As per the title, I've managed to get the initial PCB layout done. It isn't pretty, and I don't like the idea of making it by hand as I had intended, but it should work – barring faults in my schematic (of which there are probably at least a few), routing (possible, but I hope not!) or footprints (hopefully none). Ideally I'll add some copper pours, but I've got to be careful with that because of potentially high voltages in some areas – and on that note, I've got to adjust a few traces to ensure correct clearances around the two current-measurement terminals.

So here's some pertinent details about the design of the PCB:
