/* ============================================================
   La home B2B.

   Porting degli stili della consegna di design lidia-web del
   20/09/2026 (src/app/globals.css, sezioni hero, trust-strip,
   feat, proc, diff, switch, hitl, facts, net).

   Prefisso b- per non incrociare le classi fp- della home
   precedente, che resta nella storia di git. I colori sono i token
   del tema: la consegna usa gli stessi valori con nomi propri.

   Il grigio secondario del tema non fa da testo sotto i 14 punti:
   sul fondo chiaro sta a 3,09:1. Al suo posto il nero a opacita'
   ridotta, con il rapporto annotato dove serve.

/* Il velo, in due strati, e il perche' sono due.
   Il primo tentativo era un velo solo, uniforme al 60 per cento: il testo si
   leggeva ma la nebbia spariva, perche' una nebbia che si vede ha per forza
   chiazze chiare e coprirle tutte vuol dire coprire anche lei. Il conflitto
   non si risolve alzando o abbassando un numero: si risolve mettendo lo scuro
   dove stanno le parole e lasciando libero il resto.
   Sotto: una velatura leggera su tutto, che toglie solo i picchi.
   Sopra: una fascia scura sul lato del testo, che sfuma prima di meta'
   larghezza. A destra la nebbia resta al 18 per cento di velo, cioe' piena. */
