Detailed Description

Z&H sphere-array drag A/B: collocated EMBED momentum (setFaceInterp(5), Basilisk embed.h true-normal
dirichlet_gradient wall drag) vs mode 0. ROBUST convergence: run past a min-step floor until the drag
drifts < 5e-5 over 200 steps (avoids false early plateaus), report K + the residual drift so convergence
is visible. Incremental-rotational pressure + warm-start. Success: order -> ~2, error below mode 0.

protected

Select a collocated scheme by the integer face-interp mode this script was written with:
0/7/9 are the public strings ('plain' / 'embed' / 'gauge-exact'), 5/6 the diagnostics rungs,
and every other number was deleted at 1.0.0 (the call then raises).
