- Replace custom virtualization with react-window VariableSizeList and normalize import for Vite interop - Implement MeasuredRow using ResizeObserver + requestAnimationFrame; de-duplicate size reports and batch measurements - Wire row height changes to list.resetAfterIndex to keep virtualization accurate - Memoize EventRow, EventBody, and CodeBlock; avoid repeated JSON.stringify to reduce GC/CPU - Replace static SAMPLE_TRACE with a realistic, variable-sized generator (small or very large traces) - Add benchmark script (viewer/scripts/benchEventList.mjs) to measure flattening/positioning performance - Minor TS/type adjustments and small helper cleanup Improves performance and responsiveness for very large traces; reduces layout thrash and render overhead.
