>
+  {/* content */}
+</div>
+```
+
+**Target pattern:**
+```tsx
+// After — consistent with DashboardPage
+import { PageShell } from "@/components/shared/PageShell"
+
+return (
+  <PageShell
+    title={t("categories.title")}
+    description={t("categories.description")}  // optional
+    action={<Button onClick={openCreate} size="sm">...</Button>}
+  >
+    {/* content */}
+  </PageShell>
+)
+```
+
+**Note:** SettingsPage already has a `Card` inside — the redundant `<h1>` heading above the card should be removed when wrapping with PageShell. The CardTitle inside can become the section header.
+
+### Pattern 2: Skeleton Loading States (6 pages)
+
+**What:** Replace `if (loading) return null` with a page-appropriate skeleton
+
+**Current state:** 6 pages use `return null` as loading state:
+- CategoriesPage — `if (loading) return null`
+- TemplatePage — `if (loading) return null`
+- BudgetListPage — `if (loading) return null`
+- BudgetDetailPage — `if (loading) return null`
+- QuickAddPage — `if (loading) return null`
+- SettingsPage — `if (loading) return null`
+
+**DashboardSkeleton as pattern reference:**
+```tsx
+// Source: src/components/dashboard/DashboardSkeleton.tsx
+// Pattern: Skeleton primitive wrapped in Card layout to mirror real content shape
+import { Skeleton } from "@/components/ui/skeleton"
+import { Card, CardContent, CardHeader } from "@/components/ui/card"
+
+// Table page skeleton (Categories, Template, BudgetDetail, QuickAdd):
+function TablePageSkeleton() {
+  return (
+    <div className="space-y-4">
+      {/* Mimics group header shape */}
+      <div className="flex items-center gap-3 rounded-md border-l-4 border-muted bg-card px-4 py-3">
+        <Skeleton className="h-4 w-32" />
+      </div>
+      {/* Mimics table rows */}
+      {[1, 2, 3].map((i) => (
+        <div key={i} className="flex items-center gap-4 px-4 py-2">
+          <Skeleton className="h-4 w-40" />
+          <Skeleton className="ml-auto h-4 w-20" />
+        </div>
+      ))}
+    </div>
+  )
+}
+```
+
+**Rule of Hooks compliance:** Skeletons must be returned AFTER all hooks have been called. The existing pages already follow this — `return null` always appears after all `useState`/`useEffect`/derived-state code.
+
+### Pattern 3: Auth Page Redesign
+
+**What:** Upgrade Login and Register from plain `bg-background` to brand-presence auth layout
+
+**Current state:**
+```tsx
+// LoginPage.tsx (line 35) — plain white background
+<div className="flex min-h-screen items-center justify-center bg-background p-4">
+  <Card className="w-full max-w-sm">
+    <CardHeader className="text-center">
+      <CardTitle className="text-2xl">{t("app.title")}</CardTitle>
+    </CardHeader>
+```
+
+**Target pattern:**
+```tsx
+// Muted background + logo above title + card accent
+<div className="flex min-h-screen items-center justify-center bg-muted/60 p-4">
+  <Card className="w-full max-w-sm border-t-4 border-t-primary">
+    <CardHeader className="text-center">
+      <img src="/favicon.svg" alt="SimpleFinanceDash" className="mx-auto mb-3 size-10" />
+      <CardTitle className="text-2xl">{t("app.title")}</CardTitle>
+    </CardHeader>
+```
+
+**OAuth provider icons:** Add SVG inline icons for Google and GitHub next to button text labels. Standard approach is a small inline SVG (16x16) or use a well-known path. Both Google G and GitHub Octocat have canonical simple SVG marks.
+
+### Pattern 4: BudgetDetail — Semantic Token Migration
+
+**What:** Replace DifferenceCell's hardcoded color classes with semantic tokens
+
+**Current problem code (BudgetDetailPage.tsx lines 169–173):**
+```tsx
+const color =
+  diff > 0
+    ? "text-green-600 dark:text-green-400"
+    : diff < 0
+      ? "text-red-600 dark:text-red-400"
+      : "text-muted-foreground"
+```
+
+**Correct pattern (matching CategorySection):**
+```tsx
+// Use the same tokens established in Phase 1
+import { cn } from "@/lib/utils"
+
+// isOver uses same direction-aware logic as CategorySection
+const isOver = isSpendingType(type) ? actual > budgeted : actual < budgeted
+const colorClass = isOver ? "text-over-budget" : diff !== 0 ? "text-on-budget" : "text-muted-foreground"
+```
+
+**Note on `text-on-budget` vs `text-muted-foreground`:** The CategorySection uses `text-on-budget` for non-over items in the header but `text-muted-foreground` for non-over item rows in the table body. For consistency, replicate that exact distinction.
+
+### Pattern 5: Group Header Upgrade (CategoriesPage, TemplatePage, BudgetDetailPage)
+
+**Current state:** All three CRUD pages use the same small-dot pattern:
+```tsx
+<div className="mb-2 flex items-center gap-2">
+  <div className="size-3 rounded-full" style={{ backgroundColor: categoryColors[type] }} />
+  <h2 className="text-sm font-medium text-muted-foreground">
+    {t(`categories.types.${type}`)}
+  </h2>
+</div>
+```
+
+**Recommended upgrade (enhanced dot — not full CategorySection card):** For CRUD pages, a full left-border card with collapse is excessive (editing context favors always-expanded). Use a larger dot with bolder label for visual consistency without the overhead:
+```tsx
+<div className="mb-2 flex items-center gap-3 border-l-4 bg-muted/30 px-3 py-2 rounded-sm"
+     style={{ borderLeftColor: categoryColors[type] }}>
+  <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+</div>
+```
+
+This matches the left-border accent visual language without the collapsible trigger complexity. CRUD pages are editing interfaces — always-expanded is correct UX.
+
+### Pattern 6: i18n — Locale-Aware Month Formatting
+
+**What:** Replace hardcoded English month arrays and label strings with `Intl.DateTimeFormat`
+
+**Current problem in BudgetListPage.tsx (lines 36–49):**
+```tsx
+// Hardcoded English month labels
+const MONTHS = [
+  { value: 1, label: "January" },
+  // ... 11 more hardcoded English strings
+]
+```
+And the dialog labels (lines 189, 210): `<Label>Month</Label>` and `<Label>Year</Label>` — hardcoded English.
+
+**Current problem in BudgetDetailPage.tsx (line 279):**
+```tsx
+return date.toLocaleDateString("en", { month: "long", year: "numeric" })
+// Hardcoded "en" locale — always English regardless of user's language setting
+```
+
+**Correct pattern:**
+```tsx
+// Use the i18n hook to get the active locale
+const { i18n } = useTranslation()
+const locale = i18n.language  // "en" or "de"
+
+// Locale-aware month name generation
+const monthOptions = Array.from({ length: 12 }, (_, i) => ({
+  value: i + 1,
+  label: new Intl.DateTimeFormat(locale, { month: "long" }).format(new Date(2000, i, 1)),
+}))
+
+// Locale-aware budget heading
+function budgetHeading(startDate: string, locale: string): string {
+  const [year, month] = startDate.split("-").map(Number)
+  return new Intl.DateTimeFormat(locale, { month: "long", year: "numeric" })
+    .format(new Date(year ?? 0, (month ?? 1) - 1, 1))
+}
+```
+
+**New i18n keys needed for month dialog labels:**
+```json
+// en.json additions
+"budgets": {
+  "month": "Month",
+  "year": "Year"
+}
+
+// de.json equivalents
+"budgets": {
+  "month": "Monat",
+  "year": "Jahr"
+}
+```
+
+### Anti-Patterns to Avoid
+
+- **Returning `null` during loading:** Every page currently does `if (loading) return null` — replace all with skeleton components. This is the most visible UX gap.
+- **Hardcoded locale string `"en"` in `toLocaleDateString`:** BudgetDetailPage line 279 and BudgetListPage's `budgetLabel` helper both force English formatting. Must use `i18n.language` instead.
+- **Inline `<h1>` + action div:** 7 pages duplicate the exact pattern that PageShell was built to replace. Don't leave any of these after this phase.
+- **Hardcoded `text-green-600` / `text-red-600`:** BudgetDetailPage `DifferenceCell` component bypasses the semantic token system established in Phase 1. This breaks dark mode and design consistency.
+- **Double heading in SettingsPage:** SettingsPage has both `<h1 className="mb-6 text-2xl font-semibold">` and `<CardTitle>` both showing "Settings" — wrap with PageShell and remove the redundant `h1`.
+
+---
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Locale-aware month names | Custom `MONTHS` array with translations | `Intl.DateTimeFormat` | Already returns localized month names in any locale; zero maintenance |
+| Loading placeholder UI | Custom spinners or CSS animations | `Skeleton` from `ui/skeleton.tsx` | Already installed, same design language as DashboardSkeleton |
+| Auth page logo | New SVG asset or Lucide icon | `/public/favicon.svg` via `<img>` | Brand asset already exists, consistent with browser tab favicon |
+| Direction-aware diff logic | New computation function | Extract from `CategorySection.tsx` (or import `computeDiff`) | Logic is already correct and battle-tested in Phase 3 |
+| Group header card styling | New component | Inline left-border pattern from CategorySection's trigger element | Consistent look without creating a new abstraction |
+
+**Key insight:** This phase adds no new libraries and creates minimal new abstractions. Almost everything needed is already in the codebase.
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: Rules of Hooks — `return null` to Skeleton Migration
+**What goes wrong:** Moving `if (loading) return null` to return a Skeleton component without checking that all hooks come before the condition.
+**Why it happens:** React requires all hooks to be called unconditionally on every render. If `return null` is currently AFTER all hooks, swapping to `return <Skeleton>` is safe. But if any hook was accidentally placed after the loading check, switching breaks the rules.
+**How to avoid:** Verify each page's hook ordering before replacing. In this codebase, all 6 pages that use `return null` have their hooks before the check (confirmed by code inspection). Safe to swap directly.
+**Warning signs:** TypeScript/eslint `react-hooks/rules-of-hooks` lint error.
+
+### Pitfall 2: `i18n.language` vs `navigator.language`
+**What goes wrong:** Using `navigator.language` for locale instead of `i18n.language`, causing month names to display in the system locale rather than the user's chosen app locale.
+**Why it happens:** Both are "the user's language" but they represent different things — system preference vs app preference.
+**How to avoid:** Always use `i18n.language` from `useTranslation()` for `Intl.DateTimeFormat` locale argument. The user's locale preference is stored in their Supabase profile and applied via `i18n.changeLanguage()` in SettingsPage.
+
+### Pitfall 3: SettingsPage Double-Header
+**What goes wrong:** Wrapping SettingsPage in `<PageShell title={t("settings.title")}>` without removing the existing `<h1 className="mb-6 text-2xl font-semibold">`, producing two "Settings" headings.
+**Why it happens:** SettingsPage is the only page that already has a Card structure — it's tempting to just prepend PageShell and leave existing content.
+**How to avoid:** Remove the `<h1>` on line 67 of SettingsPage when adding PageShell.
+
+### Pitfall 4: BudgetDetail DifferenceCell isIncome Logic vs Direction-Aware Logic
+**What goes wrong:** The existing `DifferenceCell` uses a simplified `isIncome` boolean prop. Upgrading to the full direction-aware logic from Phase 3 must be consistent — `saving` and `investment` types should behave like income (under-earned = over-budget), not like expenses.
+**Why it happens:** The existing code only checks `isIncome` (type === "income"), missing saving/investment types.
+**How to avoid:** Use the same `SPENDING_TYPES: CategoryType[] = ["bill", "variable_expense", "debt"]` pattern from `CategorySection.tsx`. Any type NOT in this array uses the income/saving logic.
+**Warning signs:** Savings showing red when you've saved MORE than budgeted.
+
+### Pitfall 5: Auth Card Background Mismatch
+**What goes wrong:** Using `bg-muted` (the Tailwind utility class) which maps to `--color-muted` (oklch 0.95) on top of `bg-background` (oklch 0.98) — the contrast is very subtle. If the wrong token is used, the intended visual separation disappears.
+**Why it happens:** The muted background needs enough contrast to make the white card "float."
+**How to avoid:** Use `bg-muted/60` or `bg-secondary` instead. `--color-secondary` is oklch 0.93 vs card white oklch 1.0 — clearer separation. Or use `bg-muted` with a subtle shadow on the card.
+
+### Pitfall 6: Missing i18n Keys Causing Raw Key Strings
+**What goes wrong:** Adding new translation calls (`t("budgets.month")`) before adding the key to both `en.json` and `de.json` — causes the raw key string to render on screen.
+**Why it happens:** It's easy to forget `de.json` when `en.json` is the primary authoring language.
+**How to avoid:** Always update both files atomically in the same task. The phase success criterion explicitly requires no raw i18n key strings in German locale.
+
+---
+
+## Code Examples
+
+Verified patterns from existing codebase:
+
+### PageShell API (src/components/shared/PageShell.tsx)
+```tsx
+// PageShell signature — already final, no changes needed to the component itself
+interface PageShellProps {
+  title: string
+  description?: string       // optional subtitle below title
+  action?: React.ReactNode   // CTA slot (buttons, etc.)
+  children: React.ReactNode
+}
+
+// Usage (from DashboardPage.tsx — the reference implementation):
+<PageShell
+  title={t("dashboard.title")}
+  action={<MonthNavigator availableMonths={availableMonths} t={t} />}
+>
+  {/* page content */}
+</PageShell>
+```
+
+### Skeleton Primitive (src/components/ui/skeleton.tsx)
+```tsx
+// Available for import in all page skeletons
+import { Skeleton } from "@/components/ui/skeleton"
+
+// Example: table row skeleton (for CategoriesPage, TemplatePage, etc.)
+function TableRowSkeleton() {
+  return (
+    <div className="flex items-center gap-4 px-4 py-2.5 border-b border-border">
+      <Skeleton className="h-4 w-36" />
+      <Skeleton className="h-5 w-16 rounded-full" />
+      <Skeleton className="ml-auto h-7 w-7 rounded-md" />
+    </div>
+  )
+}
+```
+
+### Group Header Upgrade Pattern
+```tsx
+// Upgrade from plain dot to left-border accent header
+// Before (all CRUD pages):
+<div className="mb-2 flex items-center gap-2">
+  <div className="size-3 rounded-full" style={{ backgroundColor: categoryColors[type] }} />
+  <h2 className="text-sm font-medium text-muted-foreground">
+    {t(`categories.types.${type}`)}
+  </h2>
+</div>
+
+// After (enhanced dot — keeps always-expanded for editing context):
+<div
+  className="mb-2 flex items-center gap-3 rounded-sm border-l-4 bg-muted/30 px-3 py-2"
+  style={{ borderLeftColor: categoryColors[type] }}
+>
+  <span className="text-sm font-semibold">{t(`categories.types.${type}`)}</span>
+</div>
+```
+
+### Semantic Token Migration (BudgetDetailPage)
+```tsx
+// Before (hardcoded Tailwind colors — bypasses design tokens):
+const color =
+  diff > 0 ? "text-green-600 dark:text-green-400"
+  : diff < 0 ? "text-red-600 dark:text-red-400"
+  : "text-muted-foreground"
+
+// After (semantic tokens — consistent with CategorySection):
+// SPENDING_TYPES same as in CategorySection.tsx
+const SPENDING_TYPES: CategoryType[] = ["bill", "variable_expense", "debt"]
+function isOver(type: CategoryType, budgeted: number, actual: number): boolean {
+  return SPENDING_TYPES.includes(type) ? actual > budgeted : actual < budgeted
+}
+// In render:
+const over = isOver(type, item.budgeted_amount, item.actual_amount)
+const colorClass = cn(
+  "text-right tabular-nums",
+  over ? "text-over-budget" : diff !== 0 ? "text-on-budget" : "text-muted-foreground"
+)
+```
+
+### Locale-Aware Month Name (replaces hardcoded MONTHS array)
+```tsx
+// In BudgetListPage — replaces the 12-item MONTHS constant:
+const { i18n } = useTranslation()
+const locale = i18n.language  // "en" | "de"
+
+const monthItems = useMemo(
+  () =>
+    Array.from({ length: 12 }, (_, i) => ({
+      value: i + 1,
+      label: new Intl.DateTimeFormat(locale, { month: "long" }).format(
+        new Date(2000, i, 1)
+      ),
+    })),
+  [locale]
+)
+
+// In BudgetDetailPage and BudgetListPage — replaces hardcoded "en" locale:
+function budgetHeading(startDate: string, locale: string): string {
+  const [year, month] = startDate.split("-").map(Number)
+  return new Intl.DateTimeFormat(locale, { month: "long", year: "numeric" }).format(
+    new Date(year ?? 0, (month ?? 1) - 1, 1)
+  )
+}
+```
+
+### Auth Page Redesign Structure
+```tsx
+// LoginPage / RegisterPage root structure
+<div className="flex min-h-screen items-center justify-center bg-muted/60 p-4">
+  <Card className="w-full max-w-sm border-t-4 border-t-primary shadow-lg">
+    <CardHeader className="text-center pb-4">
+      {/* App logo from public/favicon.svg */}
+      <img
+        src="/favicon.svg"
+        alt="SimpleFinanceDash"
+        className="mx-auto mb-3 size-10"
+        aria-hidden
+      />
+      <CardTitle className="text-2xl">{t("app.title")}</CardTitle>
+      <p className="text-sm text-muted-foreground">{t("auth.loginSubtitle")}</p>
+    </CardHeader>
+    {/* ... existing form content ... */}
+  </Card>
+</div>
+```
+
+---
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| No loading state (return null) | Skeleton components | Phase 4 | Users see content-shaped placeholders instead of blank pages |
+| Hardcoded color classes | Semantic CSS tokens | Phase 1 (dashboard), Phase 4 extends to BudgetDetail | Dark mode support, single-source-of-truth for status colors |
+| Hardcoded "en" locale | `i18n.language` locale | Phase 4 | Month names now display in German when locale is "de" |
+| Inline h1 + action div | PageShell component | Phase 4 extends Phase 1's PageShell | Consistent header height and spacing across all pages |
+| Plain auth background | Muted background + brand logo | Phase 4 | Auth pages feel part of the same app, not a generic template |
+
+**Still current (no change needed):**
+- `formatCurrency` — already locale-aware via Intl.NumberFormat (no changes needed)
+- `categoryColors` / `categoryLabels` in palette.ts — complete and correct
+- AppLayout sidebar — no changes needed, routes unchanged
+- `collapsible-open` / `collapsible-close` animations — complete and correct
+
+---
+
+## Open Questions
+
+1. **BudgetDetail: Keep or remove TierBadge?**
+   - What we know: TierBadge shows Fixed/Variable/One-off on each line item. This metadata is useful for planning but adds visual noise when tracking actuals.
+   - What's unclear: Whether the "editing actuals" context of BudgetDetailPage makes the tier less useful than in TemplatePage.
+   - Recommendation: Remove tier column from BudgetDetailPage to reduce visual noise and align with the CategorySection display style (which shows no tier). Keep tier in TemplatePage since it's a planning interface.
+
+2. **BudgetDetail: Collapsible or always-expanded?**
+   - What we know: BudgetDetailPage is an editing interface where users click inline cells to edit actual amounts. Collapsing sections would require an extra click before editing.
+   - What's unclear: Whether the always-expanded view with full left-border card headers is sufficient, or whether the visual match to the dashboard collapsible style is more important.
+   - Recommendation: Always-expanded with left-border headers. The visual upgrade (left-border cards, semantic tokens, badge chips) delivers the design consistency without the UX cost of collapsing an editing interface.
+
+3. **BudgetDetail: StatCards or styled box for overall totals?**
+   - What we know: The current "overall totals" is a `rounded-md border p-4` div with a 3-column grid.
+   - What's unclear: Whether StatCard's Card+CardHeader+CardContent structure adds meaningful value over the existing styled box.
+   - Recommendation: Keep styled box but upgrade to semantic tokens for the difference color. StatCards are designed for KPI highlight panels (like SummaryStrip) — a dense summary row inside a detail page fits better as a styled section.

+
+## Validation Architecture
+
+> `nyquist_validation` is enabled in `.planning/config.json`. However, this phase is 100% visual UI polish — no new logic, no new data flows, no new API calls. There are no automated tests in this project and none of the changes are unit-testable in the traditional sense.
+
+### Test Framework
+| Property | Value |
+|----------|-------|
+| Framework | None — no test framework configured |
+| Config file | None |
+| Quick run command | `bun run build` (TypeScript compile + Vite build — catches type errors) |
+| Full suite command | `bun run build && bun run lint` |
+
+### Phase Requirements → Test Map
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| UI-DESIGN-01 | All 9 pages render with PageShell header | Visual/manual | `bun run build` (no TS errors) | ❌ Wave 0 |
+| UI-AUTH-01 | Auth pages show muted bg + logo + accent card | Visual/manual | `bun run build` | ❌ Wave 0 |
+| UI-CATEGORIES-01 | Categories group headers have left-border accent | Visual/manual | `bun run build` | ❌ Wave 0 |
+| UI-TEMPLATE-01 | Template group headers upgraded | Visual/manual | `bun run build` | ❌ Wave 0 |
+| UI-BUDGETS-01 | BudgetDetail uses semantic tokens, no text-green-600 | `grep` check | `grep -r "text-green-600" src/pages/BudgetDetailPage.tsx \|\| echo "CLEAN"` | ❌ Wave 0 |
+| UI-QUICKADD-01 | QuickAdd page renders PageShell | Visual/manual | `bun run build` | ❌ Wave 0 |
+| UI-SETTINGS-01 | Settings page uses PageShell, no double heading | Visual/manual | `bun run build` | ❌ Wave 0 |
+| UI-RESPONSIVE-01 | No visual discontinuity between pages | Visual/manual | Manual browser navigation | ❌ Wave 0 |
+
+### Sampling Rate
+- **Per task commit:** `bun run build` — TypeScript compile validates no type regressions
+- **Per wave merge:** `bun run build && bun run lint`
+- **Phase gate:** Manual browser review of all 9 pages in English and German locale before `/gsd:verify-work`
+
+### Wave 0 Gaps
+- No test files to create — this phase has no unit-testable logic
+- Recommend a manual checklist in VERIFY.md covering: all 9 pages load without null flash, German locale shows no raw keys, BudgetDetail shows no text-green-600/text-red-600 classes in DevTools
+
+---
+
+## Sources
+
+### Primary (HIGH confidence)
+- Direct codebase inspection of all 9 page files — source of all findings
+- `src/index.css` — confirmed all OKLCH tokens, semantic status tokens, animation tokens
+- `src/i18n/en.json` and `de.json` — confirmed missing keys (month, year, page descriptions)
+- `src/components/shared/PageShell.tsx` — confirmed interface and implementation
+- `src/components/dashboard/CategorySection.tsx` — reference pattern for group headers
+- `src/components/dashboard/DashboardSkeleton.tsx` — reference pattern for skeletons
+- `src/lib/palette.ts` — confirmed `categoryColors` CSS variable map
+- `package.json` — confirmed no test framework is installed
+
+### Secondary (MEDIUM confidence)
+- MDN Web Docs pattern: `Intl.DateTimeFormat` for locale-aware month names — standard browser API, zero risk
+
+### Tertiary (LOW confidence)
+- None
+
+---
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH — no new libraries, all from direct package.json inspection
+- Architecture: HIGH — all patterns derived from existing codebase, not external research
+- Pitfalls: HIGH — all identified from actual code in the repo (specific file + line references)
+- i18n patterns: HIGH — Intl.DateTimeFormat is a stable native API
+
+**Research date:** 2026-03-17
+**Valid until:** Stable — no external dependencies to go stale. Re-verify only if major packages are upgraded.

+
+## Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `TemplatePage.tsx` | 380 | `return null` inside `.map()` callback | INFO | Not a loading state — intentional JSX early return for empty category groups in Select dropdown. Expected and correct. |
+| `BudgetDetailPage.tsx` | 492 | `return null` inside `.map()` callback | INFO | Same pattern — skips empty category groups in Add Item dialog Select. Expected and correct. |
+
+No stub implementations, no TODO/FIXME/placeholder comments, no empty handlers, no loading-state `return null` patterns found in any of the 7 modified page files.
+
+---
+
+## Build Verification
+
+`bun run build` passes cleanly:
+- 2583 modules transformed
+- TypeScript compilation: 0 errors
+- Output: `dist/index.html`, `dist/assets/index-*.css` (58.73 kB), `dist/assets/index-*.js` (1,132.90 kB)
+- Only warning: chunk size advisory (pre-existing, unrelated to Phase 4)
+
+---
+
+## Commit Verification
+
+All 6 task commits documented in SUMMARYs are confirmed present in git history:
+
+| Commit | Plan | Description |
+|--------|------|-------------|
+| `36d068e` | 04-01 Task 1 | feat: redesign LoginPage with brand presence and OAuth icons |
+| `0ff9939` | 04-01 Task 2 | feat: redesign RegisterPage to match LoginPage |
+| `e9497e4` | 04-02 Task 1 | feat: upgrade CategoriesPage and TemplatePage |
+| `ba19c30` | 04-02 Task 2 | feat: upgrade QuickAddPage and SettingsPage |
+| `89dd3de` | 04-03 Task 1 | feat: upgrade BudgetListPage |
+| `24d071c` | 04-03 Task 2 | feat: upgrade BudgetDetailPage |
+
+---
+
+## Notable Design Decisions Verified
+
+1. **TemplatePage mirrored layout** (not PageShell import): Plan 02 explicitly chose `flex flex-col gap-6 > flex items-start justify-between gap-4` to preserve `TemplateName` inline-edit component. Visual result matches PageShell — confirmed in code at lines 242-281.
+
+2. **TierBadge removed from BudgetDetailPage**: `grep TierBadge BudgetDetailPage.tsx` returns 0. Present in TemplatePage as intended.
+
+3. **Settings no double heading**: `grep CardHeader SettingsPage.tsx` returns 0 — `CardHeader` and `CardTitle` fully removed; PageShell provides the sole "Settings" heading.
+
+4. **Direction-aware diff covers all 6 types**: `SPENDING_TYPES = ["bill", "variable_expense", "debt"]` covers 3 spending types; all others (income, saving, investment) use the opposite diff direction — matches Phase 3 `CategorySection.tsx` pattern exactly.
+
+---
+
+## Human Verification Required
+
+### 1. Cross-page visual continuity
+
+**Test:** Navigate Login -> Dashboard -> Categories -> Template -> Budget List -> Budget Detail -> Quick Add -> Settings -> Register
+**Expected:** Consistent header typography (2xl semibold tracking-tight), consistent card styling, consistent muted/on-background color usage, no layout shift when sidebar transitions between pages
+**Why human:** Layout continuity and "feel" of visual consistency across navigation paths cannot be verified by grep or build
+
+### 2. German locale i18n completeness
+
+**Test:** Log in, go to Settings, switch language to Deutsch, then visit every page
+**Expected:** All text in German — nav labels, page titles, action buttons, form labels, month names in budget dialogs showing "Januar/Februar..." (not "January/February"), auth subtitles, error messages
+**Why human:** i18n key presence verified; runtime substitution and any missed keys only visible at runtime
+
+### 3. Auth page visual design
+
+**Test:** Open `/login` and `/register` in browser
+**Expected:** Distinctly muted grey background behind centered card; card has primary purple top border; favicon lightning bolt logo is visible and sized correctly above card title; Google and GitHub buttons show correct SVG icons
+**Why human:** Visual design quality requires human eyeballing
+
+### 4. BudgetDetail semantic color tokens
+
+**Test:** Open a budget detail with items where some categories are over budget and some are under
+**Expected:** Over-budget amounts appear in red using `--color-over-budget` OKLCH token (not hardcoded `text-red-600`); on-budget amounts appear in green using `--color-on-budget`; direction correct by category type
+**Why human:** Semantic token correctness and diff direction require live data and visual inspection
+
+### 5. Responsive layout (UI-RESPONSIVE-01)
+
+**Test:** At 768px browser width, navigate all 9 pages
+**Expected:** Sidebar collapses or shifts; tables have horizontal scroll; no content overflow; PageShell headers remain readable; auth cards remain centered
+**Why human:** Responsive behavior requires browser viewport resizing — cannot be verified by static code analysis
+
+---
+
+## Summary
+
+Phase 4 has achieved its goal. All 22 observable truths have automated verification evidence OR are flagged for human confirmation where visual quality is the measure. The codebase delivers:
+
+- **Auth pages** (2): Fully redesigned with muted background, card accent, brand logo, i18n subtitles, and OAuth icons
+- **CRUD/Settings pages** (4): PageShell headers, left-border accent group headers (Categories, Template), skeleton loading replacing `return null` on all pages, Settings has exactly one heading
+- **Budget pages** (2): PageShell, locale-aware `Intl.DateTimeFormat`, semantic color tokens replacing hardcoded Tailwind classes, direction-aware diff for all 6 category types, group header accents, skeleton loading, i18n month/year/total labels
+- **Build**: Passes without TypeScript errors
+- **All 8 requirement IDs**: Satisfied by the 3 plans
+
+The 5 human verification items are all quality/visual checks — the underlying implementations are confirmed correct by code inspection and build success.

+# Roadmap: SimpleFinanceDash v2.0 — UX Simplification & Design Rework
+
+## Overview
+
+This milestone transforms SimpleFinanceDash from a visually polished but cognitively complex app into a guided, intuitive budgeting experience. Work flows from a global design token rework (sharp edges, clearer pastels) through data safety foundations, a wizard-driven first-run setup, automatic budget creation, and finally a simplified budget view with inline item adding. Every phase delivers a coherent, verifiable capability on top of the fully working v1.0 baseline.
+
+## Phases
+
+**Phase Numbering:**
+- Integer phases (5-9): v2.0 milestone work, continuing from v1.0's Phase 4
+- Decimal phases: Urgent insertions if needed (marked INSERTED)
+
+Decimal phases appear between their surrounding integers in numeric order.
+
+- [ ] **Phase 5: Design System Token Rework** - Replace rounded corners with sharp edges and refine OKLCH pastel tokens across all 9 pages
+- [ ] **Phase 6: Preset Data, First-Run Detection, and DB Safety** - Seed preset library, build first-run hook, and add DB uniqueness constraints that protect against duplicate data
+- [ ] **Phase 7: Setup Wizard** - 3-step first-run wizard with income, pre-filled recurring items, and review — skippable, state-persisted, bilingual
+- [ ] **Phase 8: Auto-Budget Creation** - Auto-create current month's budget from template on dashboard visit, with correct currency and first-creation toast
+- [ ] **Phase 9: Inline Add and Dashboard Simplification** - Replace Quick Add page with inline Sheet panel, simplify dashboard to at-a-glance view, add empty states
+
+## Phase Details
+
+### Phase 5: Design System Token Rework
+**Goal**: Users see a sharp, minimal, clearly pastel UI across every page — the visual foundation that all subsequent phases build on
+**Depends on**: Phase 4 (v1.0 complete)
+**Requirements**: DS-01, DS-02, DS-03
+**Success Criteria** (what must be TRUE):
+  1. Every rounded element across all 9 pages has sharp corners — no pill buttons, no rounded cards, no rounded inputs visible anywhere in the app
+  2. Category color swatches are visibly colorful against white backgrounds — not washed-out or grey-tinted — and still pass WCAG 4.5:1 contrast for text
+  3. Page layouts feel uncluttered — content sections have consistent whitespace gaps and no visual crowding between cards or sections
+  4. A full visual pass of all 9 pages (Dashboard, Budget List, Budget Detail, Template, Categories, Quick Add, Settings, Login, Register) confirms no regressions from token changes
+**Plans**: TBD
+
+### Phase 6: Preset Data, First-Run Detection, and DB Safety
+**Goal**: The data layer is safe and ready — duplicate budget/category writes are impossible at the DB level, and the app correctly identifies first-run users
+**Depends on**: Phase 5
+**Requirements**: AUTO-01, AUTO-03, SETUP-01, SETUP-02
+**Success Criteria** (what must be TRUE):
+  1. Attempting to create two budgets for the same user and month is rejected at the DB level (unique constraint on `budgets(user_id, start_date)`)
+  2. Attempting to create two categories with the same name for the same user is rejected at the DB level (unique constraint on `categories(user_id, name)`)
+  3. All existing v1.0 users have `profiles.setup_completed = true` after the backfill migration runs — they will not be shown the wizard on their next login
+  4. `useFirstRunState` hook returns `true` only for users with zero categories or zero template items — returning `false` for any user with existing data
+  5. `src/data/presets.ts` contains ~15-20 curated budget items with sensible default amounts, grouped by category type, with both English and German i18n translation keys defined
+**Plans**: TBD
+
+### Phase 7: Setup Wizard
+**Goal**: A new user can set up their budget template in under 3 minutes by following a guided 3-step wizard with pre-filled common items and a live running balance
+**Depends on**: Phase 6
+**Requirements**: SETUP-01, SETUP-02, SETUP-03, SETUP-04, SETUP-05
+**Success Criteria** (what must be TRUE):
+  1. A new user (zero categories, zero template items) is automatically redirected to `/setup` on their first login and sees a 3-step wizard: income entry, recurring items selection, and review
+  2. The recurring items step shows ~15-20 pre-filled common items (rent, groceries, car insurance, utilities, etc.) with editable default amounts — user can check or uncheck each
+  3. A "remaining to allocate" balance updates live as items are checked or unchecked in step 2, showing income minus the sum of selected item amounts
+  4. User can click "Skip" on any individual step or "Skip setup" to exit the wizard entirely without creating any data — and lands on the dashboard
+  5. Completing the wizard creates a populated template from selected items — user lands on the dashboard with their template in place, and refreshing the browser mid-wizard restores the wizard at the correct step
+**Plans**: TBD
+
+### Phase 8: Auto-Budget Creation
+**Goal**: Users never manually trigger budget creation — visiting a month for the first time automatically creates their budget from the template, silently and correctly
+**Depends on**: Phase 7
+**Requirements**: AUTO-01, AUTO-02, AUTO-03
+**Success Criteria** (what must be TRUE):
+  1. Navigating to the dashboard for a month that has no budget (but a populated template) creates the budget automatically — no button click or prompt required
+  2. The first time a budget is auto-created in a session, a toast notification appears naming the month and indicating it was created from the template — subsequent months are created silently
+  3. The auto-created budget uses the user's configured currency from their profile settings, not a hardcoded default
+  4. Rapidly navigating between months or opening the dashboard in two tabs does not produce duplicate budget rows
+**Plans**: TBD
+
+### Phase 9: Inline Add and Dashboard Simplification
+**Goal**: Users add one-off items to their budget directly from the budget view, the Quick Add page is gone, and the dashboard shows this month's data at a glance without chart overload
+**Depends on**: Phase 8
+**Requirements**: BV-01, BV-02, BV-03, DASH-01, DASH-02, DASH-03
+**Success Criteria** (what must be TRUE):
+  1. An "Add item" control on the budget detail page opens a Sheet panel showing the category library — user selects a category, enters an amount, and the item appears in the budget without a page navigation
+  2. The Quick Add page is removed from the sidebar navigation — visiting `/quick-add` redirects to `/budgets` instead of showing an error
+  3. The dashboard displays this month's summary cards (income, expenses, balance) with correct totals that match what the user entered in the budget detail page
+  4. The dashboard does not show the 3-column chart grid by default — the primary view is the at-a-glance summary and collapsible category sections
+  5. Empty template, empty dashboard, and empty budget view each show a clear empty state with a visible call-to-action guiding the user to the next step
+**Plans**: TBD

+# Phase 05 Plan 01: Design Token Foundation Summary
+
+**One-liner:** Established sharp-cornered OKLCH pastel design foundation with --radius: 0 cascade, raised fill chroma to 0.22+, deleted redundant chart color vars, and set chart bars to radius={0} with square legend dots.
+
+## Tasks Completed
+
+| Task | Name | Commit | Key Changes |
+|------|------|--------|-------------|
+| 1 | Edit design tokens and add CSS overrides in index.css | 99b5b5f | --radius: 0, chroma 0.22+, deleted chart vars, warmed bg, Recharts/Sonner overrides |
+| 2 | Update chart Bar radius props and remove rounded-full | 4c74dec | SpendBarChart radius={0}x2, IncomeBarChart radius={0}x2, ExpenseDonutChart legend dot square |
+
+## What Was Built
+
+### index.css Changes
+- `--color-background` chroma raised from 0.005 to 0.01 (warmer background)
+- `--color-chart-1` through `--color-chart-5` deleted (6 lines removed — no remaining consumers)
+- All 6 `--color-*-fill` variables raised to chroma 0.22+ for vibrant pastels:
+  - income: 0.19 → 0.22, bill: 0.19 → 0.22, variable-expense: 0.18 → 0.22
+  - debt: 0.20 → 0.23, saving: 0.18 → 0.22, investment: 0.18 → 0.22
+- `--radius` changed from 0.625rem to 0 — cascades sharp corners to all shadcn components
+- `.recharts-rectangle { rx: 0; ry: 0; }` override added (SVG attribute approach)
+- `[data-sonner-toast] { border-radius: 0 !important; }` override added
+
+### Chart Component Changes
+- `SpendBarChart.tsx`: Both `<Bar>` elements changed from `radius={4}` to `radius={0}`
+- `IncomeBarChart.tsx`: Both `<Bar>` elements changed from `radius={[4, 4, 0, 0]}` to `radius={0}`
+- `ExpenseDonutChart.tsx`: Legend color dot span: removed `rounded-full` from className
+
+## Verification
+
+All acceptance criteria confirmed by grep and build:
+- `--radius: 0` present in index.css
+- `--color-chart-1` through `--color-chart-5` absent from src/
+- `radius={0}` present (2 matches each) in SpendBarChart and IncomeBarChart
+- `rounded-full` absent from ExpenseDonutChart
+- `.recharts-rectangle` and `[data-sonner-toast]` present in index.css
+- `bun run build` exits 0 (TypeScript + Vite both pass)
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Known Stubs
+
+None — all token values are real OKLCH colors wired to actual chart and UI components.
+
+## Threat Flags
+
+None — pure CSS/visual changes with no trust boundary impact.
+
+## Self-Check: PASSED
+
+- [x] `src/index.css` exists and contains all required tokens
+- [x] `src/components/dashboard/charts/SpendBarChart.tsx` contains `radius={0}`
+- [x] `src/components/dashboard/charts/IncomeBarChart.tsx` contains `radius={0}`

+# Phase 05 Plan 02: Shared Component Rounding and Spacing Cleanup Summary
+
+Sharp corners enforced across all 5 shared components by removing hardcoded `rounded-*` classes, and page-level spacing upgraded from `gap-6` to `gap-8` in PageShell propagating to all 9 pages.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files Modified |
+|------|------|--------|----------------|
+| 1 | Upgrade PageShell spacing and remove rounded-* from DashboardSkeleton | e8f13c9 | PageShell.tsx, DashboardSkeleton.tsx |
+| 2 | Remove rounded-* from CategorySection, ChartEmptyState, QuickAddPicker | e7282fa | CategorySection.tsx, ChartEmptyState.tsx, QuickAddPicker.tsx |
+
+## Changes Made
+
+### Task 1: PageShell + DashboardSkeleton
+
+**PageShell.tsx**
+- `gap-6` → `gap-8` in the root flex container (line 15) — applies generous section spacing across all 9 pages
+
+**DashboardSkeleton.tsx**
+- Outer flex: `gap-6` → `gap-8`
+- Summary cards grid: `gap-4` → `gap-6`
+- Chart area grid: `gap-6` → `gap-8`
+- Removed `rounded-md` from 3 chart skeleton `<Skeleton>` elements
+- Removed `rounded-md` from collapsible section row `<div>`
+- Removed `rounded-full` from 2 badge `<Skeleton>` elements (2 occurrences via replace_all)
+
+### Task 2: CategorySection + ChartEmptyState + QuickAddPicker
+
+**CategorySection.tsx**
+- Removed `rounded-md` from collapsible trigger `<button>` — sharp left-bordered row maintained via `border-l-4`
+
+**ChartEmptyState.tsx**
+- Removed `rounded-lg` from the dashed-border container div — sharp rectangular empty state
+
+**QuickAddPicker.tsx**
+- Removed `rounded-sm` from picker item `<button>` elements in the popover list
+- Removed `rounded-full` from the category type dot indicator `<div>`
+

+# Phase 5: Design System Token Rework - Context
+
+**Gathered:** 2026-04-20
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Users see a sharp, minimal, clearly pastel UI across every page — the visual foundation that all subsequent phases build on. This phase modifies design tokens (CSS variables), adjusts spacing utilities across all 9 pages, and overrides third-party component styles. No new features, no new components — purely visual token and spacing changes.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Corner Radius Strategy
+- All elements get 0px border radius — truly sharp corners everywhere
+- Implementation via single `--radius: 0` token change in `src/index.css` (cascades to all shadcn components)
+- No exceptions for avatars, badges, or any element
+- Third-party components (Recharts bars, Sonner toasts) overridden via CSS selectors to force 0 radius
+
+### Pastel Color Refinement
+- Increase chroma on category fill colors to 0.22+ for visible colorful pop against white backgrounds
+- Keep the two-tier color system: text colors at ~0.55L for WCAG 4.5:1 contrast, fill colors lighter/more saturated
+- Slightly warm the base UI colors: background chroma from 0.005→0.01 for subtle warmth
+- Align chart colors with category fill tokens directly — remove separate `--color-chart-*` variables and use `--color-*-fill` tokens in charts
+
+### Spacing & Layout Strategy
+- Increase section gaps: gap-4→gap-6, gap-6→gap-8 across all pages
+- Increase card internal padding: p-4→p-6 for breathing room
+- Keep existing max-w-7xl container constraint
+- Standardize all page headers to mb-6 + section gaps to gap-8 for consistent rhythm
+
+### Claude's Discretion
+- Exact OKLCH chroma/lightness values for category fills (as long as they're 0.22+ chroma and pass WCAG)
+- Order of page updates during implementation
+- Whether to create a spacing utility class or apply changes inline
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `src/index.css` — single file with all design tokens (`@theme inline` block), `--radius: 0.625rem` is the token to change
+- `src/lib/palette.ts` — category color references using CSS variables (no changes needed, references tokens)
+- shadcn/ui components in `src/components/ui/` — all use `rounded-*` classes that derive from `--radius`
+
+### Established Patterns
+- OKLCH color system already in place with hue-based category differentiation
+- Two-tier category colors: text (L=0.55, C=0.16-0.18) and fill (L=0.65-0.70, C=0.18-0.20)
+- Tailwind CSS 4 with `@theme inline` for CSS variable definitions
+- 71 occurrences of `rounded`/`radius` across 27 source files
+
+### Integration Points
+- `src/index.css` `--radius` token controls all shadcn component rounding
+- Chart components (`SpendBarChart`, `IncomeBarChart`, `ExpenseDonutChart`) reference `--color-chart-*` variables
+- 9 pages to audit: Dashboard, BudgetList, BudgetDetail, Template, Categories, QuickAdd, Settings, Login, Register
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Success criteria explicitly requires visual pass of all 9 pages confirming no regressions
+- Category color swatches must be "visibly colorful against white backgrounds" — not washed-out
+- "No pill buttons, no rounded cards, no rounded inputs visible anywhere"
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+None — discussion stayed within phase scope

+
+### `src/components/dashboard/charts/ExpenseDonutChart.tsx` (component, transform)
+
+**Analog:** self — already uses `var(--color-${entry.type}-fill)` pattern throughout.
+
+**The one hardcoded `rounded-full`** (line 141):
+
+```tsx
+/* Before */

+/>
+```
+
+**Changes to make in this file:**
+- Line 141: remove `rounded-full` from className string.
+- No `ChartConfig` changes needed — `ExpenseDonutChart` builds its config dynamically from data using `var(--color-${entry.type}-fill)` (lines 47-51), which is already the correct post-rework pattern.

+
+### `src/components/shared/PageShell.tsx` (component, layout)
+
+**Current spacing** (line 15):
+
+```tsx
+<div className="flex flex-col gap-6">   /* → gap-8 */
+```
+
+**Changes to make in this file:**
+- Line 15: `gap-6` → `gap-8`

+

+
+## Shared Patterns
+
+### Pattern A: `@theme inline` Token Edit (CSS variable cascade)
+
+**Source:** `src/index.css` lines 4-79
+**Apply to:** `src/index.css` only — single source of truth
+**Rule:** All shadcn `rounded-*` utility classes (rounded-md, rounded-sm, rounded-lg, rounded-xl) derive from `--radius`. Setting `--radius: 0` makes them all 0px automatically. Only `rounded-full` (9999px) is immune.
+
+```css
+/* The pattern: edit token value, cascade propagates everywhere */
+@theme inline {
+  --radius: 0;  /* single edit cascades to all shadcn components */
+}
+```
+
+### Pattern B: Hardcoded `rounded-full` Removal (critical pitfall)
+
+**Source:** Every page and component file listed in RESEARCH.md inventory
+**Apply to:** All 17 `rounded-full` class occurrences across 8 files
+**Rule:** `rounded-full` = `border-radius: 9999px` — hardcoded, NOT derived from `--radius`. Must be removed manually from every occurrence.
+
+```tsx
+/* Before — still circular after --radius: 0 */
+<Skeleton className="h-5 w-16 rounded-full" />
+<span className="inline-block size-3 shrink-0 rounded-full" ... />
+<div className="size-2 rounded-full" ... />
+
+/* After — becomes square from --radius: 0 */
+<Skeleton className="h-5 w-16" />
+<span className="inline-block size-3 shrink-0" ... />
+<div className="size-2" ... />
+```
+
+### Pattern C: CSS Override for Third-Party Radius
+
+**Source:** To be added to `src/index.css` after `@layer base` block
+**Apply to:** Recharts bars (`SpendBarChart`, `IncomeBarChart`) and Sonner toasts
+**Rule:** Recharts renders bars as `<rect rx="4" ry="4">` SVG — not CSS. Must change `radius` prop directly AND add CSS override. Sonner wires `--border-radius: var(--radius)` (confirmed at `sonner.tsx` line 28) — should auto-propagate, but add CSS override as safety net.
+
+```css
+/* Add to src/index.css after the @layer base block */
+
+/* Recharts: SVG rect elements for bar charts */
+.recharts-rectangle {
+  rx: 0;
+  ry: 0;
+}
+
+/* Sonner: toast container — safety net if var(--radius) cascade insufficient */
+[data-sonner-toast] {
+  border-radius: 0 !important;
+}
+```
+
+**Note:** Sonner's `sonner.tsx` already passes `"--border-radius": "var(--radius)"` as an inline style (line 28). When `--radius: 0`, this should cascade automatically. The CSS override is a safety net only — verify in browser after token change before deciding if it is needed.
+
+### Pattern D: Group Heading Div (shared across 5 files)
+
+**Source:** `src/pages/CategoriesPage.tsx` line 134, `BudgetDetailPage.tsx` line 353, `TemplatePage.tsx` line 292 — all structurally identical
+**Apply to:** CategoriesPage, BudgetDetailPage, TemplatePage, CategorySection, DashboardSkeleton row
+
+```tsx
+/* Pattern: border-l-4 accent bar heading — remove rounded-sm entirely */
+<div
+  className="mb-2 flex items-center gap-3 border-l-4 bg-muted/30 px-3 py-2"
+  style={{ borderLeftColor: categoryColors[type] }}
+>
+  <span className="text-sm font-semibold">{label}</span>
+</div>
+```
+
+### Pattern E: Spacing Upgrade Map
+
+**Source:** `src/pages/DashboardPage.tsx` lines 186, 207; `src/components/shared/PageShell.tsx` line 15
+**Apply to:** All 9 pages and PageShell
+
+```
+PageShell.tsx line 15:     gap-6      → gap-8      (header-to-content gap)
+DashboardPage.tsx line 186: space-y-6 → space-y-8  (section rhythm)
+DashboardPage.tsx line 207: gap-6     → gap-8      (chart grid)
+DashboardSkeleton.tsx line 22: gap-4  → gap-6      (summary cards grid)
+DashboardSkeleton.tsx line 29: gap-6  → gap-8      (chart grid skeleton)
+CategoriesPage.tsx line 98:  space-y-6 → space-y-8  (skeleton wrapper)
+CategoriesPage.tsx line 130: space-y-6 → space-y-8  (main content)
+TemplatePage.tsx line 247:   space-y-6 → space-y-8  (skeleton wrapper)
+TemplatePage.tsx line 268:   gap-6     → gap-8      (self-managed header flex)
+TemplatePage.tsx line 287:   space-y-6 → space-y-8  (main content)
+BudgetDetailPage.tsx:        verify no space-y-6/gap-6 remain after existing space-y-8 at line 338
+SettingsPage.tsx line 87:    space-y-4 → space-y-6  (CardContent internal)
+```
+
+### Pattern F: `ChartConfig` Token Reference (no `--color-chart-*`)
+
+**Source:** `src/components/dashboard/charts/IncomeBarChart.tsx` lines 26-29
+**Apply to:** Any future chart components — `SpendBarChart` and `IncomeBarChart` require no ChartConfig change
+**Rule:** After deleting `--color-chart-*` from `index.css`, all chart color references must use `--color-*-fill` tokens.
+
+```tsx
+/* Correct pattern post-rework — reference fill tokens directly */
+const chartConfig = {
+  budgeted: { label: "Budgeted", color: "var(--color-budget-bar-bg)" },
+  actual: { label: "Actual", color: "var(--color-income-fill)" },
+} satisfies ChartConfig
+```

+
+## Implementation Wave Order
+
+Per RESEARCH.md recommendation (planner reference):
+
+**Wave 1 — Token edit only** (`src/index.css`)
+- Change `--radius: 0`
+- Raise `--color-*-fill` chroma values to 0.22+
+- Warm `--color-background` chroma 0.005 → 0.01
+- Delete `--color-chart-1` through `--color-chart-5`
+- Add `.recharts-rectangle` and `[data-sonner-toast]` CSS overrides
+
+**Wave 2 — Chart component updates** (2 files)
+- `SpendBarChart.tsx`: `radius={4}` → `radius={0}` (x2 Bar props)
+- `IncomeBarChart.tsx`: `radius={[4, 4, 0, 0]}` → `radius={0}` (x2 Bar props)
+- `ExpenseDonutChart.tsx`: remove `rounded-full` from legend span (line 141)
+
+**Wave 3 — Page and shared component sweep** (12 files)
+- `PageShell.tsx`: `gap-6` → `gap-8`
+- `DashboardSkeleton.tsx`: remove 5 `rounded-*` classes, upgrade 3 spacing values
+- `CategorySection.tsx`: remove `rounded-md` from trigger button
+- `ChartEmptyState.tsx`: remove `rounded-lg` from empty state div
+- `QuickAddPicker.tsx`: remove 2 `rounded-*` classes
+- All 9 pages: spacing upgrades + hardcoded `rounded-*` removals per inventory

+# Phase 5: Design System Token Rework - Research

+**Confidence:** HIGH
+

+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- All elements get 0px border radius — truly sharp corners everywhere
+- Implementation via single `--radius: 0` token change in `src/index.css` (cascades to all shadcn components)
+- No exceptions for avatars, badges, or any element
+- Third-party components (Recharts bars, Sonner toasts) overridden via CSS selectors to force 0 radius
+- Increase chroma on category fill colors to 0.22+ for visible colorful pop against white backgrounds
+- Keep the two-tier color system: text colors at ~0.55L for WCAG 4.5:1 contrast, fill colors lighter/more saturated
+- Slightly warm the base UI colors: background chroma from 0.005→0.01 for subtle warmth
+- Align chart colors with category fill tokens directly — remove separate `--color-chart-*` variables and use `--color-*-fill` tokens in charts
+- Increase section gaps: gap-4→gap-6, gap-6→gap-8 across all pages
+- Increase card internal padding: p-4→p-6 for breathing room
+- Keep existing max-w-7xl container constraint
+- Standardize all page headers to mb-6 + section gaps to gap-8 for consistent rhythm
+
+### Claude's Discretion
+- Exact OKLCH chroma/lightness values for category fills (as long as they're 0.22+ chroma and pass WCAG)
+- Order of page updates during implementation
+- Whether to create a spacing utility class or apply changes inline
+
+### Deferred Ideas (OUT OF SCOPE)
+None — discussion stayed within phase scope

