-    No `android:packageNames` filter here on purpose: we filter in code by
-    "any package containing 'youtube'" so stock YouTube, Vanced, ReVanced

+    Only `typeWindowStateChanged` is registered.
 
-    Event types intentionally limited to window-state and window-content
-    changes: typeViewScrolled / typeViewSelected fired on every minor UI
-    update inside YouTube and contributed to v1.0.6 firing back-presses
-    on the home screen.
+    YouTube fires `typeWindowContentChanged` at ~30 Hz during normal
+    scroll; even with a 250ms throttle in code, paying for the event
+    dispatch dropped the user-visible frame rate. State-changed events
+    fire only on real screen transitions (opening Shorts, switching
+    tabs, navigating to a video), which is exactly when we need to
+    re-evaluate whether the Shorts player is on screen. Steady-state
+    CPU during scroll drops to effectively zero.
