+ * @param {T | (() => T)} initialValue - The initial value or a function that returns the initial value
+ * @returns {[T, SetValue<T>, () => void]} A tuple containing:
+ *   - The current stored value
+ *   - A function to update the stored value
+ *   - A function to remove the value from storage
+ *
+ * @example
+ * ```tsx
+ * const [theme, setTheme, removeTheme] = useLocalStorage('theme', 'light');
+ * setTheme('dark'); // Updates both state and localStorage
+ * removeTheme(); // Removes from localStorage and resets to initial value
+ * ```

+ * - SSR-safe: Returns initial value during server-side rendering
+ * - Automatically serializes/deserializes JSON
+ * - Handles localStorage quota exceeded errors
+ * - Handles invalid JSON gracefully
