Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 An [artifact](/docs/en/artifacts) that loads a typeface from [Google Fonts](/docs/en/artifacts#improve-the-visual-design) also requests `fonts.googleapis.com` and `fonts.gstatic.com`. Both hosts are optional. If you block them, artifacts render in fallback typefaces. Block with a fast rejection rather than a silent drop so the font request fails immediately instead of delaying the page's first render.
 
+Artifacts can also load JavaScript libraries, such as React or a charting package, from `cdnjs.cloudflare.com`, `cdn.jsdelivr.net`, `cdn.tailwindcss.com`, and `code.jquery.com`, and from no other external host. If you block those hosts, the parts of an artifact that depend on a library don't work, and unlike a blocked font, a blocked library has no fallback. Block with a fast rejection here too, so a blocked library request fails at once rather than hanging until it times out.
