/**
 * CTS2026 Theme — assets/css/product-lightbox.css
 * Lightbox de galería del producto individual.
 *
 * Isolation notes (Elementor-safe):
 *  - Todos los selectores usan el prefijo #cts-lightbox o .cts-lightbox__
 *  - z-index 1000100: por encima del search-modal (999999) y los popups de Elementor (~9999)
 *  - body.single-product scope para evitar filtraciones en páginas del editor
 *  - cursor: zoom-in SOLO en .cts-product-gallery__main (ya es exclusivo de esta plantilla)
 *  - No se usa .elementor, .e-, ni ninguna clase del namespace de Elementor