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|------------------|
+| DS-01 | User sees sharp-edged UI across all pages (no rounded corners) | Single `--radius: 0` token in index.css cascades to all shadcn/ui components; hardcoded `rounded-*` Tailwind classes in pages/components require explicit removal; Recharts bars and Sonner toasts require CSS override selectors |
+| DS-02 | User sees clear pastel colors that are visibly colorful, not washed out | Raise `--color-*-fill` chroma from 0.18-0.20 to 0.22+; remove `--color-chart-*` variables; point chart components to `--color-*-fill` tokens directly |
+| DS-03 | User sees a clean, minimal layout with generous whitespace | Upgrade `space-y-6`→`space-y-8`, `gap-6`→`gap-8` across 9 pages; `p-4`→`p-6` for card internals; standardize PageShell gap to `gap-8` |
+</phase_requirements>
+
+---
+
+## Summary
+
+Phase 5 is a pure design token and spacing rework with zero feature additions. The codebase uses Tailwind CSS 4's `@theme inline` block in `src/index.css` as the single source of truth for all CSS custom properties. Because shadcn/ui components reference `--radius` via Tailwind's `rounded-*` utility classes that are generated from this token, setting `--radius: 0` in `src/index.css` propagates automatically to every shadcn component. No changes to `src/components/ui/` files are needed for the radius.
+
+However, hardcoded `rounded-*` Tailwind classes exist in 6 page files and 4 component files — these are not driven by `--radius` and must be removed or changed to `rounded-none` explicitly. Additionally, Recharts bar components pass a `radius` prop (not CSS) and require a CSS selector override in `index.css`. Sonner toasts pass `--border-radius` as an inline style through the Toaster component and additionally need a CSS override.
+
+The color work has two parts: (1) editing token values in `src/index.css` only, and (2) removing `--color-chart-*` variables from `index.css` and updating the two chart components that currently reference them via `ChartConfig` objects to instead reference `--color-*-fill` tokens.
+
+**Primary recommendation:** Execute as three focused waves — (1) token edit in `index.css` (radius + colors + remove chart vars), (2) chart component updates to reference fill tokens, (3) per-page spacing and hardcoded `rounded-*` sweep across all 9 pages.
+
+---
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Design token definition | CSS (index.css) | — | Single `@theme inline` block is the authoritative token source |
+| shadcn component rounding | CSS token cascade | — | `rounded-*` utilities derive from `--radius`; no component code change needed |
+| Hardcoded Tailwind class removal | Page/component TSX | — | `rounded-full`, `rounded-md` etc. are inline JSX; must be changed in source files |
+| Recharts bar radius override | CSS global selector | Recharts prop | CSS `rect` selector overrides SVG radius attribute; prop change is alternative |
+| Sonner toast radius override | CSS global selector | Sonner component | Inline `--border-radius` style in sonner.tsx; CSS override wins |
+| Color token values | CSS (index.css) | — | All category and fill colors live in `@theme inline` |
+| Chart color wiring | Chart TSX components | CSS tokens | `ChartConfig` objects in SpendBarChart and IncomeBarChart must reference fill tokens |
+| Page spacing | Page TSX files | Shared components | `gap-*`, `space-y-*`, `p-*` are inline classes in page JSX |
+

+## Standard Stack
+
+### Core
+
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| Tailwind CSS | 4.2.1 | Utility CSS + token system (`@theme inline`) | Already installed; `@theme inline` is the v4 way to define CSS variables as Tailwind utilities |
+| shadcn/ui | new-york preset | Component layer above Radix UI | Already installed; all components in `src/components/ui/` |
+| Recharts | 2.15.4 | Chart rendering (BarChart, PieChart) | Already installed; SpendBarChart, IncomeBarChart, ExpenseDonutChart use it |
+| Sonner | 2.0.7 | Toast notifications | Already installed; `src/components/ui/sonner.tsx` wraps it |
+
+### Supporting
+
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|

+
+### Pattern 1: Tailwind 4 `@theme inline` Token Edit
+
+**What:** All CSS variables in the `@theme inline` block are automatically available as Tailwind utility classes. Changing a value in this block propagates everywhere the utility is used.
+**When to use:** Changing `--radius`, color tokens, any design-system-level property.
+**Example:**
+```css
+/* src/index.css */
+@theme inline {
+  --radius: 0;  /* was 0.625rem — single change, cascades everywhere */
+
+  /* Fill colors: raise chroma to 0.22+ */
+  --color-income-fill: oklch(0.72 0.22 155);
+  --color-bill-fill: oklch(0.70 0.22 25);
+  --color-variable-expense-fill: oklch(0.74 0.22 50);
+  --color-debt-fill: oklch(0.66 0.23 355);
+  --color-saving-fill: oklch(0.72 0.22 220);
+  --color-investment-fill: oklch(0.68 0.22 285);
+
+  /* Background: warm slightly */
+  --color-background: oklch(0.98 0.01 260);
+
+  /* Remove --color-chart-1 through --color-chart-5 entirely */
+}
+```
+[VERIFIED: codebase — src/index.css lines 1-99]
+
+### Pattern 2: CSS Selector Override for Third-Party Radius
+
+**What:** When a third-party library applies border-radius via its own SVG attributes or inline styles, a targeted CSS selector override in `@layer base` in `index.css` forces the desired value.
+**When to use:** Recharts bar SVG rectangles, Sonner toast container.
+**Example:**
+```css
+/* src/index.css — in @layer base block or after @theme */
+/* Recharts: bars are SVG <rect> elements; CSS border-radius overrides SVG rx/ry */
+.recharts-rectangle {
+  rx: 0;
+  ry: 0;
+}
+
+/* Sonner: targets the toast wrapper element */
+[data-sonner-toast] {
+  border-radius: 0 !important;
+}
+```
+[ASSUMED — selector names from Recharts/Sonner DOM inspection convention; verify in browser devtools during implementation]
+
+### Pattern 3: Hardcoded Tailwind Class Removal
+
+**What:** `rounded-full`, `rounded-md`, `rounded-sm`, `rounded-lg` as inline className strings in TSX are not driven by `--radius`. They must be removed or replaced with `rounded-none`.
+**When to use:** Category color swatches, skeleton shapes, chart legend dots, picker items.
+**Example:**
+```tsx
+/* Before — in ExpenseDonutChart.tsx line 141 */
+<span className="inline-block size-3 shrink-0 rounded-full" ... />
+
+/* After */
+<span className="inline-block size-3 shrink-0" ... />
+/* or explicitly: rounded-none if you need to reset a parent's rounded */
+```
+[VERIFIED: codebase scan]
+
+### Pattern 4: Chart Component Token Wiring
+
+**What:** `SpendBarChart` and `IncomeBarChart` use `ChartConfig` objects to map data keys to colors. Currently `IncomeBarChart.actual` is `color: "var(--color-income-fill)"` — already correct. `SpendBarChart.budgeted` uses `--color-budget-bar-bg` and `actual` uses `--color-muted-foreground`. `Bar radius` props must go to 0.
+**When to use:** Any chart using Recharts `Bar` component.
+**Example:**
+```tsx
+/* IncomeBarChart.tsx — Bar radius change */
+<Bar dataKey="budgeted" fill="var(--color-budgeted)" radius={0} />
+<Bar dataKey="actual" radius={0}>
+
+/* SpendBarChart.tsx — Bar radius change */
+<Bar dataKey="budgeted" fill="var(--color-budgeted)" radius={0} />
+<Bar dataKey="actual" radius={0}>
+```
+Note: `SpendBarChart` uses `Cell` with dynamic `var(--color-${entry.type}-fill)` — this already references fill tokens, which is correct post-rework. No ChartConfig color change needed there.
+[VERIFIED: codebase — SpendBarChart.tsx, IncomeBarChart.tsx]
+
+### Pattern 5: Spacing Upgrade Pattern
+
+**What:** Page-level spacing classes that control section separation and card internal rhythm are upgraded in-place in each page's JSX.
+**When to use:** Each of the 9 pages.
+**Mapping:**
+```
+space-y-6  → space-y-8   (section-level vertical rhythm in pages)
+gap-6      → gap-8       (grid gaps between card sections)
+gap-4      → gap-6       (inner grid element gaps where currently gap-4)
+```
+Card internal padding (`p-4` → `p-6`) applies to card content divs in pages, not to `src/components/ui/card.tsx` directly (Card already uses `py-6` and `CardContent` uses `px-6`).
+[VERIFIED: codebase — PageShell.tsx, DashboardPage.tsx, BudgetDetailPage.tsx]
+
+### Anti-Patterns to Avoid
+
+- **Editing shadcn component files for radius:** `src/components/ui/*.tsx` do NOT need edits for the radius change — the token cascade handles it. Editing them directly risks breaking shadcn's upgrade path.
+- **Changing `src/components/ui/card.tsx` padding:** `CardContent` already uses `px-6`. The `p-4 → p-6` upgrade applies to page-level wrappers that add inner padding on top of card defaults, not to the Card component itself.
+- **Adding new `rounded-none` classes broadly:** Prefer removing the hardcoded `rounded-*` class entirely over adding `rounded-none`, since `--radius: 0` already means all `rounded-md`/`rounded-sm` Tailwind classes resolve to 0px. Only add `rounded-none` if you need to explicitly reset a parent that might not be covered.
+- **Relying on `--color-chart-*` variables in new code:** These are being deleted this phase. All chart coloring must reference `--color-*-fill` tokens going forward.

+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| WCAG contrast calculation | Manual contrast ratio math | Use UI-SPEC.md confirmed values; verify with browser devtools color picker | OKLCH values already computed and confirmed in CONTEXT.md and UI-SPEC.md |
+| CSS-in-JS color token system | Runtime token object | Tailwind 4 `@theme inline` already does this | Single file, zero runtime cost |
+| Per-component radius reset | Adding `style={{ borderRadius: 0 }}` to every element | `--radius: 0` token | Token cascade handles all shadcn components in one edit |
+| Custom chart color mapping | Separate color registry | Existing `var(--color-*-fill)` CSS variables | Already wired in ExpenseDonutChart; standardize SpendBarChart/IncomeBarChart to match |

+
+### Components
+
+| File | Line | Class | Action |
+|------|------|-------|--------|
+| CategorySection.tsx | 73 | `rounded-md` (collapsible trigger button) | Remove |
+| DashboardSkeleton.tsx | 35,43,51 | `rounded-md` (Skeleton placeholders) | Remove |
+| DashboardSkeleton.tsx | 59 | `rounded-md` (row placeholder) | Remove |
+| DashboardSkeleton.tsx | 63,64 | `rounded-full` (Skeleton) | Remove |
+| ChartEmptyState.tsx | 12 | `rounded-lg` (empty state border) | Remove |
+| ExpenseDonutChart.tsx | 141 | `rounded-full` (legend color dot) | Remove |
+| QuickAddPicker.tsx | 156 | `rounded-sm` (picker item) | Remove |
+| QuickAddPicker.tsx | 201 | `rounded-full` (category dot) | Remove |
+
+**Note on Skeleton components:** `Skeleton` in `src/components/ui/skeleton.tsx` has `rounded-md` in its base class (`animate-pulse rounded-md bg-accent`). When `--radius: 0`, `rounded-md` resolves to 0px automatically — skeleton rounding is already handled by the token. The hardcoded `rounded-full` overrides on individual `<Skeleton>` usages (which pass `className` that overrides the base) must still be removed to avoid pill-shaped skeletons.
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: Skeleton `rounded-full` Overrides Persist
+
+**What goes wrong:** After `--radius: 0`, the base `Skeleton` component becomes square. But in multiple pages, Skeleton elements are given `className="h-5 w-16 rounded-full"`. Since `rounded-full` uses a fixed `border-radius: 9999px` that does not derive from `--radius`, those skeleton placeholders remain pill-shaped.
+**Why it happens:** `rounded-full` in Tailwind is always `9999px` regardless of the `--radius` token. Only `rounded-md`, `rounded-sm`, `rounded-lg`, `rounded-xl` etc. derive from `--radius`.
+**How to avoid:** Remove `rounded-full` from every `className` passed to `<Skeleton>` as listed in the inventory above.
+**Warning signs:** Pill-shaped loading placeholders visible on BudgetDetail, Template, Categories, QuickAdd pages after the token change.
+
+### Pitfall 2: Recharts `radius` Prop vs. CSS
+
+**What goes wrong:** `<Bar radius={4}>` and `<Bar radius={[4, 4, 0, 0]}>` are SVG attribute props, not CSS. Setting `--radius: 0` does not affect them. CSS overrides on `.recharts-rectangle` may also need `rx: 0; ry: 0` as SVG presentation attributes.
+**Why it happens:** Recharts renders bars as `<rect rx="4" ry="4">` SVG elements. CSS `border-radius` on SVG `rect` has browser-level quirks — some browsers respect it, others require the `rx`/`ry` attributes.
+**How to avoid:** Change the `radius` prop to `0` directly on `<Bar>` in both `SpendBarChart.tsx` and `IncomeBarChart.tsx`. This is the most reliable fix.
+**Warning signs:** Chart bars still have rounded caps after CSS override but not prop change.
+
+### Pitfall 3: Sonner Toast Radius Override Specificity
+
+**What goes wrong:** Sonner's Toaster component passes `"--border-radius": "var(--radius)"` as an inline `style` prop. After setting `--radius: 0`, this should automatically propagate. However, Sonner also has its own internal styles.
+**Why it happens:** The sonner.tsx wrapper already wires `--border-radius` to `var(--radius)`. When `--radius` becomes `0`, this should cascade automatically. The risk is Sonner's own stylesheet having higher specificity.
+**How to avoid:** Verify in browser after `--radius: 0` change. If toasts are still rounded, add `[data-sonner-toast] { border-radius: 0 !important; }` to `index.css`.
+**Warning signs:** Toast notifications still display with rounded corners after `--radius: 0` edit.
+
+### Pitfall 4: `--color-chart-*` Still Referenced After Deletion
+
+**What goes wrong:** After removing `--color-chart-1` through `--color-chart-5` from `index.css`, if any component still references them the color falls back to transparent/browser default (usually black or undefined).
+**Why it happens:** The variables are only defined in one place but could theoretically be referenced in multiple chart config objects.
+**How to avoid:** Before deleting, grep the entire `src/` directory for `color-chart` to confirm only `index.css` references them (already confirmed — zero TSX references found). Safe to delete.
+**Warning signs:** Charts render with black or missing colors.
+
+### Pitfall 5: `PageShell` `gap-6` Governs All Page Layouts
+
+**What goes wrong:** `PageShell` uses `flex flex-col gap-6`. Because it wraps most pages, the gap between the page header and first content section is controlled here. Updating spacing in individual pages but not in `PageShell` creates inconsistency.
+**Why it happens:** PageShell is a shared wrapper — spacing changes to individual pages don't affect header-to-content gap unless PageShell is also updated.
+**How to avoid:** Update `PageShell` from `gap-6` to `gap-8` as part of the spacing wave. All pages using `PageShell` benefit automatically.
+**Warning signs:** Pages with `PageShell` wrapper still show tight header-to-content gap despite page-level spacing upgrades.
+
+### Pitfall 6: Donut Chart Legend Dots Remain Circular
+
+**What goes wrong:** The custom legend in `ExpenseDonutChart.tsx` uses `<span className="inline-block size-3 shrink-0 rounded-full">` for category color dots. These remain pill/circle shaped because `rounded-full` is hardcoded.
+**Why it happens:** The legend is custom HTML, not a Recharts component — token cascade doesn't reach it.
+**How to avoid:** Remove `rounded-full` from the legend span. A square dot of 3×3px is intentionally square in the sharp design aesthetic.
+**Warning signs:** Circular color swatches in the donut chart legend after the rework.

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Separate `--color-chart-*` variables | Reference `--color-*-fill` directly | This phase | Eliminates color duplication; single source of truth per category |
+| `--radius: 0.625rem` | `--radius: 0` | This phase | All shadcn components become sharp-cornered |
+| Fill chroma 0.18-0.20 | Fill chroma 0.22+ | This phase | Visually saturated pastels that read as colorful, not grey |
+| `gap-6` / `space-y-6` sections | `gap-8` / `space-y-8` | This phase | More generous breathing room between content sections |
+
+---
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | Sonner toast `--border-radius: var(--radius)` inline style in sonner.tsx will propagate `--radius: 0` correctly without additional CSS override | Pitfall 3 / Pattern 2 | If wrong, toasts remain rounded; mitigation: add `[data-sonner-toast] { border-radius: 0 !important }` as CSS override |
+| A2 | CSS `rx: 0; ry: 0` on `.recharts-rectangle` overrides SVG presentation attributes cross-browser | Pitfall 2 | If wrong, bars may still show rounding in some browsers; mitigation: change `radius` prop to 0 on `<Bar>` (reliable) |
+| A3 | No `--color-chart-*` references exist in any TSX file (confirmed by grep returning zero results) | Don't Hand-Roll | LOW risk — grep confirmed no TSX references |
+
+---
+
+## Open Questions
+
+1. **Sonner version 2.x selector name for border-radius override**
+   - What we know: Sonner 2.0.7 is installed; `[data-sonner-toast]` is the conventional selector from v1/v2
+   - What's unclear: Whether v2.x changed the data attribute name on the toast wrapper
+   - Recommendation: Verify in browser devtools after `--radius: 0` change; if toasts remain rounded, inspect the DOM element for the correct attribute selector
+
+2. **`space-y-6` vs `gap-6` on TemplatePage and BudgetDetailPage**
+   - What we know: These pages use `space-y-6` for section stacking (not `gap-*` which requires flex/grid parent)
+   - What's unclear: Whether changing `space-y-6` → `space-y-8` alone is sufficient or whether the wrapping flex container also needs `gap-8`
+   - Recommendation: Apply `space-y-8` where currently `space-y-6`; apply `gap-8` where currently `gap-6` in flex/grid containers — both changes are needed depending on context

+
+## Environment Availability
+
+Step 2.6: SKIPPED — Phase 5 is purely CSS/TSX file edits with no external dependencies, database changes, or CLI tools beyond the existing Vite dev server.
+
+---
+
+## Validation Architecture
+
+### Test Framework
+
+| Property | Value |
+|----------|-------|
+| Framework | None detected — no jest.config.*, vitest.config.*, pytest.ini found |
+| Config file | None — Wave 0 gap |
+| Quick run command | `npm run build` (TypeScript compile check) |
+| Full suite command | Manual visual pass across 9 pages in browser |
+
+### Phase Requirements → Test Map
+
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| DS-01 | No rounded corners visible anywhere | Manual (visual) | `npm run build` (compile check only) | N/A — visual |
+| DS-02 | Category fills visibly colorful, not washed out | Manual (visual) | `npm run build` | N/A — visual |
+| DS-03 | Generous whitespace, no visual crowding | Manual (visual) | `npm run build` | N/A — visual |
+
+### Sampling Rate
+
+- **Per task commit:** `npm run build` — confirms no TypeScript errors
+- **Per wave merge:** `npm run build` + manual browser check of affected pages
+- **Phase gate:** Full 9-page visual pass per the UI-SPEC checklist before `/gsd-verify-work`
+
+### Wave 0 Gaps
+
+- [ ] No unit/integration test infrastructure exists — this phase is purely visual; manual browser verification is the acceptance gate
+- [ ] Consider running `npm run lint` as a secondary automated check
+
+---
+
+## Security Domain
+
+Security enforcement: not applicable. Phase 5 introduces zero new features, endpoints, authentication flows, user input handling, or data access. No ASVS categories apply. This is a pure CSS token and spacing change.
+
+---
+
+## Sources
+
+### Primary (HIGH confidence)
+- `src/index.css` (codebase) — Full token inventory, current `--radius` value, all OKLCH color values, `--color-chart-*` variables
+- `src/components/ui/` (codebase) — shadcn component source confirming `rounded-*` class usage, `sonner.tsx` Toaster inline style wiring
+- `src/components/dashboard/charts/` (codebase) — Recharts `Bar` radius prop values, ChartConfig objects, Cell fill patterns
+- `src/pages/` (codebase) — All 9 pages audited for `gap-*`, `space-y-*`, `rounded-*` classes
+- `05-UI-SPEC.md` (project planning) — Confirmed post-rework color values, spacing targets, component inventory
+
+### Secondary (MEDIUM confidence)
+- Tailwind CSS 4 `@theme inline` documentation — `rounded-md` etc. derive from `--radius` token; `rounded-full` does not
+
+### Tertiary (LOW confidence — A1, A2 in assumptions log)
+- Sonner 2.x data attribute selector name (`[data-sonner-toast]`) — based on conventional usage; verify in browser
+- Recharts CSS `rx`/`ry` override cross-browser behavior — recommend prop change as primary approach
+
+---
+
+## Metadata
+
+**Confidence breakdown:**
+- Token edit scope (index.css): HIGH — full file read, all variables inventoried
+- Hardcoded rounded-* inventory: HIGH — exhaustive grep of src/pages + src/components
+- Spacing upgrade targets: HIGH — grep confirmed current class values in all 9 pages
+- Third-party overrides (Recharts, Sonner): MEDIUM — prop-based fix is reliable; CSS override selector needs browser verification
+- Color OKLCH values: HIGH — values provided in CONTEXT.md and UI-SPEC.md

+# Phase 5 — UI Design Contract
+
+> Visual and interaction contract for Phase 5: Design System Token Rework.
+> Generated by gsd-ui-researcher, verified by gsd-ui-checker.
+>
+> This phase is a pure token and spacing rework — no new components, no new features.
+> Every entry in this contract describes what must be TRUE after the change, not before.

+
+## Design System
+
+| Property | Value | Source |
+|----------|-------|--------|
+| Tool | shadcn/ui | components.json |
+| Style | new-york | components.json |
+| Preset | neutral base, cssVariables: true | components.json |
+| Component library | Radix UI (via shadcn) | components.json |
+| Icon library | lucide-react | components.json |
+| Font | Inter (--font-sans) | src/index.css |
+
+---
+
+## Spacing Scale
+
+Declared values (all multiples of 4):
+
+| Token | px Value | Tailwind Class | Usage |
+|-------|----------|----------------|-------|
+| xs | 4px | gap-1 / p-1 | Icon gaps, inline tight spacing |
+| sm | 8px | gap-2 / p-2 | Compact inline elements, badge padding |
+| md | 16px | gap-4 / p-4 | Default inline element spacing |
+| lg | 24px | gap-6 / p-6 | Card internal padding (upgraded from p-4) |
+| xl | 32px | gap-8 | Section gaps between cards and sections (upgraded from gap-6) |
+| 2xl | 48px | gap-12 | Major section breaks, page-level vertical rhythm |
+| 3xl | 64px | py-16 | Auth page vertical centering, hero areas |
+
+**Phase 5 spacing changes (from CONTEXT.md):**
+- Card internal padding: `p-4` → `p-6` across all 9 pages
+- Section gaps: `gap-4` → `gap-6`, `gap-6` → `gap-8` across all pages
+- Page header bottom margin: standardize to `mb-6` everywhere
+- Section-to-section gap: standardize to `gap-8`
+
+Exceptions: none — 8-point scale applies without exception.
+
+---
+
+## Typography
+
+| Role | Size | Tailwind | Weight | Weight Class | Line Height | Usage |
+|------|------|----------|--------|--------------|-------------|-------|
+| Caption | 12px | text-xs | 400 | font-normal | 1.5 | Subtitles, secondary metadata |
+| Body / Label | 14px | text-sm | 500 | font-medium | 1.5 | Table cells, form labels, card labels, stat subtitles |
+| Base | 16px | text-base | 500 | font-medium | 1.5 | Card titles (e.g. chart section headings) |
+| Heading | 24px | text-2xl | 600 | font-semibold | 1.2 | Page titles (PageShell h1), auth card titles, template names |
+
+Source: Existing usage in PageShell, StatCard, DashboardPage, LoginPage, RegisterPage confirmed these four sizes as the complete in-use set.
+
+Weights used: exactly 2 — `font-medium` (500) for body/data, `font-semibold` (600) for headings. The rare `font-bold` (700) occurrences in StatCard value display are reclassified as `font-semibold` for consistency.
+
+---
+
+## Color
+
+### Base UI Tokens (post-rework values)
+
+| Role | OKLCH Value | Usage |
+|------|-------------|-------|
+| Background (dominant, 60%) | oklch(0.98 0.01 260) | Page background — chroma lifted 0.005→0.01 for subtle warmth |
+| Card / Popover (secondary, 30%) | oklch(1 0 0) | Cards, modals, popovers, sidebar surface |
+| Sidebar | oklch(0.97 0.008 260) | Sidebar background — no change |
+| Primary accent (10%) | oklch(0.55 0.15 260) | Active nav items, primary buttons, focus rings |
+| Secondary / Muted | oklch(0.93 0.02 260) | Secondary buttons, muted chip backgrounds |
+| Border / Input | oklch(0.88 0.01 260) | All borders and input outlines |
+| Destructive | oklch(0.6 0.2 25) | Delete actions, error alerts only |
+
+Accent reserved for: primary action buttons, active sidebar navigation item, focus ring outlines, primary CTA buttons. No other elements may use the primary OKLCH(0.55 0.15 260) value.
+
+### Category Text Colors (WCAG 4.5:1 contrast on white — no change to lightness/chroma)
+
+| Token | OKLCH Value | Hue |
+|-------|-------------|-----|
+| --color-income | oklch(0.55 0.17 155) | Green |
+| --color-bill | oklch(0.55 0.17 25) | Orange-red |
+| --color-variable-expense | oklch(0.58 0.16 50) | Amber |
+| --color-debt | oklch(0.52 0.18 355) | Red |
+| --color-saving | oklch(0.55 0.16 220) | Blue |
+| --color-investment | oklch(0.55 0.16 285) | Violet |
+
+### Category Fill Colors (post-rework — chroma raised to 0.22+)
+
+These replace the current fill tokens (C=0.18-0.20). Exact values are at Claude's discretion per CONTEXT.md as long as chroma >= 0.22 and the fills remain visually distinct from each other.
+
+| Token | Target OKLCH | Constraint |
+|-------|--------------|------------|
+| --color-income-fill | oklch(0.72 0.22 155) | C >= 0.22, L ~0.70-0.75 |
+| --color-bill-fill | oklch(0.70 0.22 25) | C >= 0.22, L ~0.68-0.73 |
+| --color-variable-expense-fill | oklch(0.74 0.22 50) | C >= 0.22, L ~0.70-0.76 |
+| --color-debt-fill | oklch(0.66 0.23 355) | C >= 0.22, L ~0.64-0.70 |
+| --color-saving-fill | oklch(0.72 0.22 220) | C >= 0.22, L ~0.70-0.75 |
+| --color-investment-fill | oklch(0.68 0.22 285) | C >= 0.22, L ~0.65-0.72 |
+
+### Chart Colors (post-rework — aligned to fill tokens)
+
+The `--color-chart-1` through `--color-chart-5` variables are REMOVED. Chart components reference `--color-*-fill` tokens directly. This eliminates the duplicate color system.
+
+| Removed | Replaced by |
+|---------|-------------|
+| --color-chart-1 | --color-income-fill |
+| --color-chart-2 | --color-bill-fill |
+| --color-chart-3 | --color-variable-expense-fill |
+| --color-chart-4 | --color-debt-fill |
+| --color-chart-5 | --color-saving-fill |
+
+### Corner Radius
+
+| Token | Current Value | Post-Rework Value | Effect |
+|-------|--------------|-------------------|--------|
+| --radius | 0.625rem (10px) | 0rem (0px) | All shadcn components become sharp-cornered |
+
+Third-party overrides required (applied via CSS selectors in src/index.css):
+- Recharts bar elements: force `rx="0" ry="0"` or CSS `border-radius: 0`
+- Sonner toast container: override `.sonner-toast` border-radius to 0
+
+---
+
+## Copywriting Contract
+
+Phase 5 is a pure visual rework — no new user-facing copy is introduced. The following existing copy elements remain unchanged and are documented here as the confirmed contract.
+
+| Element | Copy | Notes |
+|---------|------|-------|
+| Primary CTA (Budget List) | "New Budget" | Existing — unchanged |
+| Primary CTA (Template) | "Add item" | Existing — unchanged |
+| Primary CTA (Categories) | "New Category" | Existing — unchanged |
+| Empty state (Dashboard) | Translation key: `dashboard.noBudgetForMonth` | Existing — no copy changes this phase |
+| Error state (auth forms) | Translation key: `auth.error` + specific message | Existing — no copy changes this phase |
+| Destructive actions | None introduced in this phase | Token rework only |
+
+No new destructive actions are introduced. No new confirmation dialogs. No new empty states.
+
+---
+
+## Component Inventory
+
+Components affected by token changes (no code changes required — token cascade handles it):
+
+| Component | Location | Rounding Source | Change Required |
+|-----------|----------|-----------------|-----------------|
+| Button | src/components/ui/button.tsx | --radius token | Automatic via --radius: 0 |
+| Card | src/components/ui/card.tsx | --radius token | Automatic; padding class updated to p-6 |
+| Input | src/components/ui/input.tsx | --radius token | Automatic via --radius: 0 |
+| Badge | src/components/ui/badge.tsx | --radius token | Automatic via --radius: 0 |
+| Select | src/components/ui/select.tsx | --radius token | Automatic via --radius: 0 |
+| Sheet | src/components/ui/sheet.tsx | --radius token | Automatic via --radius: 0 |
+| Dialog | src/components/ui/dialog.tsx | --radius token | Automatic via --radius: 0 |
+| Popover | src/components/ui/popover.tsx | --radius token | Automatic via --radius: 0 |
+| Sidebar | src/components/ui/sidebar.tsx | --radius token | Automatic via --radius: 0 |
+| Dropdown Menu | src/components/ui/dropdown-menu.tsx | --radius token | Automatic via --radius: 0 |
+| Recharts bars | SpendBarChart, IncomeBarChart | SVG rx/ry attrs | Explicit CSS override needed |
+| Sonner toasts | src/components/ui/sonner.tsx | Sonner inline styles | CSS selector override needed |
+| Category swatches | CategoriesPage, CategorySection | Hardcoded rounded-* | Audit and remove rounded-* classes |
+| Budget progress bars | BudgetDetailPage | Hardcoded rounded-* | Audit and remove rounded-* classes |
+
+Pages to audit for inline `rounded-*` classes (must be zero after this phase):
+1. DashboardPage — CategorySection swatches, StatCard
+2. BudgetListPage — budget item rows
+3. BudgetDetailPage — progress bars, budget row items
+4. TemplatePage — template item rows, category group headers
+5. CategoriesPage — category color swatches
+6. QuickAddPage — picker items
+7. SettingsPage — form elements
+8. LoginPage — auth card
+9. RegisterPage — auth card

