/* ==========================================================================
   Research Detail — aligned with About/Investors editorial system (Swiss)
   Goal: match About page feel:
   - inner max-width 78–88ch
   - headings as kickers (uppercase label) for sections
   - editorial body rhythm (1.12 lede, 1.02 body)
   - replace “pills TOC” + heavy cards with quieter, editorial structures
   Requires: --space-1..--space-6, --border, --text, --muted
   Optional: --bg, --shadow-1
