   "Don't just report the number. Prove it."
   Financial/audit software: clarity over decoration. No gradients, no
   fake-AI shimmer, no meaningless motion. Palette and type choices
   carried forward from the earlier dashboard-preview pass (navy/teal/
   gold, Fraunces display + Inter UI + a monospace for codes/ids). */