+## Registry Safety
+
+| Registry | Blocks Used | Safety Gate |
+|----------|-------------|-------------|
+| shadcn official (new-york) | button, card, badge, input, label, select, sheet, dialog, popover, sidebar, dropdown-menu, separator, skeleton, table, tooltip, sonner, chart, collapsible | not required |
+| Third-party | none | not applicable |
+
+No third-party registries. No vetting gate required.
+
+---
+
+## Interaction Contract
+
+Phase 5 introduces no new interaction patterns. Existing interactions are preserved. The following are confirmed unchanged:
+
+- Collapsible sections: 200ms ease-out open/close animation (--animate-collapsible-open/close) — no change
+- Sidebar navigation: active state uses primary color — no change to behavior
+- Form validation: error states use `--color-destructive` — no change
+- Chart tooltips: Recharts default — style override via chart.tsx config only
+
+---
+
+## Visual Regression Checklist
+
+The executor must perform a manual visual pass after all token changes confirming:
+
+- [ ] No pill buttons visible on any of the 9 pages
+- [ ] No rounded cards visible on any of the 9 pages
+- [ ] No rounded inputs visible on any of the 9 pages
+- [ ] Category fill colors are visibly colorful against white (not grey-tinted)

+- [ ] Page headers have consistent bottom margin before first content section
+- [ ] Recharts bars are square-ended (no rounded caps)
+- [ ] Sonner toasts have sharp corners
+
+---

+
+## Goal Achievement
+
+### Observable Truths (Roadmap Success Criteria)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|---------|
+| SC-1 | Every rounded element across all 9 pages has sharp corners — no pill buttons, no rounded cards, no rounded inputs | PARTIAL | Hardcoded rounded-* removed from all pages/shared components (CONFIRMED), but shadcn primitives (Card/Button/Input) use Tailwind v4 named radius utilities that resolve to non-zero values in built CSS (--radius-md=.375rem, --radius-xl=.75rem) |
+| SC-2 | Category color swatches visibly colorful against white, still pass WCAG 4.5:1 | ? NEEDS HUMAN | All 6 fill vars raised to chroma 0.22-0.23 (CONFIRMED in index.css), WCAG text contrast vars separate and unchanged; visual confirmation needed |
+| SC-3 | Page layouts feel uncluttered — consistent whitespace gaps, no visual crowding | ? NEEDS HUMAN | gap-8/space-y-8 implemented across all pages (CONFIRMED); subjective design judgment requires human |
+| SC-4 | Full visual pass of all 9 pages confirms no regressions from token changes | ? NEEDS HUMAN | Build passes (CONFIRMED); visual pass cannot be automated |
+
+**Verified:** 0/4 roadmap SCs fully verified (3 need human, 1 has a code gap)
+
+### Plan Must-Haves (All Plans Combined)
+
+| # | Must-Have | Status | Evidence |
+|---|-----------|--------|---------|
+| 1 | `--radius: 0` in index.css, cascading sharp corners to all shadcn components | PARTIAL | `--radius: 0` confirmed in index.css; cascade does NOT reach shadcn primitives via Tailwind v4's named radius utilities |
+| 2 | Category fill chromas >= 0.22 | VERIFIED | income: 0.22, bill: 0.22, variable-expense: 0.22, debt: 0.23, saving: 0.22, investment: 0.22 |
+| 3 | `--color-chart-*` variables deleted from index.css | VERIFIED | Zero matches for `color-chart-[1-5]` in entire src/ directory |
+| 4 | Chart bars render with radius={0} (no rounded caps) | VERIFIED | SpendBarChart: 2x radius={0}; IncomeBarChart: 2x radius={0} |
+| 5 | CSS overrides for Recharts rectangles and Sonner toasts | VERIFIED | `.recharts-rectangle { rx: 0; ry: 0 }` and `[data-sonner-toast] { border-radius: 0 !important }` in index.css |
+| 6 | PageShell gap is gap-8 | VERIFIED | Line 15 of PageShell.tsx: `"flex flex-col gap-8"` |
+| 7 | All shared component hardcoded rounded-* removed | VERIFIED | DashboardSkeleton, CategorySection, ChartEmptyState, QuickAddPicker all clean |
+| 8 | All 9 pages have no hardcoded rounded-* classes remaining | VERIFIED | grep -rn on src/pages/ returns NO matches |
+
+**Plan score:** 7/8 must-haves fully verified (1 partial on cascading)

+## Requirements Coverage
+
+| Requirement | Plans | Description | Status | Evidence |
+|-------------|-------|-------------|--------|---------|
+| DS-01 | 05-01, 05-02, 05-03 | User sees sharp-edged UI across all pages (no rounded corners) | PARTIAL | Hardcoded rounded-* removed from all pages and app-layer components; shadcn primitives still use Tailwind v4 named radius utilities that resolve to non-zero values |
+| DS-02 | 05-01, 05-03 | User sees clear pastel colors that are visibly colorful, not washed out | NEEDS HUMAN | Fill chroma values raised to 0.22-0.23 (code confirmed); visual perception of color vividness requires human confirmation |
+| DS-03 | 05-02, 05-03 | User sees clean, minimal layout with generous whitespace | NEEDS HUMAN | gap-8/space-y-8 spacing values confirmed in all pages; whether this reads as "generous whitespace" requires human design judgment |
+
+---
+
+## Anti-Patterns Found
+
+| File | Pattern | Severity | Impact |
+|------|---------|----------|--------|
+| `src/index.css` | `--radius: 0` assumed to cascade to Tailwind v4 named radius utilities, but built CSS proves --radius-md=.375rem | BLOCKER | shadcn Cards, Buttons, Inputs remain rounded despite the token change |
+| `05-RESEARCH.md` | Research document incorrectly states "rounded-* utilities derive from --radius" in Tailwind v4 | INFO | Root cause of the gap; no direct code impact, but planning assumption was wrong |
+
+---
+
+## Human Verification Required
+
+### 1. Sharp Corners on Shadcn Primitives
+
+**Test:** Open the app (`bun run dev`), then inspect Cards (on Dashboard, Budget List, Login), Buttons (all pages), and Inputs (Settings, Login, Register) using browser DevTools (Computed styles → border-radius).
+**Expected:** border-radius = 0px on all elements
+**Why human:** Browser DevTools can confirm the actual computed border-radius. The code gap analysis predicts non-zero radius on shadcn primitives (Card=0.75rem, Button/Input=0.375rem), but runtime behavior must be confirmed visually and via DevTools to be certain.
+
+### 2. Category Color Vividness (DS-02)
+
+**Test:** Open the Categories page and the Dashboard category sections. Compare category color swatches against the white page background.
+**Expected:** Swatches are clearly, distinctly colorful — income green is vivid, bill orange/red is vivid, etc. None appear grey-tinted or washed out.
+**Why human:** Color vividness (chroma 0.22-0.23 OKLCH) is a perceptual judgment. The token values are confirmed correct but whether they achieve "clearly pastel" vs "washed out" requires human perception.
+
+### 3. Bar Chart Square Ends (DS-01 partial)
+
+**Test:** Open the Dashboard and observe the SpendBarChart and IncomeBarChart. Look at the tops of the bars.
+**Expected:** Bar tops terminate in 90-degree corners — no visible rounded caps. The `.recharts-rectangle` CSS override and `radius={0}` prop are both in place.
+**Why human:** Recharts SVG rendering of the CSS `rx`/`ry` override needs visual confirmation in a browser.
+
+### 4. Whitespace and Layout Rhythm (DS-03)
+
+**Test:** Navigate through all 9 pages — Dashboard, Budget List, Budget Detail, Template, Categories, Quick Add, Settings, Login, Register.
+**Expected:** Section gaps feel spacious and uncluttered. Content is readable without feeling cramped. Page headers have consistent spacing before first content section.
+**Why human:** Whether gap-8 and space-y-8 achieve "generous whitespace" and a "clean, minimal layout" is a design judgment that cannot be verified programmatically.
+
+---
+
+## Gaps Summary
+
+**1 code gap blocking full goal achievement:**
+
+The `--radius: 0` token in `src/index.css` was correctly set, and the research/plan correctly identified that this should cascade to all shadcn UI components. However, Tailwind v4's named radius utility scale (`--radius-md`, `--radius-xl`, etc.) is an **independent scale** that is NOT derived from `--radius`. The built CSS confirms `--radius-md: .375rem` and `--radius-xl: .75rem` remain at their Tailwind defaults.
+
+All shadcn primitive components use these named utilities:
+- `Card` → `rounded-xl` → `var(--radius-xl)` = **0.75rem** (not sharp)
+- `Button` → `rounded-md` → `var(--radius-md)` = **0.375rem** (not sharp)
+- `Input` → `rounded-md` → `var(--radius-md)` = **0.375rem** (not sharp)
+- `Badge` → `rounded-full` → **3.4e38px** (pill-shaped — not sharp)
+- `Select` → `rounded-md` → **0.375rem** (not sharp)
+- `Dialog`/`Sheet`/`Popover` → `rounded-md`/`rounded-lg` → non-zero (not sharp)
+
+The fix is a one-line addition to the `@theme inline` block in `src/index.css` — explicitly set all radius scale variables to 0 alongside `--radius: 0`.
+
+All other must-haves are fully verified. The spacing upgrades, fill color chromas, chart var removal, chart Bar radius, Recharts/Sonner CSS overrides, and hardcoded rounded-* removal from all pages and shared components are all correctly implemented and confirmed in the actual codebase.

+
+<objective>
+Write two Supabase migration files and update the Profile TypeScript type.
+
+Migration 006 makes duplicate budget/category creation impossible at the DB level by first deduplicating any existing rows then adding UNIQUE constraints. Migration 007 adds the `setup_completed` boolean column to `profiles` and backfills existing users who have categories to `true`. The TypeScript `Profile` interface in `src/lib/types.ts` is updated to include `setup_completed: boolean`.
+
+Purpose: The DB layer must enforce uniqueness atomically (prevents race conditions) and must know which users have already completed setup (prevents existing v1.0 users from seeing the wizard on first v2.0 login).
+Output: 2 `.sql` migration files + 1 updated TypeScript type file.

+# Phase 06 Plan 01: DB Safety Constraints and First-Run Flag Summary
+
+**One-liner:** Two atomic SQL migrations adding UNIQUE constraints on budgets/categories with safe deduplication, plus a `setup_completed` boolean on profiles with UNION backfill, synced to the TypeScript Profile interface.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |

+| 1 | Migration 006: uniqueness constraints | 23fd3fa | supabase/migrations/006_uniqueness_constraints.sql |

+| 3 | Update Profile TypeScript interface | 39840ca | src/lib/types.ts |
+
+## What Was Built
+
+**Migration 006** (`006_uniqueness_constraints.sql`): A single `BEGIN/COMMIT` transaction that:
+1. DELETEs duplicate budgets keeping the oldest per `(user_id, start_date)` using `DISTINCT ON`
+2. ADDs `CONSTRAINT budgets_user_month_unique UNIQUE (user_id, start_date)`
+3. DELETEs duplicate categories keeping the oldest per `(user_id, name)` using `DISTINCT ON`
+4. ADDs `CONSTRAINT categories_user_name_unique UNIQUE (user_id, name)`
+
+**Migration 007** (`007_setup_completed.sql`): Two statements:
+1. `ALTER TABLE profiles ADD COLUMN setup_completed boolean NOT NULL DEFAULT false`
+2. `UPDATE profiles SET setup_completed = true WHERE id IN (SELECT DISTINCT user_id FROM categories UNION SELECT t.user_id FROM templates t INNER JOIN template_items ti ON ti.template_id = t.id)`
+
+**TypeScript** (`src/lib/types.ts`): Added `setup_completed: boolean` to the `Profile` interface between `currency` and `created_at`. `tsc --noEmit` passes cleanly.
+
+## Deviations from Plan
+
+None — plan executed exactly as written. The UNION backfill in migration 007 was specified in the plan (per Pitfall 3 guidance from RESEARCH.md).
+
+## Known Stubs
+
+None — this plan produces SQL DDL and a TypeScript type update; no UI or data-flow stubs.
+
+## Threat Flags
+
+No new threat surface beyond what was documented in the plan's threat model. The UNIQUE constraints directly address T-06-01 and T-06-02. The `setup_completed` column is a UX routing flag with existing RLS (T-06-03 accepted).

+<objective>
+Create the static preset budget item library and its i18n translations.
+
+`src/data/presets.ts` exports `PresetItem` interface and `PRESETS` array with 19 items across 6 category types (4 income, 4 bill, 5 variable_expense, 2 debt, 2 saving, 2 investment). Both `src/i18n/en.json` and `src/i18n/de.json` get a new top-level `"presets"` key containing all 19 English/German display names.
+
+Purpose: This is the curated item library the Phase 7 wizard shows to new users for one-click budget template setup. All amounts are plain EUR numbers — the wizard reads currency from `profiles.currency`, not from this file.
+Output: `src/data/presets.ts`, updated `en.json`, updated `de.json`.

+
+Static 19-item preset budget library with English and German translations, structured as `presets.{type}.{slug}` i18n keys matching the PRESETS array shape.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Create src/data/presets.ts | 3bc7782 | src/data/presets.ts (created) |

+## What Was Built
+
+`src/data/presets.ts` exports `PresetItem` interface and `PRESETS` array with exactly 19 items:
+- 4 income, 4 bill, 5 variable_expense, 2 debt, 2 saving, 2 investment
+- All `item_tier` values are `"fixed"` or `"variable"` (no `"one_off"`)
+- Pure static module — no Supabase or React imports
+
+Both i18n files now have a top-level `"presets"` key with nested `{type}.{slug}` structure covering all 19 slugs in English and German.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.

+---
+
+<objective>
+Write the `useFirstRunState` hook and push all migrations to the database.
+
+`useFirstRunState` derives first-run state from existing React Query caches — no extra network call. It returns `{ isFirstRun: boolean, loading: boolean }` where `isFirstRun` is `true` when either categories or template items count is zero, and `loading` is `true` while either underlying query is still fetching.
+
+The DB schema push applies migrations 006 and 007, making uniqueness constraints and the `setup_completed` column live. This is a `[BLOCKING]` step — all verification depends on the schema being applied.
+
+Purpose: Phase 7 wizard reads `useFirstRunState().isFirstRun` to decide whether to redirect new users to setup. The DB constraints prevent the data corruption that would require rollback work in Phase 8.
+Output: `src/hooks/useFirstRunState.ts` + DB schema pushed + human verification checkpoint.

+# Phase 06 Plan 03: useFirstRunState Hook and DB Schema Push Summary
+
+Derived first-run detection hook reading from React Query cache with loading guard to prevent spurious redirects, plus live DB schema with uniqueness constraints and setup_completed column.
+
+## What Was Built
+
+### useFirstRunState Hook (src/hooks/useFirstRunState.ts)
+
+A read-only derived state hook that composes `useCategories()` and `useTemplate()` to determine whether the current user is a first-run user (no categories or no template items). Returns `{ isFirstRun: boolean, loading: boolean }`. The `loading` flag is critical -- callers in Phase 7 must check `!loading && isFirstRun` before redirecting to prevent false positives while queries are in flight.
+
+### DB Schema Push (migrations 006 + 007)
+
+User applied both migrations via `supabase db push`:
+- Migration 006: UNIQUE constraints on `budgets(user_id, start_date)` and `categories(user_id, name)` with safe deduplication
+- Migration 007: `setup_completed` boolean column on `profiles` with backfill for existing users
+
+## Task Execution
+
+| Task | Name | Commit | Status |
+|------|------|--------|--------|
+| 1 | Create useFirstRunState.ts | 0c1105f | Complete |
+| 2 | DB schema push (migrations 006+007) | Manual (user) | Complete - user applied |
+| 3 | Human verification checkpoint | N/A | Approved by user |
+
+## Decisions Made
+
+1. **Zero-network-call design** -- Hook reads from existing React Query caches rather than making its own Supabase calls, avoiding redundant fetches.
+2. **Manual DB push** -- `supabase db push` required interactive confirmation; user ran it manually after checkpoint gate.
+
+## Deviations from Plan
+
+None -- plan executed exactly as written.
+
+## Known Stubs
+
+None -- hook is fully wired to existing data sources.
+
+## Verification Results
+
+- `export function useFirstRunState` found in hook file
+- Both `useCategories` and `useTemplate` imports present
+- `npx tsc --noEmit` passes with zero errors
+- Migration files 006 and 007 exist in supabase/migrations/
+- User confirmed DB constraints and setup_completed column are live in Supabase dashboard
+
+## Requirements Covered
+
+- **AUTO-01**: useFirstRunState provides first-run detection for auto-budget flow
+- **AUTO-03**: No hardcoded currency -- amounts are plain numbers throughout
+- **SETUP-01**: setup_completed column + backfill (plan 01) + useFirstRunState detection (plan 03)
+- **SETUP-02**: Preset library with 19 items delivered in plan 02
+
+## Self-Check: PASSED
+
+- [x] src/hooks/useFirstRunState.ts exists
+- [x] Commit 0c1105f verified in git log
+- [x] TypeScript compiles cleanly
+- [x] Migration files present on disk

+# Phase 6: Preset Data, First-Run Detection, and DB Safety - Context
+
+**Gathered:** 2026-04-20
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+The data layer is safe and ready — duplicate budget/category writes are impossible at the DB level, and the app correctly identifies first-run users. This phase delivers: DB uniqueness constraints, a setup_completed column with backfill migration, a useFirstRunState hook, and a preset budget item library (~15-20 items with i18n).
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Preset Library Content
+- Default amounts in EUR (matches existing profiles.currency default)
+- 4 income, 4 bill, 5 variable_expense, 2 debt, 2 saving, 2 investment items (~19 total)
+- i18n key format: `presets.{category_type}.{slug}` (e.g., `presets.bill.rent`)
+- Round number amounts (e.g., rent=1000, groceries=400) — easier to adjust, less presumptuous
+
+### First-Run Detection Logic
+- First-run triggers when user has zero categories OR zero template items (either missing = not set up)
+- New dedicated hook: `src/hooks/useFirstRunState.ts` (follows useCategories/useTemplate pattern)
+- Backfill via Supabase migration SQL: `UPDATE profiles SET setup_completed = true WHERE id IN (SELECT DISTINCT user_id FROM categories)`
+- Hook derives state from existing hooks (useCategories count + useTemplate items count) — no extra network call
+
+### DB Migration & Constraint Strategy
+- Cleanup step before adding unique constraints (deduplicate existing data safely)
+- Separate migration files: `006_uniqueness_constraints.sql` and `007_setup_completed.sql`
+- `setup_completed` column defaults to `false` — new signups start as not-setup; existing users backfilled to `true`
+- Unique constraint on budgets: `(user_id, start_date)` only — end_date always derived
+
+### Claude's Discretion
+- Exact preset item names and amounts (within the balanced category distribution)
+- German translation text for preset i18n keys
+- Order of migration operations within each file
+- Error handling approach for constraint violations in application code
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `src/hooks/useCategories.ts` — existing hook pattern to follow for useFirstRunState
+- `src/hooks/useTemplate.ts` — template data access, can derive "has template items" from this
+- `src/lib/types.ts` — type definitions for categories, templates, budgets
+- `supabase/migrations/001-005` — existing migration chain to extend
+
+### Established Patterns
+- Hooks use React Query with Supabase client
+- Category types enum: income, bill, variable_expense, debt, saving, investment
+- Template items reference categories via category_id
+- Profiles table auto-created via trigger on auth.users insert
+
+### Integration Points
+- `profiles` table needs new `setup_completed` boolean column
+- `budgets` table needs unique constraint on (user_id, start_date)
+- `categories` table needs unique constraint on (user_id, name)
+- New `src/data/presets.ts` file for preset library
+- New `src/hooks/useFirstRunState.ts` for first-run detection
+- i18n files need preset translation keys (en + de)
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Currency column in profiles is already `currency text not null default 'EUR'` — confirmed in 001_profiles.sql
+- The `handle_new_user()` trigger creates profiles on signup — setup_completed will be false by default for new users
+- Templates table already has `unique(user_id)` — one template per user is enforced

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|------------------|
+| AUTO-01 | User's monthly budget is auto-created from template when visiting a month for the first time | `useFirstRunState` hook detects zero-category / zero-template-item state; budgets unique constraint prevents duplicate auto-creation |
+| AUTO-03 | Auto-creation uses the user's configured currency, not a hardcoded default | `profiles.currency` confirmed as `text not null default 'EUR'` — hook/migration must not hardcode currency |
+| SETUP-01 | New user is guided through a 3-step wizard: income → recurring items → review | `setup_completed` column + backfill migration provides the flag Phase 7 wizard reads to decide whether to show onboarding |
+| SETUP-02 | User sees pre-filled common budget items with sensible default amounts (~15-20 items) | `src/data/presets.ts` delivers the curated item library with i18n keys and EUR amounts |
+</phase_requirements>
+
+---
+
+## Summary
+
+Phase 6 is a pure data/infrastructure layer — no new UI. It consists of four discrete deliverables: two Supabase migration files (uniqueness constraints + setup_completed column), a new TypeScript data file (`src/data/presets.ts`), a new React Query hook (`src/hooks/useFirstRunState.ts`), and additions to both i18n JSON files.
+
+The existing schema (verified against migrations 001–005) has no duplicate-prevention constraints on `budgets` or `categories`. The `profiles` table has no `setup_completed` column yet. The `templates` table already has `unique(user_id)`. All hook patterns follow `useQuery` + `useMutation` from `@tanstack/react-query` with the Supabase JS client — `useFirstRunState` will be read-only (query-only) and simpler than existing hooks.
+
+The main planning risk is the cleanup step before adding unique constraints: the deduplication SQL must run inside the same transaction as the `ADD CONSTRAINT` statement so the constraint cannot be violated by orphaned duplicates surviving the cleanup.
+
+**Primary recommendation:** Write migration 006 as a single transaction — DELETE duplicates, then ADD CONSTRAINT — so it's atomic and safe to run on existing databases.
+
+---
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Duplicate-write prevention | Database | — | Constraint enforced at DB level; application code is a secondary guard only |
+| First-run detection state | Frontend (React Query hook) | — | Derived from cached query data, no extra network call |
+| Preset item library | Frontend (static data file) | — | Static TypeScript module; no DB persistence, consumed by wizard (Phase 7) |
+| setup_completed persistence | Database (profiles table) | — | Boolean column; written by migration backfill and by wizard completion (Phase 7) |
+| i18n for preset names | Frontend (JSON files) | — | Follows existing en.json / de.json pattern |
+
+---
+
+## Standard Stack
+
+### Core (all already installed — verified against package.json)
+
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| `@tanstack/react-query` | (existing) | Server state, caching for useFirstRunState | Already used by all hooks |
+| `@supabase/supabase-js` | (existing) | DB client in hooks and migrations | Already used by all hooks |
+| PostgreSQL (via Supabase) | (existing) | Unique constraints, ALTER TABLE | Native DB feature; no library needed |
+
+No new npm packages are required for this phase.
+
+### Migration Tooling
+Supabase migrations are plain `.sql` files in `supabase/migrations/`. They are run in filename order by the Supabase CLI (`supabase db push`) or applied directly via the Supabase dashboard SQL editor. [VERIFIED: project migration files 001–005]

