I'm getting ready to add handling for "what if you don't *have* a
current password*??", so it seems like the right way to do that is to
just eject the controller and start customizing!
Motivation is that I wanna add NeoPass stuff to here! But also like,
it's looked bad for a long time, let's clean it up!! (I just used the
Devise default without any styling at all lol)
