Browser extension guide
The extension owns its own sign-in handoff and Device Session. Treat the popup as the source of truth for extension setup.
What to expect
A healthy extension flow signs in from the popup, reconnects its own Device Session, and then creates a `web_selection` Clip that appears in product state.
Expected button flow
Run these checks in order when the extension does not behave as expected.
- 1
Start sign-in from the popup, not from a disconnected browser tab.
- 2
Confirm `App URL` before you retry auth or Capture.
- 3
Use `Load Current Selection` or `Save Selection Capture` only after the Device Session is healthy.
