/* ============================================================================
   AXIS SHARED TOP NAV  —  single source of truth for the master header.
   Injected by axis-nav.js on every subpage so the nav is IDENTICAL everywhere;
   only the active item (blue text + underline) changes per page.
   Solid-white palette (matches home, which runs its nav permanently scrolled).
   Self-contained: uses --axis-* vars with hard fallbacks so it works on any page.
