### In Campaign Levels

```javascript
// In your campaign level setup:
const tagManager = new MediaTagManager(window.game.dataManager);
const tagUI = new MediaTagUI(tagManager);
const campaignTagging = new CampaignTagging(tagManager, tagUI);

campaignTagging.initializeTaggingTask({
    requiredTags: ['outfit', 'pose'],
    requiredTagCount: 2,
    targetMediaIds: photoIds,
    onComplete: (progress) => {
        // Award points, complete level, etc.
    }
});

campaignTagging.displayTaggingInterface(container, mediaItems);
```

See `example-tagging-level.js` for complete working example.

## API Quick Reference

### MediaTagManager
```javascript
createTag(name, color)
deleteTag(tagId)
addTagsToMedia(mediaId, tagNames)
removeTagFromMedia(mediaId, tagId)
bulkAddTags(mediaIds, tagNames)

## Testing Checklist

- [ ] Create tags in tag management modal
- [ ] Tag individual photos in library
- [ ] Use bulk tagging to tag multiple photos
- [ ] Filter photos by tags (AND/OR modes)
- [ ] Rename and delete tags
- [ ] Check tag statistics
- [ ] Test autocomplete suggestions
- [ ] Verify data persistence (refresh page)

## Next Steps

To use the tagging system:

1. **Test in Library**: 
   - Open library.html
   - Capture some photos or load existing ones
   - Try tagging, filtering, and managing tags

2. **Create Campaign Level**:
   - Copy `example-tagging-level.js` as template
   - Customize requirements
   - Add to campaign data

3. **Extend Functionality** (Optional):
   - Add tag categories
   - Implement tag suggestions AI
   - Create tag-based collections
   - Add tag export/import UI

## Architecture

```
MediaTagManager (Core Data)
    ↓
MediaTagUI (UI Components)
    ↓
libraryTaggingIntegration (Library Integration)
    ↓
CampaignTagging (Campaign Integration)
```

All data flows through MediaTagManager, ensuring consistency.

## Performance

- Optimized for 1000+ photos/videos
- Efficient bulk operations
- Lazy rendering of tag lists
- Debounced autocomplete
- Minimal DOM manipulations

## Browser Compatibility

- Modern browsers (Chrome, Firefox, Edge, Safari)
- LocalStorage for persistence
- No external dependencies
- Responsive CSS Grid/Flexbox

## Support

For issues or questions:
1. Check docs/MEDIA_TAGGING_SYSTEM.md
2. Review example-tagging-level.js
3. Check browser console for errors
4. Verify DataManager is initialized
