meshing.adaptive.surface_cells(
    sdf,
    grid,
    *,
    level=0.0,
    lipschitz=1.0,
    stats=None,
)

Find every unit cell that may contain the level set, by octree descent.

Returns lattice cell indices shaped (cell_count, 3), a conservative superset of the cells the surface actually crosses.
