/* ==========================================================================
   QBTech — Informatica ed Automazione Industriale
   Foglio di stile unico, senza build.

   Linguaggio visivo preso dal logo e dal mondo dei quadri macchina:
   pannelli piatti come un HMI, bordi sottili in tono acciaio (la B del logo),
   il blu del marchio pieno e non sfumato. L'unico elemento "forte" è il
   pattern del monogramma QB; tutto il resto resta sobrio.
   ========================================================================== */

/* ---------- Caratteri (locali) ----------
   Saira Semi Condensed per i titoli: le lettere squadrate richiamano "TECH"
   nel logo. Barlow per i testi: nato dalla segnaletica industriale, leggibile
   anche a corpo piccolo. Entrambi semi-stretti, quindi compatti. */
