Oliver, after the facing fix: still flashing, female worst. Film-strip
diagnosis in the pane: with facing pinned the racket STILL alternated —
frame 4 of the female cycle tucked it across the body, and half the frames
of both player cycles lost or shrank the hoop to cut fragments (overlapping
figures sliced by the even-spaced valley cuts).
Both cycles re-rolled with three new prompt rules that now live in
_runroll.py: the racket stays right of the midline in EVERY figure (named
again for the airborne pose, where it kept vanishing), and the figures
never overlap (no more sliced hoops — a debris-stripping pass was tried
and removed: after the recrop a real racket is indistinguishable from a
fragment, prevention beats cleanup). The model returns 2-row grids at
times; a coherent band is cropped and cut. Installed: racket-side spread
+0.01..+0.05 across all frames of both cycles (was a full side swap).

Oliver: 'the motion seems very flashy and unnatural'. Two causes, both
measured: drawChar centres a frame by its total width while the racket's
reach varies across the cycle, so the BODY teleported sideways up to 28
source px on a frame swap (the female player was worst) — every frame is now
padded until its lower-third centroid sits at the frame centre (residuals
±0.2 px, the normalisation lives in _runroll.py's cut). And the hardcoded
4.5 cycles/s was tuned on 2-4 near-duplicate frames; on eight real phases it
was a strobe — rolled sets stride at TUNE.runHz (2.4), old art keeps 4.5.
In-pane: body wobble down from ~36 device px per swap to 3.2.

The old run frames were generated one at a time and it showed: 91/110/92/98 px
of body-width drift, duplicated poses drawn differently, no racket. Each
character (player m/f 6 frames, opponent m/f 8) now comes from ONE 4K call
anchored on a composed identity reference of its settled frames — the broken
run art stayed out of the reference on purpose. Stride-gated, cut with _fine,
judged by eye per roll. drawChar probes run8/run6/run4/run2.
Side effect: the male opponent's old run art faced LEFT against the
art-faces-RIGHT convention — he had been moonwalking right since install.
Fixed by drawing the new rows to the convention.
Pipeline lessons recorded in PROJECT.md (the model negotiates the count; a
back view has no direction; the racket clause goes early and loud).
