   Header
   --------------------------------------------------------------------------
   Sticky at the top with a transparent background. Each menu link sits on its
   own frosted-glass pill (blur + translucent tint of the colour behind it), and
   text, hover and button colours follow that colour (`data-header-theme` and
   `--header-bg` on <html>, set by js/modules/section-colors.js), so the menu
   stays readable over any content.
   Without JavaScript it keeps the solid red background.
