//       console.log('Searching for:', debouncedSearchTerm);
//       // Perform API call or heavy computation
//     }
//   }, [debouncedSearchTerm]);

//   return (
//     <input
//       type="text"
//       placeholder="Search..."
//       value={searchTerm}
//       onChange={(e) => setSearchTerm(e.target.value)}
