     O portal não informa a própria altura para a página (não usa postMessage),

     o portal centraliza o formulário na vertical e o fundo dele é o mesmo
     --fundo-formulario do painel; faltar altura, mesmo por 1px, cria barra de
     rolagem dentro do formulário. Então a altura é medida e ainda leva folga.

     Quanto mais estreito, mais alto o formulário fica, até estabilizar. Com o
     formulário atual (Nome, E-mail, Telefone e o botão): 519px acima de 620 de
     largura, 547px a 460, 575px a 400, 603px a 320 e 659px abaixo de 290 (o
     mais estreito que o celular produz; abaixo disso não cresce mais).

     Este valor base atende a coluna única, onde o iframe pode ficar bem
     estreito. A folga aqui é larga de propósito: cabe uma mensagem de erro de
     validação em cada um dos três campos sem a barra voltar, e como a coluna é
     única não há com o que comparar a sobra. */
