I tried it. I disconnected the battery, let it sit for 10 minutes, then reconnected it. No joy. I also checked the wires that were accessible to me; they seemed properly seated, and again, it did not start. It clicked, but that was all.

It has gone off the the dealership on a tow truck, not because their mechanics are better (they aren't) but because that's where I can get work done under warranty, which applies to everything that could cause this. That's another saga, which I'll recount when I know more about what might be wrong with my dragon. For now, suffice to say that my face met my palm repeatedly in the process.
