   PaleoLab — padrão Steep (serif analytics on warm paper)
   Fonte de verdade: DESIGN.md / tokens.md (skill paleolab-design-system)
   Fontes em produção: Source Serif 4 (serif 400) + Inter (sans 400..500)

   Nesta rodada (v0.16.0) o cliente pediu explicitamente 3 desvios do
   sistema Steep original (documentados também no PaleoLab_Projeto_WordPress.md):
   1) faixa de identidade em peach no lugar do logo/imagem;
   2) menu abaixo do banner na home;
   3) fundo azul nas páginas internas (novo token --canvas-internal).

/* ============================================================
   Correção: o WordPress adiciona a classe "single" ao <body> nas páginas
   individuais (ex.: Trabalhos de Campo). Isso fazia o <body> herdar o card
   branco de "article.single" (fundo branco + padding), deixando a página
   fora do padrão. Aqui devolvemos o <body> ao padrão das internas (azul +
   textura), sem afetar o card do conteúdo (article.single continua igual).
