/// <remarks>
/// <see cref="HeykelSavasiContext"/> derives from <see cref="MiniGameContext"/>, whose constructor
/// creates a map and launches a background game loop via <c>Task.Run</c>. Constructing a full context
/// is impractical in a fast unit test, so the balance decision is exposed as a pure static method,
/// <see cref="HeykelSavasiContext.IsJoinAllowed"/>, and tested directly against it.
