   KV-C — Come Funziona "Alternato editoriale"
   Pagina intera (sostituisce il contenuto di <main>):
   1) Hero split: copy sx + ritratto uomo-braccia in cornice
      pastello dx (linguaggio cvB).
   2) Tre step alternati sx/dx: testo vs visual prodotto dentro
      pannellini pastello (#fff7ed bordo #fde68a). Numerazione
      01/02/03 sobria eyebrow-style.
   3) CTA finale: banda pastello con donna-smile ancorata in
      basso a destra.
   Zero movimento: solo hover colore/ombra 150ms. Nessuna
   keyline separatrice. Header flottante ~130px: pt dedicato.
