Google's account widget and cookie rotation frames (accounts.google.com /
ogs.google.com) on a signed-in Play Console no longer count as a sign-in
page. Each detection logs its rule and URL; heartbeats name the page; a
copied Chrome session that lands on a sign-in URL is said plainly; the
sign-in wait gets a watchdog dump, and --debug-dump up to 3 dumps.
Fixtures and tests for the chooser and home with the widget frames and a
top-level accounts.google.com page; pitfall 16.
