This screen showed chips and no explanation; iOS has carried one all along,
under a comment claiming both apps use the same words. They now do.
The last sentence is the boundary: a level decides who can open a file, not
where it can be put. Neither app stops somebody filing sensitive material
somewhere low, and saying so is the honest half of android#15.
Also repairs a comment the emoji sweep truncated, which left the test
saying 'the -property is NOT enforced'.
