   Design system: a digital ledger. Dark "ink" ground throughout; the ledger identity lives in
   the seal mark, Fraunces type, and the red/brass accent pair rather than a literal paper card —
   every screenshot sits in a dark glass "device window" (browser chrome, a colour glow, a live
   autoplay progress line) so it reads as real running software, not a printed page. See tokens
