/* Shared site header — the same on every public page, and floating: it
   stays with the visitor as they scroll.

   Loaded after each page's own <style>, and every rule is scoped to
   header.site-header, so it overrides the per-page copies of the header
   styles those pages still carry. site-nav.js holds the header's place in
   the page with a spacer (so making it fixed moves nothing) and adds
   .is-floating once the page has scrolled, when it settles into a compact
   frosted bar.

   Why fixed rather than sticky: every page wraps its content in the
   rounded .site-frame, which clips with overflow: hidden, and sticky
   positioning never escapes such a container. */
