Adding custom font to navigation in Rally template

I'm trying to add a custom font to the navigation on my site. Have tried dozens of answers from other similar questions, but nothing is working for me. As you can see, I have successfully added the Windsor font throughout the rest of the site, but hung up on navs: https://soybean-drum-48b6.squarespace.com/

Thanks so much for your help!
