2012 John Deere 5055E - Won't start. No dash lights or instruments. Battery good. PROBLEM SOLVED!

This is a real-world electrical diagnosis, not a review or walkaround: a 2012 5055E suddenly had no dash lights, no sounds, and wouldn't crank, despite a good battery. The owner walks through ruling out the battery and starter, testing the ignition switch and fuse box, and finally finds a burned-into positive wire behind the fuse panel. Most useful for 5055E owners troubleshooting a no-power-to-ignition-switch fault.
