• The above PR fixes early return for blocks with duotone support but no duotone styles, preventing any further generation of global styles for the current block type.

This is testing nicely for me in the post editor and global styles with #43300 applied. Both font family and text decoration are applied to all text elements within the block, including the author bio if provided in the user settings:

LGTM! ✨
