   banner.css — Pop-up avvisi (public.banners)
   Stila il markup generato a runtime dal binder
   (static/site-injection/pages-binding.js → initBanners):
     .banner-popup            overlay full-screen, centra la card
     .banner-popup__card      card centrale
     .banner-popup__close     pulsante × in alto a destra
     .banner-popup__img       immagine opzionale
     .banner-popup__title     titolo
     .banner-popup__body      testo
     .banner-popup__cta       call-to-action (il binder gli mette anche
                              la classe `btn`, qui inesistente → stile pill diretto)

   L'host `<div data-banners hidden>` (in layouts/base.html.j2) parte nascosto;
   il binder fa `el.hidden = false` solo quando trova un banner attivo da mostrare.
