Persistent layout shift issue in navbar area with Brine 7.0

Hi everyone! I'm currently dealing with a very annoying layout shift issue in my site's navigation area. I use Brine on Squarespace 7.0. I have a split navigation with the logo at the center. You'll see that when you visit the site both sides of the navigation and the logo are stacked on the left side for a split second, then shift to where they are supposed to be. I've taken some screenshots of it in the incorrect position using Lighthouse, attached below.

I've tried troubleshooting some of my custom code by removing it and refreshing it, trying to see if it's an issue I created. As far as I can tell, it's baked in, but I could certainly be wrong. I could really use a second pair of eyes. Thanks in advance!

Which code did you use to add left nav middle logo right nav?

Hi, thanks for replying! I'm just now seeing this.

I did not use any code to achieve that layout. It is a native option in Squarespace 7.0 Brine's site styles.
