The timing cues were match-only, and the walk cycles bounced

CLASSIC TENNIS, third time asked and this time actually found. Both cues open
with a mode gate and I checked the wrong two features twice: drawApproachRing
(the closing circles that show when to tap) and drawApexBand (the serve bar
with the gold perfect window) each began `if (!G.match ...)`. So the mode whose
whole pitch is "if the core tennis is good everything else is good" was the one
mode with neither. They run on `G.match || G.mode === 'tennis'` now — the gore
mode stays out on purpose, there is no rally there. A test reads both function
bodies and fails if either is ever gated on the match alone again.

(The two I kept pointing at — the landing ring and the placement ring — really
are shared. They were just not the ones being asked about.)

THE BOUNCING WAS IN THE ART, and measurable: the six generated families came
back with the shuffle frame 30-44 px shorter than the stance it walks out of,
against 9 px on the hand-made racket family. The game draws every frame at its
own PNG height, so the body rose and dropped once per step. A walk cycle is one
drawing with the legs moved and must be one height; _zsheet levels the stance
and the stride pair now and leaves the forehand its own, exactly as the serve
and the fall keep theirs. All seven families re-cut: spreads are 1-8 px.

THE BENCH GETS BUTTONS. Arrow keys are not a control scheme on a phone, which
is the device the walk has to be judged on — so every family and every wound
stage was unreachable from the place the problem shows. Three on-screen pads:
BODY, WOUND, POSE, the two-way ones split left/right. Geometry lives beside the
drawing and input hit-tests the same function, the rule the rack established.

THE FALL is quicker still (0.05/0.07/2.0/0.30): drop, lie there, get up.

Three umpire lines pulled — ump_wound_you, ump_felled, ump_wound_opp2. Not
funny enough to keep. Files deleted, call sites collapsed to the two that stay.

60 tests green.
