Karaoke Queue

Realtime system for managing queues in a karaoke, designed for multi-device environments.

> Description

Karaoke Queue is a backend-driven system for managing queues in a karaoke context. The architecture is designed to support multiple concurrent clients, real-time updates, and shared state consistency. The backend handles the entire application logic: queue synchronization, room management, client reconnection, and state persistence through Redis and MongoDB. The Expo client serves as a lightweight interface to demonstrate the system's real-time functionality.
