   Proporção das imagens
   Os atributos width/height do HTML servem para o navegador reservar espaço
   (evita CLS). Mas eles também funcionam como dica de apresentação: se o CSS
   define a largura e omite a altura, o navegador usa a altura literal do
   atributo e a imagem estica. Esta regra garante a proporção original.
