Give the rally its length back: deep balls, baseliners, approaches off short balls

Every match had collapsed into serve, both at the net, reflex volleys at
~0.7 s per shot. The rally ball landed on the service line by definition,
the match CPU stood on the bounce and volleyed 90-100% of everything, and
the auto-run chased the earliest contact.

Rally modes only (classic + every match; gore and the duel untouched):
rally balls land deep and mistiming only shortens them (no new long outs);
each shot latches the receiver's plan as it leaves the racket — from the
back he lets it bounce and meets it falling, up to 2.2 m behind the line,
a short ball pulls him in and he follows it to the net, nobody approaches
a man already there, and a volley below the tape is a weak block. Measured:
contacts 10.5-13.7 m from the net, back-court volleys 0-8%, 0.8-1.0 s per
baseline shot. Three new tests pin the shape; v361.
