/* ============================================================
   Site navigation  (EWW-13)

   Moved, in original order, out of index.html's inline <style> so
   the homepage and the service landing pages share one header.
   Small teal text and the white-on-teal CTAs use --teal-text /
   the darker gradient for WCAG AA (as in contact-form.css). Order matters: e.g. .mobile-nav a must stay after
   .mobile-language-switch a, and .reference-dropdown a after
   .nav-links a (same specificity, later rule wins).

   Markup: core/templates/core/_site_nav.html
   Script: core/static/core/js/site-nav.js
   The nav is position: fixed (92px, 78px under 760px), so pages
   must leave that much space at the top.
