/* =========================================================
   MPC Sonorização — Design System v2
   Direção: "Evolução do console" — mantém a linguagem de mesa
   de som do site anterior (canais, hz, freq-divider, paleta
   ink/brass) e aprofunda com elementos que realmente respondem
   ao scroll: meter-bridge animado no Hero, rail lateral tipo
   channel strip, freq-dividers vivos. Nada disso compete com
   as fotos/vídeos reais — fica na periferia, como instrumentação,
   não como protagonista.
