Packages: +3 -5
dependencies removed:
- @fontsource/inter 5.2.8
- @fontsource/jetbrains-mono 5.2.8
Done in 1.4s
```

**Build — Docs**: ✅ Passed

```bash
pnpm --dir clients/web --filter @corvus/docs run build
build complete: 78 page(s) built
```

**Build — Marketing**: ✅ Passed

```bash
pnpm --dir clients/web --filter @corvus/marketing run build
build complete: 1 page(s) built
```

**Tests — Chat**: ✅ 99 passed / 0 failed / 0 skipped

**Tests — Dashboard**: ✅ 185 passed / 0 failed / 0 skipped

**Build — Chat**: ⚠️ Failed (pre-existing, unrelated to this change)

```text
src/components/HealthIndicator.spec.ts(97,5): error TS2349: This expression is not callable.
```

**Build — Dashboard**: ⚠️ Failed (pre-existing, unrelated to this change)

```text
src/components/sessions/SessionFilters.vue(33,3): error TS2769: No overload matches this call.
```

These two TS errors remain outside the Nothing design system scope and were already present during the previous verification pass. They do not invalidate the design-system-specific fixes that were requested in this re-check.

**Coverage**: ➖ Not configured

## Re-validation of Previously Failing Items

| Item | Previous State | Current State | Evidence |
|------|----------------|---------------|----------|
| pnpm catalog / dependency strategy | ❌ Broken | ✅ Fixed | `clients/web/package.json` no longer contains old font deps; `pnpm --dir clients/web install` succeeds and removes `@fontsource/inter` + `@fontsource/jetbrains-mono` |
| Docs font imports resolve structurally | ❌ Broken | ✅ Fixed | `clients/web/apps/docs/src/styles/custom.css:8-12` now uses `@import "..."`; docs build passes |
| Marketing font imports resolve structurally | ❌ Broken | ✅ Fixed | `clients/web/apps/marketing/src/styles/global.css:11-15` now uses `@import "..."`; marketing build passes |
| Reduced motion `!important` | ❌ Missing | ✅ Fixed | `clients/web/packages/shared/base.css:10-18` and `clients/web/apps/docs/src/styles/custom.css:473-480` |
| Button/Input micro duration | ❌ Wrong | ✅ Fixed | `clients/web/packages/ui/src/components/Button.vue:41`, `clients/web/packages/ui/src/components/Input.vue:40` |

## Proposal Success Criteria Reassessment

| Success Criterion | Status | Evidence |
|------------------|--------|----------|
| All 4 web apps render correctly with Nothing visual language in both dark and light themes | ⚠️ Partial runtime proof | Static implementation is complete across shared/UI/chat/dashboard/docs/marketing; docs and marketing now build. Full cross-app browser proof for both themes still not automated. |
| Zero CSS custom properties use non-canonical naming | ✅ Met | Canonical `--corvus-*` naming in `clients/web/packages/shared/nothing-theme.css`; no legacy token refs found in prior audit. |
| All `--corvus-*` tokens have both dark and light values defined | ✅ Met | `clients/web/packages/shared/nothing-theme.css` contains dark defaults plus light overrides. |
| Button and Input render without shadows, glows, or gradients | ✅ Met | `Button.vue` and `Input.vue` contain no prohibited shadow/glow/gradient styles. |
| Tailwind utility classes work in chat and dashboard | ⚠️ Partial | `@theme` bridge exists in `clients/web/apps/chat/src/style.css:4` and `clients/web/apps/dashboard/src/style.css:4`; no runtime browser proof executed here. |
| Starlight docs responds correctly to `[data-theme="light"]` and `[data-theme="dark"]` | ⚠️ Partial | Mapping exists in `clients/web/apps/docs/src/styles/custom.css:33-77`; docs build passes; no runtime browser toggle proof executed here. |
| Font bundle delta is neutral or positive | ⚠️ Unverified | Install now succeeds, but no bundle-size comparison was run in this pass. |
| No WCAG AA contrast failures for primary/secondary text | ✅ Met (static token validation) | Token pairs match the specified compliant values in the spec and implementation. |
| Old `theme.css`, `app-shell.css`, `tokens.css` removed with no remaining references | ✅ Met | Old files remain deleted; deletion re-confirmed. |
| `prefers-color-scheme` media query triggers correct theme | ⚠️ Partial | CSS mechanism exists in `nothing-theme.css`; no browser emulation proof executed in this pass. |

## Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|------------|--------|-------|
| Nothing Color Token Catalog | ✅ Implemented | Tokens remain complete and canonical in `nothing-theme.css` |
| Nothing Typography Tokens | ✅ Implemented | Font families, composable scale, weights present |
| Nothing Spacing Tokens | ✅ Implemented | 8px-based scale intact |
| Nothing Radius Tokens | ✅ Implemented | Includes `none`, `technical`, `input`, `card`, `card-lg`, `pill` |
| Nothing Motion Tokens | ✅ Implemented | Micro/default/slow durations and easing token present |
| Theme Switching | ✅ Implemented | Dark default + `prefers-color-scheme` + manual `[data-theme]` override remain intact |
