/* ==========================================================================
   mad-site.css — o visual do SITE PÚBLICO do produto.

   É a folha inteira do site: não depende de mad-ui.css, Bootstrap ou Tailwind.
   Tipografia do sistema (nenhuma fonte baixada), layout em grade simples e
   contraste conferido nos dois sentidos.

   Marca: `--site-brand` e `--site-brand-fg` são injetadas pelo layout a partir
   do tema do projeto. Todo o resto deriva daqui.

   Voz (STYLE-GUIDE §Voz): sem roxo, sem gradiente em texto, sem brilho/glow,
   sem malha de pontos, sem animação de entrada. Monoespaçada só em código.
   Seção não é cartão: o que separa blocos é espaço e fundo, não borda.
