Scenario Controls
Choose one scenario. Both modes use the same burn profile so you can compare how much responsiveness is preserved when the work moves off the main thread.
Interactive Probe
The automatic metrics are repeatable without manual input. Typing during a run adds an extra input-lag proxy using performance.now() - event.timeStamp.
Benchmark Guidance
- Keep the same round count and burn duration when comparing browsers or devices.
- Run main-thread first, then worker, and export separate JSON drafts for each scenario.
- Promote the raw draft only after recording browser, OS, and device context in
RESULTS.md.
