Looks pretty interesting.. Wonder if this can be done with nothing but browser, CSS, html and a JS without those extra CDNs.

You can verify signatures of JS and CSS files to make sure they are only loaded if they are exactly what you expect them to be by using the "integrity" parameter, see https://developer.mozilla.org/en-US/docs/Web/Security/Subres...
For truly locked-down environments that's the way to go. You can only be sure the code will always be the same if it's 100% local and offline, or verifying signatures somehow.
