/* ═══ Insights: the journal ═══════════════════════════════════════════
   Linked after sub.css on insights.html. The newest article is the hero's
   right column; the rest run as thumbnail rows behind a filter bar built
   from the feed's own tags; LinkedIn posts run as a two-column feed with
   avatars instead of boxed cards. Everything below the hero is painted by
   insights.js from data/feed.json. Written by tools/blueprint_design.py.
