Implemented display of country flags and competitor numbers in event chat messages: - Country flags displayed as emoji (🇸🇪, 🇵🇱, etc.) with proper emoji font support - Competitor numbers shown in #123 format next to usernames - Normalized data architecture with user and participant caches on frontend - User data (username, avatar, country) and participant data (competitorNumber) cached separately - Messages store only core data (id, content, userId, createdAt) - Prevents data inconsistency when users update profile information - Fixed duplicate message keys React warning with deduplication logic - Backend sends nested user/participant objects for cache population - Auto-updates across all messages when user changes avatar or country Backend changes: - Socket.IO event_message and message_history include nested user/participant data - API /events/:slug/messages endpoint restructured with same nested format - Batch lookup of competitor numbers for efficiency Frontend changes: - useEventChat hook maintains userCache and participantCache - ChatMessage component accepts separate user/participant props - ChatMessageList performs cache lookups during render - Emoji font family support for cross-platform flag rendering
