# Phase 5: Design System Token Rework - Pattern Map

**Mapped:** 2026-04-20
**Files analyzed:** 14 files (1 CSS + 2 chart components + 1 shared component + 9 pages + 1 component)
**Analogs found:** 14 / 14 (all files are modifications of existing code — no new files created)

## Pattern Assignments

### `src/index.css` (config, CSS tokens)

**Analog:** self — authoritative token source, no external analog needed.

**Current `@theme inline` block** (lines 1-99, full file):

```css
@import "tailwindcss";
@custom-variant dark (&:is(.dark *));

@theme inline {
  --color-background: oklch(0.98 0.005 260);   /* → 0.01 chroma (warm) */
  --color-foreground: oklch(0.25 0.02 260);

  /* ... (base tokens unchanged) ... */

  /* Category fill tokens — RAISE chroma to 0.22+ */
  --color-income-fill: oklch(0.68 0.19 155);   /* → 0.22 */
  --color-bill-fill: oklch(0.65 0.19 25);       /* → 0.22 */
  --color-variable-expense-fill: oklch(0.70 0.18 50); /* → 0.22 */
  --color-debt-fill: oklch(0.60 0.20 355);      /* → 0.23 */
  --color-saving-fill: oklch(0.68 0.18 220);    /* → 0.22 */
  --color-investment-fill: oklch(0.65 0.18 285); /* → 0.22 */

  /* Chart vars — DELETE these 5 lines entirely */
  --color-chart-1: oklch(0.72 0.14 155);
  --color-chart-2: oklch(0.7 0.14 25);
  --color-chart-3: oklch(0.72 0.14 50);
  --color-chart-4: oklch(0.65 0.16 355);
  --color-chart-5: oklch(0.72 0.14 220);

  --radius: 0.625rem;  /* → 0 */
}

@layer base {
  * { @apply border-border; }
  body {
    @apply bg-background text-foreground;
    font-feature-settings: "rlig" 1, "calt" 1;
  }
}
```

**Changes to make in this file:**
1. Line 7: `--color-background: oklch(0.98 0.005 260)` → `oklch(0.98 0.01 260)`
2. Lines 65-70: raise all six `--color-*-fill` chroma values to 0.22+ per CONTEXT.md
3. Lines 52-57: delete `--color-chart-1` through `--color-chart-5` entirely
4. Line 72: `--radius: 0.625rem` → `--radius: 0`
5. After `@layer base` block: add CSS override selectors for Recharts and Sonner (see Shared Patterns section below)

---

### `src/components/dashboard/charts/SpendBarChart.tsx` (component, transform)

**Analog:** `src/components/dashboard/charts/IncomeBarChart.tsx`

**Current `Bar` radius props** (lines 64-80):

```tsx
<Bar
  dataKey="budgeted"
  fill="var(--color-budgeted)"
  radius={4}           /* → radius={0} */
/>
<Bar dataKey="actual" radius={4}>   /* → radius={0} */
  {data.map((entry, index) => (
    <Cell
      key={index}
      fill={
        entry.actual > entry.budgeted
          ? "var(--color-over-budget)"
          : `var(--color-${entry.type}-fill)`  /* already correct — no change */
      }
    />
  ))}
</Bar>
```

**Changes to make in this file:**
- Line 67: `radius={4}` → `radius={0}`
- Line 69: `radius={4}` → `radius={0}`
- `chartConfig` (lines 31-34): no change needed — `actual` already references `--color-muted-foreground`, `budgeted` references `--color-budget-bar-bg`; neither references deleted `--color-chart-*` vars.

