It would be super useful to have support for variables, similar to what Figma offers. Being able to attach specified values to things like padding, gap, or basically anywhere that allows a numerical input would enable a lot of systematic structure that's currently not natively possible.

It could work similarly to how text style sizing works, where its possible to define a size based on the breakpoint. Variables could allow for a layer of abstraction in defining consistent system-wide values, such as "padding-large" being set to 128px on desktop and 64px on mobile, for example. This would make updating values across all pages much easier.
