/* Solitaire Collection — a card room that works by day or by night.
   ------------------------------------------------------------------
   Every colour is a token. The light palette is the default, the dark
   palette is redefined under prefers-color-scheme, and both are redefined
   again under [data-theme] so the in-app switch always wins. Components
   only ever reference tokens, never raw colours.                        */
