## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Replaced eslint.config.ts with eslint.config.mjs**
- **Found during:** Task 2
- **Issue:** Old Vue 3 eslint.config.ts used @vue/eslint-config-typescript which is incompatible with @nuxt/eslint ESLint 10 flat config
- **Fix:** Deleted eslint.config.ts, created eslint.config.mjs importing from .nuxt/eslint.config.mjs
- **Files modified:** eslint.config.ts (deleted), eslint.config.mjs (created)
- **Commit:** c4923a0

**2. [Rule 3 - Blocking] pnpm build scripts approval**
- **Found during:** Task 1
- **Issue:** pnpm blocked native dependency build scripts (esbuild, sharp, etc.)
- **Fix:** Added pnpm.onlyBuiltDependencies to package.json
- **Files modified:** package.json
- **Commit:** 9fbbce0

## Known Stubs

None - this is a foundation plan with minimal UI (placeholder index page only, intentional).

## Self-Check: PASSED
