/* ======================================================
   Steklo Shop — Premium Ice Glass UI (v5)

   Что изменилось в этой версии:
   1. Кэш больше не управляется вручную из CSS/JS — версии файлов
      контролируются HTTP-заголовками в .htaccess. Дизайн всегда
      актуален у всех посетителей.
   2. Диамант "24/7": шрифт Space Grotesk (гарнитура для чисел/техно
      акцентов) вместо декоративного Cormorant Garamond, настоящая
      форма ромба (rotate 45deg + контр-поворот текста).
   3. Фото в прайсе — фиксированный кадр (aspect-ratio + object-fit:
      cover), карточка прайса больше никогда не "прыгает", кнопка
      "Назад" всегда на своём месте.
   4. Анимированный фон облегчён на слабых устройствах через классы
      .lite-fx / .no-motion, которые JS вешает на <html> ДО отрисовки.
