Inputs to gather first

interaction performance
event handling

Recommended workflow

1. Profile interactions to find slow handlers
1. Identify blocking operations
1. Determine yielding strategy
1. Implement optimizations
1. Measure INP improvements
1. Test on various devices
1. Monitor for regressions
