   Las url() de un CSS se resuelven desde la carpeta del CSS, no
   desde la del HTML. Este archivo vive en /assets/css/, así que
   para llegar a /images/ hay que subir dos niveles:

       url('../../images/modalidades/training.webp')   <-- correcto
       url('images/modalidades/training.webp')         <-- roto

   En el HTML, en cambio, la ruta es images/... a secas.
