 We have a statically-generated Next.js website[^website]. Sometimes, we make typos in our hyperlinks. We would like to have a tool that can detect broken internal links. This should be a tool that runs at build-time and fails the build if it detects a broken link. The tool should be able to handle links to hashes (e.g. `#section`) in addition to links to pages. An initial brainstorm of how this could be implemented is available [here](https://chat.openai.com/share/0e0ffb40-1110-4bd5-8a1a-dd22a0e6483d).
