/* base.css — the platform's base sheet: the primitives every module's pages are built from
   (a page head, a button, a card, a form, a badge, the date field), drawn ONLY in the site's
   tokens. A page links it BEFORE the site's /styles.css, so the site's tokens and rules win.

   The contract a site fulfils is four tokens — --bg, --text, --accent, --font — declared in
   its styles.css; everything else below has a default derived from those four, and a site
   overrides any of them by declaring it. See docs/WEBSITE.md, "The contract". */
