/* site.css — the shared design system for the marketing pages
   (index, icp, check). Tokens, reset, typography, .wrap, .btn, nav and footer.

   Anything a single page needs lives in its own sheet next to this one and is
   loaded after it, so a page rule always wins. The three pages were authored
   separately and drifted; only what is byte-identical in all three is here.
