   Azul da logo + branco. Verde só para sucesso, vermelho só para erro.

   Regra de layout: cada tela cabe inteira na altura visível do celular,
   sem rolagem. O app ocupa 100% da altura e, se o conteúdo não couber,
   js/fit.js aplica níveis de compactação (data-fit="1".."4" no .app):
   espaçamentos e elementos visuais diminuem, e elementos de apoio
   marcados com .fit-2/.fit-3/.fit-4 saem nessa ordem.
