/* ═══════════════════════════════════════════════════════════════
   Sidetake — site shell: tokens, grid, type, nav, buttons, panels,
   footer. The story sections live in story.css; the sign-up sheet
   in sheet.css.

   Structure and motion follow the reference Hemang chose (a single
   eased vertical story: framed hero, a list that fills as it scrolls,
   a pinned process scene, bands, giant counters, a dealt deck), with
   its colour roles mapped onto Sidetake's own:
     reference blue   → emerald  (the bold full-bleed blocks)
     reference orange → sage     (buttons, highlights, the "student")
     reference grey   → ink      (the page, under the same fine grid)
   Type stays Geist + Inter — hierarchy from weight and size only.
