/* ══════════════════════════════════════════════════════════════════════
   INSIGHTS (/blog/)
   Styles for the article index and the long-form article template.
   Layers on top of styles.css and css/landing.css — reuses their tokens,
   nav, footer, buttons, breadcrumb (.lp-crumbs) and .fade-in reveal, so
   Insights reads as part of the same site rather than a bolted-on blog.

   Generated pages come from tools_generate_blog_pages.py — edit POSTS
   there and re-run, do not hand-edit /blog/**/index.html.
