   MAIN / GLOBAL stylesheet.

   This file holds the foundation every section depends on:
   design tokens (:root), reset, base typography, buttons, the
   shared .section utilities and the .reveal animation.

   Per-section styles live in their own files and are linked
   after this one in base.html:
     header.css · hero.css · stats.css · about.css · approach.css
     credentials.css · manifesto.css · partner.css · contact.css
     footer.css · responsive.css (last, for media-query overrides)
