/* v3: preenchido pelo agente responsável (v3-motion.css).
   Sistema de movimento: revelação ao rolar, elevação de cards/works/devices/offerings,
   faixa .v3-marquee, trilho .v3-rail e aurora discreta no hero.
   Tudo que anima respeita prefers-reduced-motion e funciona sem JavaScript:
   classes que dependem de JS (.v3-reveal, .is-in, duplicação da faixa) só existem
   quando o próprio JS as adiciona; sem JS, o conteúdo permanece visível por padrão. */
