I've tried researching this like crazy, and all I've come up with is PHP solutions.. which sadly, our Magento 2 site is managed by Magento Certified third-party, and I don't have access to play around with the themes or PHP files myself..
(and yes, I know that is technically the 'better way' of doing things.. but obviously some values are already accessible without doing so, and that's what I'm looking for.. just whatever is already accessible without making file changes.)
I know that I can use something like this to pull the Customer's First Name (also 'fullname' works, but I don't know what else does.):
<div data-bind="scope: 'customer'" style="display: none;"> <span data-bind="text: customer().firstname"> </div>
Is there a list somewhere of other attribute-names I can use to get other values? Also, what are some of the other scopes, and some of their values? (Company, etc.?)
Thanks in advance!
