This is interesting. Is the intended use case mostly read-only websites like blogs/docs/essays? How well does it handle sites where navigation, search, dropdowns, or other UI interactions depend on JavaScript?
Currently, all of that is broken. At one point, I had a traumatic experience where an archived HTML file kept redirecting to the live site, even though I already had all the content rendered, so I ended up disabling all JavaScript entirely.
If there's more demand for that, maybe I will implement a more relaxed version.
