The match walks back to centre — "unreachable" was the player, not the CPU

"every second ball is basically unreachable by an auto-run player.. are there
some hidden gestures I don't know about or is it just a very strong cpu?"

Neither. The match inherited gore-splatter's depth-only recovery — the
sidestep-protection rule — by being G.mode 'splatter'. One wide return pulled
you off centre and you stayed there, so the next ball to the opposite corner
was lost before it was struck. A player who never walks back experiences
every rally as unreachable, and it reads as CPU strength because the balls
keep landing where he isn't.

The match recovers to centre now, like tennis: real footwork, and in a rally
there is no artillery lane to protect. Gore splatter keeps depth-only — the
sidestep it protects has no role inside a rally. matchSpeedBase 1.4 -> 1.25:
it was calibrated against a player who couldn't move.

The full attacking vocabulary is recorded in PROJECT.md — nothing else is
hidden. The placement flick (aim during the swing) is taught nowhere on
touch; flagged as a ghost-hand lesson if the mode ships.

42 tests, 12 seeds clean.
