One of twenty archetypes. Motion comes from data, never from imagery.

Greybox is a codename: the game-dev term for the untextured blockout built before the art exists.

Feed
Each card compresses in place while its thread scrolls; the chart is the visual, not decoration.
Cards
Twenty archetypes, one per data shape, all drawn from structured JSON: The Receipt, The Clock, The Insider.
Rule
No stock footage, no AI video. Precise numbers, no hedging, a rotation penalty so the feed never settles into one rhythm.
Unproven
Design prototype, no backend. Batches are seeded by hand so far; the real test is thirty cards generated unattended from live filings.
