Overview

Plugin.Maui.ScreenGuard is a screenshot and recents guard for MAUI. Android sets FLAG_SECURE so recents are blank and screenshots are blocked. iOS cannot block screenshots; the plugin shows a capture overlay and raises CaptureStateChanged / IsCaptured when the screen is being recorded. Protect / Unprotect is reference-counted. SetProtected(page, true) ties a hold to a page. It is not AppLock and not FileVault.
