/* ============================================================
   Внутренние страницы «Керамогранит 74» в дизайне прототипа 10:
   каталог и фильтры, карточки товара/коллекции/интерьера,
   личный кабинет, вход, правовые тексты, страницы ошибок.
   Подключается на всех страницах, поэтому здесь же живут
   блоки, общие для главной и каталога (интерьеры, галереи).
