* Add profiler body class on initial load, and respect skipped/complete status.
* Handle PR feedback: Remove unnecessary global, add some todos, added a filter around the next step slug, generalized the is-loading class a bit.
* Move non-reset SCSS to a new file
* Split shared files and “meta” files into two folders
This also creates two new base scss files for the different app vs embedded CSS files
* Move notice & embed-specific css out of reset
* Update README with folder structure notes
