/* ===================================================================
   UrielSec — sistema visivo
   ===================================================================
   I due colori dominanti NON sono scelti a occhio: sono campionati dai
   materiali forniti. Il verde #00ff9c corrisponde al verde delle icone
   dei moduli (misurato: #12fd98); il blu #4174c4 e' il blu del logo
   UrielSec (misurato sul pixel piu' saturo del marchio). Cambiarli
   scollegherebbe l'interfaccia dalla grafica dei corsi.

   Ogni animazione usa solo transform/opacity/filter e viene disattivata
   sotto `prefers-reduced-motion: reduce`, in fondo al file.
