-`binary-preview` derives PNG-only tracking trials from the existing color job
+`binary-preview` makes Random Stroke Pattern (RSP) PNG trials from a color job
 in a separate directory; `--views` selects the multiview job. Stroke width
 follows camera-cell print size, bounded to 0.11–0.28 mm. These image-space
 trials are for probe comparisons, not print masters; UV views may select
