Section Break Orientation Scope Sequence

Create a 12-second document-layout animation from [approved section example]. Show portrait pages, reveal the bounded middle section and rotate only those pages to landscape. Keep surrounding pages unchanged and display the existing header-link status separately. Do not remove text, renumber pages or shift content without depicting the consequence.

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.
