/* Шапка сайта — подключается отдельно от site.css, использует его токены (:root).
   Одна шапка на всех страницах:
   · bar      — внутренние страницы: тёмная плашка в потоке, прилипает к верху (sticky);
   · overlay  — главная: прозрачная «стеклянная» поверх фото первого экрана (fixed);
   · .is-stuck  — после начала прокрутки обе становятся одинаковой компактной тёмной плашкой;
   · .is-hidden — на телефоне прячется при прокрутке вниз и возвращается при прокрутке вверх. */
