Playwright is an automation library that automatically waits (auto-waiting) before each locator action for the element to be in the DOM, visible, enabled, and stable — like an experienced elevator operator: you just press the floor, and the operator checks that the doors are fully closed and the cabin is ready before moving; you never think about timing. But if Selenium can also wait with `WebDriverWait`, why do we need Playwright's automatic waiting? Because in Selenium, if you forget to write a wait at any step the test becomes flaky; Playwright builds this into every action, eliminating human error from the start. On the Java side Playwright offers smart waiting compared to Selenium's `Thread.sleep` and ships with the `microsoft/playwright-java` binding. For a QA engineer this difference is directly reliability: the overwhelming majority of flaky tests stem from missing/wrong waits, and Playwright's auto-wait largely eliminates false FAILs in this category.

Replace the TODO line with the critical line from the expected solution. This is not a real runtime; the goal is to reinforce writing the correct structure in a controlled way.

Why Does Playwright Bring 3 Browsers With Just One Dependency?

In Selenium you had to DOWNLOAD a separate driver binary for each browser (chromedriver, geckodriver); Playwright bundles this into ONE `com.microsoft.playwright:playwright` package.

Adding the dependency to pom.xml does…

Adding the dependency to pom.xml does NOT download the browser binaries — it only adds the Java API to the classpath.

The mvn exec:java ..…

The `mvn exec:java ... CLI ... "install"` command downloads the ACTUAL Chromium/Firefox/WebKit binaries — this is a separate step that needs to run ONLY ONCE on first setup.

Result: instead of `selenium-java` + `webdrivermanager` + 3 separate driver installs, Playwright needs just ONE dependency + ONE install command.
