/* ============================================================
   CASA SGUBIN — home stylesheet (v3, harmonized)
   ------------------------------------------------------------
   Brand-aligned (mattone × tortora × carta, Cormorant + DM Sans).
   Fonti di verità:
     - assets/css/tokens.css                          (tokens RGB)
     - design-system/casasgubin/MASTER.md             (Source of Truth)
     - design-system/casasgubin/pages/home.md         (page overrides)

   v3 — armonizzazione post-review LocalWP:
     - Nav da sticky → fixed (elimina la banda beige sopra l'hero)
     - Scala tipografica unica a 4 tier (xl/l/m/s)
     - Section padding unico via --cs-section-y
     - Hero frase: line-height 1.08, max 6rem (era 0.94 e 7.5rem)
     - Tag camere: contrasto 4.5:1 (mattone su carta-deep)
     - Intro + Mattine: spacing compattato
     - Micro-interazioni rifinite
