Duels between people: rooms, the hall, and a games ledger

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.
