/* ===== Shimmer placeholders =====
   Цель: не показывать чёрные квадраты на местах ещё-не-загруженных картинок.
   Решение:
     * fallback background-color (чуть светлее --bg-base)
     * shimmer ::after, GPU-accelerated через transform (не background-position)
     * играет только на элементах без .is-loaded — этот класс ставят:
       - main.js:initShimmerImages   для .bn-visual с <img>
       - hero-fx.js                  для .hero-tile после preload/crossfade
       - main.js:initLazyBackgrounds для .final-cta-tile / .how-visual
     * content:none на .is-loaded полностью удаляет ::after из box-tree,
       анимация останавливается, GPU-layer освобождается.

   Hero t1-t5 (LCP-кандидаты) НЕ shimmer'ятся: у них preload+fetchpriority
   и при прогретом кеше они отрисовываются first paint'ом. Shimmer там
   только ухудшил бы LCP. */
