Lightning Design Tokens are so helpful when specifying dynamic CSS variables, which helps to greatly reduce the design maintainability cost of Lightning applications.
Is there a similar concept but for Visualforce pages (Salesforce Classic)? I understand that one can use Lightning Out, create a Lightning component and display that in a Visualforce page hence, could use Lightning Design Tokens that way but I'd rather have an equivalent functionality but for Salesforce Classic.
Is there an equivalent of Lightning Design Tokens but for Classic or is the nearest thing possible to use a custom setting?
