Select a random background image each time the site is built

i didnt think anyone was going to take my joke seriously, a sliding image background/carousel would probably be better. that said not opposed to this

This doesn't make that much sense, since the site is statically built only once when changed.

Yes, and by looking at the commit log I see that it happens fairly frequently (monthly at least). Throw in a bunch of different images and you get some variability without having to update the image manually every once in a while.

I agree a carousel would be better (even though there is already a gallery further down the page). This is a low-tech way to get some of that value with a fraction of the work

While I think randomizing the image on load via JavaScript is preferable, this is a fine solution too.

a serious review to a joke

be fine merging this, but literally no point if your only going to have one image, otherwise its just overhead/debt

I think it's a good preparation to proceed with screenshot debates in another PR. Adding code to support multiple backgrounds in the first place is a good idea. Also the change is straightforward and only needs a few lines.
