The device was purchased in Dec 2018, and just now put into service; it is
a year (at least) out of date.
I was holding the boot-select button, and it did act as expected, selecting
between booting from the eMMC (not pushed) and the SD card (pushed) at
power-up/start.
It seems that the forced directive in uEnv.txt was ignored, though, so I
presume that uboot did not read the uEnv.txt from the SD card even if
booting from it.
