   WELL RUN · SIGNAL SYSTEM — INSIGHTS ARTICLE
   Page styles for /en/insights/<slug>/  (namespace: .ip-)
   Built on Signal Core tokens in global.css.

   A light, daylight editorial long-read — matches the Insights journal index.
   Author E-E-A-T byline is central (Person schema made visible). Layout: light
   hero + byline → key-takeaways answer block → sticky-TOC reading column
   (prose / HowTo steps / callouts / pull) → FAQ → author card → related →
   CTA. One reusable template; every guide is the same structure.
