Website is loads mobile first, even on desktop

Seems like the site is loading the mobile components first on load, then switching to the desktop ones after a short delay.

Wondering if it's to do with use handling some of the media queries through JS instead of CSS, which means they aren't run until the site is fully loaded? Since we ought to be taking a mobile-first approach, we shouldn't really be changing the order the components are rendered in, I think.

Only option to avoid this might be to handle all the breakpoints/media queries through Stitches instead.
