/* Mouratoglou Zephyrhills: center menu with dropdown groups + sub-pages (zephyrhills-*.html).
   Builds on atlanta-pages.css (generic .center-menu-header / .center-subpage / .center-menu-page and .atl-* blocks),
   centers.css and center-international.css (academy theme, --academy-accent #449dd7 on .academy-center-zephyrhills).
   Dropdown behaviour: zephyrhills-menu.js (adds html.zh-menu-js); without JS, hover / focus-within still open the groups.
   Mobile: center-mobile-nav.js turns every .generic-header-links link into the burger menu; sub-items are indented here. */
