Agree, it seems like it’s insanely hard to back up a modern JS-enabled web page in a usable way that results in a single file which can be easily shared.

Also check out https://archiveweb.page which is open source, local, and lets you export archived data as WARC (ISO 28500). You can embed archives in web pages using their Web Component https://replayweb.page.
