The toss travels: the receiver watches the serve coming

One event on the toss, replayed as a real toss over O — update() already
poses the server off the phase and drops an uncaught ball back to pretoss
by plain physics, so the wind-up, the cancel and the re-toss all carry for
free. The strike's shot event overwrites whatever drifted.
