JavaScript Negative Slice Bounds Sequence

Using [array], [slice start], [slice end], [runtime], move a copy of selected cells to a new row while leaving the original intact. Explain slice bounds relative to array length, clamping and the exclusive end. Distinguish slice from mutating operations; verify the original array remains unchanged. Use 12 seconds unless another duration is specified. Provide camera, reference and continuity notes.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
