Each prototype stores its data in IndexedDB for the address it runs on. Data you create at localhost:5173 is separate from a build at localhost:4173 or a published URL, and the framed preview shares storage with that address opened directly.

Scenarios 1

Each scenario rebuilds a deterministic world from its seed. Switch scenarios from DevTools inside the prototype, or open a link with ?scenario=<id>.
