   theme.css — Sistema de tema Claro/Escuro (Mais Contato)
   --------------------------------------------------------------------------
   Estratégia: as cores do site estão "chumbadas" em utilitários Tailwind.
   Em vez de reescrever o HTML, remapeamos cada classe de cor para uma
   variável semântica que muda conforme [data-theme]. O padrão é CLARO.
   Acentos (verde, amarelo) permanecem literais nos dois temas.
