/* ===== SHARED SITE HEADER =====
   One source of truth for the slim header used by index.html and order.html.
   Constant height (no shrink-on-scroll); assets/header.js measures it into
   --header-h so sticky offsets (order page) stay exact, including the wrapped
   mobile layout.

   Relies on tokens defined by the host page: --sage --red --cream --body-font.
   Nav uses brand --red; the host page lightens --sage so red clears the 3:1
   large-text/UI contrast bar.

   Layout: logo left, nav right (flex space-between) — the conventional pattern,
   robust at every width instead of centering + absolute positioning. */
