/**
 * KataGo neural network input encoder.
 *
 * Produces the binary spatial feature planes consumed by KataGo's ONNX model.
 * Based on KataGo v1.14 input format ("v5" features):
 *
 *   bin_input_global_ncplane  [1, C, N, N]  float32
 *   global_input              [1, 19]        float32
 *
 * Feature plane layout (C = 22):
 *   0   current player stones
 *   1   opponent stones
 *   2   current player stones T-1
 *   3   opponent stones T-1
 *   4   current player stones T-2
 *   5   opponent stones T-2
 *   6   current player stones T-3
 *   7   opponent stones T-3
 *   8   current player stones T-4
 *   9   opponent stones T-4
 *  10   current player stones T-5
 *  11   opponent stones T-5
 *  12   current player stones T-6
 *  13   opponent stones T-6
 *  14   ko point (current player may not play here)
 *  15   board edge / padding (1 outside board)
 *  16   1 if board is 9×9 or smaller
 *  17   1 if board is 13×13 or smaller
 *  18   1 if board is 19×19
 *  19   always-1 layer
 *  20   next-is-second-pass (pass-alive ko)
 *  21   positional superko (0 for simplified version)
 *
 * Global input features (19 values):
 *   0   komi / 15  (normalised)
 *   1-7 (reserved / zero for simplified version)
