- Status: computed from connection, presence, hold, relay, player facts; no setters (health writes and HealthStatus gone); pill, strip and source line read it; transitions go to the Notifier. - Notifier: noticeFor(event, context) with self presence, alone, window activity, playing and prefs; toasts for joins/leaves/returns/swaps/ Up next adds (with picture)/problems/chat, the rest logged; while sitting out only chat, nudges, starting, Up next (+ joins if chosen); alone no social notices; replayed lines logged; owns its toast timer. - System notifications (flutter_local_notifications: D-Bus on Linux, WinRT on Windows) when the window isn't focused; a click focuses it. - Toasts sit above the control bar and move with it. - Versions: each member's in the members card and avatar tooltip, the server's in the card header; the strip no longer shows it.
