/* ============================================================
   КАТЯ РЕПЕТ — главная, 2026/27
   Оформление взято с презентации вводного урока: синий мир
   с сиянием, Unbounded в заголовках, салатовые акценты, белые
   и салатовые карточки, наклонённые наклейки, макеты устройств.
   Один мир без светлой/тёмной темы — все цвета заданы явно.
   Страницы предметов и документы по-прежнему на styles.css.
