There are 4 or 5 different places in the app where we reference a :token and params[:token] for completely different purposes (they're not even vaguely the *same* token).
This is an attempt to clarify the places in the app where we use params[:token] in relation to *orders*, for allowing guest users (who are not logged in) to view details of an order they have placed (like after checkout completion), and differentiate it from the various other places where params[:token] can actually be used for something entirely different!
