- **Selection State Management**: Three-tier visual state system (active/selected, normal, previously-selected) with CSS class composition for clear user feedback.
- **Timestamp Resolution**: Backend uses `timestamp_usec` (microseconds) from YouTube data, converts to milliseconds, and frontend formats in user's local timezone.
- **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.
