Spreadsheet Freeze Boundary Check Film

Create a 10-second spreadsheet animation from [verified boundary example]. Scroll the data region while the specified headers and key columns remain stationary. Keep cell identities aligned at the boundary and do not duplicate rows. End with [expected visible anchor cells].

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.
