How do I add a logo to my storefront instead of text?

This is a simple "client portal" within my company's website. We have products listed within that the client can order and we will fulfill, but we would prefer if the storefront had the client's logo instead of the default text header, which right night reads [CLIENT NAME PORTAL].

I just can't figure out if Squarespace Store default header is editable or not. 

Finally, if I can't add the client's logo and have to use the standard text as a header option, can I at least change the font color to match the client's preferred color? 

TIA
