The screenshot you'd post anyway — with numbers recomputed server-side.

Trading communities run on screenshots, and screenshots are trivially faked. A card whose numbers are server-verified and whose scenario anyone can replay is a different kind of artifact — it invites checking rather than belief.
You share results that stand up to scrutiny, and every share brings the next trader to a simulator instead of a sales page.
All outputs are descriptive probabilities of scenarios you define — educational tool, not investment advice.
