/* =====================================================================
   zeronodipm — Refresh 2026
   Layer di modernizzazione. Caricato PER ULTIMO: ridefinisce i design
   token (sia quelli di app.css sia quelli di znp-product.css) e ripulisce
   gli strati decorativi datati. Nessuna riscrittura dei componenti:
   il sito eredita il nuovo look attraverso le variabili.
   Direzione: moderno, umano, essenziale ma con carattere. Base chiara
   leggermente tintata, accento verde↔blu, ambiance soffusa, gradienti
   d'impatto su hero e CTA. Colore presente ma mai fastidioso.
