/* Shared professional site header - used on every page across every site. Purely structural - no
   color values live here; each site's own site.css defines --site-dark/--site-dark-2/--site-light/
   --site-accent, which this file references via var(). Union of every site's header features
   (brand logo image, Services dropdown, mode-toggle button) - a site's HTML simply won't have the
   elements for features it doesn't use, so the unused rules here are harmless. Load this AFTER
   that site's own site.css, which must define --site-dark/--site-dark-2/--site-light/
   --site-accent - this file only ever reads them via var(), never defines them. */
