/* ============================================================
   SCROLL CINEMA — intro de entrada + "filme" de planos da home.
   Só é usado em index.html. Tudo aqui é visível sem JS/motion:
   o estado oculto só existe sob html.motion (ver style.css, seção BASE).
   ============================================================ */

/* ---- Intro de entrada (só home, 1ª visita da sessão) ----
   Oculta por padrão. Só aparece com html.intro-pending, que o script inline
   do <head> põe quando não há ie_intro_seen e não há reduced-motion.
   A coreografia é toda CSS (~1,8s): o IE entra, "Ideal Elétrica" se abre a
   partir dele, o véu sai. A saída termina em visibility: hidden, então mesmo
   se intro.js falhar o site fica livre. intro.js só cuida de pular e limpar. */
