Adobe TypeKit web font embed code

[winterwool]

I've chosen the perfect fonts for my brand identity. They're in use in all my marketing with the exception of my Square Online store.

The fonts are available through Adobe TypeKit's Web Project embed code feature. (Code placed in the header of the HTML)

While I can find instructions on Weebly's discussion boards regarding this topic, I cannot find the options in Square's editing interface.

How can I go about adding the embed code to the head tag of my site? Is it possible?

Thanks for your help!

Update: I found the area where code can be added to the HEAD tag in each page.

(It's in "Integrations" not SEO, as Weebly suggests)

However, apparently <link.... tags are not allowed. Is there a way to overcome this?
