/*
 * Tema login Figaro Secure Gateway — sovrascrive keycloak.v2 (PatternFly v5).
 * Palette e raggi allineati a public/admin.css (tema scuro navy + accento indigo).
 * Caricato dopo css/styles.css: vince sulla cascata per ordine + selettori mirati.
 *
 * Estetica "console firewall": sfondo a griglia di rete + glow indigo, fascia
 * accento animata, watermark a scudo, tagline e chip di sicurezza, micro-
 * interazioni su input/bottoni. Solo CSS — nessun override dei template
 * FreeMarker, così resta compatibile con gli upgrade di Keycloak.
