Global actors with detached and regular task

Hello. I have a variable marked with one of my Global Actor. Next, I going to mutate it within one of created by me concurrent task. What is different between detached and regular tasks?

// Actors Pool

@globalActor
public struct DuckActor {
  public actor Actor {}
  public static let shared = Actor()
}

@DuckActor var globalTextSize: Int = 0

func checkDuck() {
    Task.detached { @DuckActor in
        globalTextSize = 10
    }
    Task { @DuckActor in
        globalTextSize = 10
    }
    // what is different bertween these tasks?
}

One difference is that the detached task doesn’t include any of the task context. There is more than just the actor. There is also priority and task-local variables.
