You're getting close to making your own CHM format, which Sphinx could make for you.

I always thought CHM files were a nice self-contained option for multi-page HTML docs. (Though they'd happily execute whatever JavaScript the author embedded in there... Maybe that's why they fell out favor?)

It would be great if there was an open CHM-like format that was supported by all major browsers. The nice thing about browsers is that everyone already got one installed. They can even open PDFs natively these days. Sadly, they cannot even open epubs (which is almost like CHM without interactivity). I believe firefox used to be able to open epubs, not sure what happened.

The "Portable EPUBS" discussion happening nearby is on this subject, too.

Edge could. MS cut it out long before the move to the chrome rendering engine.
