// 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) and the lyrics-cache row.
//
// Still missing: the whole OFFLINE CACHE group (Open manager / Open folder /
// Clear all). What blocks it is the MANAGER VIEW, which has no Qt counterpart
// yet — not the engine: `offline_cache_qt.rs` already runs the downloads from
// the album page and the track row.
