How to set up Next.js while keeping static header/footer?

A little confused setting this up in next.js while keeping a static header/footer. Here’s a sandbox of my setup: https://codesandbox.io/s/patient-glitter-htiu9u?file=/components/Layout.tsx

Hello @efficient_pelican! This inEditor seems right.:thinking_face:
