The stage
Live preview & runtime
SoonA frame on the canvas is a snapshot; to see the real app, play it.
- Run a frame. Hit play and the real app route runs in a runtime window — the actual running app, not an export.
- Live updates. HMR keeps it current with your canvas and code edits as you make them.
- Camera / snapshot. Reach a state worth keeping — an empty cart, an error view — and hit the camera. It lands back on the canvas as a new editable frame.
The Run browser
The runtime is also the standalone Run browser: the play-button equivalent that runs the real app while you build, with its own page-tree navigator and select-to-edit.
