   /insights — the health blog

   A TOPIC-LED MAGAZINE, and a deliberately different design from the newsroom
   (news.css): a tinted hero with a photo collage, a sticky topic rail, an
   asymmetric editor's-picks block and a soft, image-led card grid. The two
   pages share only feed.css's pager.

   Everything scoped under `.blg`. Logical properties throughout.
