/* Universal site header (see site-header.js), styled to match the dashboard
   chrome: a 56px bar with a bottom border, bordered square controls, and a
   hamburger menu holding every site link grouped and fully expanded.
   Self-contained: private tokens (not the host page's own --background /
   --foreground vars) drive the navigation chrome, but site-header.js still
   stamps html.light / html.dark on every page, and the light-mode block
   below repoints those private tokens so the header follows the visitor's
   chosen theme instead of staying dark forever. */
