/* ============================================================
   COPEILOT — laboratório de animações da landing (teste, 15/09/2026)
   Ativado por ?lab=1. Bases (html[data-anim]) são excludentes:
     reveal   · o atual: revelação única ao rolar (landing.css)
     none     · sem movimento de rolagem (tudo visível)
     parallax · camadas em velocidades diferentes + mouse na dobra
     scrolly  · animação presa ao progresso da rolagem (reversível)
     pinned   · perguntas empilham como cartões fixos
   Extras (html.fx-*) somam a qualquer base:
     hover · text · marquee · cursor · smooth · skeleton · micro
   Tudo desliga com prefers-reduced-motion (o JS não aplica nada).
