/* Estrada fora: conceito de página para uma transportadora. Mesmo modelo da Entre marés
   (o scroll conduz um filme de dez segundos), com quatro capítulos, sem som e com tema
   próprio: asfalto, amarelo de sinalização e Barlow, a letra das placas e das matrículas.
   As marcas de via tracejadas ligam os capítulos e as etapas do fecho.
   Telemóvel e ecrãs ao alto: o filme ocupa o ecrã inteiro.
   Ecrãs largos: o filme fica numa coluna vertical, na resolução nativa, com luz ambiente
   tirada do próprio fotograma (ver `.ambient` e app.js). */
