/*
 * Демо ArtUp AR XR (artuplabs.com/ar-xr/demo/): бренд поверх демо-стилей и стили новых частей —
 * цены, выбор для XR, «Мои дизайны», просмотр дизайна в 3D, аккаунт, язык, вход с телефона,
 * демо-админка, итог и «Сохранить план» в XR.
 *
 * Общие токены и компоненты (.ax-*) — в ../assets/ar-xr.css (владелец — лендинг). Здесь для них
 * только запасные правила через :where() (нулевая специфичность): если общий файл не загрузился,
 * окна, листы и кнопки остаются рабочими, а когда он есть — его правила важнее независимо от порядка.
