📡 Zero Internet Required

WebSockets operate entirely over local area networks (LAN). Real-time race telemetry, chess moves, and chat never touch external cloud servers.

📱 Low-Cost Device Optimized

Engineered to run seamlessly on Android phones via Termux, $35 Raspberry Pis, or older refurbished classroom PCs with minimal memory footprint.

💾 Local SQLite Storage

Scores, user badges, talent metrics, and tournament brackets persist locally on the host device. Zero monthly cloud database bills.

⚡ Offline Service Worker PWA

Static assets, sounds, and UI stylesheets are locally cached via Service Worker, allowing instant offline startup.
