+/**
+ * Custom hook to track scroll depth for GTM analytics
+ *
+ * Monitors user scroll behavior and triggers GTM events when the user reaches
+ * specific depth milestones (25%, 50%, 75%, 90%, 100%). Each milestone is
+ * tracked only once per page visit to avoid duplicate events.
+ *
+ * Features:
+ * - Debounced scroll event handling (100ms) for performance
+ * - Tracks depth milestones: 25%, 50%, 75%, 90%, 100%
+ * - Prevents duplicate tracking of the same milestone
+ * - Automatically resets tracking state on route changes
+ * - Checks initial scroll position on mount
+ *
+ * @example
+ * ```tsx
+ * function MyPage() {
+ *   useScrollTracking();
+ *   return <div>...</div>;
+ * }
+ * ```
+ *
+ * @remarks
+ * This hook should be used at the page/route level component to ensure
+ * accurate tracking across navigation. The tracking state is automatically
+ * reset when the URL pathname changes.
