Node Sass hasn't had a release since May 2023. Issues are going unanswered, and this repo is causing at least some amount of user confusion (see #3421, which is a question about Dart Sass). Installation appears to be broken for users with recent Python versions. LibSass put out a release eight months ago that still hasn't made it into a Node Sass release.

This all suggests to me that we can no longer credibly describe Node Sass as being "maintained indefinitely" even on a best-effort basis, and that we should officially mark it as end-of-life, archive the repository, and update the npm package to say "END OF LIFE" in big red letters.
