// Settings > Offline — two explicitly-titled groups (the Tauri tab hid
// this boundary; the owner endorsed the split):
//
//  - OFFLINE MODE — the app operating without Qobuz: tri-state status row
//    (online / no connection / induced) with an honest "Check now"
//    re-probe, the persisted Enable Offline Mode toggle (#279 stream-first
//    snapshot handled by the shared engine), and the network-folders
//    policy toggle (mounted only while induced is on, Tauri parity).
//  - OFFLINE CACHE — downloads: manager launch + open-folder / clear-all.
//    The Local-Library rows (show-in-library, repair) arrive with the
//    Local Library port.
//
// Same structure as the other settings panels (GroupHeader + SettingRow +
// SecondaryButton). Toggle changes bubble through settings-bool; the
// status row reads the live OfflineState global; the panel's init
// re-seeds the toggle states from the engine store (OfflineModeActions).
