    ButtonTourTeleport (LocalScript)

    Place in StarterGui or StarterPlayerScripts.

    Creates a small GUI with a "Start Tour" button. When pressed, it
    teleports the player's character to parts named _Button1, _Button2,
    ..., _Button20 (waiting 1 second between each), then finally
    teleports to a part named ExitRegion.

    Parts are searched for in workspace. Adjust FindPart() below if your
    button parts live in a specific folder/model instead of directly in
    workspace.
