/* ---- Body typography ----------------------------------------------------
   Briefings are dense working documents, not marketing pages.
   Headings are intentionally smaller than the editorial token scale:
     h1  1.9rem     major section break (between --t-h4 1.5rem and --t-h3 2rem)
     h2  --t-h4     sub-section heading  (exact token match at 1.5rem)
     h3  1.2rem     deep sub-heading     (no exact token; slightly above body)
     h4  mono label (matches .label-mono / .eyebrow treatment)
