- Move scroll position and bounding client rect calculations from `pointermove` handler to `requestAnimationFrame` loop. - Use `pointerPosRef` to store raw event coordinates, reducing overhead in high-frequency event handlers. - Ensure spotlight effect correctly accounts for scroll position updates during animation frames. - Add regression test to verify `scrollX` is not accessed during pointer events.
