- /watch live feed of active games with click-to-fullscreen and per-game back button - Starting a new game forfeits the in-progress game; opponent is flagged the winner - Watch CPU vs CPU self-play games; results shown for ~30s before cleanup - Detect threefold repetition in the C# rules layer and end the game as a draw Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
