/*******************************************************
    Landing Reta Final CFC — v5
    Versão mobile-first: hero interativa, demonstração em carrossel,
    oferta principal compacta e ativos responsivos.
    M1: HERO · M2: TRÊS PASSOS · M3: OFERTA · M4: SEGURANÇA RACIONAL.

    Identidade herdada do design system v1.1:
    petróleo + esmeralda + dourado · Fraunces / DM Sans / DM Mono.

    Regra de cor mantida: DOURADO É EXCLUSIVO DA AÇÃO DE COMPRA.
    Como na v5 o CTA principal da hero é de NAVEGAÇÃO, ele usa
    o botão claro (paper); o dourado fica só no link de checkout.
