A browser testing toolkit for Chromium, Firefox, and WebKit, with locators, retrying assertions, and trace diagnostics.

Reach for it when:
- Testing real user journeys
- Checking deployed builds across browser engines

Worth knowing: Use isolated test data and user-facing locators. Retries can reveal intermittent failures but do not fix them.
