The racket kept changing hands because the art disagreed with itself: p_idle,
p_bounce and p_toss held it in his LEFT hand while p_smash and p_swing used his
right, so every new frame copied whichever reference it was handed. The idle, the
bounce pair, the toss and the four wind-up frames are all regenerated with the
side named — drawn from behind, his right hand is the right-hand side of the
image, and only the racket HEAD crosses behind his back.
What separates the four wind-up stages is how far the racket has fallen, and that
needed the racket head pinned to a body landmark per frame — above his head,
beside his ear, between his shoulder blades, at the back of his thighs. Described
as "further into it each time" it drew four near-identical poses twice running.
They are wired late in the pull, Oliver's call: frame 1 owns the first half and
the three coiled frames are packed into the top half.
assets/_derive.py is deleted. Fixing generated art by mangling it afterwards is
always worse than regenerating; three guards in _regen.py turn the bad rolls that
used to install silently into automatic re-rolls — a portrait reference canvas
(the generator answered with a 2x2 grid), a non-magenta background (a green sheet
keyed away four racket heads), and a mirrored frame.
The bounce pair is one drawing from one sheet now, differing only in the free
hand, so BOUNCE_IDLE moved to his left side and was re-measured off the sprite.

Oliver, off the file browser: "the racket changes the hand in 3 and 4". It did —
the generator drew frames 1-2 right-handed and 3-4 left-handed. Both mirrored into
line with the rest of the serve (a back-view figure mirrors for free), and the
batch prompt now names the side, since the generator will not hold a prop in one
hand across a sheet unless told to.
The convention the rest of the art already uses: racket on the LEFT-HAND SIDE OF
THE IMAGE, free arm on the RIGHT — the side the game drops the bounced ball and
tosses the served one. p_smash keeps the racket on the right: that is the frame
where it has come over the top to meet the ball it is hitting.

Four new frames (p_pull1..4) turn the slingshot drag into the serve's wind-up:
racket above the head, behind the head, behind the back, fully coiled, picked off
pullFrac — the same 0..1 that sets the shot's power — so the gesture and the man
are one movement and the release snaps to the smash.
The two bounce frames are one drawing now. p_bounce2 is p_bounce with the free
arm sheared up 12px and nothing else touched, so the swap cannot flicker, and it
follows the ball instead of its rising phase; BOUNCE_IDLE was re-measured off the
sprite so the ball tops out under the palm. p_toss had the tossed ball drawn into
it — cut, canvas height kept, because the game scales him off img.height.
The runner: hip centres sat -2.0/+7.1/-6.0/-0.1 px off the sprite centre, a 13px
lateral jump at 12 frames a second, and Oliver's diagnosis was right that all four
frames leaned the same way and lifted the same leg. Frames 3 and 4 mirrored, all
four padded to one width with the hip on the centre line.
assets/_derive.py holds the three derivations, since "the same drawing with one
small difference" is the one thing the generator cannot draw.
