Gutenberg-ready?

Is this theme still getting some care from its makers? I mean, it’s being more than 2 years it has no updates and the articles doesn’t seem to be gutenberg-ready. You can see that when you post an audio player in one. The audio player used to be at width 100% in the article, and it’s not the case with a post made with gutenberg (I even tried to edit the html in the post directly but no dice)

I’m a noob at theme editing (tho, i forked duena for my likings and made some modifications on it) but I’m willing to start and maintain a fork to revive it if the makers don’t care updating it…
