/* =========================================================
   Blog — listagem "Aprenda comigo" e artigos (rodada 2 · v22)
   Carregado depois de styles.css. Identidade: grafite + off-white + vermelho
   profundo como ACENTO (categorias, filetes, estados ativos, marcadores).
   Só tokens curtos de contexto (--a, --on, --on-body, --on-soft, --on-mute,
   --hair, --hair-strong, --ctl): eles trocam sozinhos entre grafite
   (.s-navy) e off-white (.s-paper). Nunca hex, nunca --gold.
   Chips de categoria: o visual vem do styles.css (.cat-chip, ativo = vermelho
   preenchido); aqui só o layout da faixa de abas.
