/* ==========================================================================
   Thème SIO Leçon - réseau / système (BTS SIO)
   Utilisation : appliquer class="sio" sur un <div> ou un conteneur.

   Même principe que cyber.css : les couleurs viennent des jetons --sio-*
   posés par le thème Moodle SIO (theme/sio/scss/post.scss), avec une valeur
   de repli pour relire une page seule dans un navigateur.

   C'est cette charte - bleu nuit et cyan - qui donne sa palette au site
   entier. Le violet de cyber.css en est l'accent d'un domaine.
