T38 grid: held-out statistics missed by the best Naibbe-family variant in each section (fresh seeds)

The line layer is the knob that helps most on average (mean |z| 11.4 to 7.6), by design, since its strength is fitted to the layout statistics. The codebook and the within-line shuffle change little on average.

Not supported: no variant reproduces any section; the best settings differ by section and lose one to two statistics on fresh seedstext B 5 (stay95, codebook, shuffle, layer); herbal B 6 (stay90, codebook, layer); pharmaceutical A 7 (per-unit, codebook, layer); stars B 8 (per-unit, codebook, layer); herbal A 9 (stay50, codebook, layer); biological B 10 (stay95, shuffle, layer)0
