/* ===================================================================
   STRUCT - LP DE CONVERSAO (Eberick, Cypecad e TQS para o Revit)
   Montserrat + JetBrains Mono | dark, acento azul do Struct

   Folha derivada da LP de lancamento (/lancamento-struct), que nasceu
   para o mesmo assunto. O que mudou: la o CTA levava a um grupo do
   WhatsApp e era verde; aqui ele leva a compra, entao o botao principal
   usa o AZUL da marca e o verde fica reservado ao contato de suporte.
   Fora isso, os blocos de contagem regressiva e de oferta de lancamento
   sairam, e entraram antes/depois, compatibilidade, planos e garantia.

   Principios desta folha:
   - Mobile-first: o layout base e o de celular; media queries so ADICIONAM.
   - Tipografia e espacamentos fluidos com clamp(), sem saltos entre breakpoints.
   - Nada de grid com largura fixa: todo grid usa auto-fit/minmax e reflui sozinho.
   - Performance: content-visibility nas secoes longas, animacoes so em
     transform/opacity (composited), e respeito a prefers-reduced-motion.
