/* css/site-chrome.css — unified CodeB site chrome (header + nav + footer)
 *
 * Layered on top of css/style.css. Reuses existing .site-header / .site-nav /
 * .site-nav-link / .site-nav-toggle / .site-footer classes; adds the new
 * structures introduced by the 2026-06-11 redesign: dropdown groups, Sign-in
 * CTA, user chip + dropdown, unified footer.
 *
 * Mobile breakpoint: 820 px (matches existing site CSS).
