/* ==========================================================
   AIMAXIMUS — IMAGE LIGHTBOX v1.0 (28-MAY-2026)
   Visor de imágenes elegante, ligero y sin dependencias.
   Se activa solo en imágenes con atributo [data-zoom].
   Coherente con el principio de velocidad: sin rAF perpetuo,
   sin listeners globales de mousemove sobre elementos con blur.
