/* ClosedLoop AI v3 blog-article layer.
   Restyles the blog-post.php shell + the rendered-markdown body typography into the
   v3 editorial grammar (cool ladder, mono labels, hairlines, sharp 2px, no shadows).
   Loaded LAST (body-injected from blog-post.php) so it wins over site.css + blog.css.
   Scoped under .v3-blog (on <main>) so it only touches the article page and never the
   shared nav/footer/other pages. Reading surface stays light + calm: orange is used only
   for progress, the kicker underline sweep, the active index marker, and interaction. */
