Chess (live mode):
- Fetches opponent profile, shows real name in opponent bar
- Emotes sync to opponent via game_state (send + receive)
- Connection status monitored (green/yellow/red dot)
- Incoming emotes shown as floating animation
- mp.cleanup() on game end

Ludo (live mode):
- Emotes sync to opponent via ludo-match.php
- Connection status monitored
- Incoming emotes received and displayed

Both games:
- Fixed emoteWrap variable reference (was using wrong 'wrap')
- Shared multiplayer.js handles all common features
