Declares the launch: the first screen, the launch edge's source and ordinal
skip, and — for a platform whose launch sends more than its first screen —
the burst with its marks and the first screen's input from the launch input.
The declaration sends nothing; OpenApp runs the burst, and the first
screen's own enter runs at the burst's firstScreen.
Without a burst the launch is the first screen alone and the caller's input is the screen's input.
