It is the Steam Deck without the screen. Just the controller I ever wanted

You right, I didn’t included screenshots of the generated PDFs yet. Here what it look atm for a draft, then a bill.

As you can see, it is still quite minimal. I intend to add (1) editable user styles, and (2) brand logos you could add to your user account, and to your customers.

I expect the Dockerfile to be quite simple. Would you share your recipe so I can add it the the project root?
