"""Record a checkout, keep the evidence, then replay it later without an LLM.

1. Record the fixture's checkout form being filled and submitted (every step gets a screenshot).
2. Save the run report (one self-contained HTML file that opens offline) and JUnit XML for CI.
3. Turn the recording into a replay script (ranked locators per element), save it as JSON.
4. Replay the script: no model, no snapshot reading; each step is found again by its locators.
