   Nav + Mobile Menu — canonical shared stylesheet.
   Sourced from the home page nav block. Loaded once per page via

   emitted by the _includes/partials/nav.njk partial.
   Depends on the site CSS custom properties (--deep-teal, --sage,
   --warm-cream, --dark-gray, --medium-gray, --card-radius) being
   defined on :root by the including page.
