/* Pond & Paper: the studio's design tokens, one file for the site and any game
   that wants them (docs/plans/site-redesign-2026-10-24.md, section 2).
   Copied to /theme.css by scripts/build-site.mjs and linked before site.css.
   Every name starts with --dl- so nothing collides with a game's own variables.
   Colour pairs are contrast-checked in the plan (section 2.2); a new colour needs
   a measured pair before it goes in. site/sitebar.css repeats the few values it
   needs (it must stand alone inside a game); src/theme.test.mjs keeps them equal. */
