Does anyone have any ideas on how to cover this window?

I plan to use this as a guest bedroom, so it needs privacy. But, it doesn't need to be black out. I was originally thinking I would just install a curtain rod below the transom, but this window is 96" wide and requires a center bracket, which I can't install here. There isn't enough room to squeeze a curtain rod above the entire window. I have no more ideas.

Any suggestions would be much appreciated. Thanks!
