Fun for the whole retro family!

./client contains the client side (browser) portion of application code.

./server contains the server side (backend) portion of application code.

./scripts contains project-wide scripts which are useful to integrate and run the client and server together.

For now, we're standardizing on Node 20 (v20.18.0, the latest LTS version) for both client and server. This may change later, but for now it simplifies environment management to have them be the same.
