          "2. Capture a short burst: get_preview the target several times spaced ~0.3–0.5s apart (4–6 frames). Confirm the frames actually DIFFER — if they're identical with the timeline running, that itself is the finding (the look isn't animating; trace why with fix_reactivity).",
          "3. Optionally read the driving signals: get_td_nodes on the reactive CHOPs to see if level/beat/motion are actually moving, which tells you whether the stillness is upstream (dead signal) or downstream (signal not mapped to anything visible).",
          "4. Judge on motion axes: liveliness (is anything moving?), variety (does it evolve or loop tightly?), smoothness vs jitter (flickering from raw unsmoothed signal? — suggest bind_to_channel attack/release), and musicality (does the motion relate to the beat or is it arbitrary?).",
          "5. Give concrete fixes: e.g. 'add slow feedback for evolution', 'smooth the bass binding (attack 0.05 / release 0.4) to stop the flicker', 'tie the zoom to the beat'. Report what you observed across the frames, not a generic single-frame critique.",
