[unknown] After a little more investigation, while it looks incredibly interesting as a pattern to follow (it's all html+css+javascript, so it can be run locally on anything that has a browser), the project has been abandoned for 4 years.
I do think it's worthy of exploration as an exemplar, no real dependencies outside what the web already requires, easy to share, can be hosted as a static site that people can grab and it works completely offline after that.
That said, I don't think it would be a copy paste sort of thing. It uses a bunch of stuff that's probably not needed. If we follow the pattern but keep everything as close to vanilla html+css+javascript, we could make something that should work on any device or operating system.
