t (channels): merged FIRST then s00..s15; z (frames): 'average' (all scenes) +
'average-f:l' (middle-half, renderSceneSequence default range) then scenes -
same dimensions as -CUAS-INDIVIDUAL-CUAS-DBG (17 x 499 x H x W) so ImageJ can
subtract the stacks directly. NaN-tolerant per-pixel averages. Applies to all
three products (RT-RENDER, -LOG-ORACLE, -LOG-FOLDED). Per Andrey 07/06/2026.
