/* ============================================================
   MomokoArt design tokens
   ------------------------------------------------------------
   Shipped dormant: nothing consumes these yet, so this file
   cannot change a single pixel — a custom property renders
   nothing until some rule var()s it, and there are no other
   rules here. Page stylesheets begin adopting these in later
   phases. Values mirror the current homepage palette so that
   adoption stays visually neutral.

   Naming is unified on --momokoart-* (matching the plugin dir,
   the PHP prefix, and five of six body classes; the homepage's
   older --momoko-home-* set is the outlier and is migrated over
   time, not touched here).
