   Overdrive: Instrumento em Aquecimento
   Hero: o glow radial vira uma pulsação lenta de "energia ligada", via

   começa dessaturado com uma linha de varredura, resolve pra cor plena.
   Onde o navegador suporta animation-timeline:view(), a revelação é
   literalmente amarrada à posição de scroll; senão, cai no mesmo gatilho
   de IntersectionObserver que já move todo [data-fade] do site.
