Record a real-device smoke test
The problem
Automated browser tests cannot reproduce every touch, font or thermal issue.
Practical procedure
Use a modest Android phone and a desktop browser to finish one game level and export both tool reports.
Worked scenario
Record browser version, device, date, exact steps and unexpected behavior.
Acceptance check
Treat missing physical-device evidence as untested, not as a pass.
Apply the method
Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
