Gah! Well, the saga continues. Got myself a new 32GB SD card (a Samsung) and used the Pine64 Installer to install the Ubuntu Container image - so this is Pine64's tool and the images it provides. Same exact story. Actually took two power-on attempts to get it to boot. Once it was booted, I had a simple look around without changing anything. Commanded a reboot and... you guessed it. Board wouldn't come back up. Tried several power cycles and, nothing. No white LED, no display activity.
I should point out that I'm doing all of this with just the basic board, no add-ons. I even took it out of the NAS case some time back. And I have been taking ESD precautions (grounded bracelet etc).
So maybe this board is faulty? That's now three different OS images, three different SD cards plus the now useless eMMC module.
I've used a lot of SBCs - first time I've had this kind of trouble.
EDIT: Ubuntu booted again after several power cycles. Tried with the Debian image too. Booted, but saw messages about failure to load rockchip firmware. Wouldn't reboot.
