InDesign engine breaks on gehenna mount

[Inventsable]

Related to battleaxedotco/brutalism#31, I've noticed that external JSON loading via IDSN causes the entire script to fail. I've managed to get around this by going into panel and explicitly setting await gehenna() to !/IDSN/.test(spy.appName) so InDesign doesn't load it, then adding the contents of json2.js to the top of my main script file for IDSN. Need a good workaround and fix for this, since this has been a recurring issue ever since the original cluecumber package release and async evalScript call.
