/* ============================================================================
   Plancia — identità visiva Studio Alma
   Token di colore e tipografia ripresi dal sistema di design di simulazioni
   (teal #00617D, marble #3B3D3E, Montserrat), su layout a barra laterale
   ispirato a Bussola.

   Accessibilità: il responsabile dello studio ha una discromatopsia
   rosso-verde. Regola vincolante — il significato non è mai affidato al solo
   colore: l'asse del denaro è blu-arancio (entrate teal, uscite arancio),
   sempre accompagnato da segno e icona; avvisi ed errori portano icona e testo.
