Restructure the monolithic 252-line main.rs into a 10-crate workspace with clean hexagonal architecture, swappable adapters, and a production- ready deployment pipeline. Backend architecture: - domain: Canvas, Color/Position/PixelUpdate value objects, port traits (CanvasStore, CanvasPersistence, EventBroadcaster), BroadcastEvent - application: use cases (place_pixel, get_state, save/restore snapshot, connect/disconnect), AppState with Arc snapshot cache - config: AppConfig structs + ConfigSource trait - api-types: shared DTOs, event name constants - adapters: config-env, canvas-file, http-axum (rust-embed), socketio, websocket — all behind port traits, swappable via feature flags - server: composition root with graceful shutdown (SIGTERM/SIGINT) Frontend: - Transport abstraction: Socket.IO and native WebSocket via VITE_TRANSPORT - Canvas zoom/pan with mouse wheel, pinch-to-zoom, and +/- buttons - ImageData rendering (~50x faster than fillRect loop) - Touch support, responsive CSS scaling, mobile-friendly layout - OG/Twitter Card meta tags for rich link previews Production: - Docker: musl static build on scratch — 2.73MB image - CI workflows for Gitea and GitHub Actions (fmt, clippy, test, Docker push) - deploy.sh for private registry - 39 unit tests across domain and application - Zero unwraps, zero unsafe, graceful error handling with tracing - Periodic canvas snapshots with rotation, restored on startup - All config via environment variables with typed defaults
