board.set('shapes', board.get('shapes').add({
  id: 'square-1', 
  type: 'square',

}));

// Both users add different tags simultaneously
// User A: board.set('tags', board.get('tags').add('urgent'));
// User B: board.set('tags', board.get('tags').add('design'));

// When they sync:
// ✅ Both shapes appear - no overwrites
// ✅ Both tags are present: Set {'urgent', 'design'}
// ✅ Cursor positions update in real-time via the map
// ✅ No conflict dialogs - additions always win

// The magic: Sets and maps merge like Git branches - intelligently combining changes.
// Unlike last-write-wins, everyone's additions are preserved.
