   ECOM PROJECT — Artículos (/blog)

   Hoja propia de la sección, como oferta.css. Solo la cargan blog.html y las
   páginas de blog/. Usa los mismos tokens de site.css: aquí no se define
   ningún color nuevo, todo sale de --accent, --panel, --line, etc.

   Dos bloques:
     1. Índice de la sección  (.posts, .post-card)
     2. Artículo             (.post, .prose, .answer, .toc, .embed, .byline)
