   ═══════════════════════════════════════════════════════════════
   Escrita como camada sobre o CSS acima, de propósito. O conteúdo
   do site e as correções já validadas (mobile, modo manutenção,
   painel da Mia, cascata do menu) continuam intocados — esta camada
   só troca a linguagem visual. Ordem importa: por vir depois, ela
   vence nos conflitos.

   O que muda: tipografia de título vira serifada (Playfair), cabeçalho
   de seção deixa de ser centralizado e ganha numeração, cards ficam
   com borda fina e linha de destaque no hover, e o ritmo de espaço
   fica mais generoso. O que NÃO muda: a paleta ciano da marca.
