Canvas Board

Planning boards on an infinite canvas: frames, sticky notes, shapes and connectors with snapping, a JSON clipboard and undo, saved per board in IndexedDB, with owner and viewer personas and seeded scenarios.

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.

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