---

### `src/components/dashboard/charts/IncomeBarChart.tsx` (component, transform)

**Analog:** `src/components/dashboard/charts/SpendBarChart.tsx`

**Current `Bar` radius props** (lines 54-69):

```tsx
<Bar
  dataKey="budgeted"
  fill="var(--color-budgeted)"
  radius={[4, 4, 0, 0]}    /* → radius={0} */
/>
<Bar dataKey="actual" radius={[4, 4, 0, 0]}>  /* → radius={0} */
  {data.map((entry, index) => (
    <Cell
      key={index}
      fill={
        entry.actual > entry.budgeted
          ? "var(--color-over-budget)"
          : "var(--color-income-fill)"   /* already correct — no change */
      }
    />
  ))}
</Bar>
```

**Current `chartConfig`** (lines 26-29):

```tsx
const chartConfig = {
  budgeted: { label: "Budgeted", color: "var(--color-budget-bar-bg)" },
  actual: { label: "Actual", color: "var(--color-income-fill)" },  /* already references fill token */
} satisfies ChartConfig
```

**Changes to make in this file:**
- Line 57: `radius={[4, 4, 0, 0]}` → `radius={0}`
- Line 59: `radius={[4, 4, 0, 0]}` → `radius={0}`
- `chartConfig`: no change needed — already references `--color-income-fill`, not a deleted `--color-chart-*` var.

---

### `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 */
<span
  className="inline-block size-3 shrink-0 rounded-full"
  style={{ backgroundColor: `var(--color-${entry.type}-fill)` }}
/>

/* After — remove rounded-full entirely */
<span
  className="inline-block size-3 shrink-0"
  style={{ backgroundColor: `var(--color-${entry.type}-fill)` }}
/>
```

**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`

This single change propagates the header-to-content gap increase to all 9 pages that use `PageShell`.

---

### `src/components/dashboard/DashboardSkeleton.tsx` (component, skeleton)

**Analog:** Skeleton patterns from `CategoriesPage.tsx` lines 98-114 and `BudgetDetailPage.tsx` lines 284-306.

**Hardcoded `rounded-*` locations in this file:**

```tsx
/* Line 35 — chart placeholder */
<Skeleton className="h-[250px] w-full rounded-md" />  /* remove rounded-md */

/* Line 43 — chart placeholder */
<Skeleton className="h-[250px] w-full rounded-md" />  /* remove rounded-md */

/* Line 51 — chart placeholder */
<Skeleton className="h-[250px] w-full rounded-md" />  /* remove rounded-md */

/* Line 59 — collapsible section row */
<div className="flex items-center gap-3 rounded-md border-l-4 ...">  /* remove rounded-md */

/* Lines 63-64 — inline summary badges */
<Skeleton className="h-5 w-24 rounded-full" />  /* remove rounded-full — CRITICAL: rounded-full is 9999px, not from --radius */
<Skeleton className="h-5 w-24 rounded-full" />  /* remove rounded-full */
```

**Also: spacing upgrades**:

```tsx
/* Line 20 — top-level container */
<div className="flex flex-col gap-6">   /* → gap-8 */

/* Line 22 — summary cards grid */
<div className="grid gap-4 sm:grid-cols-2 lg:grid-cols-3">  /* → gap-6 */

/* Line 29 — chart grid */
<div className="grid gap-6 md:grid-cols-2 lg:grid-cols-3">  /* → gap-8 */
```

---

### `src/components/dashboard/CategorySection.tsx` (component, list item)

**Analog:** Group heading divs in `BudgetDetailPage.tsx` lines 352-356, `CategoriesPage.tsx` lines 134-137, `TemplatePage.tsx` lines 292-295.

**The hardcoded `rounded-md`** (line 73):

```tsx
/* Before */
<button
  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"
  style={{ borderLeftColor: categoryColors[type] }}
>

/* After — remove rounded-md */
<button
  className="group flex w-full items-center gap-3 border-l-4 bg-card px-4 py-3 text-left hover:bg-muted/40 transition-colors"
  style={{ borderLeftColor: categoryColors[type] }}
>
```

**Changes to make in this file:**
- Line 73: remove `rounded-md` from the button's className.

---

### `src/components/dashboard/charts/ChartEmptyState.tsx` (component, empty state)

**Current `rounded-lg`** (line 12):

```tsx
/* Before */
className={cn(
  "flex min-h-[250px] w-full items-center justify-center rounded-lg border border-dashed ...",
  className
)}

