+//
+//  Runs XCTest's built-in accessibility auditor over every primary screen.
+//  The auditor catches the classes of defect that are invisible in a normal
+//  UI test but block real users: unlabeled controls, images whose label
+//  repeats the trait, text that clips at large Dynamic Type sizes, contrast
+//  below the WCAG threshold, and hit regions under 44pt.
+//
+//  Each screen is audited independently so a failure names the screen it came
+//  from. The ad SDK is disabled: Google's banner is a third-party view whose
+//  accessibility this project cannot fix, and its network fetch makes the
+//  audit nondeterministic.
