   ----------------------------------------------------------------------------
   O visualizador só existe depois que a pessoa toca em "Iniciar tour": antes
   disso a seção é uma imagem de 54 KB. O motor 3D (1 MB) e o modelo (0,3 MB)
   entram sob demanda, porque boa parte de quem abre esta página está em campo,
   no Norte, com conexão ruim — e o pior tour do mundo é o que não carrega.

   Carregar depois do /assets/css/kit.css.
