Inspect a mocked network request

This check runs the article’s request.js with a mock fetch function. It sends no POST to collector.example and does not test Chrome extension permissions or CORS.

Choose a case and run the check.

No request captured yet.

The valid input is https://example.com/account?sample=demo#details and Demo account. Compare the input with the JSON body: the origin survives; the path, query, and fragment do not.
