/* =========================================================
   STUDIO CAREDDU — DESIGN SYSTEM ENHANCEMENT
   Sovrascrive i default Inter + piatto con:
   - Tipografia serif/sans dual (Playfair Display + DM Sans)
   - Palette estesa con navy di autorità
   - Animazioni scroll-reveal, count-up
   - Texture grain sottile per calore cartaceo
   - Hover più tattili, ombre direzionali
