/* «Dezén» — пневсервис. Метафора: дорога и протектор.
   Лето — выгоревший бетон, резина и жёлтая дорожная разметка. Зима — ночной мокрый асфальт и лёд.
   Шрифты семейства Fira (Mozilla / Carrois): Extra Condensed — вывески и цифры как на дорожных знаках,
   Fira Sans — текст, Fira Mono — размеры, цены, время. Без свечений и градиентов «для красоты». */
