What can it tell you about a page?

The client can inspect a page snapshot that describes elements such as headings and buttons. Use that view to ask whether the page presents the name and control you expect. For visual details, inspect the actual page separately. A snapshot is one way to check what the browser exposes.

Which browser should the client see?

Use a fresh isolated profile and an owned local demo page with fictional data. Do not attach the browser you use for work or personal accounts. This server can interact with pages, and the project explicitly says it is not a security boundary. Verify the intended browser and page before any test.

Can a fictional visitor find the title and next button?

Sketch an owned local demo page with a heading and a Continue button.
