MIME type error on demo site

[IllyaMoskvin]

Just wanted to let you know that the demo site is currently non-operational due to an error caused by javascript hotlinking.

simoncozens.github.io/:1 Refused to execute script from 'http://github.com/simoncozens/calzone/raw/master/h-and-j.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.

...which in turn causes:

simoncozens.github.io/:31 Uncaught ReferenceError: Calzone is not defined

I think you can find the fix for this problem here. Good luck, and thanks, I'm looking forward to seeing calzone in action.
