The two destinations were a filled Button over an OutlinedButton, and the
success line said "Exported 1 list" and nothing else.
Now they are an M3 Expressive ButtonGroup — equal-weight tiles that grow and
squeeze their neighbour on press, corners morphing square — and the outcome
carries the SAF Uri it was aimed at, so the receipt is a tinted row naming
the folder or zip, with an Open button when something on the device answers
for it. Failures get the same treatment.
