/* ── Site header — shared by the tools app and the portal ─────────────────
   Markup: shared/templates/_site_header.html. Load AFTER brand.css (these
   rules consume its tokens) and after the app stylesheet, so the header wins
   over any page-local rule that reuses a class name like .nav-link.

   Every selector is scoped under .site-header. The old tools rules styled the
   BARE `header` element, which turned any <header> nested in a page into a
   second sticky 112px bar; scoping ends that. */
