Feature Request: Add Sound and Music Controls

[debugfest]

Some players prefer playing without sound or with their own music, but the game currently lacks audio control options. Without mute buttons, users may find the experience intrusive or distracting.

🎯 Proposed Solution

• Add sound and music toggles in the settings panel.
• Allow players to control separately:
  • Sound effects (e.g., merges, moves).
  • Background music (if available).
• Save preferences to local storage for persistence.

✅ Expected Behavior

• Players can mute/unmute sound effects and background music independently.
• Audio settings persist across sessions.
• No background audio plays after muting.

💻 Technical Notes

• Use HTML5 Audio API or Web Audio API for control.
• Implement volume and mute state management.
• Ensure accessibility: provide visual indicators for mute state.

🧪 Test Steps

1. Mute sound effects → verify no sounds play during moves.
2. Mute music → background audio stops.
3. Refresh page → preferences persist.
