Hi, @YDX-2147483647
Could you please review this?

Good work! I only found minor issues.

In addition to the comments below, there's a Japanese word in CSS .info-box, which is used by some markdown files.

docs/website/src/globals.css

Lines 62 to 63 in 8b03a1c

	.info-box::before {
	content: "情報";

Perhaps it could be changed to emoji? Say, 💡.

(Note that some texts are generated by typst-docs and the SSG can do nothing. If translation is really to be supported, we need to submit a similar PR to the upstream typst/typst.)

Approved! 🚀
