/* ============================================================
   SOCIAL: A NOSSA PÁGINA DE INSTAGRAM (V6, 28 set 2026)
   Cena presa ao scroll em três fitas verticais, cores vivas da marca:
   a da esquerda desce de cima, a do meio sobe de baixo, a da direita desce de cima.
   Cada fita é uma parte da cena: perfil, reels, publicação com vários slides.
   Preparada para crescer: cada fita é um .sx-rb genérico (uma rede nova, como o TikTok,
   é mais uma fita ou troca o conteúdo de uma). Só transform e opacity nas animações.
   JS em assets/js/social.js. Prefixo .sx.
