I've been doing this in pieces bit by bit, not to rock the boat too much
too fast, but it's taking too long, and too much effort. Instead opting
for a rip-the-bandaid style, hopefully without the pain.
Move the files that are copied into the Docker image, into an `fs`
folder, that reflects the folder structure of that in the image. This
means two things right away:
1. A single `COPY` instruction in `Dockerfile` is enough to copy all the
files to their places.
2. The structure of files in the repo reflects that in the Docker image.
This makes working with the files/folders and troubleshooting with them
much easier.
❗ Note: **There's actually only 3 files changed, rest are just moved.**
