Subject: [PATCH] feat(apple/widgets): Xcode canvas previews for the Live
 Activity + Hosts widget
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every surface renders in the canvas without running the app or starting a
real Activity: Lock Screen banner across all four session stages
(streaming/backgrounded/reconnecting/ended), Dynamic Island
expanded/compact/minimal, and the Hosts widget in all four families with
sample hosts (plus the empty state one timeline click away). Sample state is
fileprivate to the widget files — never in PunktfunkShared.
