/* ============================================================
   Aportize — base das calculadoras
   Depende dos tokens e do reset de chrome.css.
   Carregada antes da folha específica de cada calculadora.

   Aqui mora só o que três calculadoras usaram sem variação:
   a grade de duas colunas com o fio, o campo em destaque,
   os fields preenchidos e os rótulos. O que é de uma só
   continua na folha dela.

   Regras herdadas: um único elemento alto por página, nenhuma
   caixa, raio de canto só no que é clicável, monoespaçada só
   em algarismo.
