- a secondary/middle press or one on the navigator panned the photo but
also selected or drew a guide: the gestures take the primary button and
skip the navigator's rect
- egui forgets the press origin by the release, so the endpoint drag
compared against the guide's old position: a press that landed within
the grab radius and never moved wrote a no-op guide; the gesture now
carries the press point itself
- a selection left behind by a Delete past the last guide clears with the
photo/tool check in crop_overlay
