   SKELETON DE CARGA — paginas publicas
   ------------------------------------------------------------
   Reemplaza el contenido de muestra (banner y foto demo, textos
   "Cargando...", nombres ficticios) mientras la pagina hidrata
   desde la API. La clase is-public-loading viaja en el HTML para
   que el esqueleto este pintado desde el primer frame; el helper
   assets/js/public-skeleton.js la retira al terminar la carga.
