/*
 * st-gallery.css — estilos estruturais VERSIONADOS dos blocos de galeria novos:
 *   - GalleryLightbox: grade curada + overlay de lightbox (st-lightbox.js).
 *   - GalleryMasonry: mosaico infinito lazy (st-masonry.js) + mesmo lightbox.
 *
 * Carregado condicionalmente no público (main.php, flags __st_lightbox_enabled /
 * __st_masonry_enabled) e injetado ao vivo no canvas do editor in-page
 * (ensureCanvasRuntimeAssets). Só estrutura/animação genérica — cores e
 * espaçamento por bloco continuam vindo do coletor per-block (/css/page).
 * Sem `!important` e sem `style=` inline. Colunas/gap/proporção por
 * data-attributes (não são estilo inline).
