Nested text styles: let a style inherit from another

It would be very helpful for design-system builders to create text styles based on other styles, with only the overrides stored.

For example, Body / Bold would inherit everything from Body except the weight. Change Body's font and every child updates.

Today we duplicate and maintain each one by hand, which drifts.

Yes please. Our library has 140 text styles and most differ by one property.

Variables can get you part of the way — bind font family and size to variables, and the styles follow. Not as clean as inheritance though.

bind font family and size to variables

We do that, but weight and letter-spacing per style still multiply.

Thanks for the detailed idea, and to everyone who voted. I've shared it with the team working on styles.
