### Question
How would you manage and switch between multiple tabs or windows opened during a single E2E test execution in Playwright?

### Answer
Given an end-to-end scenario where a user action triggers the opening of a new browser tab (e.g., clicking a link that opens a help document in a new window), describe the idiomatic Playwright approach to ensure the test correctly:

1.  Waits for the new tab/window to fully load.
2.  Obtains a reference to the new `Page` object.
3.  Performs assertions or interactions on the newly opened tab before closing it and returning control to the original page.

Provide a concise code snippet demonstrating how you would implement this logic using a standard Playwright fixture setup.
