- Create screen: choose キャッシュオンリー (real cards, chips only), 友人戦
(server deals and settles) or CPU戦 (友人戦 plus 1–8 CPU players); replaces
the card toggle. The lobby shows each table's type
- Poker AI written from scratch (server/ai.js, no libraries): fast 7-card
evaluator (checked against bestHand), Monte Carlo equity, and decisions from
hand rank, pot odds, raise count, opponents and a per-CPU style (aggression,
bluff rate); continuation bets via the last aggressor. It never sees other
players' hole cards
- CPU seats: think time of 0.7–1.8s (faster when no human is left in the hand),
automatic rebuy, never the host, no new hand unless a human is playing,
re-think after pause
- Play UI: robot avatars and a "考えています…" status for CPU turns
- Tests for the evaluator, equity, legality of AI actions and CPU tables
