/* course.css — страницы курсов /kursy/ и /kursy/<id>/ (этап 4 плана функций, 11.10.2026).
   Стиль новой главной «Живая аура» (решение владельца: все новые дизайны — в нём): чернильный фон,
   Unbounded в заголовках, Onest в тексте, стеклянные карточки, живой шар цвета курса (--c).
   Layout: одна колонка ~ 880 px; вверху заход с шаром и кнопкой, дальше дни списком, «Кому / Как»
   двумя карточками, текст, дисклеймер, FAQ, источники мелко. Классы с префиксом crs-. */
