After a day-ish of trying to figure out a nice clean ( Javascript-less ) way to make a queue to import images, I decided to just forget the queue and let Tanzawa import images as fast as possible. The number of simultaneous requests seems to be limited by the browser anyways.

The last thing I need to do is import individual post content. Maybe it's because I'm not building fun features, but this last Wordpress import feels like such a slog.
