import SwiftUI

/// Purpose: Advanced tab — diagnostics toggle, re-open onboarding, settings export /
///          import / reset, and version footer.
///          Extracted from PreferencesView to keep every tab file under 500 lines.
/// Inputs:  @AppStorage for diagnostics; injected closures for the three settings-file
///          actions and the onboarding re-open; a Binding for hasPassword so Reset can
///          refresh it without coupling to the parent's @State directly.
/// Outputs: writes to UserDefaults (via the closures); no direct coordinator calls.
/// Constraints: @MainActor (SwiftUI). Reset/Export/Import are defined in the parent
///          PreferencesView and passed in as closures so the exportableKeys list stays
///          in one place.
/// SPORT: MASTER-PREFS
