I have no idea how the PCB got this effect.

    Looks like the coating above the traces didn’t quite stand up to the heat over the years.

    But it looks nice, maybe we can make PCB art with that.

      That might be it. I was thinking it could the a spike in voltage that shorted the traces. But nothing else got damaged in the house, so it is less likely.
