// ❌ LEAK: Closure captures entire large object
function Component({ largeDataset }) {
  const handler = useCallback(() => {
    console.log(largeDataset.summary); // Captures entire dataset
  }, [largeDataset]);
}

// ✅ CORRECT: Only capture what you need
function Component({ largeDataset }) {
  const summary = largeDataset.summary;
  const handler = useCallback(() => {
    console.log(summary); // Only captures summary string
  }, [summary]);
}
