perf: eliminate Three.js/WebGL, fix render-blocking CSS, add dev team agents
- 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.

Component Rules

SSR animation safety (critical)

Never use initial={{ opacity: 0 }} on server-rendered elements. This bakes style="opacity:0" into HTML — content is invisible if hydration fails.

Use ScrollFadeIn instead:

import ScrollFadeIn from "@/app/components/ScrollFadeIn"
<ScrollFadeIn><MyComponent /></ScrollFadeIn>

AnimatePresence is fine for modals and overlays that only appear after user interaction.

Design system

  • Colors: only liquid-* tokens — no hardcoded hex or raw Tailwind palette colors
  • Cards: bg-gradient-to-br from-liquid-*/15 via-liquid-*/10 to-liquid-*/15 backdrop-blur-sm border-2 rounded-xl
  • Headlines: uppercase tracking-tighter with accent dot <span className="text-emerald-600">.</span>
  • Body text: text-stone-600 dark:text-stone-400 — never text-stone-400 alone (fails contrast)

Async components

Every component that fetches data must have a Skeleton loading state shown while data loads.

i18n

  • Client: useTranslations("namespace") from next-intl
  • Server: getTranslations("namespace") from next-intl/server
  • New client sections need a wrapper in ClientWrappers.tsx with scoped NextIntlClientProvider

TypeScript

  • No any — define interfaces in lib/directus.ts or types/
  • No emojis in code
