Live preview
The phone frame shows your draft (or live) app as you edit.
iOS and Android frames
Toggle iOS / Android to see how chrome and spacing feel on each. The preview loads your app URL with draft mode when you are editing.
Draft vs Live
Draft = current studio work. Live = last published version customers see on the public URL.
Page dropdown
Use the preview Page control to jump between Home and other features. This is separate from the chat Target a page pill (that only guides the AI).
