/* ============================================================
   NTM Blog — Hero

   Compact dark editorial banner. Teal eyebrow, single-word
   serif headline ("Insights"), italic-teal subhead, and a
   short description. Soft teal radial bloom behind the
   headline, contained and edge-smoothed so it doesn't band.
