/* public/pages.css
   The content pages: how to play, terms, privacy, status.

   These are documents, not the playfield. style.css is deliberately not loaded
   here — it locks the body to the viewport with `overflow: hidden`, disables
   text selection and kills `touch-action`, all correct for a canvas game and
   all wrong for something you read and scroll. Tokens come from tokens.css so
   the two surfaces still share one palette. */
