- Configure VitePWA with manifest, icons and service worker
- Add PwaInstallBanner component for install prompt in header
- Enable CORS for z590.interno.com access
- Use dynamic hostname for terminal WebSocket connection
- Add generate-icons script with sharp for PWA icons
- Fix theme-color to match header background
Split monolithic index.ts (~1400 lines) into modular structure:
- config.ts: Server configuration and constants
- db/: Database initialization, migrations, and seeds
- routes/: API handlers by domain (themes, canvas, components, etc.)
- services/: Terminal WebSocket server
- utils/: CORS helpers
Entry point now only coordinates initialization.
