Original issue

• Fluid typography: add min and max viewport width configurable options #53081
• introduced minViewportWidth and maxViewportWidth as standalone variables for fluid typography.

Additional user need

• It should be possible that minViewportWidth and maxViewportWidth can take variable values like contentSize and wideSize or the defined breakpoint variables to have a synchronized design experience with no need to manually update numerical values in multiple places.

Add ref data type to fluid typography (goal of this issue)

@ramonjd pointed out this is possible by integrating the ref data type as defined in the theme.json schema for fluid typography, then you could assign like this:

	"settings": {
		"appearanceTools": true,
		"layout": {
			"contentSize": "840px",
			"wideSize": "1100px"
		},
		"typography": {
			"fluid": {
				"maxViewportWidth": {
					"ref": "settings.layout.contentSize"
				},
				"minViewportWidth": "600px"
			}
		}
	},
