/// Purpose: Shared XPC contract between the Curtain app (client) and the privileged
///          CurtainHelper daemon (service). Both targets depend on CurtainShared so
///          the protocol and identifiers stay in exactly one place.
/// Inputs: None — this is a declaration unit, not a runtime component.
/// Outputs: The `CurtainDisconnectXPC` remote-object interface and the well-known
///          mach-service / daemon-plist names.
/// Constraints: The protocol is `@objc` because NSXPCInterface requires an
///              Objective-C-visible protocol. The single method is async-by-reply.
/// SPORT: MASTER-DISCONNECT

/// Remote object interface the helper vends and the app calls.

/// Well-known identifiers shared by the app and the helper. The mach service name
/// is what the daemon's `NSXPCListener` registers and what the client connects to;
/// the plist name is what `SMAppService.daemon(plistName:)` looks up under
/// `Contents/Library/LaunchDaemons/` of the app bundle.
