Pictures turned out ok! I should have done a dry run for my totality setup, as I wanted to do some bracketed exposures and assumed my DSLR would let me do that the same way in live display mode as it does in optical viewfinder mode, and it... didn't. But the pictures I did get are a reasonable, if insufficient facsimile of the experience.
As for the real deal... I'll have to update everyone once I've processed it. It was clear as crystal, and a perfect day. I was totally unprepared in every way that mattered. I don't yet have words.
