-- [ ] **T02: Add React.lazy code splitting for admin and creator dashboard pages** — ## Description
+- [x] **T02: Replaced 6 static page imports with React.lazy + Suspense in App.tsx, producing 7 JS chunks from the previous monolithic bundle** — ## Description
All 17 page components are eagerly imported in `App.tsx`. Wrap admin and creator pages in `React.lazy()` + `Suspense` so they load on-demand, reducing initial bundle size.

+
+**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
+
