Rationale

These four gestures trigger system-level functions that iOS users rely on for navigation and device control. Intercepting them breaks system navigation, traps users inside the app, and violates App Store Review Guidelines — apps that do so are routinely rejected. Apple HIG source: Rule 6.2 — Never Override System Gestures.
