+
+Add `fontStack` option to built-in themes, supporting `"rounded"` and `"system"` variants.
+
+You can now opt out of using [SF Pro Rounded,](https://developer.apple.com/fonts) using default system fonts instead.
+
+**Example usage**
+
+```tsx
+const theme = lightTheme({
+  fontStack: 'system',
+});
+```
