 - **Image Proxy**: Added `/proxy/image` endpoint in backend with in-memory caching (24hr TTL, max 1000 images) to prevent YouTube CDN 429 rate limit errors. All avatars, badges, and emojis now route through proxy with stale-on-error fallback.
 - **Message Switching Animation**: Added smooth fade-out/fade-in transitions when switching between selected messages in overlay (300ms duration).
 - **Smart Message Preservation**: Implemented intelligent message trimming - regular chat messages limited to 200, but superchats and memberships preserved for entire session. Trimming happens on every message to prevent loss of special messages.
+- **Super Sticker Support**: Added full support for super sticker image display. Backend parser extracts sticker URL and accessibility label from `item.sticker` array in YouTube data. Added `stickerUrl` and `stickerAlt` fields to `SuperChatInfo` type. Image proxy whitelist updated to include `lh3.googleusercontent.com` domain. Dashboard and overlay both render super stickers with 144x144px max dimensions, centered layout, and graceful error handling that hides broken images. Protocol-relative URLs (`//domain.com`) are automatically converted to HTTPS.
+- **Task Master AI Integration**: Initialized Task Master AI with OpenRouter's x-ai/grok-code-fast-1 model for task management. Successfully completed Task 2 (Super Sticker Display) with 5 subtasks.
 
 ## Immediate Next Steps
-1. Test with live YouTube stream to verify badge parsing and superchat detection
-2. Add search/filter functionality for chat messages
-3. Implement error recovery and reconnection logic for stream interruptions
-4. Add keyboard shortcuts for quick message selection
-5. Consider persistent cache for images (SQLite or file-based) for better reliability
+1. Implement chat leaderboard badge support (Task 3)
+2. Add live poll display functionality (Task 4)
+3. Implement user authentication via YouTube OAuth 2.0 (Task 5)
+4. Consider persistent cache for images (SQLite or file-based) for better reliability
+5. Add error recovery and reconnection logic for stream interruptions
 
 ## Open Questions
 - Whether to add message search/filtering UI controls

 - **Image Proxy Pattern**: Backend `/proxy/image` endpoint caches YouTube CDN images (avatars, badges, emojis) with MD5-hashed keys, 24hr TTL, and 1000-image LRU eviction. Returns stale cache on 429 errors or network failures. Frontend `proxyImageUrl()` helper transparently rewrites YouTube CDN URLs to use proxy.
 - **Smart Message Storage**: Intelligent trimming system preserves all superchats and memberships for entire session while limiting regular messages to 200 most recent. Trimming occurs on every message addition to prevent special message loss. Uses order-preserving algorithm that identifies special messages by index and removes only oldest regular messages.
 - **Overlay Animation System**: Two-state approach with `message` (backend data) and `displayMessage` (UI state) enables smooth fade transitions when switching messages. 300ms fade-out followed by content swap and automatic fade-in.
+- **Super Sticker Parsing**: Backend `extractSuperChatInfo()` function detects super stickers via `item.sticker` array. Extracts largest image (144x144px) from sticker thumbnails array, handles protocol-relative URLs by converting to HTTPS, and captures accessibility labels for screen readers. Frontend conditionally renders stickers with error handling that hides broken images via `onError` handler.
