Could you please do it for the default style

Also, run build:registry in apps/www directory

[brianle1301]

@sadeghbarati The default already has these classnames. And sure, I can do a build

[brianle1301]

@sadeghbarati Running build:registry seems to remove all the final new lines of the json outputs. Is this expected?

(Only the color and index ones I might add)

[sadeghbarati]

I'll check. Thanks 🙌
