   Duas formas, e a escolha entre elas e de contraste, nao de gosto:

   `.tira` e uma faixa cheia entre secoes, sem nenhum texto por cima — por isso
   a foto pode aparecer de verdade. E o que da respiro e ritmo a pagina.

   `.faixa` fica atras de uma secao inteira e so e usada onde o conteudo se
   apoia num painel opaco (o cartao do CTA). Clarear uma foto atras de texto
   corrido derruba o contraste para menos de 3:1, entao ali ela nao entra.
