I love functional prop projects like this and reading through the build log.

How far are you going for the rugged vs prop aesthetic? Have you considered alternative form factor screens? Have you considered something else than an RPi that could work with a GPT/LLM such as an NVidia Jetson (yes, I know, expensive) or a separate compute module? Do you store just things like Wikipedia or a bunch of PDFs such as "Where there is no doctor?" and "Wilderness Survival Guide?" along with other disaster recovery books?

I missed this project the first couple of times it was posted so glad to see if pop up today.
