   ANDIAMO — Design System Foundations
   Colors + Typography tokens (base) and semantic styles.
   Brand idea: the Italian flag (green·white·red) and the US flag
   (red·white·blue) SHARE red + white. The unified palette is therefore
   GREEN + RED + NAVY on warm CREAM, with a Tuscan GOLD accent.
   Load this file first on any page, then use the variables + classes.
