✗ Nested deferred values

The useDeferredValue hook improves UI responsiveness by deferring non-urgent updates. Use it for expensive renders like filtering large lists or rendering complex charts. Always memoize child components and provide visual feedback when showing stale content. It adapts to device capabilities automatically, unlike fixed debounce delays.
