  * NoOverview Module
- * 
- * Automatically hides the GNOME Overview on startup.
- * This provides a cleaner desktop experience for users who prefer not to use the overview.
- * Note: This module only hides the overview on startup. Users can still access it via hotkeys or gestures.
+ *
+ * Prevents the GNOME Overview from showing at startup by temporarily disabling
+ * `sessionMode.hasOverview`, which causes the startup animation to skip the
+ * overview transition entirely. Once startup completes, `hasOverview` is restored
+ * so the overview remains accessible via hotkeys, gestures, and the Activities button.
