- With an object selected, a brush stroke grows the selected mask it starts on (or the nearest selected one) and
shift trims it, instead of adding a new object on top. The chip shows ✎; ↺ drops the edits (new /bfs/segpick/edit
route). The brush stays on after applying.
- clean_masks (default 0 = off): on every frame, and on the picked frames before tracking, pieces smaller than that %
of their subject's area join what surrounds them: stray specks where subjects touch switch color, holes are filled,
stray background bits go away. Each subject's largest piece always stays.
