/* =========================================================
   NAV + FOOTER (new design) — supporting stylesheet
   Loaded alongside the site's existing style.css on pages that
   were updated to use the new header.nav / .site-footer markup
   (matching articles/autm2026/index.html). Scoped to header.nav
   and .site-footer wherever a class name (like .container, .btn,
   .eyebrow) is also used elsewhere on the page, so this file only
   changes the nav and footer, not the rest of each page.