/* After — remove rounded-lg */
className={cn(
  "flex min-h-[250px] w-full items-center justify-center border border-dashed ...",
  className
)}
```

**Changes to make in this file:**
- Line 12: remove `rounded-lg` from the className string.

---

### `src/components/QuickAddPicker.tsx` (component, picker)

**Analog:** Same pattern as `BudgetDetailPage.tsx` line 496 and `TemplatePage.tsx` line 385 — `size-2 rounded-full` color swatch dots used as SelectLabel decorators.

**Hardcoded `rounded-*` locations:**

```tsx
/* Line 156 — picker item button */
className="flex w-full items-center gap-2 rounded-sm px-2 py-1.5 ..."
/* → remove rounded-sm */

/* Line 201 — SelectLabel category dot */
<div
  className="size-2 rounded-full"
  style={{ backgroundColor: categoryColors[type] }}
/>
/* → remove rounded-full */
```

**Changes to make in this file:**
- Line 156: remove `rounded-sm` from className.
- Line 201: remove `rounded-full` from className.

---

### `src/pages/DashboardPage.tsx` (page, request-response)

**Current spacing** (lines 186, 207):

```tsx
/* Line 186 — DashboardContent top-level wrapper */
<div className="space-y-6">     /* → space-y-8 */

/* Line 207 — chart grid */
<div className="grid gap-6 md:grid-cols-2 lg:grid-cols-3">   /* → gap-8 */
```

**Changes to make in this file:**
- Line 186: `space-y-6` → `space-y-8`
- Line 207: `gap-6` → `gap-8`

No hardcoded `rounded-*` classes in this file.

---

### `src/pages/BudgetListPage.tsx` (page, CRUD)

**Analog:** `BudgetDetailPage.tsx` lines 242-256 — same `rounded-md border p-3` container pattern.

**Hardcoded `rounded-md`** (line 243):

```tsx
/* Before */
<div className="flex items-center gap-3 rounded-md border p-3">

/* After */
<div className="flex items-center gap-3 border p-3">
```

**Spacing:** Check for `gap-4`, `gap-6`, `space-y-*` patterns and apply standard upgrades:
- `gap-4` → `gap-6`
- `gap-6` → `gap-8`
- `space-y-6` → `space-y-8`

---

### `src/pages/BudgetDetailPage.tsx` (page, CRUD)

**Analog:** `CategoriesPage.tsx` and `TemplatePage.tsx` — structurally identical page pattern (group headings, Tables, PageShell).

**Hardcoded `rounded-*` locations** (confirmed from RESEARCH.md inventory):

| Line | Current | Action |
|------|---------|--------|
| 290 | `rounded-sm` on skeleton header div | Remove |
| 303 | `rounded-md` on `<Skeleton>` className | Remove |
| 353 | `rounded-sm` on budget item group heading div | Remove |
| 439 | `rounded-md` on summary totals box | Remove |
| 497 | `rounded-full` on SelectLabel category dot | Remove |

**Line 353 group heading** (current pattern to modify):

```tsx
/* Before */
<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] }}
>

/* After */
<div
  className="mb-2 flex items-center gap-3 border-l-4 bg-muted/30 px-3 py-2"
  style={{ borderLeftColor: categoryColors[type] }}
>
```

**Line 439 summary box** (current pattern to modify):

```tsx
/* Before */
<div className="rounded-md border p-4">

/* After */
<div className="border p-4">
```

**Spacing upgrades:**
- `space-y-8` already present at line 338 (inner grouped content) — verify no `space-y-6` / `gap-6` remaining
- Check for `p-4` on card content wrappers → `p-6`

---

### `src/pages/TemplatePage.tsx` (page, CRUD)

**Analog:** `BudgetDetailPage.tsx` — same group heading + Table structure, same skeleton pattern.

**Hardcoded `rounded-*` locations** (confirmed from RESEARCH.md inventory):

| Line | Current | Action |
|------|---------|--------|
| 250 | `rounded-sm` on skeleton group heading div | Remove |
| 256 | `rounded-full` on `<Skeleton>` className | Remove |
| 258 | `rounded-md` on `<Skeleton>` className | Remove |
| 292 | `rounded-sm` on template item group heading div | Remove |
| 385 | `rounded-full` on SelectLabel category dot | Remove |

**Line 292 group heading** (current):

