/* ===== TapeDrill — sistema de design do site =====
   USADO POR: index.html, cenarios.html, metodo.html
   NÃO usado por: simulador-vwap.html (esse tem seu próprio CSS inline,
   com a paleta ajustada pra combinar com este arquivo — se mudar uma cor
   aqui, considera atualizar as variáveis --alta/--baixa/--vwap lá também).

   ÍNDICE (Ctrl+F pelo título da seção):
     :root            → tokens de cor/tipografia
     nav              → cabeçalho fixo do site
     hero             → seção de abertura da home
     stat-band        → faixa da estatística de honestidade
     section          → título+texto genérico de seção
     steps / cards     → grades dos "4 passos" e dos cenários
     footer.site      → rodapé
     @media           → breakpoints responsivos (860px e 640px)
