My store's layout has changed (it has "shrunk") and my store's default set font is no longer working

Hi all,

I logged into my store (customer facing) this afternoon and discovered components of the layout of my store have "shunk" in size, and things like my default set font (Archivo Narrow) is no longer in use on the site. 

I haven't made any changes to any code of theme so I don't know if there is a bug with the theme (I'm using Boost) or something else.

What do I do? How do I check? What do I look for?!?

Help!

My site is thatretropiece.com - when you jump on the site it's glaringly obvious what the issues are.

Thank you - but I have already resolved the issue!
