It seems to me to be an appropriate translation. However, I am concerned about the sections where the list items that should be indented are not indented. (Although they appear to be indented in Markdown)

This "Recap" section seems to be in the same position in the EN version.
If it is not about this section, it would be appreciated if you could give more details.

I see, understand! Thanks for your reply 🙏

Similar issues have occurred in past PRs (e.g., #11476 ), so it might be an error specific to the preview environment.
