1// The viewer: wmzy/sanguosha's engine views and action building, drawn as 无名杀 draws a 三国杀 table (noname/Table.tsx),
2// fed by Shoal instead of the upstream's server. Replay mode plays a replay file from referee/ (the upstream format,
3// sanguosha-replay v2) with the upstream's replay hook. Live mode (?live) gets a room's messages through bridge.js,
4// keeps the public view and the controlled seats' own views up to date with the upstream client's own view maintainer,
5// and posts the seat's moves back with shoalAct.
