   Quiet centred narrow column for suitability notes, contraindication

   "this is a citation". Visually similar to .cta-block but with eyebrow +
   heading + body in place of mark + display text + actions.

   Works on both warm-white and ink (Soft Black) sections. On ink, the existing
   .section--ink cascade flips text colour to warm-white and keeps the brass
   eyebrow dash visible; the brass rule below the heading stays brass on dark.
   Use inside a .section--ink section for trust/positioning moments
   (e.g. Suitability statements) where the visual seriousness matches the
   content. */
