+Then set this package's version in `startos/versions/current.ts` to **the same number**, as

+submodule tag exactly, so v0.5.3 becomes `0.5.3:0`. Give it release notes naming what changed for

 `CHANGELOG.md` and `docs/architecture/multiplayer.md`), read it before bumping: a running

+The front page offers solitaire, the replay viewer, and multiplayer. **Play multiplayer** takes you
+to the lobby: create or join a game, seat players (including filling empty seats with a bot), and
+start. Once a game is underway, this same interface is where every player plays their turns and
+watches the table — there is nothing else to open.
+
+Solitaire runs entirely in your own browser and needs nothing from the server, so it works here
+exactly as it does on the public Station Master site.
