/* ============================================================
   Insights (Blog Library) — page-specific styles only.
   Reusable design-system pieces (reset, container/section/eyebrow/h2/
   btn, nav, footer) live in shared/global.css — this file only adds
   what's unique to the library index: hero, category filter bar,
   article card grid, digest band, solution/industry cards, audit
   banner, contact form.

   Content page rule: this page belongs to no single pillar/vertical,
   so its own accent is brand green (.eyebrow--green below). Individual
   article/solution/industry cards carry the accent of whatever
   pillar or vertical they represent, via the .cat-* modifiers.

   CATEGORY ACCENTS

   FOOTER OVERRIDES
   The shared footer partial's badge row doesn't wrap and its pills
   don't guard against mid-label breaks — fine at the 1280px container
   width it was built for, but the pills squeeze and wrap mid-word
   once the row gets narrower than their combined width. Page-level
   fix rather than editing shared/global.css, since global.css should
   stay generic across pages.
