|
||
|
|
- Added stardust CSS particles on .falling-letter--dissolve via ::before/::after pseudo-elements with box-shadow sparkle
|
||
|
|
- Added companion-float animation for gentle avatar bobbing
|
||
|
|
- Added prefers-reduced-motion media query disabling all animations
|
||
|
|
- Added responsive styles at 700px (smaller keys, scaled fonts, adjusted grids)
|
||
|
|
- Added global error handler catching uncaught exceptions with kindgerechtes overlay
|
||
|
|
|

|
|
## Task Commits
|
||
|
|
|
||
|
|
Each task was committed atomically:
|
||
|
|
|
||
|
|
1. **Task 1: Enhanced CSS animations + responsive layout** - `3a79379` (feat)
|
||
|
|
2. **Task 2: Global error handler + error overlay** - `f3cb948` (feat)
|
||
|
|
|
||
|
|
## Files Created/Modified
|
||
|
|
- `src/styles/main.css` - Leaf-fall, stardust, companion-float keyframes; error overlay styles; reduced-motion + responsive media queries
|
||
|
|
- `src/main.ts` - Global error + unhandledrejection event listeners
|
||
|
|
- `index.html` - Error overlay div with tree icon, message, and reload button
|
||
|
|
|
||
|
|
## Decisions Made
|
||
|
|
- Stardust particles use box-shadow on pseudo-elements for 6 total sparkle points (efficient, pure CSS)
|
||
|
|
- Error overlay uses tree emoji and German child-friendly message ("Oh, der Wald braucht kurz eine Pause...")
|
||
|
|
|
||
|
|
## Deviations from Plan
|
||
|
|
|
||
|
|
None - plan executed exactly as written.
|
||
|
|
|
||
|
|
## Issues Encountered
|
||
|
|
None
|
||
|
|
|
||
|
|
## User Setup Required
|
||
|
|
None - no external service configuration required.
|
||
|
|
|
||
|
|
## Next Phase Readiness
|
||
|
|
- All visual polish complete (animations, responsive, error handling)
|
||
|
|
- Ready for remaining Phase 04 plans (audio, export/import)
