/* «Для родителей», блок «Как OmniStudy помогает» (templates/public/parents/how.html).
   «Две дорожки»: белая полоса во всю ширину окна; по центру на пунктирной
   оси — четыре опоры, слева кусок приложения ребёнка, справа кусок кабинета
   родителя за тот же день. Каждая опора — своя строка из трёх колонок
   (опора в разметке первая: так её читает диктор и так она стоит на
   телефоне — опора → ребёнок → кабинет). Куски интерфейса — шрифтом
   сайта, вес до 800 (как parts/app_shot.html). */
