"All button-related custom CSS—including variant and size declarations—has been moved from the global stylesheet to theme styles. This ensures tighter integration with native Bricks controls and allows you to leverage Advanced Theme's variable management functions.

Here's an improved version of your text: "New button categories have been added to the Variable Manager, creating a more organized structure that simplifies editing.

The button recipe has been completely revamped to include the newly created variables for each variant type.

Since we are now targeting the Bricks classes directly, we've eliminated the need for button utility classes, which have been removed from the framework.

Each variable category in the ATF section of the Variable Manager now includes a short description indicating where its variables are mapped.

All button variants have been updated with refreshed default styles.

Within any scale in the CSS Variable Manager of AT, you can now choose a base variable from which all other variables in the scale are derived.

Both the left and right panels can now be scrolled independently, making it easier to navigate overflowing content.

The preview updates instantly whenever you modify a color variable in the Variable Manager.

This is a JavaScript optimization related to the left element shortcuts. While the performance improvement is minor, the code is now cleaner and more maintainable.
