Concrete loads asset libraries that are not needed - how to prevent it?

I installed version 9.1.2 and I noticed that two asset libraries get loaded automatically:

feature/imagery/frontend and feature/navigation/frontend

As far as I can tell there are no blocks that use these assets, at least not on the pages I have looked at. Imagery asset also requires jQuery, which the site does not use, so it doesn’t even work if the user is not logged in.

How do I figure out why these assets are loaded and how do I prevent it from happening?

Bonus question: how do I search for topics on this forum?

Just to clarify, are you looking at the Atomik theme when you’re noticing this, or your own custom theme / a different theme?

Bonus Question Answer: There is a search icon up in the header navigation that you can click that will allow you to search the forums:

It’s a custom theme. These asset libraries do not get loaded with the same theme and the same website content on 8.5.4. I’m happy to dig through the source code and database if you can tell me what to look for.

About the search: Thank you. I can’t see the icon for some reason. The link is there, but I guess Font Awesome doesn’t load for me and there is no fallback text inside the link. That’s an accessibility issue right there.
