`stuff.` grew to accumulate a lot of…  um, stuff, over the years

and i never bothered organizing much of it so now i can’t remember what of it is actually sort of “permanent”, e.g. used as a blog header image or linked from somewhere

so i made a `volatile` directory for stuff that’s explicitly temporary—maybe i’m just showing a work in progress to a small group of people, or whatever—and reserve the right to nuke everything in it whenever i feel like it

it’s unbrowseable to enforce that no one can stumble upon it and try to make more permanent use of anything in there
