/* Inkfinity Tattoo. Foglio di stile scritto a mano: build.js non lo tocca.
   Token dal brand book 2026: Matte Black #121212, Champagne Gold #C5B358,
   Petrol Green #00444A, Carrara White #F5F5F5. Playfair Display + Montserrat.
   Regola del brand book rispettata: l'oro non e mai un fondo pieno, salvo
   un gradiente leggero sul bottone principale. Il petrolio vive solo negli avvisi. */
