    /* ---------- Z-index scale (v8.0.0) ----------------------------------
       One shared scale for every layered/fixed element on the site, so
       stacking order is predictable no matter which stylesheet an element
       lives in. Higher number = sits on top. Previously the mobile nav
       drawer had no z-index of its own and could end up hidden behind
       other fixed/positioned page content (e.g. the back-to-top button);
       giving every layer an explicit, documented slot here fixes that.
         --z-content        content-layer decorative bits (hero overlay,
                             page-banner, breadcrumbs) — effectively "0"
         --z-back-to-top    the floating back-to-top button
         --z-navbar         the sticky/fixed site navbar
         --z-mobile-drawer  the mobile slide-in nav drawer (.nav-links)
         --z-mobile-toggle  the hamburger/X button that opens/closes it
         --z-skip-link      the accessibility "skip to content" link
