tvOS full screen covers are transparent, so each one filled itself with a hardcoded black — invisible black-on-black text under the light color scheme (e.g. the View All Comments page). A shared tvFullScreenCoverBackground() modifier now picks black or light gray from the color scheme; applied to the comments cover, subscription destination picker, instance login, edit source, iCloud progress, and legacy accounts import covers.
