   IAtualidades — main.css
   Folha única do site. Duas camadas:

   PARTE A — Design System (padrão "PRO"): tokens, temas claro/
             escuro, header, seções, cards, rodapé.
   PARTE B — Camada de artigo: sumário, prompts, callouts,
             comparativos, FAQ e demais componentes editoriais,
             reescritos sobre os tokens da Parte A.

   Regra de ouro: nenhuma cor literal dentro de componente.
   Tudo sai de token. Trocou o token, trocou o site inteiro.

     ESCALA FLUIDA
     ------------------------------------------------------------
     O site não "tem uma versão mobile": ele acompanha a tela de
     forma contínua. Cada valor abaixo cresce junto com a largura
     da janela entre um piso e um teto, com clamp().

     Por que isso importa: com valores fixos, o layout fica igual
     de 520px a 1023px e depois SALTA. O leitor de um tablet ou de
     um celular grande recebe uma tela pensada para outro aparelho.
     Com clamp(), cada tamanho de tela recebe a medida certa.

     Os breakpoints continuam existindo — mas só para mudanças de
     ESTRUTURA (grade que empilha, menu que vira hambúrguer), não
     para ajuste de tamanho.
