/* TaiChan Games Board — multiplayer lobby.
   Builds only on the shell.css design tokens and classes (.btn, .status,
   .game-header). Everything here is prefixed .lobby- to stay out of the way of
   the shared shell and the game pages. Also defines .cat-avatar, since the lobby
   is the first page to render avatars and does not load multiplayer.css. */
