/* =====================================================================
   PREVI — landing page

   Ideia condutora: no PREVI, o que já aconteceu é fato e o que vem é
   previsão. A página inteira fala essa língua:
       traço sólido  = fato, já registrado
       traço pontilhado = previsão, ainda por vir
   O fundo de grade vem do mundo do assunto (papel de planilha, calendário
   de parede, extrato). Os valores usam fonte monoespaçada, como extrato
   de banco — dinheiro com cara de instrumento, não de anúncio.
