/* ============================================================
   ARTIGO DO BLOG (03/10/2026) — só nas páginas /blog/<slug>, depois do style.css.
   Arquivo próprio para não pesar nas outras páginas e para não disputar o style.css
   com outras frentes de trabalho. Mesmos tokens do site (:root do style.css).

   Leitura e conversão:
   - capa entre a abertura escura e o texto; coluna de leitura de 720 px (18 px, 1,75)
   - no desktop, coluna lateral fixa com o sumário e um card de diagnóstico sempre à vista
   - chamadas no meio e no fim do texto; laranja só nos botões de ação
   - barra fina de progresso de leitura no topo
