   PIATTAFORME SU MISURA — il progetto della pagina #catalogo
   --------------------------------------------------------------------------
   Questo foglio si carica DOPO piattaforme-hub.css e ne riusa i token, i
   pulsanti (`.hx-btn`), le sezioni (`.hs`), la galleria, il FAQ, il modulo e
   il visualizzatore. Qui vivono solo i componenti nuovi.

   Il mondo visivo non è stato sostituito: stessa carta, stesso inchiostro,
   stesso viola, stesso IBM Plex, stesse finestre scure da prodotto. Quello
   che cambia è la densità e il ritmo: la pagina precedente era una scheda
   prodotto, questa è un ragionamento, e un ragionamento ha bisogno di
   respiro fra i blocchi, non di una griglia di card identiche.

   Regola ereditata dal progetto e non negoziabile: il fallback statico è la
   condizione di partenza. Nulla è nascosto in CSS; ogni movimento nasce da
   JS e sotto prefers-reduced-motion sparisce mentre la pagina resta leggibile
   e cliccabile.

   1 · IL RENDER CONCETTUALE
   Non è una foto: è un cruscotto disegnato in HTML. Esiste perché questa
   pagina parla di piattaforme che non sono ancora state costruite per il
   lettore, e un rendering di un prodotto inesistente sarebbe una bugia.
   Qui invece si mostra la FORMA: un modello a moduli, un pannello di
   classificazione AI con confidenze, un board di lavoro.
