I just spent some time updating all the software, fixing some
networking issues, and disabling services on the raspi in question. It
had a full X server + desktop environment booting by default, even
with no display attached! So I disabled all that and now the memory
usage is much lower. I suspect the "OOM killer" was causing these
problems, which fits our experience of features/services dropping one
by one until nothing worked at all - first captive DNS would go away,
then web server would go away, then dhcpd would go away...

It works now. Maybe this time it will work a few hours later. :)
