/* ---------------------------------------------------------------------------
   Spieltisch.

   Every value in the token block is the one the chess app already uses
   (stacks/chess/app/public/style.css). The platform does not invent a second
   language: it lifts the one that exists into a shared file, and each game
   draws with it. New here are only the three parts chess never needed -- chat
   bubble, seat, die -- and they are built from the same pieces.

   Three theme blocks, as over there: the light default, the system preference,
   and the forced choice. A colour whose only definition sits inside a media
   query has no value when the user forces the other theme.
