previews [pushT]: force disc moved onto the camera views at the sensor's projected position (was pinned to the GelSight tile) and shrunk to annotate rather than cover; forces recomputed with react_calib — the previous newton values are void (end-to-end rho 0.143 from pixel-unit weights on mm-unit features)
