- 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.

requestIdleCallback is unavailable in Safari < 16.4, causing GatedProviders
to crash during hydration and blank the entire page. Added setTimeout fallback.
Also added IntersectionObserver fallback in ScrollFadeIn for safety.

- Remove framer-motion from Hero.tsx and HeaderClient.tsx, replace with CSS animations/transitions
- Replace lucide-react icons (Menu, X, Mail) with inline SVGs in HeaderClient.tsx
- Lazy-load About, Projects, Contact, Footer via dynamic() imports in ClientWrappers.tsx
- Defer ShaderGradient/BackgroundBlobs loading via requestIdleCallback in ClientProviders.tsx
- Remove AnimatePresence page wrapper that caused full re-renders
- Enable experimental.optimizeCss (critters) for critical CSS inlining
- Add fadeIn keyframe to Tailwind config for CSS-based animations
Homepage JS reduced from 563KB to 438KB (-125KB).
Eliminates ~39s main thread work from WebGL init and layout thrashing.

- Add WebGL support detection in ShaderGradientBackground to prevent console errors
- Add .catch() fallback to ShaderGradientBackground dynamic import
- Remove hardcoded aria-label from consent banner minimize button (fixes label-content-name-mismatch)
- Use rewrite instead of redirect for root locale routing (eliminates one redirect hop)
- Change n8n API cache headers from no-store to no-cache (enables bfcache)
- Add three and @react-three/fiber to optimizePackageImports for better tree-shaking

- Add `prefix` param to checkRateLimit/getRateLimitHeaders so each endpoint
has its own bucket (previously all shared `admin_${ip}`, causing 429s when
analytics/track incremented past n8n endpoints' lower limits)
- n8n/hardcover/currently-reading → prefix 'n8n-reading'
- n8n/status → prefix 'n8n-status'
- analytics/track → prefix 'analytics-track'
- Remove custom analytics system (AnalyticsProvider, lib/analytics,
lib/useWebVitals, all /api/analytics/* routes) — was causing 500s in
production due to missing PostgreSQL PageView table
- Remove analytics consent toggle from ConsentBanner/ConsentProvider

Move ConsentBanner rendering into the locale layout so next-intl context is always available (prevents missing provider errors).
fix(activity-feed): use dark styling for disabled state
Avoid white disabled cards so the feed never appears as a white/transparent block after reload.
test(e2e): assert nav text changes on locale switch
Strengthen i18n test to verify translated labels.
