Launcher badges on the message notification (the service notice
explicitly never badges). Stories accept picked videos — validated
against a 30s/9MB cap rather than transcoded, said honestly when
refused — and play looping in the card via the framework player. The
wire's dur field travels for any attachment that has one.
Parental controls mirror iOS: a parent's PIN guards adding contacts,
stories, and calls; incoming calls answer busy; sign-up gains an
on-device age gate that stores nothing. The server learns nothing.
