It's not essential for the PoC, if that's what you mean! 🤣

This .tmux.conf file is part of my debugging setup. Makes it slightly more pleasant to debug inside a docker container. There's quite a few other remnants of my debugging setup that I've not removed from this PoC. For example, it's still littered with my debug printfs. I decided to leave them in this time for that authentic feel. 🤣
