   PLAS Academy — Blog (TEMA CLARO)
   Estende os tokens globais (global.css). Serve ao índice
   (/blog/) e ao template de post (/blog/<slug>/).
   Regra do projeto: o conteúdo do blog tem fundo branco / cinza
   bem claro (sobrepõe o "preto dominante" das LPs). Nav e footer
   globais continuam escuros.
