1// Try a room locally: node src/try-room.mjs [seed]. Starts referee/room.mjs with a scripted person at seat 0 and a
2// scripted agent at seat 1 (both play like the starter bot), the field and auto at the others, and prints every
3// @shoal line, shortened. On the way it hands seat 0 to an agent and sends one move with the old version (the room
4// drops it), lets seat 1 miss its time limit once (auto plays), then hands seat 1 back to auto.
