The group row's disclosure was an 11px `▸` rotated 90° when open. The property panel's preset runs disclose the same way and draw it at 13px in the mono family, swapping `▸`/`▾` rather than rotating (`hf-fx-preset-run-caret`). Same gesture, so the same glyph at the same size instead of a smaller one unique to this row. Swapped rather than rotated for a second reason: `▸` is not square, so rotating it leaves the glyph off-centre in its 24px box. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
