/*
 * Customer Console — tema chiaro "pannello industriale".
 * Portato da ../plc_console.jsx (prototipo React) a CSS puro: stesse scelte visive
 * (rack LED su fondo scuro, KPI, striscia piattaforme, tabella, slide-over, modale),
 * zero dipendenze: nessun framework, nessun CDN, font self-hostati (vedi fonts.css).
 *
 * NB: l'App cliente usa theme.css (tema scuro white-label). Questo file è SOLO per la
 * Console del proprietario: i due frontend non condividono la palette apposta.
