have you adhered to the license? https://github.com/dgtlmoon/changedetection.io/blob/master/C... . if so, where can I get a copy of the source?

Yes — the project is Apache 2.0 licensed (https://github.com/dgtlmoon/changedetection.io/tree/master?t...), which permits forking and commercial use. There's also a COMMERCIAL_LICENCE.md in the repo for hosting/resale cases, and I've reached out to the maintainer directly about it. Attribution is here: https://docs.sitespy.app/docs/acknowledgements

I used to run into this type of problem frequently. I've found that personally adopting something like https://conventionalcomments.org really helps with ambiguity.

I think the big reason to put syntax highlighting in the language server is you have more info, ex you can highlight symbols imported from a different file in one color for integers and a different for functions

You can enrich highlighting using information from the language server, can't you? I think JetBrains does this
