/* ═══════════════════════════════════════════════════════════
   HN Services — Portfólio HORIZONTAL
   ─────────────────────────────────────────────────────────
   O scroll vertical dirige a translação horizontal do track
   (GSAP pin + scrub). 1 painel = 1 projeto: info à esquerda,
   moldura de browser com o vídeo do site à direita.

   Performance: só o painel ativo toca vídeo (JS). Sem
   backdrop-filter / mix-blend-mode no palco. Mobile (<=900px):
   o pin sai, os painéis empilham e cada vídeo toca ao entrar
   na tela (IntersectionObserver).

   Camadas (§4B): palco 1 · progresso/head 6 · lightbox 1200+
