   Trust Study — Publication Edition
   ────────────────────────────────────────────────────────
   Design principles (TypeUI Publication):
   · Editorial whitespace — sections breathe, nothing cramped
   · Sharp geometry — no rounded cards, hairline rules
   · Display-grade type hierarchy — headings command, body recedes
   · Color as punctuation — accent on labels and numbers only
   · Pull-quote callouts — centered, large, italic
   · White space > card backgrounds for separation
