/* Kestrel Exams: the one site header (navy bar), shared by every page since 2026-10-19.
   Built from the header rules in site.css, with every selector scoped to header.site so it wins over
   guide.css and the legal pages' inline styles. Subjects menu rules are at the end.
   Loaded on every non-app page AFTER the page's own stylesheet. */
