## Task Commits
|
||
|
|
|
||
|
|
Each task was committed atomically:
|
||
|
|
|
||
|
|
1. **Task 1: HTML Daten-Section + Export/Import/Reset buttons** - `5396dc0` (feat)
|
||
|
|
2. **Task 2: Export/Import/Reset logic in parent.ts** - `7931f7e` (feat)
|
||
|
|
|
||
|
|
## Files Created/Modified
|
||
|
|
- `index.html` - Added Daten section with export/import/reset buttons and hidden file input
|
||
|
|
- `src/styles/main.css` - Added styles for action buttons including danger variant
|
||
|
|
- `src/ui/parent.ts` - Added exportData, importData, resetAllData functions with button wiring

|
||
|
|
## Decisions Made
|
||
|
|
- Export excludes Blobs (only progress+settings) for JSON portability and small file size
|
||
|
|
- Import validates required fields (currentLevel, completedLevels, totalSessions, selectedCharacter, selectedLayout, audioEnabled) before prompting overwrite
|
||
|
|
- Reset clears all 5 stores (progress, companionAssets, styleReference, forestElements, settings) then reloads
|
||
|
|
|
||
|
|
