   Contratação do Projeto ESSENCIAL

   A gramática vem das páginas de venda, não de um sistema paralelo:
   fundo papel, tinta quase preta, Times italic para o que é humano, Arial
   para o que é instrução, régua de 1px no lugar de sombra, e nada arredondado.

   A ideia da página: uma prancha sendo montada. A coluna da esquerda é a
   especificação; a ficha escura da direita acompanha e fecha a conta.
