# T02: Replaced 6 static page imports with React.lazy + Suspense in App.tsx, producing 7 JS chunks from the previous monolithic bundle

**Replaced 6 static page imports with React.lazy + Suspense in App.tsx, producing 7 JS chunks from the previous monolithic bundle**

## What Happened

Converted AdminPipeline, AdminTechniquePages, AdminReports, CreatorDashboard, CreatorSettings, and About from static imports to React.lazy() dynamic imports. Added LoadingFallback component and individual Suspense wrappers per lazy route. ProtectedRoute wraps Suspense for creator routes so auth guard fires before chunk load. Core public and auth pages remain eagerly imported.

## Verification

npm run build exits 0 producing 7 JS chunks. rg confirms 6 React.lazy imports. All slice-level checks pass: no public-client references, api/index.ts and client.ts exist, 11 API module files.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npm run build` | 0 | ✅ pass | 6400ms |
| 2 | `ls frontend/dist/assets/*.js | wc -l` | 0 | ✅ pass (7 files) | 100ms |
| 3 | `rg 'React.lazy' frontend/src/App.tsx` | 0 | ✅ pass (6 matches) | 100ms |
| 4 | `rg 'public-client' frontend/src/ -g '*.ts' -g '*.tsx'` | 1 | ✅ pass (no matches) | 100ms |
| 5 | `test -f frontend/src/api/index.ts && test -f frontend/src/api/client.ts` | 0 | ✅ pass | 50ms |
| 6 | `ls frontend/src/api/*.ts | wc -l` | 0 | ✅ pass (11 files) | 50ms |
