   cnpj/ob — sistema visual do site público
   Linguagem visual do BoardUI (plano gratuito, MIT): neutros sem matiz,
   um azul de destaque, Inter, cards de 24px, botão primário em degradê.
   Referência: docs/design/boardui-reference.md

   Tema: claro por padrão; o escuro é escolha da pessoa (botão no cabeçalho
   e no rodapé). A escolha vale para todo o *.cnpjob.com.br (cookie
   cnpjob_theme) — site, portal e módulos ficam sempre no mesmo tema.
