Measure action responsiveness independently of display refresh
The practical problem
A high-refresh display is not a substitute for responsive event callbacks when the JavaScript main thread is blocked.
Implementation protocol
Measure pointer timestamps, callback duration and visible presentation in a browser trace. Compare idle performance with animation and third-party scripts enabled.
Worked scenario
A 100-millisecond long task can delay an action even when the screen refreshes every seven milliseconds. Remove the block before increasing decorative animation.
What could go wrong
Do not convert number of animation frames directly into milliseconds.
Acceptance criteria
Report measured distributions for the tested hardware.
