- Replace ShaderGradientBackground WebGL shader (3 static spheres) with pure CSS radial-gradient divs — moves from ClientProviders (deferred JS) to app/layout.tsx as a server component rendered in initial HTML. Eliminates @shadergradient/react, three, @react-three/fiber from the JS bundle. Removes chunks/7001 (~20s CPU eval) and the 39s main thread block. - Remove optimizeCss/critters: it was converting <link rel="stylesheet"> to a JS-deferred preload, which PageSpeed read as a 410ms sequential CSS chain. Both CSS files now load as parallel <link> tags from initial HTML (~150ms). - Update browserslist safari >= 15 → 15.4 (Array.prototype.at, Object.hasOwn are native in 15.4+; eliminates unnecessary SWC compatibility transforms). - Delete orphaned app/styles/ghostContent.css (never imported anywhere, 3.7KB). - Add .claude/ dev team setup: 5 subagents (frontend-dev, backend-dev, tester, code-reviewer, debugger), 3 skills (/add-section, /review-changes, /check-quality), 3 path-scoped rules, settings.json with auto-lint hook. - Update CLAUDE.md with server/client orchestrator pattern, SSR animation safety rules, API route conventions, and improved command reference.

Testing Rules
Jest environment
- Global mocks are set up in
jest.setup.ts— do NOT re-mockmatchMedia,IntersectionObserver, orNextResponsein individual tests - Test env vars are pre-set:
DIRECTUS_URL,NEXT_PUBLIC_SITE_URL - Always mock external API calls (Directus, n8n, PostgreSQL) — tests must work without running services
ESM modules
If a new import causes "Must use import to load ES Module" errors, add the package to transformIgnorePatterns in jest.config.ts.
Server component tests
// Server components return JSX, not a promise in React 19, but async ones need await
const resolved = await MyServerComponent({ locale: 'en', ...props })
render(resolved)
next/image in tests
Replace next/image with a plain <img> in test renders:
// eslint-disable-next-line @next/next/no-img-element
<img src={src} alt={alt} />
Run commands
- Single file:
npx jest path/to/test.tsx - All unit tests:
npm run test - Watch mode:
npm run test:watch - Specific E2E:
npm run test:critical,npm run test:hydration,npm run test:accessibility
