/* === NOTE ===
 * Le pagine dei moduli Cockpit (Panoramica, Servizi, Log, Storage, ecc.)
 * vivono in iframe e hanno il loro CSS PatternFly che non possiamo coprire
 * con questo file. Per loro restano i colori PatternFly originari -- non
 * stridono col tema perché il chrome esterno (header/sidebar) è ora TRON.
 *
 * I moduli custom (es. "Bans") hanno tema TRON completo perché caricano
 * direttamente bans.css con !important sui propri selettori.
