Mobile version of store not showing up on mobile- showing as desktop version

I ended up accidentally deleting some code at the top of the the theme.liquid of the Impulse theme. I can’t find what was there before, and I believe that’s why the mobile version isn’t working, when on mobile it looks like the desktop version still. It was a few lines of stuff after line 3 of the code. I believe .meta stuff was deleted? Can anyone help me figure out what code is missing here?

Thank you so much!
