   The token names and values mirror www/css/style.css and www/js/themes.js
   so the page reads as the same product. Six themes live on [data-theme];
   demo.js reads --pal-* for the board colours, so the palette has exactly
   one source of truth: this file.

  /* Accent colours are tuned to sit on the board, not to be read as small
     text — on the light Candy theme the raw accent falls under 3:1. Blending
     towards --text darkens it on light themes and lightens it on dark ones,

     override of --accent/--text automatically re-resolves this too. */
