   МосЭкоСила System v3 — system-v3.css
   Композиционные паттерны ds-*. Подключается после components.css,
   перед ui.css.

   Паттерн собирает секцию или крупный блок из компонентов. Новый шаблон
   сначала собирается из этих паттернов; новый класс верхнего уровня
   добавляется, только если существующие композиции не решают задачу.
