   Used by every standalone guide article (/guide/<slug>/index.html) and
   the guide hub (/guide/index.html). This is the reusable template's
   single stylesheet — when creating a new article, copy an existing
   article's index.html, link this same file, and follow its class
   conventions (page-hero, prose, steps, bullets, callout, related-grid).
