I've loaded Cesium onto an AWS s3 bucket enabled for web hosting.
Cesium/index.html loads fine and all of the links work out-of-the-box except CesiumViewer and Sandcastle -- neither load beyond a landing page:

Anyone have any thoughts as to what to check where? Is a CORS Configuration needed for the bucket? And what does it need to allow?
