   Duas de Vila — Site oficial (landing page pública)
   Depende de tokens.css e manual.css (carregados antes deste arquivo).
   Mobile-first (min-width), ao contrário do manual.css (desktop-first) —
   desvio deliberado: a maior parte do tráfego chega por QR Code, no celular.

   contato → rodapé → responsivo.
