   Tilecraft Digital — the Studio
   --------------------------------------------------------------------------
   The workspace is deliberately quiet. The storefront is loud on purpose;
   this is where people look at patterns, so the interface stays neutral and
   the two inks appear only as accents: a focus ring, an active marker, a
   confirmation. Everything else is paper and ink.

   Loaded after css/style.css, which carries the fonts, the color tokens,
   and the light and dark themes.
