   Todo va namespaced bajo .pg-gal y .pg-lightbox. No se tocan tipografías,
   colores ni layout del tema fuera de estos contenedores. El único override
   "agresivo" es max-width en las imágenes de la galería (necesario porque
   casi todos los temas fuerzan max-width en img).
   Personalizable vía variables: --pg-cols, --pg-gap, --pg-radius, --pg-neon.
