   Type:     Display  — Space Grotesk
             Accent   — Cormorant Garamond (small caps / italic)
             Body     — Inter
   Signature: the triangle from the mark — used as a forward-motion
   marker (list bullets, tier indicators, section dividers) because
   recovery at Delta is framed as continuous forward progress.
