Building the Play Screen

Once the player chooses a topic, the game requires a play screen where the real action takes place. This is the heart of the memory challenge, with all the cards laid out for matching.

On the play screen, you'll:

1. Show a friendly header and a small label with the chosen topic;
2. Display a centered board with 20 cards (10 matching pairs) based on that topic's emojis;
3. Start with all cards face-down;
4. Add smooth 3D flip animations when a card is tapped;
5. Keep gameplay logic simple:
   • If two flipped cards match → they stay open;
   • If they don't match → they flip back after a short delay;
   • While two cards are being checked, no other cards can flip.
