Mount time is React Native's interaction time, the event duration reported
by PerformanceObserver. It's an INP-like metric covering input dispatch,
React render, Fabric commit, Yoga layout with text measurement, and native
view creation, but not rasterization. Self-measured from the example app as an
average of 3 runs; see
measuring.md
for details.

Memory per view is the difference between memory footprint snapshots taken before and after mounting 5000 views, divided by the number of views. Self-measured from the example app as an average of 3 runs; see measuring.md for details.
