   Universal page top-spacing system (SINGLE SOURCE OF TRUTH).

   The .site-header is position: fixed and overlays the viewport, so
   every <main> must clear the full header. We split behavior into
   two cases:

   1. Homepage (body.home main)
      Must be flush under the navbar (NO visible gap). We reserve
      exactly --header-height so the hero's own padding-top provides
      the internal breathing space.

   2. All other pages
      Must never hide the page eyebrow/header under the navbar. We
      reserve --page-top-offset (= --header-height + breathing room).

   Every page-specific .X-main class (docs-main, playground-main,
   etc.) inherits this value. They MUST only override padding-bottom,
   never padding-top, and MUST NOT use shorthand `padding: X Y` that
   would clobber the rule.
