Using Adobe Typekit for Fonts on ONTRApages?

My snooty designer insists he should hard code all the pages so we can use these Adobe Typekit fonts he has in his Creative Cloud subscription to, and I quote, "create a dynamic, consistent look and feel for better branding and longer life" (or something like that).

I really like ONTRApages, and I kinda like this designer guy when we're talking about football. Do I need to fire him or can we use Adobe TypeKit fonts in ONTRApages.
