// Settings > Offline — the QML port of crates/qbz-ui/ui/settings/
// OfflineSettings.slint.
//
// OFFLINE MODE (the app running without Qobuz) is the shared engine: the
// status line reads the LIVE QbzSession properties the engine forwarder
// publishes (tri-state online / no connection / induced + captive portal),
// and the toggle rides settingsBool("offline-mode-enabled") into
// `OfflineModeEngine::set_induced` (which also takes the #279 stream-first
// snapshot).
//
// "Check now" IS shipped (`offline-recheck`); so is the live tri-state status
// line (QbzSession.offlineMode / captivePortal).
//
// OFFLINE CACHE (Open manager / Open folder) is the downloads half and lives
// here too. Purging the whole cache is the manager's own trash glyph, with a
// tooltip and an explicit modal (OfflineManagerView.qml) — one destructive
// entry point, not two. The artwork and lyrics caches live in Settings >
// Storage (StorageSettings.qml) since 2026-09-13.
