   Peitoril Vidraçaria (loja fictícia, site de exemplo da prospecção).
   Papel frio, petróleo na ação (a cor da borda do vidro) e amarelo de fita de
   obra como detalhe. Barlow Condensed no display + Barlow no corpo.

   Duas camadas:
   1. Base (sem classe): página estática e completa. É o que vê quem tem
      prefers-reduced-motion ou está sem JS.
   2. html.motion: o roteiro de rolagem. O app.js publica o progresso de cada
      cena em variáveis CSS (--e, --q, --p, --x) e o CSS desenha o resto.
