Shadow DOM autofill + Turnstile test

Two identical forms. The blue one lives inside an open shadow root. The green one is ordinary page markup and exists only as a control. Tap the first field in each and see what your browser offers.

1. Make sure this device has a saved address or contact card.
2. Tap First name in the blue panel. Note what is offered and what fills.
3. Do the same in the green panel.
4. Answer the questions at the bottom and copy the result.

If a panel behaves oddly, add ?only=shadow or ?only=light to the URL to load one at a time. To change the Turnstile challenge, add ?key=interactive or ?key=invisible.
