/* =========================================================================
   Trocellen CRM - sistema di design
   Mobile first: il layout parte dal telefono e si espande.
   I colori sono token: il tema chiaro e scuro cambia solo le variabili.

   Criteri della tavolozza:
   - le superfici salgono per gradini piccoli (sfondo, scheda, rilievo), cosi la
     gerarchia si legge senza bordi marcati;
   - gli accenti sono desaturati: su uno schermo scuro un blu pieno vibra e stanca,
     e fa sembrare urgente ogni elemento colorato;
   - il colore porta significato solo dove serve (stato, soglia, errore). Tutto il
     resto vive di neutri e di spazio.
