When the card sequence is correct, a countdown timer now starts:
- Shows 3, 2, 1 in the submit button (1.5s per number)
- Auto-submits the solution when countdown reaches 0
- Countdown resets if sequence becomes imperfect
- Countdown disabled for spectators
This provides:
- Visual feedback that the sequence is correct
- Automatic submission without requiring a click
- Time for players to review before submission
- Smooth game flow when solving perfectly
Implementation:
- perfectCountdown state tracks current number (3, 2, 1, or null)
- First useEffect starts/resets countdown based on isSequenceCorrect
- Second useEffect decrements countdown every 1.5s and auto-submits at 0
- Button displays countdown number when active, otherwise shows checkmark
