   Convención de rutas de imágenes:
   - La carpeta  Imagenes_Sitio/  debe colocarse dentro de  public/
     ej: public/Imagenes_Sitio/SIELSIC_notfound.PNG
   - Vite sirve  public/  desde la raíz, por lo que las rutas
     que empiezan con  /Imagenes_Sitio/  funcionan tanto en dev
     como en el build de producción sin modificación adicional.
