 Description : Aspetto della dashboard EVO2, ripreso dal vecchio configuratore NESA
               (old/config_aiotnet.zip, css/app.css): stessa tavolozza, barra laterale,
               card, tabelle, pulsanti, toast, modali, login e cassetto sotto i 768 px.
               Nessuno stile in linea nelle pagine: la Content-Security-Policy li vieta.
