There is a lot of great detail with your design process that you document in your case studies. Very thorough and alot of good thought put into your design decisions.
One thing I would think about is putting your case study files on your home page. I know you talked about wanting a focused experience so maybe there is another way to execute on your idea (because I do feel that allowing the user to focus on their goals and not having distractions is important), but essentially what you have now is a “load case studies” button.
Research is showing that people prefer to scroll than to take the extra actions such as clicking. Additionally, it’s not about the number of clicks, but it’s about making sure each click makes sense.
