LGTM except

two reviews

• docs/website/src/components/ui/common/SearchWindow.tsx

  Line 42 in 4b0856d

  // biome-ignore lint/security/noDangerouslySetInnerHtml: pagefindで生成されたスクリプトを実行する

• The README https://github.com/typst-jp/docs/blob/main/website/README.md is still not in English, is that normal?

you can check with

# using https://github.com/BurntSushi/ripgrep
cd website

The README is currently being worked on at #275.

Only some minor issues that can be changed or ignored.

• page and outline might be confused with functions of the same names in typst. Better to restore the original description.
• Some tenses and writing styles are inconsistent throughout, but I think they're fine for dev doc comments. No need for modification.
