-`stroke-texture` exports Random Stroke Pattern (RSP) PNG/SVG/PDF and a hash
-manifest from existing color artwork, for example:
-`orisys-design stroke-texture sensors/finger/r01 --views`. Outputs go to a
-`strokes` subdirectory; `--output-dir` selects another. Tuning lives in the
-revision's `stroke_pattern` block. Nominal stroke width is 0.11–0.28 mm;
-verify vectors and printed dimensions before manufacturing.
+`stroke-texture` exports black capsule strokes using the same camera grid,
+projection and UV output size as `texture_patch`. First generate the single-view
+texture job, then run `orisys-design stroke-texture sensors/finger-xynova/r01`.
+The stroke output is independent of the color artwork pixels. The revision's
+`stroke_pattern` block controls the seed, width and length ratios, and orientation
+mode; `--output-dir` selects a fresh destination. The command writes PNG/SVG/PDF,
+resolved settings and a hash manifest. Two-view `--views` jobs are not supported.
+The projected-cell ratios do not guarantee a 0.2 mm physical stroke width;
+measure the production SVG before manufacturing.
