   Os quatro teasers têm queimada no MP4 só a banda preta (150 px numa moldura
   de 1440×900, ou seja 16,667 % da altura) e o fundo dos cartões. As palavras
   vivem no HTML, uma cópia por língua, e o `site.js` acende-as e apaga-as
   contra o `currentTime`.

   As medidas saem do ffmpeg que gerou o vídeo — fonte 42 px, margem 70 px,
   título de cartão 92/76/68/64 px, tudo sobre 1440 de largura. Daí os `cqw`:
   assim a legenda encolhe na mesma proporção que a banda desenhada por baixo
