/* Cena subsolo (ROTEIRO.md §3–9): descida, problema, serviços, poço do vagonete, método,
   manto, núcleo e rodapé. O achado do convite saiu da descida em 14/10/2026 (virou a aba "Convite virtual"). Começa na cor do chão da superfície (--solo-1, sem emenda) e escurece
   camada a camada até o núcleo amarelo e a rocha-mãe.
   Camadas dentro de .subsolo: fundo e ondas das camadas (auto) → ruído (::before, 1) → raízes e
   lanterna (1) → conteúdo (2) → fita de obra (3).
   Sem JS e com movimento reduzido: tudo visível e parado, raízes desenhadas, pilha do método vira lista.
   Os estilos antigos de .footer, .steps e .service-list (styles.css) seguem valendo em /convites:
   aqui eles só são sobrescritos com escopo .subsolo / .rodape. */
