I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.
Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.
I swear that I read that white lead oxide is water soluble, thus happily sticks to your fingers and then gets on your food. I must be misremembering.
Maybe it was something about the solid lead object turning into an (oxide) powder that can then be easily ported as tiny particles on greasy hands? Hearsay science and safety information from me today :)
The fun thing about Pb is it’s relatively safe in pure form. Unfortunately the oxides that appear on its surface are water soluble and love entering our bodies.
Just looked this up, apparently I’m completely wrong. Maybe I was thinking about lipid compatibility? Not sure now.

A lot of phone modems ship with their own SoC (processor) running its own OS. It’s much smaller and slower than the main phone SoC but, depending on its implementation, it can have full access to all of your main processor’s memory through DMA.
Read-only, or the ability to edit filenames & upload files?
Read only: as per other answers here, basically any HTTP server. The easiest one I know would be darkhttpd, because it requires no config files and can be run without root.
