/* The home page's header on every other website page (Charlie, 18 Oct 2026:
   the new menu on every page; owner, 19 Oct: the other pages still showed the
   old header). web/index.html is the source: its <header> is copied into each
   page by tools/sync_site_header.py, and these rules are its header rules.
   Every rule is scoped to body > header.site-header so it outranks style.css
   (body > header, nav, nav a, .btn) and each page's own styles, and touches
   nothing else on the page. tests/test_site_header.py. */
