# Phase 17 Plan 04: Brand Wiring Summary

**BrandSlot logo img wired from seam with no LoginPage change; favicon set + theme-color in index.html; manifest maskable icon fixed to /icon-maskable-512.png; brand accent #e8915a applied consistently across tokens.css, index.html, and vite.config.ts**

## Performance

- **Duration:** ~4 min
- **Started:** 2026-06-18T16:47:28Z
- **Completed:** 2026-06-18T16:51:02Z
- **Tasks:** 2/2
- **Files modified:** 4

## Accomplishments

### Task 1: BrandSlot logo img + --brand-logo-border-radius

Replaced the Phase 19 placeholder `<div aria-hidden>FS</div>` with a decorative `<img>` element:

```tsx
<img
  src="/logo.svg"
  alt=""
  aria-hidden="true"
  style={{
    width: 'var(--brand-logo-size, 48px)',
    height: 'var(--brand-logo-size, 48px)',
    borderRadius: 'var(--brand-logo-border-radius)',
    margin: '0 auto var(--space-2, 8px)',
    display: 'block',
    aspectRatio: '1 / 1',
    objectFit: 'contain',
    flexShrink: 0,
  }}
/>
```

- `h1` "FamilySync" and tagline `p` unchanged
- `LoginPage.tsx` NOT in the diff (seam contract honored)
- `dangerouslySetInnerHTML` NOT used (T-05-24 invariant maintained)
- Updated `--brand-logo-border-radius: 50%` → `0` in tokens.css (approved 17-02: SVG draws its own rx=104 background)

### Task 2: index.html favicons + theme-color, vite.config.ts manifest fix, tokens.css accent

**index.html changes:**
- Added `<link rel="icon" href="/favicon.svg" type="image/svg+xml" />` (SVG first, modern browsers)
- Added `<link rel="icon" href="/favicon.ico" sizes="any" />` (legacy fallback)
- Updated `theme-color` from `#4A90D9` → `#e8915a`
- `apple-touch-icon` already had `sizes="180x180"` (was already present)

**vite.config.ts changes:**
- Fixed maskable icon: `/icon-512.png` with `purpose: 'maskable'` → `/icon-maskable-512.png` (the separate safe-zone file, 8627 B)
- Updated `theme_color: '#4A90D9'` → `'#e8915a'`

**tokens.css changes:**
- Updated `--color-member-0: #4a90d9` → `#e8915a` (warm amber, operator-approved Variant B)
- `--sx-color-primary: var(--color-member-0)` follows automatically (no additional edit needed)

## Task Commits

| Task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | BrandSlot logo img + border-radius token | ce95aa3 | BrandSlot.tsx, tokens.css |
| 2 | Favicons + theme-color + maskable fix + accent | df578fd | index.html, tokens.css, vite.config.ts |

## Verification

### Automated checks passed

- `grep -q 'src="/logo.svg"' BrandSlot.tsx` — OK
- `grep -q 'alt=""' BrandSlot.tsx` — OK
- `grep -q 'FamilySync' BrandSlot.tsx` (h1 intact) — OK
- `dangerouslySetInnerHTML` only in security comment, not in JSX — OK
- `--brand-logo-border-radius: 0` in tokens.css — OK
- `--color-member-0: #e8915a` in tokens.css — OK
- `favicon.svg` link in index.html — OK
- `favicon.ico` link in index.html — OK
- `theme-color: #e8915a` in index.html — OK
- `icon-maskable-512.png` in vite.config.ts manifest — OK
- No `icon-512.png` with `maskable` purpose in manifest — OK
- `theme_color: '#e8915a'` in vite.config.ts — OK
- `pnpm --filter @familysync/pwa build` — exits 0

### Build output verified

- `dist/index.html` contains `favicon.svg`, `favicon.ico`, `theme-color: #e8915a`
- `dist/manifest.webmanifest` contains `icon-maskable-512.png` with `"purpose":"maskable"`, `"theme_color":"#e8915a"`
- JS bundle contains `logo.svg` with `alt:""` (decorative img confirmed in minified output)

### playwright-cli observation

The Vite dev server at :5173 is the main-repo instance (not the worktree), so the live browser showed the pre-existing placeholder. Build artifact verification was used as the authoritative check — `dist/manifest.webmanifest` and `dist/index.html` confirm all wiring is correct. The production-equivalent build passes cleanly.

## Deviations from Plan

None — plan executed exactly as written. All approved branding decisions from 17-02 applied verbatim:
- `--color-member-0: #e8915a` (Variant B warm amber)
- `--brand-logo-border-radius: 0` (SVG self-rounds)
- Favicon order per UI-SPEC wiring contract (SVG first, ICO second)

## Threat Surface Scan

No new trust boundaries introduced. All changes are static asset references and token values:
- `BrandSlot.tsx` uses `<img>` with empty alt + aria-hidden — no executable content, no user input, no dangerouslySetInnerHTML
- `index.html` favicon links and theme-color meta — committed static references
- `vite.config.ts` manifest — committed static icon references at known paths
- `tokens.css` value updates — no new surface

No new threat flags above the LOW level accepted in the plan's threat model.

## Self-Check: PASSED

- `apps/pwa/src/components/BrandSlot.tsx` — modified, committed at ce95aa3
- `apps/pwa/src/styles/tokens.css` — modified, committed at ce95aa3 (border-radius) + df578fd (color)
- `apps/pwa/index.html` — modified, committed at df578fd
- `apps/pwa/vite.config.ts` — modified, committed at df578fd
- `dist/manifest.webmanifest` — correct maskable + theme_color confirmed
- Build: exits 0
