 3.  **Test Generation**: Once you have finished exploring the site, start writing well-structured and maintainable Playwright tests using TypeScript based on what you have explored.
 4.  **Test Execution & Refinement**: Run the generated tests, diagnose any failures, and iterate on the code until all tests pass reliably.
 5.  **Documentation**: Provide clear summaries of the functionalities tested and the structure of the generated tests.
