/* What a game offers, wherever it is shown (src/core/offer.ts, src/gate/): the
   three actions (Play, Download, Remix), the download panel's tiles, the rows
   of remixes, and the dialogs over a page: the panel, every version, the
   sign-in card, the membership, the remix prompt.

   The landing page, a game's page and the play page's dock on a game's own
   host all load this file (the build copies it to /play/gate.css), so it
   brings its own colours and faces and leans on no other stylesheet. */
