Debug builds still reference .handlebars, but files are renamed .js

[publickeating]

It seems that sc-server recognizes .handlebars extensions and returns the matching .js file. In order to load a debug build on a staging server though, the server would have to be configured to do the same. It seems smarter to either not rename the templates as .js and leave index.html alone or change what gets included in the built index.html.
