/* One header for the whole site: static pages (src/components/SiteHeader.astro)

   this file, so the bar looks and behaves the same everywhere. Inside the forum
   a second row (.sh-sub) adds the community's own links.

   Everything is scoped to header.sh and sized in em from a fixed base, so neither
