/* ═══════════════════════════════════════════════════════════════
   The Upgrade (upgrade.html)
   Self-contained on purpose. upgrade.html loads css/fonts.css and
   this file, nothing else, so every token and every shared part
   (nav, buttons, hero, footer, back-to-top) is mirrored here the
   way css/grants.css and css/store.css mirror them. If the palette
   in css/style.css changes, update this file, css/grants.css,
   css/store.css and css/terms.css together.

   Art direction is the grants page with the volume turned down
   again. This is a page somebody reads all the way through and
   then fills in a long form at the bottom, so the loudest object
   on it is a field label, not a card. The numbered sections are
   the terms document's; the fields are the store drawer's, grown
   up from one phone box into a real form. Nothing here animates
   except the hero, because a form that moves while you type is a
   form people abandon.
