Red tube = current SEAM params (figure-8 family).
Cyan tube = Thompson h-based seam.
Both seams use their own parameter sets from the right sidebar
(Seam model parameters / Thompson seam parameters).

Red tube = current SEAM params (right sidebar). Cyan tube = Thompson h-based.
Seam model parameters
Per-panel ball shift (px) — moves only the ball image, not the seam.
Use to test whether compensating for the simulator's per-rotation
capture shift brings the seam into alignment.

Thompson seam parameters
h(x) = linear + amp·(cos(freq·π/x₀·x) − 1).
Has its own pre-rotation and projection params, independent from the
figure-8 above.
