Issue: No comparison data.

JSON contains only Usagi 🌙 data. No other creator datasets. Cannot generate other creator info under "no original creation" rule.

Three options:

1. Provide other creator datasets → Write comparison article using that data
2. Write comparison-free article → Switch to standalone feature: "¥5,000 for 69 posts, 4,303 followers"
3. Name known rival creators → Build comparison angles from industry knowledge

Which option?
