/* ============================================================
   NAV — shared component
   Used by: index.html, shop-all.html, faq.html, 404.html,
   about.html, collections/accessories.html,
   collections/signature-blazers.html,
   collections/summer-blazers.html,
   products/no-notes-use-as-product-template.html
   (and any future page).
   Depends on tokens defined in each page's own :root block:
   --color-cream, --color-red, --color-black, --font-body,
   --font-editorial, --weight-regular, --weight-light,
   --nav-height, --nav-padding-x, --page-padding.
   css/tokens.css must be linked before this file on any page
   that uses it — font-size and letter-spacing throughout this
   file read tokens.css's --text-* and --tracking-* variables
   (--text-nav/--tracking-nav for nav-role text, --text-dropdown/
   --tracking-dropdown for dropdown-role text) and will drop to
   initial/inherited values if tokens.css isn't linked first.
