# T02: Add CSS page-enter fade-in transitions to all pages

Add a subtle CSS-only fade-in animation that triggers when page components mount. No libraries needed — a @keyframes animation applied to page wrapper elements.

Steps:
1. In `frontend/src/App.css`, add a `@keyframes pageEnter` animation: opacity 0→1 and translateY(8px→0) over 250ms ease-out.
2. Add a `.page-enter` class that applies this animation.
3. Apply the `.page-enter` class to the outermost wrapper div in each page component:
   - `SubTopicPage.tsx` — the `.subtopic-page` div
   - `SearchResults.tsx` — the `.search-results-page` div
   - `TopicsBrowse.tsx` — its outermost wrapper
   - `CreatorsBrowse.tsx` — its outermost wrapper
   - `CreatorDetail.tsx` — its outermost wrapper
   - `TechniquePage.tsx` — its outermost wrapper
   - `Home.tsx` — its outermost wrapper
4. Alternative to adding className to every page: apply the animation directly to existing page container classes in CSS (e.g., `.subtopic-page, .search-results-page, .topics-browse, ...  { animation: pageEnter 250ms ease-out; }`). This avoids touching every TSX file. Choose whichever approach is cleaner given the existing class names.
5. Verify: `cd frontend && npx tsc --noEmit && npm run build`

## Inputs

- `frontend/src/App.css`
- `frontend/src/pages/SubTopicPage.tsx`
- `frontend/src/pages/SearchResults.tsx`
- `frontend/src/pages/TopicsBrowse.tsx`
- `frontend/src/pages/CreatorsBrowse.tsx`
- `frontend/src/pages/CreatorDetail.tsx`
- `frontend/src/pages/TechniquePage.tsx`
- `frontend/src/pages/Home.tsx`

## Expected Output

- `frontend/src/App.css`

## Verification

cd frontend && npx tsc --noEmit && npm run build
