            // chaining: resource?.loseContext?.(device)
            //
            // In a full C++ implementation, you would either:
            // 1. Define an interface with loseContext() method
            // 2. Use type traits to detect if the type has loseContext()
            // 3. Let the resource handle device loss through the event system
