This userscript intends to generally prevent websites from detecting specific user actions by blocking their ability to listen for certain browser events. It intercepts and disables the registration and dispatch of events like blur, focus, visibilitychange, copy, cut, contextmenu, selectstart, and others commonly used to track focus changes, disable right-click, or monitor clipboard activity.

Overrides addEventListener, removeEventListener, and dispatchEvent for targeted event types.
Forces document.hidden to false and visibilityState to 'visible'.
Forces document.hasFocus() to always return true.
Clears any existing onblur, onfocus, or visibility handlers.
Applies to iframes and shadow DOMs as they're created.
Automatically re-applies every second to persist through dynamic changes.

Intended for use cases where sites try to monitor user attention or restrict standard browser interactions through JavaScript.
