The store plays any seat, locally against the bot or remotely through the server. A room has a four-letter code that is also its invite link; the hall opens or joins one and lists the seats this browser holds with whose move it is. The ledger and summary show every seat, threats name their wizard, and the board is one component shared by the hall and the room page. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
