- Deal the hands from the shuffled stack and draw the trump card from it, so the trump card is in nobody's hand and cannot be played - A wizard or jester as trump card means no trump suit (previously a wizard let the dealer choose); remove the trump selection phase, the ChooseTrump action, the trump picker UI and the AI trump actions - Completed tricks carry their round's trump card, so the table keeps showing the matching trump card while the last trick of a round is displayed - Card corners are no longer rotated, so 6 and 9 cannot be confused - Trump label explains why there is no trump (wizard, jester, last round) - Tests: trump card never dealt, special cards give no trump, tricks keep their trump card Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
