   NOTA SOBRE TIPOGRAFIA (Manual de Aplicação da Marca — Janeiro 2025):
   A família tipográfica institucional indicada no manual é "Codec Warm".
   Os arquivos licenciados (.woff2/.ttf) da fonte Codec Warm não estão presentes
   no repositório/assets. A pilha tipográfica abaixo prioriza "Codec Warm" de
   forma centralizada (--font-sans) e utiliza temporariamente "Inter" (já
   integrada ao projeto) como fallback geométrico de alta legibilidade.
   Assim que os arquivos licenciados forem disponibilizados em /assets/fonts/,
   basta descomentar os blocos @font-face abaixo sem alterar componentes.
