+# Phase 1 Plan 01: Design Token Foundation Summary
+
+Pastel oklch CSS variable system and palette.ts module established as the foundation layer for all subsequent visual work, with vitest test infrastructure installed and 20 unit tests passing.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Install test infrastructure and set up vitest | cbf3552 | frontend/package.json, frontend/vite.config.ts, frontend/src/test-setup.ts |
+| 2 | Replace CSS tokens with pastel oklch values and add success/warning tokens | 3f97d07 | frontend/src/index.css |
+| 3 | Create palette.ts and palette.test.ts (TDD) | d5fc10d (RED), 6859b30 (GREEN) | frontend/src/lib/palette.ts, frontend/src/lib/palette.test.ts |
+
+## What Was Built
+
+**Pastel CSS variable system (`frontend/src/index.css`):**
+- All `:root` tokens now use oklch values with non-zero chroma (lavender tint, hue ~280-290) except for the intentionally pure-white `--card` and `--popover`
+- `--chart-1` through `--chart-5` mapped to category base colors (bill=blue 250, variable_expense=amber 85, debt=rose 15, saving=violet 280, investment=pink 320)
+- New `--success` (green 145) and `--warning` (amber 75) semantic tokens in `:root`
+- `--color-success` and `--color-warning` registered in `@theme inline` enabling Tailwind utilities `text-success`, `text-warning`
+
+**Typed palette module (`frontend/src/lib/palette.ts`):**
+- `CategoryType` union: income | bill | variable_expense | debt | saving | investment | carryover
+- `CategoryShades` interface with light/medium/base oklch strings
+- `palette` Record — single source of truth, base colors match CSS chart tokens
+- `headerGradient(type)` — returns `React.CSSProperties` with `linear-gradient(to right, light, medium)`
+- `overviewHeaderGradient()` — multi-stop gradient (carryover.light → saving.light → income.light)
+- `amountColorClass(opts)` — returns `text-success`/`text-warning`/`text-destructive`/`''` per locked rules
+
+**Test infrastructure:**
+- vitest 4.0.18 with jsdom environment and globals
+- `test-setup.ts` imports `@testing-library/jest-dom` matchers
+- 20 unit tests covering all exports and edge cases — all passing
+
+## Decisions Made
+
+1. `--card` and `--popover` intentionally remain `oklch(1 0 0)` (pure white) per locked design decision — cards float visually on the tinted background
+2. `--success-foreground` and `--warning-foreground` use near-white `oklch(0.99 0 0)` — neutral foreground on colored semantic backgrounds is correct and intentional
+3. Sidebar tokens use slightly deeper lavender (hue 280, chroma 0.01-0.02) vs background (hue 290, chroma 0.005) for subtle visual distinction
+4. `overviewHeaderGradient()` uses carryover/saving/income lights (sky→lavender→green) for the FinancialOverview header identity
