The benchmark built stock from spacing and quadrant only, so engines were
scored on clamp-free sheets and baselines were never checked against the
clamps they were made with. Stock now comes from NestStockBuilder.FromTemplate,
as in desktop Auto Nest: the source plate's rail is resolved for every
candidate size (explicit zones are offered unchanged), and baseline plates
keep their rail and removed clamps.
