-## Implementation Overview
-
-* **Multi-game scoping**: Each game has isolated lobbies via Game ID
-* **Real-time WebSocket events**: member join/leave, ready status, lobby data updates
-* **Custom lobby properties**: Store arbitrary key-value data per lobby
-* **Built-in stats**: Global & per-game player/lobby counts
-* **Rate limiting**: Protects against abuse by default
-* **Web dashboard + Swagger**: Monitor lobbies and test API
-
