/* ── demo.css — the Samatva frame around the dashboard ─────────────────
   The bar, drawer and tour belong to the studio, not to the product, so
   they speak the site's language: void ground, chrome type, DM Mono for
   the machine voice, Instrument Serif for the human one, and the two
   accents (cool / warm) only ever as light — hairlines and glows. The
   dashboard underneath keeps its own look, because it is the product.
   Every token is prefixed --s- so nothing leaks into the dashboard. */
