tester.auditAccessibility works unchanged on a live binding, so the rendered
app can be audited on a device or desktop — catching native-semantics and
platform-channel differences a widget test cannot, with real input focus
present. A runnable example lands at example/integration_test, and the
attest_flutter README gains an on-device section with the honest caveats:
contrast needs a debug build, and the text-scale overflow pass relies on a
test-only re-pump, so start with textScales [1.0] on a live binding.

attest_flutter 1.2.2 (docs + example only); core and CLI are unchanged.
