- Three full-screen rotating views: Network Topology (D3.js),
  Kanban Board (Odoo tasks), Calendar (Odoo events)
- Hooks for data fetching, WebSocket, and view rotation
- Header with live clock and connection status
- Framer Motion fade transitions between views
- Docker Compose with backend (host network for nmap) and
  frontend (nginx proxy to backend API/WS)
