I'm having a very weird (but probably common) issue where any borders I've set for <Card> that I either href link to or back button to will NOT load in, they only show after a COLD RELOAD. It's a small thing, but super duper annoying and I really don't know how to fix it. I've tried just about anything I can think of having to do with layouts, themeprovider, whatever. Nothing works, ever. Attached is what I'm referring to.

Another issue I'm having that's related is that nextjs refuses to load not-found if it is not accompanied by a layout (because it looks strictly for not-found.tsx in /app, regardless of my (main) pathing) and so I have to put a layout in my root - I have a (main) and (landing) - which I don't normally do which just adds to my problems.
