forked from OpenNeo/impress

Moreover, this code is in a bit of a flimsy state anyway: it'll kinda work if you're logged in at impress-2020.openneo.net, but that wasn't intentionally engineered, and I'm not sure exactly what circumstances cause those cookies to send vs not send? My intent is to clean up to replace all this with login code that references the main app instead… this'll require swapping out some endpoints to refer to what the main app has, but I'm hoping that's not so tricky to do, since the main app does offer basically all of this functionality already anyway. (That's not to say it's simple, but I think it's a migration in the right direction!)
