/* v3 «Жива 3D-майстерня»: общее для обеих вёрсток — токены дня и ночи, шапка, кнопки,
 * карточки станций, панель крупного плана, постер. Своё у компьютера — desk.css,
 * у телефона — phone.css (отдельная вёрстка, а не адаптация).
 * Тема: data-theme="auto" — как в системе; "day" / "night" — выбор посетителя.
