   CALCULADORA DO PREJUÍZO INVISÍVEL DO FIADO — MultCard
   ---------------------------------------------------------------------
   CONCEITO VISUAL
   O produto vive na fronteira entre dois mundos do supermercado:
   1) o TERMINAL DE PDV — tela escura, monoespaçada, fósforo verde —
      onde o problema é digitado e calculado (perguntas, progresso).
   2) o CUPOM FISCAL — papel claro, "impresso", com itens e total —
      onde o problema se torna palpável (tela de resultado).
   A jornada do usuário atravessa esse contraste de propósito:
   do dado invisível ao prejuízo impresso, em preto no branco.
