Supported platforms:

CRITICAL: Tests must verify that product features WORK correctly, not just that UI elements render.

Run Playwright end-to-end tests for the Studio application.

End-to-end (E2E) testing validates complete user workflows from the UI through all backend systems, ensuring the entire application stack works together correctly from a user's perspective. E2E tests simulate real user interactions with browsers, handling authentication, navigation, form submissions, and validating results.
