N-player (2-8) real-time Snake game alongside Connect 4. Lobby has tabs to switch between games. Players join via invite link with 10-second countdown. Game loop runs at tick-based intervals with NATS pub/sub for state sync. Keyboard input not yet working (Datastar keydown binding issue still under investigation).
