The overlay stores the same path state as the legacy QGraphicsScene item, but MapCanvas can also paint it in the final widget overlay pass after the QSG 1D/2D result frame. That keeps candidate and accepted paths visible above flood maps and result layers that are composited later than the scene buffer. Coordinates follow the standard layer-CRS → scene convention used by SWMMLayerItem (QPointF(mx, -my)).
