Okay, I see. You only need to import each of those css files if you are modifying them. I have since removed everything and gone back to simply:
@import url(../prana/style.css);
Everything is working fine. Maybe my upload didn’t go through before and that’s why the site was still broken after uncommenting the import line. It wasn’t seeing style.css. So, thank you, your original response was all that was needed!
