   Prefer returning a fixed known count for the game's static layout and
   letting dynamic content fill it, rather than inferring the count.
+- The client refuses to start below 80x24 (`terminal_too_small`). Every game
+  board must fit in that size; a new board wider or taller than the minimum
+  must raise the minimum in the same change.
+

+  current shape; a schema change means deleting `server.db` and `client.db`.
+  Files written by an older build are not supported.
