         *   data-gallery-section="scene"       → ScrollMagic scene anchor
         *   data-gallery-masonry="container"   → append target for new batches
         *   data-gallery-item                  → per-item selector / entrance hook
         *
         * After appending new <figure data-gallery-item> nodes call:
         *   Gallery.refresh()   to register them with the lightbox.
