Add optional card mode: server deals cards and settles showdowns automatically
- New "カードを配る" switch on the create-table screen (default off); the lobby shows "カードあり" for tables that use it - Card mode (server/cards.js restored): crypto-shuffled deck kept server-side, hole cards sent only to their owner until showdown/all-in reveal, board dealt per street with burns, all-in runout on a timer (frozen while paused) - Showdown is evaluated and every pot (incl. side pots, split pots) is paid out automatically; host winner selection is only used when card mode is off - Play UI: board, hole cards, own cards in the action bar, hand names, winning cards highlighted; layout tuned for 7+ seats and short screens - Playing-card styles use .pcard so they don't clash with the existing .card panel - Tests for hand evaluation, card privacy, runout, side pots, ties and random play Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
