Rounder Corner and Box Shadow in the author box and comment box

I am an Astra Pro customer. Raised a couple of tickets on this without any response. Looks like Astra does not care about customers who bought the lifetime Astra license.

I don’t have any knowledge of CSS so requesting this simple fix.

I want to have rounded corners and box-shadow in the author box and in the comment box to match it with other elements in the blog. Please see the reference link.

Thanks
