/* ============================================================
   NTM Article — Hero (dark)

   Two stacked clusters on one dark band:
     1. Headline column — eyebrow with flanking teal hairlines,
        large serif headline, subtitle, slim date · read meta.
     2. Actions row — bracketed by hairline rules top and bottom,
        author on the left, four round action icons on the right.

   The radial teal bloom sits behind the headline; it does not
   reach into the actions row.
