 * nav-footer.css — Self-contained nav + beautified footer styles
 *
 * This stylesheet is the SINGLE SOURCE OF TRUTH for the site nav
 * and footer appearance. It does NOT depend on shared.min.css —
 * pages that load only nav-footer.css still get a fully styled
 * nav and footer.
 *
 * Edit this file to globally update nav/footer appearance.
