Playwright Testing

This handles Playwright test setup with a solid foundation: Page Object Model architecture, role-based locators that prioritize accessibility, and global authentication that saves login state across tests. You get cross-browser configs for desktop and mobile viewports, CI/CD defaults with retries and reporters, and a project structure that separates pages, fixtures, and test data. The locator strategy is smart, favoring getByRole and getByLabel over brittle CSS selectors. Worth using when you're starting E2E testing or refactoring a messy test suite, though you'll still need to adapt the page objects to your actual application.
