   «КЕРАМОГРАНИТ 74» — сеть салонов плитки, ИП Шендель В.Ю.
   Дизайн-система по прототипу 10 «Порода и колода»:
   тёмная палитра обожжённой глины, Playfair Display italic + Inter,
   пилюли-кнопки, плитка как главный герой на всех страницах.
   Здесь — общее для всего сайта: типографика, шапка, футер,
   кнопки, формы, модальные окна, подборка. Разделы главной —
   в home.css, страницы каталога — в catalog.css.
