Explain one number

Make the same video as the "Explain one number" template on ultramotion.ai: https://ultramotion.ai/templates/explain-a-number/

If you can install skills, run npx skills add sunsiyuan/ultramotion first and use examples/planets-gap/ (narration script.md + picture index.html) in the flat-explainer style as the template: copy it and keep the look, the pacing, the camera, the type and the music exactly as they are; only replace what is in 【】 below with mine. If the words are longer or shorter, change the size and the line breaks, not the structure. The scenes change with your question; the drawing, the camera, the pacing and the music stay the same. If you can't install skills, make the same video as the one on that page from scratch.

My content:
- The question: 【Could every planet fit between the Earth and the Moon?】
- The answer and what to compare it with: 【…】
- The narration (or let the agent write it): 【…】

Deliver: Vertical 1080×1920, 30 fps, an mp4 with music, in the current directory.
