/* DS7-Web · /blog/ LISTING (Session K4). Lifted from the designer's
   blog.bundle.html; generalized so the grid renders the live paginated
   collection: per-card images move to inline styles from each post's
   featuredImage (the bundle hard-coded .im-g1…6), and a pagination
   control is added using the page's own .blc__chip treatment. */