+├── 006_uniqueness_constraints.sql  # NEW
+└── 007_setup_completed.sql         # NEW
+```
+
+### Pattern 1: Safe Deduplication Before Unique Constraint
+
+**What:** Delete all but the oldest row per unique key before adding the constraint, wrapped in a transaction.
+**When to use:** Any migration adding a unique constraint on a table that may have existing duplicates.
+
+```sql
+-- Source: [VERIFIED: standard PostgreSQL CTE deduplication pattern]
+BEGIN;
+
+-- Keep only the oldest budget per (user_id, start_date)
+DELETE FROM budgets
+WHERE id NOT IN (
+  SELECT DISTINCT ON (user_id, start_date) id
+  FROM budgets
+  ORDER BY user_id, start_date, created_at ASC
+);
+
+ALTER TABLE budgets
+  ADD CONSTRAINT budgets_user_month_unique UNIQUE (user_id, start_date);
+
+-- Keep only the oldest category per (user_id, name)
+DELETE FROM categories
+WHERE id NOT IN (
+  SELECT DISTINCT ON (user_id, name) id
+  FROM categories
+  ORDER BY user_id, name, created_at ASC
+);
+
+ALTER TABLE categories
+  ADD CONSTRAINT categories_user_name_unique UNIQUE (user_id, name);
+
+COMMIT;
+```
+
+### Pattern 2: ADD COLUMN with Default + Immediate Backfill
+
+**What:** Add a boolean column with a default, then immediately UPDATE to backfill existing rows.
+**When to use:** Column needs a non-null default for new rows, but existing rows need a different value.
+
+```sql
+-- Source: [VERIFIED: standard PostgreSQL ALTER TABLE pattern]
+ALTER TABLE profiles
+  ADD COLUMN setup_completed boolean NOT NULL DEFAULT false;
+
+-- Backfill: existing users who have categories are considered set up
+UPDATE profiles
+SET setup_completed = true
+WHERE id IN (SELECT DISTINCT user_id FROM categories);
+```
+
+**Important:** `DEFAULT false` in the `ALTER TABLE` statement means the column is added atomically with `false` for all existing rows *before* the UPDATE runs. The UPDATE then flips the qualifying rows. Order matters here. [VERIFIED: PostgreSQL behavior]
+
+### Pattern 3: Derived State Hook (no extra network call)
+
+**What:** Build a hook that computes a boolean from two already-cached queries.
+**When to use:** When state can be inferred from data already loaded by sibling hooks.
+
+```typescript
+// Source: [VERIFIED: matches useCategories.ts + useTemplate.ts patterns in codebase]
+import { useCategories } from "@/hooks/useCategories"
+import { useTemplate } from "@/hooks/useTemplate"
+
+export function useFirstRunState() {
+  const { categories, loading: catLoading } = useCategories()
+  const { items, loading: tmplLoading } = useTemplate()
+
+  return {
+    isFirstRun: categories.length === 0 || items.length === 0,
+    loading: catLoading || tmplLoading,
+  }
+}
+```
+
+**Key insight:** `useCategories` caches under `["categories"]` and `useTemplate` caches under `["template"]` + `["template-items"]`. If those queries have already been called (e.g., by mounted pages), `useFirstRunState` returns instantly from cache — no extra Supabase round-trip. [VERIFIED: React Query staleTime default behavior]
+
+### Pattern 4: Preset Data File Shape
+
+**What:** Static TypeScript module exporting typed preset items.
+**When to use:** Read-only reference data consumed by the wizard UI (Phase 7).
+
+```typescript
+// Source: [ASSUMED — no existing presets.ts to verify against; shape inferred from types.ts]
+export interface PresetItem {
+  slug: string                // used to build i18n key: presets.{type}.{slug}
+  type: CategoryType          // from src/lib/types.ts
+  defaultAmount: number       // EUR, round number
+  item_tier: "fixed" | "variable"
+}
+
+export const PRESETS: PresetItem[] = [
+  // income (4)
+  { slug: "salary",         type: "income",           defaultAmount: 3000, item_tier: "fixed"    },
+  { slug: "freelance",      type: "income",           defaultAmount: 500,  item_tier: "variable" },
+  { slug: "rental_income",  type: "income",           defaultAmount: 800,  item_tier: "fixed"    },
+  { slug: "other_income",   type: "income",           defaultAmount: 200,  item_tier: "variable" },
+  // bill (4)
+  { slug: "rent",           type: "bill",             defaultAmount: 1000, item_tier: "fixed"    },
+  { slug: "electricity",    type: "bill",             defaultAmount: 80,   item_tier: "fixed"    },
+  { slug: "internet",       type: "bill",             defaultAmount: 40,   item_tier: "fixed"    },
+  { slug: "phone",          type: "bill",             defaultAmount: 30,   item_tier: "fixed"    },
+  // variable_expense (5)
+  { slug: "groceries",      type: "variable_expense", defaultAmount: 400,  item_tier: "variable" },
+  { slug: "transport",      type: "variable_expense", defaultAmount: 100,  item_tier: "variable" },
+  { slug: "dining_out",     type: "variable_expense", defaultAmount: 150,  item_tier: "variable" },
+  { slug: "health",         type: "variable_expense", defaultAmount: 50,   item_tier: "variable" },
+  { slug: "clothing",       type: "variable_expense", defaultAmount: 100,  item_tier: "variable" },
+  // debt (2)
+  { slug: "loan_repayment", type: "debt",             defaultAmount: 200,  item_tier: "fixed"    },
+  { slug: "credit_card",    type: "debt",             defaultAmount: 100,  item_tier: "fixed"    },
+  // saving (2)
+  { slug: "emergency_fund", type: "saving",           defaultAmount: 200,  item_tier: "fixed"    },
+  { slug: "vacation",       type: "saving",           defaultAmount: 100,  item_tier: "fixed"    },
+  // investment (2)
+  { slug: "etf",            type: "investment",       defaultAmount: 200,  item_tier: "fixed"    },
+  { slug: "pension",        type: "investment",       defaultAmount: 100,  item_tier: "fixed"    },
+]
+```
+
+### Pattern 5: i18n Key Structure for Presets
+
+The existing i18n files use a flat nested structure. Add a `"presets"` top-level key, nested by `category_type`, then `slug`. [VERIFIED: matches en.json structure]
+
+```json
+// en.json addition
+{
+  "presets": {
+    "income": {
+      "salary": "Salary",
+      "freelance": "Freelance Income",
+      "rental_income": "Rental Income",
+      "other_income": "Other Income"
+    },
+    "bill": {
+      "rent": "Rent",
+      "electricity": "Electricity",
+      "internet": "Internet",
+      "phone": "Phone"
+    },
+    "variable_expense": {
+      "groceries": "Groceries",
+      "transport": "Transport",
+      "dining_out": "Dining Out",
+      "health": "Health & Pharmacy",
+      "clothing": "Clothing"
+    },
+    "debt": {
+      "loan_repayment": "Loan Repayment",
+      "credit_card": "Credit Card"
+    },
+    "saving": {
+      "emergency_fund": "Emergency Fund",
+      "vacation": "Vacation Fund"
+    },
+    "investment": {
+      "etf": "ETF / Index Fund",
+      "pension": "Pension"
+    }
+  }
+}
+```
+
+### Anti-Patterns to Avoid
+
+- **Adding UNIQUE constraint without deduplication first:** Will fail with `duplicate key value violates unique constraint` on any DB with existing duplicate rows.
+- **Separate transaction for cleanup and constraint:** If cleanup succeeds but constraint ADD fails (e.g., missed a duplicate), the DB is left partially modified. Always wrap both in one `BEGIN/COMMIT`.
+- **isFirstRun computed at render without loading guard:** Returns `true` spuriously while queries are still in-flight (both lengths are 0). Always gate on `loading` before acting on `isFirstRun`.
+- **Hardcoding 'EUR' in presets.ts:** The preset amounts are EUR, but the label/currency displayed in the wizard must come from `profiles.currency`, not from presets.ts. Keep amounts as plain numbers.
+

+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Duplicate row prevention | Application-level upsert logic with SELECT-then-INSERT | PostgreSQL UNIQUE constraint | Race condition between SELECT and INSERT; DB constraint is atomic |
+| Query caching for derived state | Manual state tracking / local useState | React Query (already installed) | useCategories + useTemplate already cache — just consume the cached data |
+| i18n key resolution | Custom translation lookup | Existing i18n framework already in use | Check how `t()` is called in existing components and replicate |
+
+---
+
+## Common Pitfalls
+
+### Pitfall 1: DISTINCT ON Requires ORDER BY on the Same Columns
+
+**What goes wrong:** `SELECT DISTINCT ON (user_id, start_date)` without `ORDER BY user_id, start_date` throws a PostgreSQL error.
+**Why it happens:** PostgreSQL requires the DISTINCT ON expressions to be the leftmost ORDER BY expressions.
+**How to avoid:** Always write `ORDER BY user_id, start_date, created_at ASC` (or whichever tiebreaker). [VERIFIED: PostgreSQL docs behavior]
+**Warning signs:** `ERROR: SELECT DISTINCT ON expressions must match initial ORDER BY expressions`
+
+### Pitfall 2: isFirstRun is True During Loading
+
+**What goes wrong:** `categories.length === 0 || items.length === 0` is `true` while data is still loading (both arrays are empty defaults). If Phase 7 wizard triggers on `isFirstRun`, it fires on every page load while data fetches.
+**Why it happens:** `useCategories` returns `[]` as default; hook consumers see `isFirstRun = true` before the query resolves.
+**How to avoid:** Export `loading` from `useFirstRunState`. Callers must check `!loading && isFirstRun` before acting. [VERIFIED: useCategories.ts returns `query.data ?? []`]
+**Warning signs:** Wizard flashes on every load for users who have data.
+
+### Pitfall 3: Backfill Misses Users Without Categories
+
+**What goes wrong:** The backfill SQL sets `setup_completed = true` only for users who have categories. A v1.0 user who created a template but no categories would remain `false` and see the wizard on first v2.0 login.
+**Why it happens:** The backfill uses `categories` as the signal; it's possible (though unlikely in v1.0) to have a template with no categories.
+**How to avoid:** The agreed logic (zero categories OR zero template items = first run) means a user with template items but no categories is legitimately not set up. Verify that v1.0 users always created categories before template items. If uncertain, widen the backfill:
+  ```sql
+  UPDATE profiles SET setup_completed = true
+  WHERE id IN (
+    SELECT DISTINCT user_id FROM categories
+    UNION
+    SELECT t.user_id FROM templates t
+    INNER JOIN template_items ti ON ti.template_id = t.id
+  );
+  ```
+**Warning signs:** v1.0 users reporting wizard appearing unexpectedly.
+
+### Pitfall 4: Profile Type Missing setup_completed
+
+**What goes wrong:** After migration 007 adds `setup_completed`, the TypeScript `Profile` interface in `src/lib/types.ts` still lacks the field. Any code reading `profile.setup_completed` gets a TypeScript error or `undefined`.
+**Why it happens:** Migrations and TypeScript types are manually kept in sync — there is no auto-generation in this project.
+**How to avoid:** Include updating `src/lib/types.ts` as an explicit task in the plan. Add `setup_completed: boolean` to the `Profile` interface. [VERIFIED: types.ts inspected — field absent]
+**Warning signs:** TypeScript compiler error on `profile.setup_completed`.
+
+### Pitfall 5: Migration File Ordering
+
+**What goes wrong:** A migration named `006_...` that runs after one named `007_...` (or vice versa) due to filename sort.
+**Why it happens:** Supabase CLI applies migrations in lexicographic filename order.
+**How to avoid:** Uniqueness constraints must come in `006_...` and setup_completed in `007_...` because the backfill in 007 reads from `categories` — which needs to exist and be constraint-safe first. The order is correct as specified. [VERIFIED: existing migrations 001–005 confirm naming convention]
+
+---
+
+## Code Examples
+
+### Confirmed: Category Type Enum Values
+
+From `002_categories.sql` and `src/lib/types.ts` [VERIFIED]:
+```
+'income' | 'bill' | 'variable_expense' | 'debt' | 'saving' | 'investment'
+```
+Preset items must use these exact string values as `type`.
+
+### Confirmed: profiles Table Columns (before migration 007)
+
+From `001_profiles.sql` [VERIFIED]:
+```
+id, display_name, locale, currency, created_at, updated_at
+```
+No `setup_completed` column exists yet. Migration 007 adds it.
+
+### Confirmed: budgets Table (before migration 006)
+
+From `004_budgets.sql` [VERIFIED]:
+- No unique constraint on `(user_id, start_date)`.
+- `start_date date not null`, `end_date date not null` — both present.
+
+### Confirmed: categories Table (before migration 006)
+
+From `002_categories.sql` [VERIFIED]:
+- No unique constraint on `(user_id, name)`.
+- Only a `categories_user_id_idx` index exists.

+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Application-level duplicate checks | DB-level UNIQUE constraint | This phase | Eliminates race conditions; constraint error surfaces as Supabase PostgREST error code `23505` |
+| No first-run concept | `setup_completed` + `useFirstRunState` | This phase | Enables Phase 7 wizard to show only to new users |
+
+---
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | `item_tier: "one_off"` is excluded from presets (only "fixed" and "variable") | Pattern 4 | If wizard allows one_off presets, the type needs updating — but `template_items.item_tier` check constraint already limits to `('fixed', 'variable')` so this is safe |
+| A2 | No existing duplicate budgets or categories in production data | Migration 006 | If duplicates exist the DELETE+CONSTRAINT pattern handles them; risk is low, the cleanup step is exactly for this |
+| A3 | The i18n library in use supports nested key access via dot notation (e.g., `t('presets.bill.rent')`) | i18n pattern | If it uses a flat key format, key structure needs adjustment — check existing `t()` calls in components before writing keys |
+
+---
+
+## Open Questions
+
+1. **How does the app call `t()`?**
+   - What we know: en.json and de.json use nested objects (e.g., `categories.types.income`).
+   - What's unclear: Whether translation is `t('categories.types.income')` (dot-path) or `t('categories')['types']['income']`. Most react-i18next setups use dot-path.
+   - Recommendation: Before writing i18n keys, grep one existing `t()` call in the codebase to confirm syntax. Plan task should include this verification.
+
+2. **Are there any existing v1.0 users in production?**
+   - What we know: The blocker in STATE.md says "existing v1.0 users must not see the wizard on first v2.0 login."
+   - What's unclear: Whether production has real user rows in `profiles` or if this is a personal/dev-only app.
+   - Recommendation: The migration is written defensively regardless — backfill runs on all qualifying rows, so there's no harm if the table is empty.
+

+
+## Environment Availability
+
+Step 2.6: SKIPPED (no new external dependencies — all tools are existing: Supabase CLI, PostgreSQL, Node/TypeScript toolchain already in use by the project).

+
+## Validation Architecture
+
+### Test Framework
+
+| Property | Value |
+|----------|-------|
+| Framework | None detected — no vitest.config.*, jest.config.*, or test scripts in package.json |
+| Config file | None — Wave 0 must create if tests are written |
+| Quick run command | N/A |
+| Full suite command | N/A |
+
+### Phase Requirements → Test Map
+
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| AUTO-01 | `useFirstRunState` returns `isFirstRun=true` when categories=[] | unit | `vitest run src/hooks/useFirstRunState.test.ts` | ❌ Wave 0 |
+| AUTO-01 | `useFirstRunState` returns `isFirstRun=false` when categories and items present | unit | `vitest run src/hooks/useFirstRunState.test.ts` | ❌ Wave 0 |
+| AUTO-01 | `useFirstRunState` returns `loading=true` while queries in flight | unit | `vitest run src/hooks/useFirstRunState.test.ts` | ❌ Wave 0 |
+| SETUP-02 | `PRESETS` exports exactly 19 items | unit | `vitest run src/data/presets.test.ts` | ❌ Wave 0 |
+| SETUP-02 | Each preset has valid `type` from CategoryType enum | unit | `vitest run src/data/presets.test.ts` | ❌ Wave 0 |
+| SETUP-02 | Each preset has `item_tier` of `fixed` or `variable` (not `one_off`) | unit | `vitest run src/data/presets.test.ts` | ❌ Wave 0 |
+| AUTO-03 | `Profile.setup_completed` TypeScript type is boolean | compile-time | `tsc --noEmit` | ❌ Wave 0 (after types.ts update) |
+| DB constraints | Unique constraint SQL — not unit-testable without Supabase local instance | manual | Supabase local dev + insert duplicate | N/A |
+
+### Sampling Rate
+- **Per task commit:** `tsc --noEmit` (type safety at minimum)
+- **Per wave merge:** `vitest run` (once vitest is set up)
+- **Phase gate:** All passing before `/gsd-verify-work`
+
+### Wave 0 Gaps
+- [ ] `vitest` not installed — install: `npm install -D vitest @vitest/ui`
+- [ ] `src/hooks/useFirstRunState.test.ts` — covers AUTO-01 loading guard and isFirstRun logic
+- [ ] `src/data/presets.test.ts` — covers SETUP-02 count, type validity, item_tier validity
+- [ ] `vitest.config.ts` — framework config (or add `"test"` to `vite.config.ts`)

+
+## Security Domain
+
+### Applicable ASVS Categories
+
+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | no | — |
+| V3 Session Management | no | — |
+| V4 Access Control | yes | Supabase RLS already enabled on all tables — new constraints do not bypass RLS |
+| V5 Input Validation | no | No new user-facing input in this phase |
+| V6 Cryptography | no | — |
+
+### Known Threat Patterns
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| Duplicate budget creation via parallel requests | Tampering | UNIQUE constraint on `(user_id, start_date)` — DB rejects second insert atomically |
+| First-run flag manipulation (client sets setup_completed) | Elevation of privilege | RLS policy `"Users can update own profile"` — user can update their own row; acceptable since setup_completed is not a security gate, only a UX flag |
+
+---
+
+## Sources
+
+### Primary (HIGH confidence)
+- `supabase/migrations/001_profiles.sql` — profiles table schema, trigger, no setup_completed column confirmed
+- `supabase/migrations/002_categories.sql` — categories table schema, no unique constraint on (user_id, name) confirmed
+- `supabase/migrations/004_budgets.sql` — budgets table schema, no unique constraint on (user_id, start_date) confirmed
+- `src/hooks/useCategories.ts` — hook pattern, query key ["categories"], default returns []
+- `src/hooks/useTemplate.ts` — hook pattern, query keys, items default []
+- `src/lib/types.ts` — CategoryType values, Profile interface (no setup_completed), all confirmed
+- `src/i18n/en.json`, `de.json` — i18n structure and nesting pattern confirmed
+- `.planning/config.json` — nyquist_validation: true confirmed
+
+### Secondary (MEDIUM confidence)
+- PostgreSQL DISTINCT ON + ORDER BY requirement — standard behavior, well-documented
+
+### Tertiary (LOW confidence)
+- A3: i18n dot-path notation — inferred from JSON structure; needs grep verification
+
+---
+
+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH — all libraries verified as already installed
+- Architecture: HIGH — all schema details verified against actual migration files and hook source
+- Pitfalls: HIGH — derived from direct inspection of existing code and standard PostgreSQL semantics
+- Preset content: MEDIUM — exact amounts and slugs are at Claude's discretion; structure is HIGH confidence

+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Attempting to create two budgets for the same user and month is rejected at the DB level | VERIFIED | `006_uniqueness_constraints.sql` contains `ADD CONSTRAINT budgets_user_month_unique UNIQUE (user_id, start_date)` wrapped in BEGIN/COMMIT. User confirmed DB push completed successfully. |
+| 2 | Attempting to create two categories with the same name for the same user is rejected at the DB level | VERIFIED | `006_uniqueness_constraints.sql` contains `ADD CONSTRAINT categories_user_name_unique UNIQUE (user_id, name)` with safe deduplication DELETE. User confirmed DB push completed. |
+| 3 | All existing v1.0 users have `profiles.setup_completed = true` after backfill | VERIFIED | `007_setup_completed.sql` adds column `boolean NOT NULL DEFAULT false` then runs UPDATE with UNION covering both `categories` and `template_items` tables. User confirmed DB push applied. |
+| 4 | `useFirstRunState` hook returns `true` only for users with zero categories or zero template items | VERIFIED | `src/hooks/useFirstRunState.ts` exports function returning `{ isFirstRun: categories.length === 0 \|\| items.length === 0, loading: catLoading \|\| tmplLoading }`. Derives from `useCategories()` and `useTemplate()` caches. `tsc --noEmit` passes. |
+| 5 | `src/data/presets.ts` contains ~15-20 curated budget items with i18n translation keys | VERIFIED | 19 items (4 income, 4 bill, 5 variable_expense, 2 debt, 2 saving, 2 investment). `en.json` and `de.json` both have `presets` key with 19 slugs across 6 type categories. Both JSON files parse cleanly. |

+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|-----------|-------------|--------|----------|
+| AUTO-01 | 06-01, 06-03 | Auto-budget uses template on first month visit | SATISFIED (Phase 6 portion) | Budgets unique constraint prevents duplicates; useFirstRunState detects first-run. Full auto-creation in Phase 8. |
+| AUTO-03 | 06-01, 06-02 | Auto-creation uses user's configured currency | SATISFIED (Phase 6 portion) | Preset amounts are plain EUR numbers with no currency symbol. Profile has currency field. Full currency usage in Phase 8. |
+| SETUP-01 | 06-01, 06-03 | New user guided through wizard | SATISFIED (Phase 6 portion) | setup_completed column + backfill identifies existing users. useFirstRunState hook detects new users. Wizard UI in Phase 7. |
+| SETUP-02 | 06-02 | User sees pre-filled common budget items | SATISFIED (Phase 6 portion) | 19 preset items in PRESETS array with en/de translations. Wizard display in Phase 7. |
+
+No orphaned requirements found -- all 4 IDs (AUTO-01, AUTO-03, SETUP-01, SETUP-02) appear in plan frontmatter and are traced to REQUIREMENTS.md.
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| (none) | - | - | - | No anti-patterns detected in any phase 6 artifact |
+
+### Human Verification Required
+
+### 1. Budget Unique Constraint Enforcement
+
+**Test:** In Supabase SQL editor, INSERT two budget rows with the same `user_id` and `start_date`.
+**Expected:** Second INSERT fails with error code 23505 (unique_violation).
+**Why human:** Requires running Supabase instance with live DB. Note: User already confirmed DB push succeeded, but runtime constraint rejection is a behavioral check.
+
+### 2. Category Unique Constraint Enforcement
+
+**Test:** In Supabase SQL editor, INSERT two category rows with the same `user_id` and `name`.
+**Expected:** Second INSERT fails with error code 23505 (unique_violation).
+**Why human:** Requires running Supabase instance with live DB.
+
+### 3. Backfill Correctness for Existing Users
+
+**Test:** In Supabase Table Editor, check `profiles` rows for users who existed before migration 007.
+**Expected:** Any user with existing categories or template items has `setup_completed = true`. New test users have `setup_completed = false`.
+**Why human:** Requires inspecting live database state.
+
+### Gaps Summary
+
+No gaps found. All 5 roadmap success criteria are verified at the code/artifact level. Two artifacts (useFirstRunState hook and PRESETS array) are intentionally orphaned -- they are consumed by Phase 7 (Setup Wizard), which is the next phase.
+
+Three items require human verification against the live database: budget constraint enforcement, category constraint enforcement, and backfill correctness. These are behavioral checks that cannot be verified by static code analysis alone.

+<objective>
+Build the setup wizard page shell, state management hook, and all UI components for the 3-step wizard (income, recurring items with live allocation, review placeholder).
+
+Purpose: Establishes the wizard's visual structure, localStorage persistence, and all interactive components. Plan 02 will add the ReviewStep and completion/redirect logic on top of this foundation.
+Output: A navigable 3-step wizard at /setup (not yet routed) with working state persistence and live allocation calculation.

+  <action>
+1. Install shadcn checkbox:
+```bash
+npx shadcn@latest add checkbox
+```
+
+2. Create `src/hooks/useWizardState.ts`:
+```typescript
+import { useState, useEffect } from "react"
+import { PRESETS } from "@/data/presets"
+
+export interface WizardState {
+  currentStep: 1 | 2 | 3
+  income: number
+  selectedItems: Record<string, { checked: boolean; amount: number }>
+}
+
+const STORAGE_KEY = (userId: string) => `setup-wizard-${userId}`
+
+function getDefaultState(): WizardState {
+  const selectedItems: Record<string, { checked: boolean; amount: number }> = {}
+  for (const preset of PRESETS) {
+    selectedItems[preset.slug] = {
+      checked: preset.type === "bill" || preset.type === "variable_expense",
+      amount: preset.defaultAmount,
+    }
+  }
+  return { currentStep: 1, income: 3000, selectedItems }
+}
+
+export function useWizardState(userId: string) {
+  const [state, setState] = useState<WizardState>(() => {
+    try {
+      const saved = localStorage.getItem(STORAGE_KEY(userId))
+      if (saved) {
+        const parsed = JSON.parse(saved)
+        // Validate shape
+        if (parsed && typeof parsed.currentStep === "number" && typeof parsed.income === "number" && parsed.selectedItems) {
+          return parsed as WizardState
+        }
+      }
+    } catch { /* ignore corrupt data */ }
+    return getDefaultState()
+  })
+
+  useEffect(() => {
+    localStorage.setItem(STORAGE_KEY(userId), JSON.stringify(state))
+  }, [state, userId])
+
+  const setStep = (step: 1 | 2 | 3) => setState(s => ({ ...s, currentStep: step }))
+  const setIncome = (income: number) => setState(s => ({ ...s, income }))
+  const toggleItem = (slug: string) => setState(s => ({
+    ...s,
+    selectedItems: {
+      ...s.selectedItems,
+      [slug]: { ...s.selectedItems[slug], checked: !s.selectedItems[slug].checked },
+    },
+  }))
+  const setItemAmount = (slug: string, amount: number) => setState(s => ({
+    ...s,
+    selectedItems: {
+      ...s.selectedItems,
+      [slug]: { ...s.selectedItems[slug], amount },
+    },
+  }))
+  const clearState = () => {
+    localStorage.removeItem(STORAGE_KEY(userId))
+  }
+
+  return { state, setStep, setIncome, toggleItem, setItemAmount, clearState }
+}
+```
+
+3. Add i18n keys to `src/i18n/en.json` — add a `"setup"` object at the top level:
+```json
+"setup": {
+  "title": "Set up your budget",
+  "step1": {
+    "title": "Monthly Income",
+    "description": "How much do you earn each month?",

+    "helper": "Enter your total monthly take-home pay",
+    "validation": "Please enter a positive income amount"
+  },

+    "error": "Could not save your template. Please try again.",
+    "partialError": "Some items could not be saved. Check your template page."
+  }
+}
+```
+
+4. Add equivalent German keys to `src/i18n/de.json`:
+```json

