Before writing Next.js code

1. Read docs/agent/architecture/nextjs-critical-fixes.md for full patterns
2. Check existing components in apps/frontend/components/ for examples

Critical Rules (always apply)

Waterfalls

• Use Promise.all() for independent fetches
• Wrap slow data in <Suspense> boundaries
• Defer await into branches where needed

Bundle Size

• NO barrel imports: import X from 'lucide-react' ❌
• YES direct imports: import X from 'lucide-react/dist/esm/icons/x' ✅
• Use next/dynamic for heavy components (editors, charts, PDF viewers)
• Defer analytics with ssr: false
