The promotional loop. 1280×720, drawn live — screen-record it, or export frames below.
Nothing here is a mockup. The key is the real mint sprite, served from /api/key-sprite.
The cities are the twelve the landing-page slider grows through, from /api/demo-sequence —
the same art a wallet of that size actually produces. 20 seconds, seamless.
Add ?v=1 for the vertical 9:16 cut, or ?t=12.4 to hold one exact frame.
