/* =========================================================================
   LUMINAGE — SHARED NAVBAR
   =========================================================================
   The one navbar, used byevery page. Self-contained: it does not depend on
   any page's own styles, so it looks identical everywhere.

   To put it on a new page:
     1. <link href="assets/css/nav.css" rel="stylesheet">   (../assets/… in /pages)
     2. Paste the <nav class="site-nav"> block from any existing page
     3. <script src="assets/js/nav.js"></script>            (after cart-ui.js)

   Sticky rather than fixed, so it never overlaps the top of a page and no
   page needs padding to compensate.
