/* Guide (cluster) pages: page-cluster-article.php, rendered by inc/cluster-view.php.
   Same tokens as the blog (assets/blog.css): Inter, one accent, hairlines, soft depth.
   Numbered sections beside a sticky contents list, then the topic series, other topics and
   the call to action. No bands, gradients or pill badges. Plain CSS (no Tailwind rebuild).
   LinkedIn guides (data-pbtheme="linkedin" wrapper) swap the accent. */