+  },
+  "steps": {

+  <action>
+Create the following components in `src/components/setup/`:
+
+**1. WizardStepper.tsx:**
+- Props: `currentStep: 1|2|3`, `onStepClick: (step: 1|2|3) => void`
+- Renders 3 circles in a row connected by lines
+- Active step: `bg-primary text-primary-foreground` with number (14px/600)
+- Completed step (step < currentStep): `bg-primary text-primary-foreground` with lucide `Check` icon (16px)
+- Upcoming step (step > currentStep): `bg-muted text-muted-foreground border border-border`
+- Connector line between: `h-px w-16` — completed segment `bg-primary`, upcoming `bg-border`
+- Step labels below circles: text-xs font-semibold, active `text-foreground`, others `text-muted-foreground`
+- Labels from i18n: `t("setup.steps.1")`, `t("setup.steps.2")`, `t("setup.steps.3")`
+- Clicking a completed step or current step calls onStepClick. Future steps: no action, cursor-default.
+- Wrap in `role="navigation" aria-label="Setup progress"`
+- Circle dimensions: `w-8 h-8` (32px)
+- Overall layout: `flex items-center justify-center gap-0` with step groups `flex flex-col items-center gap-1` separated by connector lines
+- Margin below: handled by parent (mb-6)
+
+**2. IncomeStep.tsx:**
+- Props: `income: number`, `onIncomeChange: (val: number) => void`, `currency: string`, `error: string | null`
+- Renders card content for step 1
+- Label: `t("setup.step1.incomeLabel")` (14px/600)
+- Input row: `flex items-center gap-2`
+  - Input: `type="number"`, `className="w-full text-right text-lg"`, value={income}, onChange converts to number
+  - Currency suffix: `<span className="text-muted-foreground text-sm">{currency}</span>`
+- Helper text: `t("setup.step1.helper")` in `text-sm text-muted-foreground`
+- If `error` is truthy: show `<p className="text-sm text-destructive">{error}</p>` below input
+- `aria-describedby` on input pointing to helper and error elements
+
+**3. AllocationBar.tsx:**
+- Props: `remaining: number`, `currency: string`
+- Layout: `sticky top-0 z-10 flex justify-between items-center py-3 px-4 bg-muted border-b border-border rounded-none`
+- Left: `<span className="text-sm font-semibold">{t("setup.step2.remaining")}</span>`
+- Right: formatted amount using `Intl.NumberFormat` with currency
+  - `remaining >= 0`: `className="text-base font-semibold text-on-budget"`
+  - `remaining < 0`: `className="text-base font-semibold text-destructive"`
+- Add `aria-live="polite"` on the amount element
+
+**4. CategoryGroupHeader.tsx:**
+- Props: `type: CategoryType`, `label: string`, `count: number`
+- Layout: `flex items-center gap-2 pt-4 pb-2`
+- Colored dot: `w-2.5 h-2.5 rounded-full` with inline style `backgroundColor: var(--color-${type.replace('_', '-')})`
+  - Map types to CSS vars: income -> `--color-income`, bill -> `--color-bill`, variable_expense -> `--color-variable-expense`, debt -> `--color-debt`, saving -> `--color-saving`, investment -> `--color-investment`
+- Label: `<span className="text-sm font-semibold">{label}</span>`
+- Count: `<span className="text-xs text-muted-foreground">({count} items)</span>`
+- Below: `<Separator />` from shadcn
+
+**5. PresetItemRow.tsx:**
+- Props: `slug: string`, `type: CategoryType`, `checked: boolean`, `amount: number`, `onToggle: () => void`, `onAmountChange: (val: number) => void`
+- Layout: `flex items-center gap-3 py-2.5 px-1`
+- Checkbox: shadcn `<Checkbox checked={checked} onCheckedChange={onToggle} />`
+- Item name: `<span className="flex-1 text-sm">{t(\`presets.${type}.${slug}\`)}</span>`
+- Category badge: `<Badge variant="outline" className="text-xs" style={{ borderLeftWidth: '3px', borderLeftColor: \`var(--color-${type.replace('_', '-')})\` }}>{t(\`categories.types.${type}\`)}</Badge>`
+- Amount input: `<Input type="number" className="w-24 text-right" value={amount} onChange={...} disabled={!checked} />`
+  - When disabled: add `bg-muted text-muted-foreground opacity-50` classes
+
+**6. RecurringItemsStep.tsx:**
+- Props: `selectedItems: Record<string, { checked: boolean; amount: number }>`, `income: number`, `currency: string`, `onToggle: (slug: string) => void`, `onAmountChange: (slug: string, amount: number) => void`
+- Groups PRESETS by type using: `Object.groupBy(PRESETS, (p) => p.type)` — if Object.groupBy not available, use manual reduce
+- Order groups: `["income", "bill", "variable_expense", "debt", "saving", "investment"]`
+- Renders AllocationBar at top (sticky)
+- For each group: CategoryGroupHeader + list of PresetItemRow
+- Wrap each group in `<fieldset>` with `<legend className="sr-only">{groupLabel}</legend>`
+- Compute remaining: `income - sum of all checked items' amounts`
+
+**7. SetupPage.tsx** (page orchestrator):
+- Imports useAuth, useWizardState, useTranslation, WizardStepper, IncomeStep, RecurringItemsStep
+- Gets userId from `useAuth()` -> `user.id`
+- Gets currency from profile: `profile?.currency ?? "EUR"`
+- Uses `useWizardState(userId)` for state management
+- Layout: `<div className="flex min-h-screen items-center justify-center bg-background p-4"><div className="w-full max-w-2xl">`
+- Renders WizardStepper above the card
+- Card: `<Card className="w-full border border-border shadow-sm">`
+  - CardHeader: step title (heading 20px/600) + step description (body 14px/400 text-muted-foreground)
+  - CardContent: renders active step component based on `state.currentStep`
+  - Bottom nav: `flex justify-between items-center pt-4 border-t border-border`
+    - Left side: Go Back button (variant="ghost", hidden on step 1) + Skip Step button (variant="ghost" text-muted-foreground)
+    - Right side: Next Step button (variant="default")
+- Step 1 Next: validates income > 0, shows error if invalid, otherwise advances to step 2
+- Step 2 Next: no validation, advances to step 3
+- Step 3: shows placeholder text "Review step coming in next plan" (will be replaced in Plan 02)
+- Below card: "Skip setup" link: `<button className="mt-4 text-sm text-muted-foreground underline block mx-auto">{t("setup.skipSetup")}</button>`
+- Skip step on step 1: advance to step 2. Skip step on step 2: advance to step 3.
+- Clicking completed stepper steps calls `setStep(step)`

+# Phase 07 Plan 01: Setup Wizard UI Shell Summary
+
+LocalStorage-synced 3-step wizard with income input, grouped preset checklist (19 items), live allocation bar, and horizontal stepper navigation.
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| 1 | bbcb07f | useWizardState hook, i18n keys (EN+DE), shadcn checkbox |
+| 2 | e141197 | All 7 wizard UI components and SetupPage orchestrator |
+
+## What Was Built
+
+1. **useWizardState hook** - Manages wizard step, income, and item selections in localStorage keyed by userId. Validates JSON shape on load (T-07-01 mitigation). Bills and variable_expense items pre-checked by default.
+
+2. **WizardStepper** - Horizontal 1-2-3 stepper with circles, connector lines, and step labels. Completed steps are clickable; future steps are disabled.
+
+3. **IncomeStep** - Number input pre-filled with 3000, currency suffix from profile, helper text, and inline validation error display.
+
+4. **AllocationBar** - Sticky bar showing remaining = income - sum(checked amounts). Green when positive, red (destructive) when negative. aria-live="polite" for screen readers.
+
+5. **CategoryGroupHeader** - Colored dot + label + item count for each of the 6 category types.
+
+6. **PresetItemRow** - Checkbox + preset name (i18n) + category badge with colored border + editable amount input (disabled when unchecked).
+
+7. **RecurringItemsStep** - Groups all 19 PRESETS into 6 category sections with AllocationBar at top.
+
+8. **SetupPage** - Page orchestrator: centered card layout (max-w-2xl), loads profile for currency, renders stepper + active step, handles Next/Back/Skip navigation with income validation.
+
+## i18n
+
+All wizard copy added under `setup.*` namespace in both `en.json` and `de.json` (35 keys each). German translations use proper umlauts and natural phrasing.
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Known Stubs
+
+| File | Line | Stub | Reason |
+|------|------|------|--------|
+| src/pages/SetupPage.tsx | Step 3 content | "Review step coming in next plan" placeholder | Plan 02 will implement ReviewStep and completion logic |
+| src/pages/SetupPage.tsx | Skip setup button | No-op onClick | Plan 02 will wire skip to mark setup_completed and redirect |
+| src/pages/SetupPage.tsx | Complete button | Disabled, no handler | Plan 02 will implement completion sequence |
+
+These stubs are intentional -- Plan 02 explicitly owns the ReviewStep, completion logic, routing, and redirect.

+---
+
+<objective>
+Add the ReviewStep component, wire wizard completion logic (creating categories + template items), add skip functionality, register the /setup route, and add first-run redirect in DashboardPage.
+
+Purpose: Completes the wizard end-to-end — a new user is redirected to /setup, can navigate all 3 steps, and either completes (creating template data) or skips.
+Output: Fully functional setup wizard accessible via /setup with working completion and skip flows.

+  <action>
+**1. Create `src/components/setup/ReviewStep.tsx`:**
+
+Props: `income: number`, `selectedItems: Record<string, { checked: boolean; amount: number }>`, `currency: string`
+
+Layout:
+- Income row: `flex justify-between py-2` — left: `t("setup.step3.incomeLabel")` (14px/600), right: formatted income (14px/600)
+- `<Separator />`
+- Group checked items by type (same order: income, bill, variable_expense, debt, saving, investment). Only show groups that have at least one checked item.
+- For each group: render CategoryGroupHeader (import from `./CategoryGroupHeader`), then for each checked item in group: `<div className="flex justify-between py-1.5 px-1"><span className="text-sm">{t(\`presets.${type}.${slug}\`)}</span><span className="text-sm text-right">{formattedAmount}</span></div>`
+- `<Separator />`
+- Totals: `space-y-1 pt-2`
+  - Total expenses row: `flex justify-between` with label `t("setup.step3.totalLabel")` (14px/600) and sum of checked amounts
+  - Remaining row: `flex justify-between` with label `t("setup.step3.remainingLabel")` (16px/600), value colored `text-on-budget` if >= 0, `text-destructive` if < 0
+- If no items checked: show `<p className="text-sm text-muted-foreground py-4">{t("setup.step3.empty")}</p>` instead of groups
+
+Use `Intl.NumberFormat` with `style: "currency"` and the `currency` prop for all amount formatting.
+
+Import PRESETS from `@/data/presets` to map slugs to types for grouping.
+
+**2. Update `src/pages/SetupPage.tsx` to add:**
+
+a) Import ReviewStep, useCategories, useTemplate, useQueryClient, toast (from sonner), supabase (from @/lib/supabase), Navigate (from react-router-dom), useNavigate
+
+b) Add `completing` state: `const [completing, setCompleting] = useState(false)`
+
+c) Replace the step 3 placeholder with `<ReviewStep income={state.income} selectedItems={state.selectedItems} currency={currency} />`
+
+d) Change the right-side button on step 3 from "Next Step" to "Complete Setup" (`t("setup.complete")`), disabled when `completing`
+
+e) Add completion handler `handleComplete`:
+```typescript
+async function handleComplete() {
+  setCompleting(true)
+  try {
+    const queryClient = useQueryClient() // already declared at top
+    const checkedItems = PRESETS.filter(p => state.selectedItems[p.slug]?.checked)
+    
+    // 1. Determine unique category types needed
+    const typesNeeded = [...new Set(checkedItems.map(i => i.type))]
+    
+    // 2. Create one category per type (use i18n label as name)
+    const categoryMap: Record<string, string> = {}
+    for (const type of typesNeeded) {
+      try {
+        const cat = await create.mutateAsync({ name: t(`categories.types.${type}`), type })
+        categoryMap[type] = cat.id
+      } catch (e: any) {
+        // Unique constraint violation (23505) = category already exists, fetch it
+        if (e?.code === "23505" || e?.message?.includes("duplicate")) {

+          if (existing) categoryMap[type] = existing.id
+        } else {
+          throw e
+        }
+      }
+    }
+    
+    // 3. If categories were fetched from cache but not found, refetch
+    if (Object.keys(categoryMap).length < typesNeeded.length) {
+      await queryClient.invalidateQueries({ queryKey: ["categories"] })
+      // Remaining types need fresh data — handled by the existing entries
+    }
+    
+    // 4. Create template items for each checked preset
+    let partialFailure = false
+    for (const item of checkedItems) {
+      try {
+        await createItem.mutateAsync({
+          category_id: categoryMap[item.type],
+          item_tier: item.item_tier,
+          budgeted_amount: state.selectedItems[item.slug].amount,
+        })
+      } catch {
+        partialFailure = true
+      }
+    }
+    
+    // 5. Mark setup complete
+    await supabase.from("profiles").update({ setup_completed: true }).eq("id", user!.id)
+    
+    // 6. Clear wizard state
+    clearState()
+    
+    // 7. Invalidate queries to prevent redirect loop
+    await queryClient.invalidateQueries({ queryKey: ["categories"] })
+    await queryClient.invalidateQueries({ queryKey: ["template-items"] })
+    
+    // 8. Toast and redirect
+    if (partialFailure) {
+      toast.error(t("setup.toast.partialError"))
+    } else {
+      toast.success(t("setup.toast.success"))
+    }
+    navigate("/", { replace: true })
+  } catch {
+    toast.error(t("setup.toast.error"))
+  } finally {
+    setCompleting(false)
+  }
+}
+```
+
+f) Add skip handler `handleSkipSetup`:
+```typescript
+async function handleSkipSetup() {
+  clearState()
+  await supabase.from("profiles").update({ setup_completed: true }).eq("id", user!.id)
+  navigate("/", { replace: true })
+}
+```
+
+g) Wire "Skip setup" button below card to call `handleSkipSetup`
+
+h) Wire "Skip Step" on step 3 to also call `handleSkipSetup` (per UI-SPEC: "On step 3 skip: same as Skip setup")
+
+i) Disable Go Back, Skip Step, and Complete Setup buttons when `completing` is true
+
+j) Add `useCategories()` call at component top level to get `create` mutation and `categories` array. Add `useTemplate()` to ensure template row exists before completion (Pitfall 5).
+
+k) Get `useQueryClient()` at component top level (not inside handler).

+# Phase 07 Plan 02: Setup Wizard Completion and Routing Summary
+
+ReviewStep with grouped read-only summary, wizard completion logic (category + template item creation with duplicate handling), skip flow, /setup route registration, and first-run redirect from dashboard.
+
+## Commits
+
+| Task | Commit | Description |
+|------|--------|-------------|
+| 1 | 396d342 | ReviewStep component and wizard completion/skip logic |
+| 2 | 6b75f14 | Register /setup route and add first-run redirect |
+
+## What Was Built
+
+1. **ReviewStep** - Read-only summary component showing income, grouped checked items by category type, total expenses, and remaining balance. Uses Intl.NumberFormat for currency formatting. Remaining is colored green (text-on-budget) when positive, red (text-destructive) when negative.
+
+2. **Wizard Completion Logic** - handleComplete creates one category per needed type (handles 23505 duplicate constraint), creates template items for all checked presets, marks profiles.setup_completed=true, clears localStorage wizard state, invalidates React Query cache, shows toast, and redirects to dashboard.
+
+3. **Skip Flow** - handleSkipSetup clears localStorage, marks setup_completed=true without creating any data, and redirects to dashboard.
+
+4. **Double-submit Prevention** - `completing` state disables all buttons during API calls (T-07-04 mitigation).
+
+5. **/setup Route** - Registered in App.tsx as a protected standalone page (inside ProtectedRoute, outside AppLayout). Unauthenticated users are redirected to /login (T-07-06 mitigation).
+
+6. **First-run Redirect** - DashboardPage uses useFirstRunState to detect users with no categories/template items and redirects them to /setup. Shows DashboardSkeleton during loading.
+
+7. **Redirect Loop Prevention** - Query invalidation for ["categories"] and ["template-items"] after completion ensures useFirstRunState reads fresh data showing isFirstRun=false (T-07-07 mitigation).
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Fixed React hooks rule violation in DashboardPage**
+- **Found during:** Task 2
+- **Issue:** Plan instructed placing early returns before useMonthParam/useBudgets calls, which violates React rules of hooks (hooks cannot be called conditionally)
+- **Fix:** Moved all hook calls (useMonthParam, useBudgets, useMemo) above the early return statements
+- **Files modified:** src/pages/DashboardPage.tsx
+- **Commit:** 6b75f14
+
+## Known Stubs
+
+None - all stubs from Plan 01 have been resolved.

+# Phase 7: Setup Wizard - Context
+
+**Gathered:** 2026-04-20
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+A new user can set up their budget template in under 3 minutes by following a guided 3-step wizard with pre-filled common items and a live running balance. The wizard auto-redirects first-run users (detected by useFirstRunState), creates categories and template items on completion, persists state across refreshes, and supports skip at any point. Bilingual (EN/DE) via existing i18n system.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Wizard Layout & Navigation
+- Numbered horizontal stepper (1-2-3 bar at top) — minimal, clear progress indicator
+- Centered card layout (max-w-2xl) on clean background — consistent with auth pages
+- Next/Back buttons at bottom + step indicator is clickable for going back
+- Same centered card on mobile, full-width breakpoint — project is desktop-first
+
+### Income Step (Step 1)
+- Single "monthly net income" number input — simplest mental model
+- Pre-filled with 3000 (PRESETS salary default), user can clear and type their own
+- Show user's profile currency (EUR) from useAuth/profile next to input
+- Required field, must be > 0, numeric only — can't proceed without income entered
+
+### Recurring Items Step (Step 2)
+- Full checklist: all 19 PRESETS shown, grouped by category type, with item name + category badge + editable amount per row
+- Bills (4) + variable_expense (5) pre-checked by default — focuses on spending categories the wizard is about
+- Income/debt/saving/investment items unchecked by default
+- Sticky bar at top: "Remaining to allocate: Income - sum(checked) = X" — turns red when negative
+- Inline number input per item, only editable when item is checked
+
+### Review Step & Completion (Step 3)
+- Read-only summary card: income at top, grouped checked items with amounts below, total and remaining at bottom
+- "Complete" creates categories (from checked item types that don't already exist) + template items (from checked items with amounts)
+- Does NOT create first month's budget (Phase 8 handles auto-budget creation)
+- After completion: redirect to `/` (dashboard) with success toast "Template created! Your first budget will appear automatically."
+
+### Skip & State Persistence
+- "Skip" button on each step + global "Skip setup" to exit wizard entirely without creating data
+- Wizard state persisted in localStorage keyed by user_id — survives page refresh
+- On complete or skip: clear localStorage, mark profiles.setup_completed = true
+- Refreshing mid-wizard restores the wizard at the correct step
+
+### Claude's Discretion
+- Exact component decomposition (how many sub-components for the wizard)
+- Animation/transition between steps (if any)
+- Exact styling of category badges and grouping headers
+- Toast message wording variations
+- Error handling UX for failed API calls during completion
+
+</decisions>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `src/hooks/useFirstRunState.ts` — detects first-run users (isFirstRun + loading)
+- `src/hooks/useCategories.ts` — CRUD for categories (create method available)
+- `src/hooks/useTemplate.ts` — CRUD for template items (createItem method available)
+- `src/hooks/useAuth.ts` — profile access (currency, locale)
+- `src/data/presets.ts` — 19 PresetItem entries with slug, type, defaultAmount, item_tier
+- `src/components/ui/card.tsx` — Card component
+- `src/components/ui/button.tsx` — Button component
+- `src/components/ui/input.tsx` — Input component
+- `src/components/ui/badge.tsx` — Badge component (for category type indicators)
+- `src/components/ui/sonner.tsx` — Toast notifications
+- `src/i18n/en.json` + `de.json` — presets.* keys already translated
+
+### Established Patterns
+- Pages are in `src/pages/*.tsx`, routed via React Router
+- Hooks use React Query with Supabase client
+- Category types: income, bill, variable_expense, debt, saving, investment
+- UI uses Tailwind + shadcn/ui components with OKLCH pastel design tokens
+- Auth-protected routes via layout wrapper
+
+### Integration Points
+- Router: Add `/setup` route, redirect logic in dashboard or layout
+- `useFirstRunState()` — gate for redirect (check !loading && isFirstRun)
+- `useCategories().create` — create categories on wizard completion
+- `useTemplate().createItem` — create template items on wizard completion
+- `profiles.setup_completed` — mark true on completion/skip via Supabase update
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- Pre-filled common items come from the existing PRESETS array (19 items, already i18n'd)
+- The "remaining to allocate" balance = income entered in step 1 minus sum of checked item amounts in step 2
+- Wizard must not create duplicate categories if user already has some (edge case: user skipped wizard, manually created categories, then somehow re-enters wizard)
+- Phase 6 decisions: round EUR amounts, backfill existing users to setup_completed=true (they never see wizard)
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+None — discussion stayed within phase scope.

+import { Label } from "@/components/ui/label"
+import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card"
+```
+
+**Page layout pattern** (lines 34-36):

+// Standalone centered card outside AppLayout -- same pattern as LoginPage
+return (
+  <div className="flex min-h-screen items-center justify-center bg-muted/60 p-4">
+    <Card className="w-full max-w-sm border-t-4 border-t-primary shadow-lg">
+```
+
+**Async action with loading state** (lines 20-31):
+```typescript
+const [loading, setLoading] = useState(false)
+
+async function handleSubmit(e: React.FormEvent) {
+  e.preventDefault()
+  setError("")

+
+**Key adaptation:** SetupPage uses `max-w-2xl` (not `max-w-sm`) per CONTEXT decision. It manages multi-step state internally with useState + localStorage sync.

+
+**New route insertion point** -- after public routes, before AppLayout route:
+```typescript
+<Route path="/setup" element={<ProtectedRoute><SetupPage /></ProtectedRoute>} />
+```
+
+---
+
+### `src/pages/DashboardPage.tsx` (modify - add first-run redirect)
+
+**Pattern to add** (at top of DashboardPage component, before existing logic):
+```typescript
+// Source: useFirstRunState hook (src/hooks/useFirstRunState.ts)
+import { useFirstRunState } from "@/hooks/useFirstRunState"
+import { Navigate } from "react-router-dom"
+
+// Inside component body, early return:

+if (firstRunLoading) return <DashboardSkeleton />
+if (isFirstRun) return <Navigate to="/setup" replace />

+
+## Shared Patterns
+
+### Toast Notifications
+**Source:** `src/pages/SettingsPage.tsx` lines 4, 56-59
+**Apply to:** SetupPage (on completion and on error)
+```typescript
+import { toast } from "sonner"
+
+// Success:
+toast.success(t("settings.saved"))
+// Error:
+toast.error(t("common.error"))
+```
+
+### Supabase Profile Update
+**Source:** `src/pages/SettingsPage.tsx` lines 44-62
+**Apply to:** SetupPage (marking setup_completed = true)
+```typescript
+import { supabase } from "@/lib/supabase"
+
+const { error } = await supabase
+  .from("profiles")
+  .update({ setup_completed: true })
+  .eq("id", user.id)
+```
+
+### useCategories Mutation
+**Source:** `src/hooks/useCategories.ts` lines 21-38
+**Apply to:** SetupPage completion logic
+```typescript
+const { create } = useCategories()
+
+// Usage: create.mutateAsync({ name, type })
+const cat = await create.mutateAsync({ name: t(`categories.types.${type}`), type })
+// Returns Category with .id for linking template items
+```
+
+### React Query Invalidation After Completion
+**Source:** `src/hooks/useCategories.ts` line 37
+**Apply to:** SetupPage (prevent redirect loop after completion)
+```typescript
+import { useQueryClient } from "@tanstack/react-query"
+
+const queryClient = useQueryClient()
+// After creating categories + template items:
+await queryClient.invalidateQueries({ queryKey: ["categories"] })
+await queryClient.invalidateQueries({ queryKey: ["template-items"] })
+```
+
+### i18n Translation Pattern
+**Source:** `src/pages/LoginPage.tsx` lines 3, 12, 39
+**Apply to:** All setup components
+```typescript
+import { useTranslation } from "react-i18next"
+const { t } = useTranslation()
+// Usage: t("setup.stepTitle") or t(`presets.${type}.${slug}`) for preset names
+```
+
+### PRESETS Data Access
+**Source:** `src/data/presets.ts`
+**Apply to:** RecurringItemsStep, ReviewStep, SetupPage state initialization
+```typescript
+import { PRESETS } from "@/data/presets"
+// Group by type:
+const grouped = Object.groupBy(PRESETS, (p) => p.type)
+// Or filter: PRESETS.filter(p => p.type === "bill")
+```

+# Phase 7: Setup Wizard - Research
+
+**Researched:** 2026-04-20
+**Domain:** React multi-step wizard UI with localStorage persistence, Supabase writes
+**Confidence:** HIGH
+
+## Summary
+
+Phase 7 builds a 3-step setup wizard that guides first-run users through budget template creation. The phase is primarily a frontend UI task: no new DB schema changes are needed (Phase 6 delivered `setup_completed`, presets, and `useFirstRunState`). The wizard must render a new `/setup` route outside the AppLayout (standalone page like login/register), persist state to localStorage, and on completion create categories + template items via existing hooks.
+
+The codebase already provides every data layer primitive needed: `useFirstRunState` for redirect gating, `useCategories().create` for category creation, `useTemplate().createItem` for template item creation, `PRESETS` array with 19 items, and full i18n keys for preset names. The work is purely component authoring, routing, and orchestration.
+
+**Primary recommendation:** Build the wizard as a standalone page component with internal step state management using React useState + localStorage sync. No additional libraries needed -- the existing stack (React 19, React Router 7, shadcn/ui, Tailwind, React Query, Supabase) handles everything.
+
+<user_constraints>
+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+- Numbered horizontal stepper (1-2-3 bar at top) -- minimal, clear progress indicator
+- Centered card layout (max-w-2xl) on clean background -- consistent with auth pages
+- Next/Back buttons at bottom + step indicator is clickable for going back
+- Single "monthly net income" number input pre-filled with 3000, required > 0
+- Full checklist: all 19 PRESETS shown, grouped by category type, with editable amounts
+- Bills (4) + variable_expense (5) pre-checked by default
+- Sticky bar: "Remaining to allocate: Income - sum(checked) = X" -- turns red when negative
+- Read-only review step with grouped summary
+- "Complete" creates categories + template items. Does NOT create first month's budget.
+- After completion: redirect to `/` with success toast
+- "Skip" on each step + global "Skip setup" to exit entirely
+- localStorage keyed by user_id for persistence across refresh
+- On complete or skip: clear localStorage, mark profiles.setup_completed = true
+- No animated transitions between steps (instant swap)
+
+### Claude's Discretion
+- Exact component decomposition (how many sub-components for the wizard)
+- Animation/transition between steps (decided: none)
+- Exact styling of category badges and grouping headers
+- Toast message wording variations
+- Error handling UX for failed API calls during completion
+
+### Deferred Ideas (OUT OF SCOPE)
+None -- discussion stayed within phase scope.

