   Внутри: контейнер .ls-shell, ритм секций .ls-section,
           каркас парящего навбара и подвал. Кнопки, пилюли
           и переключатели живут в ds/controls.css, стекло
           навбара — класс .ls-glass из ds/glass.css.
   Зависит: от ds/tokens.css; навбару нужен ещё ds/glass.css.
   Точки перелома: 960px — меню навбара скрывается.
