Spreadsheet Error Masking Sequence

Use [spreadsheet formula], [sample inputs] and [intended error policy]. Create a 12-second formula-flow animation sending two documented error cases through a broad mask and then the proposed distinct routes. Keep underlying inputs fixed and label the second route proposed until tested.

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.