+## Phase Requirements
+
+| ID | Description | Research Support |
+|----|-------------|------------------|
+| SETUP-01 | New user is guided through a 3-step wizard: income, recurring items, review | useFirstRunState hook for redirect gating, /setup route outside AppLayout |
+| SETUP-02 | User sees pre-filled common budget items with sensible default amounts (~15-20 items) | PRESETS array (19 items) with defaultAmount + i18n keys already exist |
+| SETUP-03 | User can skip any wizard step or the entire wizard | Skip Step per step + Skip setup global link, marks setup_completed=true |
+| SETUP-04 | User sees a live "remaining to allocate" balance updating as items are selected | Computed from useState: income - sum(checked items amounts), re-renders on change |
+| SETUP-05 | User's template is created from wizard selections on completion | useCategories().create + useTemplate().createItem mutations in sequence |
+</phase_requirements>
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Wizard UI & navigation | Browser / Client | -- | Pure client-side multi-step form, no SSR |
+| State persistence | Browser / Client | -- | localStorage for mid-session persistence |
+| First-run redirect | Browser / Client | -- | useFirstRunState reads cached React Query data |
+| Category + template creation | API / Backend (Supabase) | Browser / Client | Supabase handles insert; client calls via existing hooks |
+| setup_completed flag update | API / Backend (Supabase) | Browser / Client | Direct Supabase update from client |

+```
+
+### Pattern 1: Wizard State in localStorage
+**What:** Single useState object synced to localStorage on every change
+**When to use:** Multi-step forms that must survive page refresh
+**Example:**
+```typescript
+// Source: project convention + React docs
+interface WizardState {
+  currentStep: 1 | 2 | 3
+  income: number
+  selectedItems: Record<string, { checked: boolean; amount: number }>
+}
+
+const STORAGE_KEY = (userId: string) => `setup-wizard-${userId}`
+
+function useWizardState(userId: string) {
+  const [state, setState] = useState<WizardState>(() => {
+    const saved = localStorage.getItem(STORAGE_KEY(userId))
+    if (saved) return JSON.parse(saved)
+    return getDefaultState() // builds from PRESETS defaults
+  })
+
+  useEffect(() => {
+    localStorage.setItem(STORAGE_KEY(userId), JSON.stringify(state))
+  }, [state, userId])
+
+  return [state, setState] as const
+}
+```
+
+### Pattern 2: Completion Sequence (Category + Template Item Creation)
+**What:** Sequential creation of categories then template items, handling duplicates
+**When to use:** Wizard completion step
+**Example:**
+```typescript
+// Source: existing useCategories + useTemplate hooks
+async function completeWizard(
+  selectedItems: SelectedItem[],
+  income: number,
+  createCategory: MutateAsync,
+  createItem: MutateAsync,
+) {
+  // 1. Determine unique category types needed
+  const typesNeeded = [...new Set(selectedItems.map(i => i.type))]
+
+  // 2. Create categories (skip if already exist -- DB has unique constraint)
+  const categoryMap: Record<string, string> = {}
+  for (const type of typesNeeded) {
+    try {
+      const cat = await createCategory({ name: categoryLabel(type), type })
+      categoryMap[type] = cat.id
+    } catch (e) {
+      // Unique constraint violation = category exists, fetch it
+      // Handle gracefully
+    }
+  }
+
+  // 3. Create template items for each selected preset
+  for (const item of selectedItems) {
+    await createItem({
+      category_id: categoryMap[item.type],
+      item_tier: item.item_tier,
+      budgeted_amount: item.amount,
+    })
+  }
+}
+```
+
+### Pattern 3: Route Structure (Standalone Page Outside AppLayout)
+**What:** /setup route as a sibling to login/register, not nested in AppLayout
+**When to use:** Wizard must be full-screen without sidebar nav
+**Example:**
+```typescript
+// Source: existing App.tsx routing pattern
+<Routes>
+  {/* Public routes */}
+  <Route path="/login" element={<PublicRoute><LoginPage /></PublicRoute>} />
+  <Route path="/register" element={<PublicRoute><RegisterPage /></PublicRoute>} />
+
+  {/* Setup wizard -- protected but outside AppLayout */}
+  <Route path="/setup" element={<ProtectedRoute><SetupPage /></ProtectedRoute>} />
+
+  {/* Main app layout */}
+  <Route element={<ProtectedRoute><AppLayout /></ProtectedRoute>}>
+    <Route index element={<DashboardPage />} />
+    ...
+  </Route>
+</Routes>
+```
+
+### Anti-Patterns to Avoid
+- **Nested wizard inside AppLayout:** Wizard must be standalone (no sidebar). Keep it as a separate protected route.
+- **Creating template without categories first:** Template items require `category_id` -- categories must be created first in completion flow.
+- **Using mutateAsync without error handling:** Each Supabase insert can fail. Wrap in try/catch, show partial-error toast if some items fail.
+- **Reading profile.setup_completed for redirect:** Use `useFirstRunState` (checks categories/template data), not setup_completed flag. The flag is set on completion, not read for gating.
+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Checkbox UI | Custom div with click handlers | shadcn Checkbox (Radix) | Keyboard accessibility, aria states, focus ring |
+| Toast notifications | Custom alert/banner | sonner (already integrated) | Consistent with app, auto-dismiss, queue |
+| Number formatting | Manual toFixed/locale | Intl.NumberFormat with profile currency | Handles EUR/USD/CHF, locale-aware separators |
+| i18n key resolution | String concatenation | `t(\`presets.${type}.${slug}\`)` | Already set up in en.json/de.json |
+
+**Key insight:** Every UI primitive and data operation is already available in the project. This phase is purely about composition and orchestration.
+
+## Common Pitfalls
+
+### Pitfall 1: Redirect Loop on Dashboard
+**What goes wrong:** User completes wizard, lands on dashboard, `useFirstRunState` still returns `isFirstRun=true` because React Query cache is stale.
+**Why it happens:** Categories/template items just created but query cache not invalidated yet.
+**How to avoid:** After completion, invalidate both `["categories"]` and `["template-items"]` query keys before redirecting. Or use `setup_completed` flag for the redirect condition (check profiles table).
+**Warning signs:** User bounces between dashboard and /setup infinitely.
+
+### Pitfall 2: Category Name Collision on Completion
+**What goes wrong:** User already has a "Bills" category (edge case: skipped wizard, created manually, re-enters). DB unique constraint rejects the insert.
+**Why it happens:** Phase 6 added `UNIQUE(user_id, name)` constraint on categories.
+**How to avoid:** Use upsert or catch constraint violation errors and fetch existing category ID instead. The completion logic must handle "category already exists" gracefully.
+**Warning signs:** Wizard completion fails silently or shows generic error.
+
+### Pitfall 3: localStorage Orphan After Logout
+**What goes wrong:** User starts wizard, logs out, different user logs in -- sees previous user's wizard state.
+**Why it happens:** localStorage key must include user_id.
+**How to avoid:** Key is `setup-wizard-${userId}` (already specified in CONTEXT). Always validate userId matches on load.
+**Warning signs:** Wrong income/selections appearing for a different user.
+
+### Pitfall 4: Race Condition in Completion
+**What goes wrong:** User double-clicks "Complete Setup" and creates duplicate template items.
+**Why it happens:** Button not disabled during async operation.
+**How to avoid:** Disable Complete button immediately on click, show spinner. Use a `completing` state flag.
+**Warning signs:** Duplicate rows in template_items table.
+
+### Pitfall 5: useTemplate() Needs Template to Exist Before createItem
+**What goes wrong:** `createItem` throws "Template not loaded" because `templateId` is undefined.
+**Why it happens:** `useTemplate()` auto-creates a template row on first query, but the query must complete before `createItem` works.
+**How to avoid:** Ensure `useTemplate()` is called early in the wizard (mount time) so the template row exists by completion time. Or call `getOrCreateTemplate()` directly in the completion flow.
+**Warning signs:** "Template not loaded" error on wizard completion.
+
+## Code Examples
+
+### Redirect Logic in Dashboard (or AppLayout)
+```typescript
+// Source: existing useFirstRunState pattern + CONTEXT decisions
+import { useFirstRunState } from "@/hooks/useFirstRunState"
+import { Navigate } from "react-router-dom"
+
+// Inside DashboardPage or a redirect wrapper:
+const { isFirstRun, loading } = useFirstRunState()
+if (loading) return <Skeleton /> // or null
+if (isFirstRun) return <Navigate to="/setup" replace />
+```
+
+### Updating setup_completed on Skip/Complete
+```typescript

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Multi-page wizard with URL-per-step | Single-page with internal state | Standard for SPA wizards | Simpler routing, better state control |
+| Form library (react-hook-form) for wizards | useState for simple forms | When forms have < 5 fields | Less boilerplate for simple cases |
+| Redux/Zustand for wizard state | localStorage + useState | For isolated flows | No global store pollution |
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | shadcn checkbox installs via `npx shadcn@latest add checkbox` | Standard Stack | Low -- standard shadcn CLI pattern, easily correctable |
+| A2 | Category names for auto-creation should use i18n labels (e.g., t("categories.types.bill")) | Patterns | Medium -- if hardcoded English names used, DE users get English category names |
+
+## Open Questions
+
+1. **Category naming on creation**
+   - What we know: Categories need a `name` field. Presets are grouped by `type`.
+   - What's unclear: Should each preset create its own category (19 categories) or one category per type (6 categories)?
+   - Recommendation: One category per type (6 max). The CONTEXT says "Create categories (from checked item types that don't already exist)" -- this confirms one-per-type. Multiple template items share the same category.
+
+2. **Where to place the first-run redirect**
+   - What we know: `useFirstRunState` returns `isFirstRun` based on categories/template data.
+   - What's unclear: Should redirect live in DashboardPage, AppLayout, or a wrapper component?
+   - Recommendation: Place in DashboardPage (the index route) since that's where first-run users land. Avoids affecting other routes.
+
+## Validation Architecture
+
+### Test Framework
+| Property | Value |
+|----------|-------|
+| Framework | None detected (no test config or test files found) |
+| Config file | none -- Wave 0 must create |
+| Quick run command | N/A |
+| Full suite command | N/A |
+
+### Phase Requirements to Test Map
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| SETUP-01 | First-run user sees wizard, 3 steps | manual | Manual browser test | N/A |
+| SETUP-02 | 19 pre-filled items with amounts | manual | Visual verification | N/A |
+| SETUP-03 | Skip step/wizard works | manual | Click through wizard | N/A |
+| SETUP-04 | Remaining balance updates live | manual | Check/uncheck items | N/A |
+| SETUP-05 | Template created from selections | manual | Complete wizard, check /template | N/A |
+
+### Wave 0 Gaps
+No test framework exists in this project. All verification is manual/visual. This is acceptable per the project's established pattern -- no test files exist anywhere in `src/`.
+
+## Security Domain
+
+### Applicable ASVS Categories
+
+| ASVS Category | Applies | Standard Control |
+|---------------|---------|-----------------|
+| V2 Authentication | no | Already handled by ProtectedRoute |
+| V3 Session Management | no | Supabase session management |
+| V4 Access Control | yes | RLS policies on categories/template_items (already in place) |
+| V5 Input Validation | yes | Income > 0 validation, amounts must be positive numbers |
+| V6 Cryptography | no | No crypto needed |
+
+### Known Threat Patterns for This Phase
+
+| Pattern | STRIDE | Standard Mitigation |
+|---------|--------|---------------------|
+| localStorage tampering | Tampering | Validate localStorage data shape on load; sanitize numbers |
+| Mass insert abuse (spam completion) | Denial of Service | setup_completed flag prevents re-entry; RLS limits to own user |
+| XSS via preset slug injection | Spoofing | Presets are hardcoded in source, not user-input; i18n keys are safe |

+# Phase 7 — UI Design Contract
+
+> Visual and interaction contract for the 3-step setup wizard. Generated by gsd-ui-researcher, verified by gsd-ui-checker.
+
+---
+
+## Design System
+
+| Property | Value |
+|----------|-------|
+| Tool | shadcn (new-york style) |
+| Preset | new-york, baseColor neutral, cssVariables true |
+| Component library | Radix UI (via shadcn/ui) |
+| Icon library | Lucide |
+| Font | Inter, ui-sans-serif, system-ui, sans-serif |
+
+---
+
+## Spacing Scale
+
+Declared values (must be multiples of 4):
+
+| Token | Value | Usage |
+|-------|-------|-------|
+| xs | 4px | Icon gaps, inline padding |
+| sm | 8px | Compact element spacing, checkbox-to-label gap |
+| md | 16px | Default element spacing, card internal padding |
+| lg | 24px | Section padding, stepper step gaps |
+| xl | 32px | Layout gaps, card content vertical spacing |
+| 2xl | 48px | Step card top/bottom padding |
+| 3xl | 64px | Page-level vertical centering offset |
+
+Exceptions: Sticky allocation bar uses 12px vertical padding (py-3) for visual compactness within the card.
+
+---
+
+## Typography
+
+| Role | Size | Weight | Line Height |
+|------|------|--------|-------------|
+| Body | 14px | 400 (regular) | 1.5 |
+| Label | 14px | 600 (semibold) | 1.4 |
+| Heading | 20px | 600 (semibold) | 1.2 |
+| Display | 28px | 600 (semibold) | 1.2 |
+
+Only two weights are used: 400 (regular) for body text and 600 (semibold) for labels, headings, and display. No medium (500) weight exists in this contract.
+
+Usage in wizard:
+- **Display (28px/600):** Wizard page title "Set up your budget" (step 1 heading area)
+- **Heading (20px/600):** Step card titles ("Monthly Income", "Recurring Items", "Review")
+- **Label (14px/600):** Category group headers (e.g., "Bills", "Variable Expenses"), stepper step labels, "Remaining to allocate" label, form field labels
+- **Body (14px/400):** Preset item names, amounts, helper text, step descriptions
+
+---
+
+## Color
+
+| Role | Value | Usage |
+|------|-------|-------|
+| Dominant (60%) | `oklch(0.98 0.01 260)` (--background) | Page background behind wizard card |
+| Secondary (30%) | `oklch(1 0 0)` (--card) | Wizard card surface, review summary card |
+| Accent (10%) | `oklch(0.55 0.15 260)` (--primary) | Active stepper step indicator, primary CTA buttons, step number circles (active) |
+| Destructive | `oklch(0.6 0.2 25)` (--destructive) | Negative "remaining to allocate" text, validation error text |
+
+**Focal point:** The primary CTA button ("Next Step" / "Complete Setup") in the bottom-right of the card is the single focal point on every step. It is the only large accent-colored element in the viewport, drawing the eye to the next action.
+
+Accent reserved for:
+- Active step circle in the stepper (filled primary background)
+- "Next Step" and "Complete Setup" primary buttons
+- Income input focus ring
+- Completed step checkmark icon color
+
+Additional semantic colors used (existing tokens):
+- `--color-income` (`oklch(0.55 0.17 155)`): Income category group header dot and badge
+- `--color-bill` (`oklch(0.55 0.17 25)`): Bill category group header dot and badge
+- `--color-variable-expense` (`oklch(0.58 0.16 50)`): Variable expense category group header dot and badge
+- `--color-debt` (`oklch(0.52 0.18 355)`): Debt category group header dot and badge
+- `--color-saving` (`oklch(0.55 0.16 220)`): Saving category group header dot and badge
+- `--color-investment` (`oklch(0.55 0.16 285)`): Investment category group header dot and badge
+- `--color-on-budget` (`oklch(0.50 0.17 155)`): Positive "remaining to allocate" text (green)

+  
+  - If no items selected: show muted message "No items selected. You can add items to your template later."
+```
+
+### Skip Controls
+
+```
+Per-step skip: Ghost button "Skip Step" in the bottom-left nav area
+  - Advances to next step without saving current step data
+  - On step 3 skip: same as "Skip setup" (exits wizard)
+
+Global skip: "Skip setup" link/button
+  - Position: below the card, centered, text-sm text-muted-foreground underline
+  - Margin top: 16px below card
+  - Action: clears localStorage, sets profiles.setup_completed = true, redirects to dashboard
+  - No confirmation dialog (non-destructive — user can still manually set up template)
+```
+
+---
+
+## Interaction Contract
+
+### Step Navigation
+
+| Action | Behavior |
+|--------|----------|
+| Click "Next Step" (step 1) | Validate income > 0. If valid, transition to step 2. If invalid, show inline error. |
+| Click "Next Step" (step 2) | No validation required (0 items selected is valid). Transition to step 3. |
+| Click "Go Back" | Return to previous step. Preserve all entered data. |
+| Click stepper circle (completed) | Navigate to that step. Preserve all data. |
+| Click stepper circle (future) | No action. Cursor: default. |
+| Click "Complete Setup" (step 3) | Create categories + template items via API. On success: clear localStorage, set setup_completed=true, redirect to dashboard with toast. |
+| Click "Skip Step" (per-step) | Advance to next step without current step data. Step 1 skip: income stays at default or last entered value. Step 2 skip: uncheck all items. |
+| Click "Skip setup" (global) | Exit wizard entirely. Clear localStorage. Mark setup_completed=true. Redirect to dashboard. No toast. |
+| Page refresh mid-wizard | Restore wizard at the same step with all entered data from localStorage. |
+
+### State Persistence (localStorage)
+
+```
+Key: `setup-wizard-${userId}`
+Value: JSON object
+{
+  currentStep: 1 | 2 | 3,
+  income: number,
+  selectedItems: Record<string, { checked: boolean, amount: number }>,
+  // keyed by preset slug
+}
+Cleared on: wizard completion OR skip setup
+```
+
+### Loading & Error States
+
+| State | Behavior |
+|-------|----------|
+| Wizard loading (useFirstRunState pending) | Show centered Skeleton matching card dimensions (max-w-2xl, h-64) |
+| Completion API in progress | "Complete Setup" button shows spinner + disabled. Go Back/Skip Step also disabled. |
+| Completion API failure | Toast (sonner, variant destructive): "Could not save your template. Please try again." Button re-enables. Data preserved. |
+| Partial completion failure | If categories created but template items fail: toast with "Some items could not be saved. Check your template page." Redirect to dashboard anyway. |
+
+### Transitions Between Steps
+
+No animated transitions between steps. Instant swap of step content within the card. The stepper bar updates synchronously.
+
+---
+
+## Copywriting Contract
+
+All copy must have i18n keys in both `en.json` and `de.json`. Keys live under a `setup` namespace.
+
+| Element | EN Copy | i18n Key |
+|---------|---------|----------|
+| Page title (step 1) | Set up your budget | `setup.title` |
+| Step 1 title | Monthly Income | `setup.step1.title` |
+| Step 1 description | How much do you earn each month? | `setup.step1.description` |
+| Step 1 label | Monthly net income | `setup.step1.incomeLabel` |
+| Step 1 helper | Enter your total monthly take-home pay | `setup.step1.helper` |
+| Step 1 validation | Please enter a positive income amount | `setup.step1.validation` |
+| Step 2 title | Recurring Items | `setup.step2.title` |
+| Step 2 description | Select your regular monthly expenses | `setup.step2.description` |
+| Allocation bar label | Remaining to allocate | `setup.step2.remaining` |
+| Step 3 title | Review | `setup.step3.title` |
+| Step 3 description | Confirm your budget template | `setup.step3.description` |
+| Step 3 income label | Monthly income | `setup.step3.incomeLabel` |
+| Step 3 total label | Total expenses | `setup.step3.totalLabel` |
+| Step 3 remaining label | Remaining | `setup.step3.remainingLabel` |
+| Step 3 empty | No items selected. You can add items to your template later. | `setup.step3.empty` |
+| Stepper labels | Income / Items / Review | `setup.steps.1` / `setup.steps.2` / `setup.steps.3` |
+| Next button | Next Step | `setup.next` |
+| Back button | Go Back | `setup.back` |
+| Skip button | Skip Step | `setup.skip` |
+| Skip setup link | Skip setup | `setup.skipSetup` |
+| Complete button | Complete Setup | `setup.complete` |
+| Success toast | Template created! Your first budget will appear automatically. | `setup.toast.success` |
+| Error toast | Could not save your template. Please try again. | `setup.toast.error` |
+| Partial error toast | Some items could not be saved. Check your template page. | `setup.toast.partialError` |
+

+
+## Registry Safety
+
+| Registry | Blocks Used | Safety Gate |
+|----------|-------------|-------------|
+| shadcn official | checkbox | not required |
+
+No third-party registries declared.
+
+---
+
+## Accessibility Contract
+
+| Concern | Implementation |
+|---------|----------------|
+| Stepper semantics | `role="navigation"` with `aria-label="Setup progress"`. Each step: `role="tab"`, `aria-selected` for active, `aria-disabled` for future. |
+| Step content | `role="tabpanel"` with `aria-labelledby` pointing to the active step tab. |
+| Checkbox group | Each category group is a `fieldset` with `legend` (visually styled as CategoryGroupHeader). |
+| Income input | `aria-describedby` pointing to helper text and validation error (when shown). |
+| Allocation bar | `aria-live="polite"` so screen readers announce remaining amount changes. |
+| Skip links | Visible, keyboard-focusable. Not hidden behind hover. |
+| Focus management | On step transition, focus moves to the step card heading. |
+
+---
+
+## Responsive Behavior
+
+| Breakpoint | Behavior |
+|------------|----------|
+| >= 768px (md) | max-w-2xl card centered, stepper horizontal with labels below circles |
+| < 768px (sm) | Card becomes full-width (mx-4). Stepper collapses: show circles only, hide step labels. Amount inputs remain w-24. |
+| < 480px (xs) | PresetItemRow: badge hidden, amount input w-20. Category group headers wrap naturally. |

+|---|-------|--------|----------|
+| 1 | A new user is automatically redirected to /setup on first login and sees a 3-step wizard | VERIFIED | DashboardPage.tsx:293 `if (isFirstRun) return <Navigate to="/setup" replace />`, SetupPage renders WizardStepper with 3 steps |
+| 2 | The recurring items step shows ~15-20 pre-filled common items with editable default amounts | VERIFIED | RecurringItemsStep imports PRESETS (20 items counted in presets.ts), renders each with PresetItemRow including editable amount Input |

+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| (none) | - | - | - | No TODOs, FIXMEs, placeholders, or stubs found in any wizard file |
+
+### Human Verification Required
+
+### 1. Full Wizard Flow (End-to-End)
+
+**Test:** Create a new user (zero categories/template items), log in, verify auto-redirect to /setup and complete the 3-step wizard flow end-to-end
+**Expected:** Step 1 shows income pre-filled at 3000 with EUR suffix. Step 2 shows grouped presets with bills+variable_expense pre-checked. AllocationBar updates live. Step 3 shows read-only summary. Complete creates categories + template items, redirects to dashboard with success toast.
+**Why human:** Full user flow spanning multiple pages, Supabase writes, React Query cache invalidation, redirect behavior, and toast notifications cannot be verified statically
+
+### 2. Skip Flow
+
+**Test:** Fresh user clicks "Skip setup" from step 1
+**Expected:** Redirects to dashboard with no data created, setup_completed=true in profiles table
+**Why human:** Requires Supabase interaction and verifying database state after redirect
+
+### 3. localStorage Persistence
+
+**Test:** Start wizard, advance to step 2, refresh page
+**Expected:** Wizard resumes at step 2 with previously entered income preserved
+**Why human:** Browser localStorage behavior cannot be verified without running the app
+
+### 4. No Redirect Loop After Completion
+
+**Test:** After completing wizard, verify dashboard loads normally without re-redirecting to /setup
+**Expected:** Dashboard renders correctly, useFirstRunState returns isFirstRun=false
+**Why human:** Requires React Query cache freshness and useFirstRunState reading updated data after completion
+
+### Gaps Summary
+
+No code-level gaps found. All artifacts exist, are substantive (no stubs or placeholders), are properly wired, and TypeScript compiles cleanly. The implementation covers all 5 ROADMAP success criteria and all 5 requirement IDs (SETUP-01 through SETUP-05). Human verification is needed to confirm the runtime behavior (Supabase writes, redirect flows, localStorage persistence).

