   CENA GEOLÓGICA — v4
   Descer a página = atravessar as camadas da Terra.

   Três decisões de performance:
   1. Nada cruza em opacidade. Uma única coluna de 320vh carrega
      toda a geologia pintada; ela apenas translada. Textura,
      veios e câmara são filhos e viajam de graça.
   2. Onde o navegador suporta, a animação roda em
      `animation-timeline: scroll()` — fora da thread principal,
      travada no scroll, sem um frame de atraso. O JS nem entra.
   3. Só `transform`. Nenhuma propriedade que pinte ou dispare layout.
