max
The largest input-grid (lattice) size that sampleInputFeasiblePoints will enumerate exactly rather than rejection-sample. When the number of distinct feasible grid points is no larger than the request and no larger than this cap, the feasible set is enumerated directly (exact, deterministic, no wasted draws); otherwise rejection sampling is used. The cap guards against materializing an enormous grid if a caller requests an absurd number of points; realistic population and design sizes stay far below it.
