"downloading the entirety of Wikipedia" feels right to me given the current political climate
it's easy to download copies of Wikipedia and similar sites for Kiwix, and older copies of them are available on the Internet Archive
there are also programs you can use to download a single webpage (SingleFile) and mirror static websites (wget and HTTrack)
