rerendering input grid (live-data churn)

a grid of login inputs whose surrounding wrapper is torn down and rebuilt every X ms; simulates an input table backed by a streaming data source and exercises lifecycle handling

⚠︎ Caution: exercising extreme values (very large row counts and/or very short intervals) can potentially crash the browser tab.

Use the controls to simulate streaming data concerns driving lifecycle side-effects. Metrics are reported via PerformanceObserver API.
