/* =====================================================================
   assets/css/base.css – the parts shared by ALL pages (navigation pages AND gallery pages):
   colors, header, breadcrumb, project intro box, footer.
   Same visual style as infoticedu.ro (the "hub" repository).

   On the gallery pages this file is loaded AFTER assets/css/gallery.css, so it must NOT
   change the gallery cards, the lightbox (zoom) or the download buttons:
     - no rules for .card, .gallery, .lightbox, .btn
     - the variable names do not overlap with assets/css/gallery.css (that is why the shadow is --hub-shadow)