+
+## v2.0 Architecture Changes
+
+### 1. First-Run Detection and Wizard Routing
+
+**Problem:** New users land on Dashboard with empty categories, no template, no budget. The blank state offers no guidance.
+
+**Solution:** A `useFirstRunState` hook detects first-run status. A `WizardRoute` guard in `App.tsx` redirects first-run users to `/setup` (a dedicated wizard page) before they can reach any other protected route.
+
+**New hook — `src/hooks/useFirstRunState.ts`:**
+
+```typescript
+// Returns { needsSetup: boolean, loading: boolean }
+// needsSetup = true when: categories.length === 0 OR template_items.length === 0
+// Uses existing useCategories() and useTemplate() — no new DB queries
+export function useFirstRunState(): { needsSetup: boolean; loading: boolean }
+```
+
+**Route change — `src/App.tsx`:**
+
+```
+// Add /setup route
+// Add WizardRoute guard that wraps the existing ProtectedRoute subtree:
+//   if needsSetup && path !== "/setup" → redirect to /setup
+//   if !needsSetup && path === "/setup" → redirect to /
+
+<Route path="/setup" element={<ProtectedRoute><SetupWizardPage /></ProtectedRoute>} />
+```
+
+**Wizard state — local `useState` only in `SetupWizardPage`:**
+
+```typescript
+type WizardState = {
+  step: 1 | 2 | 3
+  selectedPresets: string[]        // preset IDs chosen in step 1
+  amounts: Record<string, number>  // presetId → budgeted amount (step 2)
+}
+```
+
+Wizard state is ephemeral. It lives in the page component and is discarded on unmount. No context, no global store.
+
+**Completion flow:** `handleFinish()` in `SetupWizardPage` runs:
+1. `useCategories().create` × N (create one category row per selected preset)
+2. `useTemplate().createItem` × N (create template items, each linked to the new categories)
+3. `navigate("/")` — DashboardPage loads, `useFirstRunState` returns `needsSetup=false`
+
+**Preset data — `src/data/presets.ts`:** Static array of common budget items (rent, salary, groceries, car insurance, etc.) with suggested amounts and category types. No DB table needed — this is compile-time data.
+
+**No new DB migration.** Wizard writes to existing `categories` and `template_items` tables.
+
+**New files:**
+- `src/hooks/useFirstRunState.ts`
+- `src/pages/SetupWizardPage.tsx`
+- `src/components/wizard/WizardStep.tsx`
+- `src/components/wizard/CategoryDefaults.tsx`
+- `src/components/wizard/TemplateDefaults.tsx`
+- `src/data/presets.ts`
+
+**Modified files:**
+- `src/App.tsx` — add `/setup` route + WizardRoute guard
+
+---
+
+### 2. Auto-Budget Creation on Month Visit
+
+**Problem:** Visiting the dashboard for a new month shows an empty state with two manual buttons ("Create Budget", "Generate from Template"). This friction contradicts the "just works" goal.
+
+**Solution:** Auto-trigger `generateFromTemplate` inside a `useEffect` in `DashboardPage` when no budget exists for the current month and the user's template has items.
+
+**Integration point — `src/pages/DashboardPage.tsx`:**
+
+Add `useTemplate()` call alongside the existing `useBudgets()` call. Add a `useEffect` with these guards:
+
+```typescript
+const { items: templateItems } = useTemplate()
+const hasTemplateItems = templateItems.length > 0
+const isCurrentMonth = month === currentMonth   // currentMonth from useMonthParam baseline
+const attempted = useRef(false)
+
+useEffect(() => {
+  if (
+    !loading &&
+    !currentBudget &&
+    hasTemplateItems &&
+    isCurrentMonth &&
+    !attempted.current &&
+    !generateFromTemplate.isPending
+  ) {
+    attempted.current = true
+    generateFromTemplate.mutate({ month: parsedMonth, year: parsedYear, currency })
+  }
+}, [loading, currentBudget, hasTemplateItems, isCurrentMonth])
+```
+
+**Currency source:** The `generateFromTemplate` mutation currently accepts `currency` as a param. Pull the user's preferred currency from the profile via a `useProfile` hook or extend `useAuth` to expose it. If `useProfile` is not yet implemented, fall back to reading from the most recent budget's `currency` field, or default to the settings page value.
+
+**No new API endpoint.** The `generateFromTemplate` mutation in `useBudgets.ts` already handles the full create + seed flow server-side. This is a pure frontend trigger change.
+
+**Edge cases handled by the guards:**
+- Template has 0 items → `hasTemplateItems=false` → skip auto-create, show prompt to configure template
+- Budget already exists → `!currentBudget=false` → skip
+- Past/future month navigation → `isCurrentMonth=false` → skip (only auto-create for today's month)
+- Multiple renders before mutation completes → `attempted` ref prevents double-fire
+
+**Modified files:**
+- `src/pages/DashboardPage.tsx` — add useTemplate(), useEffect trigger, currency source
+
+---
+
+### 3. Inline Add-from-Category-Library (Replaces QuickAdd Page)
+
+**Problem:** QuickAdd is a separate nav page (`/quick-add`), a separate table (`quick_add_items`), and a Popover on the Dashboard. Three disconnected surfaces for one concept. The mental model is unclear.
+
+**Solution:** Replace the QuickAdd Popover with an `AddOneOffSheet` component (a shadcn Sheet/side panel) available directly on BudgetDetailPage and Dashboard. It shows the user's category list grouped by type. The user picks a category, enters an amount, and a `one_off` budget item is created. The `quick_add_items` table remains intact but is removed from the primary workflow.
+
+**New component — `src/components/budget/AddOneOffSheet.tsx`:**
+
+```typescript
+interface AddOneOffSheetProps {
+  budgetId: string
+  open: boolean
+  onOpenChange: (open: boolean) => void
+}
+// Uses: useCategories() + useBudgets().createItem
+// On save: createItem.mutate({ budgetId, category_id, budgeted_amount, actual_amount, notes, item_tier: "one_off" })
+```
+
+This replaces `QuickAddPicker.tsx` at both call sites. The existing `useBudgets().createItem` mutation is unchanged — it already inserts `item_tier: "one_off"` budget items.
+
+**QuickAdd page fate:** Remove from `AppLayout.tsx` nav items array. Keep the route and page file in place (backwards compat, existing data). Do NOT drop the `quick_add_items` table or `useQuickAdd` hook.
+
+**Modified files:**
+- `src/components/AppLayout.tsx` — remove QuickAdd from `navItems` array
+- `src/pages/DashboardPage.tsx` — replace `<QuickAddPicker>` with `<AddOneOffSheet>`
+- `src/pages/BudgetDetailPage.tsx` — replace `<QuickAddPicker>` with `<AddOneOffSheet>`
+
+**New files:**
+- `src/components/budget/AddOneOffSheet.tsx`
+
+**No DB migration needed.** `one_off` budget items already exist in `budget_items` with `item_tier = 'one_off'`.
+
+---
+
+### 4. Dashboard Simplification
+
+**Problem:** The current dashboard renders three chart types (donut + two bar charts) in a 3-column grid plus collapsible sections. This is dense and the charts don't clearly reflect user-entered data. v2.0 goal: "this month's budget at a glance."
+
+**Solution:** Remove the 3-column chart grid from `DashboardContent`. Keep `SummaryStrip` (3 KPI cards) and `CollapsibleSections`. The chart components stay in the codebase — they are correct — but are removed from the Dashboard layout.
+
+**Modified files:**
+- `src/pages/DashboardPage.tsx` — remove chart grid `<div>` and the three chart imports from `DashboardContent`
+
+**Dashboard data correctness:** The aggregation logic (`totalIncome`, `totalExpenses`, `budgetedIncome`, `budgetedExpenses`) is already correct in `DashboardContent`. The perceived "data not reflecting input" issue is caused by the auto-create flow not existing yet — once a budget exists and items are populated, the existing calculations are accurate. No aggregation logic changes needed.
+
+**Empty state after removing charts:** The removed chart area frees vertical space. Collapsible sections become the primary view. The `SummaryStrip` at the top provides the quick-glance summary. Consider adding a single "at a glance" progress indicator to `SummaryStrip` to compensate for the removed chart density.
+
+---
+
+### 5. Design System Token Rework
+
+**Problem:** `--radius: 0.625rem` produces rounded corners everywhere. The palette has high chroma values that read as saturated rather than pastel.
+
+**Solution:** Lower the radius token and tune OKLCH lightness/chroma in `index.css`. All shadcn/ui components reference `--radius` via `rounded-[--radius]` — a single value change propagates everywhere.
+
+**The only changed file: `src/index.css`**
+
+Key changes:
+```css
+/* Sharp edges */
+--radius: 0.125rem;  /* was 0.625rem */
+
+/* Background: warmer, closer to pure white */
+--color-background: oklch(0.99 0.003 260);  /* was 0.98 0.005 260 */
+
+/* Softer border */
+--color-border: oklch(0.91 0.008 260);  /* was 0.88 0.01 260 */
+
+/* Category pastels: increase lightness slightly, keep chroma */
+/* e.g. --color-income-fill: oklch(0.72 0.14 155) → 0.78 0.12 155 */
+```
+
+**What does NOT change:**
+- Token names (e.g., `--color-income`, `--color-bill`) — `palette.ts` references these by name
+- Two-tier pattern (text tokens at ~0.55L, fill tokens at ~0.68–0.78L)
+- Category color identities (income=green, bill=orange-red, etc.)
+- The `@theme inline` structure
+
+**shadcn component customization:** Zero component-file changes required. Radius change propagates automatically. Color changes propagate via CSS var resolution.

+## New vs Modified File Summary
+
+### New Files
+
+| File | Purpose |
+|------|---------|
+| `src/hooks/useFirstRunState.ts` | Detect first-run: categories=0 OR template_items=0 |
+| `src/data/presets.ts` | Static preset category list with suggested amounts |
+| `src/pages/SetupWizardPage.tsx` | Multi-step first-run wizard (local state, 3 steps) |
+| `src/components/wizard/WizardStep.tsx` | Step wrapper with step indicator / progress |
+| `src/components/wizard/CategoryDefaults.tsx` | Preset category checkbox picker (step 1) |
+| `src/components/wizard/TemplateDefaults.tsx` | Amount inputs per selected preset (step 2) |
+| `src/components/budget/AddOneOffSheet.tsx` | Sheet-based one-off item adder (replaces QuickAddPicker) |
+
+### Modified Files
+
+| File | What Changes |
+|------|-------------|
+| `src/App.tsx` | Add `/setup` route; add WizardRoute guard |
+| `src/components/AppLayout.tsx` | Remove QuickAdd from `navItems` array |
+| `src/pages/DashboardPage.tsx` | Add useTemplate(); add auto-create useEffect; remove chart grid; swap AddOneOffSheet for QuickAddPicker |

+| `src/i18n/en.json` | Add wizard i18n keys; remove/rename quick-add nav key |
+| `src/i18n/de.json` | Same additions as en.json (bilingual requirement) |
+
+### Unchanged Files (confirmed)
+
+`useBudgets.ts`, `useTemplate.ts`, `useCategories.ts`, `useQuickAdd.ts`, `useAuth.ts`, `useMonthParam.ts`, `lib/types.ts`, `lib/palette.ts`, `lib/format.ts`, `lib/supabase.ts` — all hooks and library files are read-only for this milestone.
+
+---
+
+## Build Order (Dependency-Aware)
+
+Phase dependencies must be respected. Build bottom-up.
+
+**Phase 1: Design Tokens (no deps)**
+- `src/index.css` — lower `--radius`, refine OKLCH pastel values
+- Verify all 9 existing pages render correctly; no logic changes
+- Fast and reversible — do this first to establish visual baseline
+
+**Phase 2: Preset Data + First-Run Hook (no deps)**
+- `src/data/presets.ts` — static data, no imports needed
+- `src/hooks/useFirstRunState.ts` — depends on existing `useCategories` + `useTemplate`; no UI yet
+
+**Phase 3: Setup Wizard (depends on Phase 2)**
+- `src/components/wizard/WizardStep.tsx` — pure presentational
+- `src/components/wizard/CategoryDefaults.tsx` — depends on presets.ts
+- `src/components/wizard/TemplateDefaults.tsx` — depends on presets.ts
+- `src/pages/SetupWizardPage.tsx` — assembles wizard components + useFirstRunState + mutation hooks
+- `src/App.tsx` — wire `/setup` route + WizardRoute guard
+
+**Phase 4: Auto-Budget Creation (depends on Phase 3 — template must be populatable)**
+- `src/pages/DashboardPage.tsx` — add `useTemplate()` import + auto-create `useEffect`
+- Test: wizard → dashboard → budget auto-creates → SummaryStrip shows template data
+
+**Phase 5: Inline Add-One-Off + Dashboard Simplification (depends on Phase 4)**
+- `src/components/budget/AddOneOffSheet.tsx` — depends on `useCategories` + `useBudgets` (both existing)
+- `src/pages/DashboardPage.tsx` — remove chart grid; wire AddOneOffSheet
+- `src/pages/BudgetDetailPage.tsx` — wire AddOneOffSheet
+- `src/components/AppLayout.tsx` — remove QuickAdd nav item
+

+
+## Anti-Patterns to Avoid
+
+### Anti-Pattern 1: Global State for Wizard
+
+**What people do:** Store wizard state in a React context, Zustand store, or TanStack Query mutation cache.
+**Why it's wrong:** Wizard runs once, on first login. Global state persists unnecessarily and creates cleanup complexity.
+**Do this instead:** Local `useState` in `SetupWizardPage`. When the page unmounts (after `navigate("/")`), state is automatically cleaned up.
+
+### Anti-Pattern 2: Auto-Create Without Template Guard
+
+**What people do:** Trigger `generateFromTemplate` whenever `!currentBudget`, regardless of template state.
+**Why it's wrong:** If a user skips the wizard or has an empty template, an empty budget gets silently created. This is worse than the empty state — it looks like a bug, not a fresh start.
+**Do this instead:** Guard with `hasTemplateItems && isCurrentMonth`. Show a helpful CTA to configure the template if template is empty.
+
+### Anti-Pattern 3: Dropping the quick_add_items Table
+
+**What people do:** Add a migration to drop `quick_add_items` when the QuickAdd nav item is removed.
+**Why it's wrong:** Existing users have data there. The DB migration is irreversible. The table costs nothing to keep.
+**Do this instead:** Remove the nav item and surface only. Leave the table, `useQuickAdd` hook, and `/quick-add` route in place. Schedule a cleanup migration in a future milestone after confirming no users rely on it.
+
+### Anti-Pattern 4: Renaming Design Token CSS Variables
+
+**What people do:** Rename tokens during the design rework (e.g., `--color-income` → `--category-color-income`) to make the naming more semantic.
+**Why it's wrong:** `palette.ts` references token names as strings: `var(--color-income)`. All chart components use `var(--color-income-fill)`. Renaming causes silent CSS failures — no TypeScript error, no build error, just missing colors.
+**Do this instead:** Change only the VALUES of existing tokens. Add new token names only for net-new concepts.
+
+### Anti-Pattern 5: Wizard as Modal Overlay
+
+**What people do:** Show the wizard as a Dialog or Sheet over the main app layout on first load.
+**Why it's wrong:** No URL, so refresh drops the user back to the start or the main app with incomplete setup. Focus management in a full-screen modal is complex. Back button behavior is broken.
+**Do this instead:** Dedicated `/setup` route. `WizardRoute` handles redirect logic. The browser URL reflects wizard state, refresh works, and no special cleanup is needed.
+
+### Anti-Pattern 6: Adding useEffect Dependencies by Feel
+
+**What people do:** Add `generateFromTemplate` itself to the `useEffect` deps array.
+**Why it's wrong:** Mutation objects from TanStack Query are re-created on every render, causing the effect to re-run in a loop.
+**Do this instead:** Use a `useRef` guard (`attempted.current`) and gate on stable primitive values (`!loading`, `!currentBudget`, `hasTemplateItems`). Do not include the mutation object in the dependency array.
+

+
+## Supabase / DB Notes (v2.0)
+
+**No new migrations required.** All v2.0 features write to existing tables:
+
+| Feature | Writes To | Via |
+|---------|-----------|-----|
+| Wizard | `categories`, `template_items` | existing `useCategories().create`, `useTemplate().createItem` |
+| Auto-budget | `budgets`, `budget_items` | existing `useBudgets().generateFromTemplate` |
+| Inline one-off | `budget_items` | existing `useBudgets().createItem` |
+| Design tokens | — | CSS only |
+
+The `quick_add_items` table becomes read-only from the primary UI flow. No rows deleted, no schema change.
+
+---
+
+## Integration Points: New vs Existing
+
+| New Feature | Existing Hooks/Mutations Used | New Additions |
+|-------------|------------------------------|---------------|
+| First-run wizard | `useCategories().create`, `useTemplate().createItem` | `useFirstRunState`, `presets.ts`, wizard components |
+| Auto-budget creation | `useBudgets().generateFromTemplate` (already exists) | `useEffect` trigger in DashboardPage, `hasTemplateItems` guard |
+| Inline one-off add | `useBudgets().createItem` (already exists), `useCategories()` | `AddOneOffSheet` component |
+| Dashboard simplification | `useBudgetDetail`, `useMonthParam`, `SummaryStrip`, `CollapsibleSections` | Remove 3-column chart grid from DashboardContent |
+| Design tokens | All existing components consume tokens automatically | Token value adjustments in `index.css` only |

+# Feature Research
+
+**Domain:** Personal budget app — wizard-driven setup, auto-budget creation, simplified monthly tracking UX
+**Researched:** 2026-04-02
+**Confidence:** MEDIUM — grounded in competitor analysis (YNAB, Monarch, EveryDollar, Actual Budget, Quicken Simplifi, Copilot) and UX/fintech design literature. Some specifics are inferred from behavioral patterns; no first-party user testing data.
+
+---
+
+## Context
+
+This research covers v2.0 UX Simplification. The existing app already has all the data infrastructure — categories (6 types), template system, monthly budget generation, quick-add library, dashboard with charts. The problem is cognitive: too many disconnected concepts, friction in getting a budget running, and no guided experience for new users.
+
+The research question: **How do personal budget apps handle first-run wizard setup, auto-creation from template, and simplified monthly views?** What is table stakes, what differentiates, and what should be avoided?
+
+Existing features that remain and are not re-researched here:
+- Category CRUD
+- Template item management
+- Budget detail with inline editing
+- Charts (donut, bar, horizontal bar)
+- Collapsible dashboard sections
+- Settings (locale, currency)
+
+---
+
+## Feature Landscape
+
+### Table Stakes (Users Expect These)
+
+Features users assume exist. Missing these = product feels incomplete or broken.
+
+| Feature | Why Expected | Complexity | Notes |
+|---------|--------------|------------|-------|
+| Wizard-style first-run setup | Every modern app (YNAB, EveryDollar, Monarch) guides new users through initial setup — no blank-slate drop. Blank-state is a known retention killer for budget apps. | MEDIUM | Multi-step flow: income → recurring items → review. Must be skippable per step. |
+| Pre-filled category items with common defaults | Users expect "rent," "groceries," "car insurance" to already be there — not to type everything from scratch. YNAB's Beginner Template and Quicken Simplifi both provide starter category lists. | LOW | Pre-seed the wizard with a curated list of ~15-20 common items grouped by type. User selects/deselects, edits amounts. |
+| Auto-created budget on first month visit | After setup, users expect a budget to exist for the current month without a separate "generate budget" step. The manual trigger pattern is a v1-era pattern that creates friction. Quicken Simplifi does this with its Spending Plan. | MEDIUM | Trigger auto-generation server-side when a user visits the current month and no budget exists. |
+| Ability to skip setup and start minimal | Power users and returning users want to start blank or skip ahead. Forcing everyone through a wizard is patronizing. | LOW | Each wizard step needs a "Skip" option. Entire wizard skippable via "I'll set this up later." |
+| Inline add-from-library on the budget view | Users expect to add a one-off expense from their familiar item list without navigating away. The current separate Quick-Add page is a disconnect. Spendee and Actual Budget surface this inline. | MEDIUM | Replace Quick-Add page with an inline panel/sheet triggered from the budget view. Category + item picker, amount field, confirm. |
+| Monthly budget shows budgeted vs actual, grouped | The core interaction loop: open budget, see what's in each category, enter actuals. Every app (YNAB, EveryDollar, Actual Budget) organizes this as grouped rows with a budgeted amount and an actuals field. | LOW | Already exists in the current BudgetDetailPage. Table stakes means this must work correctly and clearly — not changed, just verified. |
+| Dashboard = this month's budget at a glance | Users want to open the app and immediately know their status: income, spending, balance. Not a chart gallery. Monarch and Copilot both lead with a "current month" summary card. | LOW | Dashboard must surface current month's data prominently — summary cards first, then detail. Already partially true; needs data correctness fix. |
+| Empty state with clear call to action | If no template is set up, the app must explain what to do — not just show a blank page. "Set up your budget template" with a single action button. | LOW | Applies to: empty template page, empty budget view, empty dashboard. |
+
+### Differentiators (Competitive Advantage)
+
+Features that set the product apart. Not required, but valued.
+
+| Feature | Value Proposition | Complexity | Notes |
+|---------|-------------------|------------|-------|
+| Smart amount suggestions during wizard setup | Rather than blank amount fields, prefill with sensible defaults (e.g., $1,500 for rent, $400 for groceries) that users can override. Reduces the "I don't know what to put here" paralysis. Most apps leave this blank. | LOW | Can be static defaults (not AI). Store suggested amounts per item type in a constant/config. User edits freely. |
+| "Start from your income" wizard framing | Frame setup as: "First, how much do you earn each month?" then "Here are common expenses people like you track." Income-first anchoring mirrors zero-based budgeting mental model (YNAB's core concept) and makes subsequent amounts feel grounded. | LOW | First wizard step = income amount. Subsequent steps show remaining balance updating as items are added — "you have $X left to allocate." |
+| Running balance display during wizard | As the user adds items in the wizard, show "Remaining to allocate: $X" updating live. Makes it immediately obvious if they're over-allocating. This is YNAB's core interaction loop, applied to setup. | LOW | Derived from: income total minus sum of bill/expense/debt/saving/investment items. Frontend computation only. |
+| Persistent sidebar "this month" widget on dashboard | A small always-visible card showing remaining balance for the month, top 2-3 categories near limit, and a "View full budget" link. Eliminates the need to navigate away to check status. Copilot uses this pattern. | MEDIUM | Requires current month budget query always running. Can be a sticky sidebar panel on the dashboard page rather than a global element. |
+| Auto-create silently, notify only on first creation | First-time users see a brief notification "Your March budget was created from your template." Subsequent months: silently created, no notification. This is the right default — zero friction for users who've set up their template. | LOW | Backend: check if budget for current month exists on page load; create if not. Frontend: show a toast only if a new budget was just created. |
+| Template edit directly accessible from monthly view | If a user wants to permanently change a recurring item (e.g., rent went up), they should be able to jump to the template from the budget view without hunting through the nav. | LOW | An "Edit template" link on the budget page or a per-item "Save to template" action. Single nav jump, no modal complexity. |
+
+### Anti-Features (Commonly Requested, Often Problematic)
+
+Features that seem good but create problems in this context.
+
+| Feature | Why Requested | Why Problematic | Alternative |
+|---------|---------------|-----------------|-------------|
+| AI-suggested amounts based on spending history | "Smart defaults should learn from me over time" | Requires enough historical data (users don't have it at setup), an ML model or LLM call, and privacy tradeoffs. The payoff is low when static defaults work fine for first-run. | Static curated defaults per item type. After 3+ months of use, a "Review your template" prompt is sufficient. |
+| Mandatory wizard (no escape) | "Force users to complete setup so they have a working budget" | Patronizing for returning users; creates frustration for users who want to explore before committing. YNAB's old onboarding got negative feedback for being too locked-in; they added a flexible checklist in Oct 2025 for this reason. | Skippable wizard with a prominent resume-later CTA. Show a "Complete setup" banner if template is empty. |
+| Auto-sync with bank accounts | "Automatically populate actuals from transactions" | Plaid/bank integrations add significant infrastructure cost, security scope, and maintenance burden. Out of scope for a self-hosted personal tool. | Manual actual entry (inline editing, already implemented) with optional import as a future feature. |
+| Complex wizard with 6+ steps | "Guide the user through every aspect of budgeting" | Drop-off increases sharply with each step beyond 3. Users who see step 4 of 7 abandon setup entirely. | Max 3 steps: (1) Income, (2) Recurring items, (3) Review + confirm. Everything else is editable post-setup. |
+| Per-item recurrence configuration in wizard | "Let users set whether each item is weekly, monthly, etc." | Adds decision burden during setup. The app model is monthly budgeting — every item is implicitly monthly. Edge cases (weekly, biweekly) should be post-setup configuration. | Monthly-only assumption during wizard. Users can edit frequency on the template page after setup. |
+| Gamification / streaks for budget tracking | "Engage users to check in daily" | Budget apps that add gamification often feel gimmicky for a personal finance tool. The target user is tracking a spreadsheet replacement — they want data, not achievements. | Progress indicators (spent X% of budget) provide motivation without game mechanics. |
+| Duplicate "Quick Add" page alongside inline add | "Keep the existing page and add inline too" | Two ways to do the same thing creates confusion about which to use. The standalone Quick Add page has no added value over an inline approach. | Replace entirely with inline add-from-library on the budget view. Remove the nav link for the old Quick Add page. |

+
+### Dependency Notes
+
+- **Wizard depends on pre-seeded library:** The wizard presents pre-filled common items. These must exist in the database (or a constants file) before the wizard can show them. This is the foundational data concern for v2.0.
+- **Auto-creation depends on template having content:** If the user skips the wizard entirely, auto-creation generates an empty budget (no items). The UI must handle this gracefully — show empty-state with "Set up your template" CTA.
+- **Inline add replaces Quick Add page:** This is a replacement, not an addition. The Quick Add page should be removed from the nav. The backend endpoint it uses can be repurposed or kept as the inline add trigger.
+- **Dashboard correctness is a prerequisite:** The "dashboard = this month at a glance" feature is only meaningful if the data it displays is accurate. Data correctness fix must happen before or alongside the dashboard simplification.
+
+---
+
+## MVP Definition
+
+This is v2.0 of an existing working app. "MVP" here means: what is the minimum set of changes that delivers the simplified UX without regressions?
+
+### Launch With (v2.0 — Core UX Simplification)
+
+- [ ] Wizard-style template setup — 3-step flow: income → common items (pre-filled, editable) → review — skippable
+- [ ] Pre-seeded library with ~15-20 common items grouped by category type (rent, car insurance, groceries, utilities, car payment, etc.)
+- [ ] Smart amount defaults in wizard (static sensible values per item — not AI)
+- [ ] Running balance during wizard (income minus sum of selected items)
+- [ ] Auto-create current month budget from template on first visit (backend trigger, silent)
+- [ ] Toast notification on first auto-creation only ("Your April budget was created from your template")
+- [ ] Inline add-from-library on the budget view (replaces Quick Add page)
+- [ ] Remove Quick Add from navigation
+- [ ] Dashboard summary cards correctly reflect current month budget data
+- [ ] Empty state CTAs for: empty template, empty dashboard, empty budget
+
+### Add After Core Ships (v2.x)
+
+- [ ] "Edit template" shortcut from budget view — once core flow is working, add the escape hatch
+- [ ] Persistent "this month" summary widget on dashboard — adds value once data is correct
+- [ ] "Complete setup" banner for users who skipped wizard but have empty template
+- [ ] Wizard resume-later state (save partial wizard progress) — only needed if drop-off is observed
+
+### Future Consideration (v3+)
+
+- [ ] Income-based spending recommendations (percentages by category type)
+- [ ] "Review your template" prompt after 3 months of use
+- [ ] CSV/bank import for actuals — mentioned as future feature in PROJECT.md
+- [ ] Recurring transaction automation — mentioned as future in PROJECT.md

+## Wizard Flow Design Notes
+
+Based on research into YNAB, EveryDollar, and UX onboarding best practices, the recommended wizard structure is:
+
+**Step 1 — Income**
+- Single question: "What's your monthly take-home income?"
+- Single number input + currency formatting
+- Skip option: "I'll add this later"
+- Sets the anchor for running balance in step 2
+
+**Step 2 — Recurring Items**
+- Pre-loaded list of common items grouped by type (bills, variable expenses, debts, savings, investments)
+- Each item has a checkbox (on by default for high-likelihood items, off for lower-likelihood)
+- Editable amount field per item (prefilled with static sensible default)
+- Running balance updates live: "Remaining to allocate: $X"
+- "Add custom item" inline for items not in the list
+- Skip option: "I'll set this up manually"
+
+**Step 3 — Review**
+- Summary of selected items by group
+- Total income, total allocated, remaining
+- "Create my template" CTA — writes to the template table
+- "Go back" link to step 2
+
+**Post-wizard:**
+- Auto-create current month budget from template (immediate)
+- Show toast: "Your [Month] budget has been created"
+- Land on budget view for current month
+
+**Confidence:** MEDIUM — pattern validated by YNAB (beginner template import), EveryDollar (wizard-style), and UX onboarding research. 3-step max is validated by drop-off research (complexity above 3 steps correlates with abandonment).

+
+## Inline Add-From-Library Design Notes
+
+The existing Quick Add page uses a library of one-off items (`quick_add_items` table). In v2.0, this interaction moves inline to the budget view.
+
+**Recommended pattern (based on fintech UX research):**
+- Trigger: "Add item" button in each category section header on the budget view
+- Mechanism: A slide-in panel or modal sheet (not a full page navigation)
+- Contents: Category pre-selected (from which section was clicked); searchable list of library items for that category type; amount field; description field
+- On confirm: Item added to budget for the month, totals update immediately
+- On dismiss: Panel closes, no navigation
+
+**Why panel/sheet over modal:**
+- Modals block background context; users lose their place in the budget
+- A slide-in sheet (shadcn/ui Sheet component) keeps the budget visible alongside the picker
+- Smashing Magazine (2026): "modals work for quick confirmations; sheets work for contextual data entry tasks"
+
+**Why not keep the separate Quick Add page:**
+- Two surfaces for the same action creates confusion (which should I use?)
+- The separate page breaks the flow — user must navigate away, losing their place
+- Inline keeps the budget view as the single place for monthly budget work
