# Phase 02 Plan 01: Auth Page Branding Summary

Pastel gradient login and register pages with a gradient text wordmark and shadcn Alert errors — auth screens transformed from plain white cards into the first branded touchpoint.

## What Was Built

Both LoginPage and RegisterPage received identical branding treatment:

1. **Gradient background** — inline `style` with `linear-gradient(135deg, ...)` using `palette.saving.light`, `palette.bill.light`, and `palette.investment.light` light shades (~oklch 0.95-0.96 chroma 0.03-0.04). Replaces the `bg-background` Tailwind class.

2. **Gradient text wordmark** — `<span data-testid="wordmark">` with CSS text-clip gradient from primary blue (hue 260) to pink-violet (hue 320) renders the app name in the card header below the page title.

3. **shadcn Alert errors** — `Alert variant="destructive"` with `AlertCircle` icon and `AlertDescription` replaces the plain `<p className="text-sm text-destructive">` error display. Provides semantic `role="alert"` for a11y.

4. **Card shadow** — `shadow-lg` added to Card for visual lift against the gradient background.

## Tasks Completed

| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | Install shadcn Alert and create test scaffolds | dfd88de | alert.tsx, LoginPage.test.tsx, RegisterPage.test.tsx |
| 2 | Brand LoginPage and RegisterPage | 381a060 | LoginPage.tsx, RegisterPage.tsx |

## Verification Results

- All 6 tests pass (AUTH-01 through AUTH-04): `bun vitest run src/pages/`
- Full test suite: 35 tests pass, 0 failures
- Production build: `bun run build` succeeds with zero errors

## Deviations from Plan

None — plan executed exactly as written.

## Self-Check: PASSED