| Font Loading | ✅ Implemented | Dependency strategy now consistent enough to install and build docs/marketing successfully |
| Tailwind v4 Bridge | ✅ Implemented | Present in chat and dashboard |
| Button Restyling | ✅ Implemented | Now uses required micro transition duration |
| Input Restyling | ✅ Implemented | Now uses required micro transition duration |
| Docs Migration | ✅ Implemented | Starlight mapping intact; build passes |
| Marketing Migration | ✅ Implemented | Nothing styling intact; build passes |
| Reduced Motion | ✅ Implemented | Required `!important` flags now present |
| Legacy Cleanup | ✅ Implemented | Old shared files still deleted |

## Coherence (Design)

| Decision | Followed? | Notes |
|----------|-----------|-------|
| ADR-1: Canonical `corvus.*` naming | ✅ Yes | No regression found |
| ADR-2: `prefers-color-scheme` + manual override | ✅ Yes | Mechanism still matches design |
| ADR-3: Parallel token layer | ✅ Yes | New theme/shell files are in place; old files remain removed |
| Tailwind `@theme` per app | ✅ Yes | Chat/dashboard unchanged and consistent |
| Starlight `[data-theme]` integration | ✅ Yes | Docs mappings remain correct |
| Font loading per-app via `@fontsource` | ✅ Yes | Astro CSS imports now structurally valid for Vite/PostCSS resolution |

## Issues Found

**CRITICAL** (must fix before archive):
None.

**WARNING** (should fix):

1. **Runtime/browser proof still incomplete**:
   - No Playwright/browser verification was executed in this pass for `prefers-color-scheme`, manual `[data-theme]` switching, Tailwind utility resolution under both themes, or Starlight theme toggle behavior.

2. **Font bundle delta still unverified**:
   - The install/build pipeline is fixed, but no before/after artifact size comparison was run, so the proposal’s bundle-delta criterion remains unproven.

3. **Pre-existing unrelated TS build failures remain in chat/dashboard**:
   - `clients/web/apps/chat/src/components/HealthIndicator.spec.ts:97`
   - `clients/web/apps/dashboard/src/components/sessions/SessionFilters.vue:33`
   These are outside the design-system scope but still affect full workspace green builds.

**SUGGESTION** (nice to have):

1. Add browser-level verification for theme switching and visual token application.
2. Add an automated font bundle-size check if the proposal budget is meant to be enforced continuously.

### Follow-up Tracking Issue Proposal

**Title**: Browser/runtime verification for design-system theme & bundle delta

**Scope**:
- add Playwright/browser verification for dark/light behavior across chat, dashboard, and docs
- add artifact-size checks for the new font bundle footprint
- document unrelated TypeScript blockers that still prevent a fully green workspace build

**Acceptance criteria**:
- `prefers-color-scheme` emulation proves dark and light token resolution in browser
- manual `data-theme="light"` and `data-theme="dark"` switching updates the rendered theme correctly
- Tailwind bridge utilities resolve correctly in both themes for chat and dashboard
- Starlight theme toggle applies Nothing token mappings correctly in docs
- bundle-size check compares before/after outputs and reports per-font delta, total delta, and pass/fail
- unrelated failures remain explicitly tracked for:
  - `clients/web/apps/chat/src/components/HealthIndicator.spec.ts:97`
  - `clients/web/apps/dashboard/src/components/sessions/SessionFilters.vue:33`

**Suggested commands**:
- `pnpm --dir clients/web --filter @corvus/chat run check`
- `pnpm --dir clients/web --filter @corvus/dashboard run check`
- `pnpm --dir clients/web --filter @corvus/docs run check`
- `pnpm --dir clients/web --filter @corvus/dashboard exec playwright test`
- `pnpm --dir clients/web install`
- `du -sh clients/web/node_modules/@fontsource-variable/space-grotesk/files`
- `du -sh clients/web/node_modules/@fontsource/space-mono/files`
- `du -sh clients/web/node_modules/@fontsource/doto/files`

**Artifacts / fixtures**:
- screenshots for light/dark chat, dashboard, and docs states
- screenshots for docs theme toggle before/after
- recorded bundle-size report attached to the verification output

**Pass/fail thresholds**:
- visual diffs must stay within agreed Playwright snapshot threshold for intentional theme changes
- no unexpected token regressions in rendered screenshots
- bundle delta must remain neutral or within the accepted budget defined by the proposal/spec

## Verdict

**PASS WITH WARNINGS**

The previously blocking design-system issues are resolved: dependency installation succeeds, old font dependencies were removed, docs and marketing builds now pass, reduced-motion rules include the required `!important` flags, and Button/Input now use the required micro transition duration. Remaining gaps are non-blocking and mostly about missing runtime/browser proof plus unrelated pre-existing TS build errors outside this change’s scope.
