/* ============================================================================
   STS Crew — foglio di stile unico.

   Tipografia: IBM Plex Sans e IBM Plex Mono, self-hosted (nessuna CDN: l'app
   deve funzionare anche con la rete lenta in aula). Plex ha un disegno tecnico
   che sta bene a un centro di formazione per la sicurezza, e regge bene le
   tabelle dense; il mono accompagna telefoni, codici e stati.

   Colore: il brand STS resta l'accento — navy #00528C e azure #0181CA dal
   sigillo, rosso e verde dalle luci di navigazione della cima. Le superfici
   sono quasi bianche con dominante fredda, e la struttura la disegnano i bordi
   sottili, non le ombre: è ciò che distingue un'interfaccia attuale da una
   scolpita in rilievo.

   Un solo tema, chiaro, deliberatamente: qui si leggono tabelle e testi di
   messaggi, e il contrasto non deve dipendere dalle impostazioni del sistema.
