```[paste code]```

Comments should explain WHY, not WHAT (the code shows what).

Output:

// Debounce user input to prevent excessive API calls
const debouncedSearch = useMemo(
  // Create a new debounced function only when delay changes
  () => debounce((query: string) => {
    // Skip empty queries to avoid unnecessary requests
    if (!query.trim()) return;
    // Trigger the actual search with the debounced value
    onSearch(query);
  }, delay),
  [delay, onSearch] // Recreate when these dependencies change
);
