/* ────────────────────────────────────────────────────────────────
   GameOS — shared styles for the standard-scroll content pages
   (/about, /customers, /changelog, /vs/*).

   index.html and features.html each carry their own inline <style>
   block and do NOT load this file. This exists so the pages added
   after them share one stylesheet instead of copying the base four
   more times. The :root tokens below are copied verbatim from
   features.html — if the brand palette moves, move it in all three.
