I found the problem! When she pushed the visor back in the hole, it pinched the wires and caused a short, blowing the 'dome' fuse in the under-hood buss. That took out the radio, sunroof, dome lights, door lock switch, steering wheel tilt, and the tail lights, I think. The headlight was a burned-out lamp. I taped off the wires to the vanity mirror in the visor so they wouldn't short again.
I also found a piece of foil in the cigarette lighter receptacle, which sparked quite a bit while I fished it out, but didn't blow the fuse. It probably would have been a problem if I had shoved my phone charger in without looking!