```tsx
/* Before */
<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] }}
>
```

Same removal pattern as `BudgetDetailPage.tsx` line 353.

**Line 385 SelectLabel dot** (current):

```tsx
/* Before — same pattern as BudgetDetailPage line 497 */
<div
  className="size-2 rounded-full"
  style={{ backgroundColor: categoryColors[type] }}
/>
/* After: remove rounded-full */
```

**Spacing upgrades** (current at lines 247, 268, 287):
- Line 247: `space-y-6` → `space-y-8` (skeleton wrapper)
- Line 268: `gap-6` → `gap-8` (TemplatePage own flex header, not using PageShell)
- Line 287: `space-y-6` → `space-y-8` (main content groups)

---

### `src/pages/CategoriesPage.tsx` (page, CRUD)

**Analog:** `BudgetDetailPage.tsx` / `TemplatePage.tsx` — structurally identical.

**Hardcoded `rounded-*` locations** (confirmed from RESEARCH.md inventory):

| Line | Current | Action |
|------|---------|--------|
| 101 | `rounded-sm` on skeleton group heading div | Remove |
| 107 | `rounded-full` on `<Skeleton>` className | Remove |
| 108 | `rounded-md` on `<Skeleton>` className | Remove |
| 134 | `rounded-sm` on category group heading div | Remove |

**Line 134 group heading** (current):

```tsx
/* Before */
<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] }}
>
/* After: remove rounded-sm */
```

**Spacing upgrades** (current at lines 98, 130):
- Line 98: `space-y-6` → `space-y-8` (skeleton wrapper)
- Line 130: `space-y-6` → `space-y-8` (main content groups)

---

### `src/pages/QuickAddPage.tsx` (page, CRUD)

**Analog:** `CategoriesPage.tsx` — same row-list layout, same Skeleton usage.

**Hardcoded `rounded-*` locations** (confirmed from RESEARCH.md inventory):

| Line | Current | Action |
|------|---------|--------|
| 98 | `rounded-full` on `<Skeleton>` className | Remove |
| 100 | `rounded-md` on `<Skeleton>` className | Remove |

**Current skeleton block** (lines 93-105):

```tsx
<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" />   /* line 98 — remove rounded-full */
      <Skeleton className="h-4 w-36" />
      <Skeleton className="ml-auto h-7 w-7 rounded-md" />  /* line 100 — remove rounded-md */
    </div>
  ))}
</div>
```

No major spacing changes in this file (list layout, not grid/section-based).

---

### `src/pages/SettingsPage.tsx` (page, request-response)

**Analog:** `CategoriesPage.tsx` — PageShell wrapper, Card with CardContent.

**No hardcoded `rounded-*` classes** in this file (Card uses token cascade).

**Spacing upgrade** (line 87):

```tsx
/* Before — CardContent internal spacing */
<CardContent className="space-y-4 pt-6">   /* → space-y-6 */
```

**Changes to make in this file:**
- Line 87 (and corresponding skeleton line 69): `space-y-4` → `space-y-6` inside `CardContent`

---

### `src/pages/LoginPage.tsx` and `src/pages/RegisterPage.tsx` (pages, request-response)

**Analog:** `SettingsPage.tsx` — Card-based page, no group headings.

Per RESEARCH.md: "Card already uses `--radius` token cascade." No hardcoded `rounded-*` classes confirmed. No `--color-chart-*` references.

**Minimal changes:** Verify `p-4` → `p-6` in any card content wrappers if present. No spacing grids to upgrade. Treat as low-touch pages in implementation.

---

## 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
```

## No Analog Found

None — all files are modifications of existing code. No net-new files are created in this phase.

---

## 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)
