The selector now returns candidate locations with an activity flag, so the quiet half of the finger's sampling grid can be drawn at last: one radius-1 dot per candidate, in the idle tint and off the flow ramp, on no sample that also carries an arrow. The dots are `DRAW_IDLE_GRID_DOTS` (on) and `draw_arrow_display(idle_dots=...)`; box and mini keep their own SDK path.
