/* ТИМС — стили демонстрации сайта.

   Порядок: токены → база → раскладка → общие элементы → шапка → главная → внутренние страницы
   → каталог и проекты → формы и окна → анимации → адаптив.

   Все размеры шрифтов, отступы секций и промежутки сеток берутся из токенов в :root.
   Минимальный размер текста — 12 px (подписи заглавными), обычный мелкий текст — 13–15 px.
   Блоки разделов, скрытых в сайте-визитке (каталог, отрасли, технологии, новости, квиз, поиск),
   оставлены и приведены к той же системе: они нужны, если включить полную версию в core.js. */
