 * Tema condiviso "pannello industriale": sfondo scuro, monospace, indicatori a LED
 * (verde=ok, ambra=warning, rosso=error, grigio=idle), bordi da rack di controllo.
 * Nessun font/risorsa esterna: solo stack di sistema, funziona offline sulla VPS.
 * Il logo/colore accento del tenant si sovrascrive a runtime via variabili CSS
 * (vedi applyBranding() in app.js) — non toccare questo file per un tema per-cliente.
