Allocation Guard Branch Animation

Create a 10-second teaching animation from [approved allocation-check diagram]. Move one small marker through the input calculation to the documented rejection branch. Keep boxes, expressions and arrows fixed, with exact text in approved overlays. Do not simulate huge memory allocations or show a success badge. End with a two-second hold on the guard condition.

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.
