# T01: Added scale(1.02) hover to all 6 card types, cardEnter stagger animation across 5 pages, and gradient-border glow on featured technique

**Added scale(1.02) hover to all 6 card types, cardEnter stagger animation across 5 pages, and gradient-border glow on featured technique**

## What Happened

Added transform: scale(1.02) with will-change and smooth transitions to all 6 card types. Created @keyframes cardEnter and .card-stagger utility class with CSS custom property --stagger-index for staggered delays. Applied stagger indices across Home.tsx (nav-cards + recent), TopicsBrowse.tsx, CreatorDetail.tsx, SubTopicPage.tsx, and SearchResults.tsx. Redesigned .home-featured with gradient border-image and double box-shadow glow.

## Verification

npx tsc --noEmit passes. npm run build succeeds (50 modules). grep confirms cardEnter keyframe, card-stagger class, and stagger-index present in all 5 page components.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd frontend && npx tsc --noEmit` | 0 | ✅ pass | 3000ms |
| 2 | `cd frontend && npm run build` | 0 | ✅ pass | 3200ms |
| 3 | `grep -q 'cardEnter' frontend/src/App.css` | 0 | ✅ pass | 50ms |
| 4 | `grep -q 'card-stagger' frontend/src/App.css` | 0 | ✅ pass | 50ms |
| 5 | `grep -c 'stagger-index' (5 pages)` | 0 | ✅ pass | 50ms |


## Deviations

SearchResultCard needed staggerIndex prop threaded through. topic-card gained a new :hover rule (had none before).

## Known Issues

border-image removes border-radius on featured card — known CSS limitation. Glow box-shadow still provides visual treatment.
