B7 (Jun 18 2026): user reported Settings page unresponsive when reached via the ChatScreen topbar gear icon, but worked fine via the drawer sidebar. Two fixes: 1. Route topbar gear through NavigationController.navigateTo() instead of raw backStack.add(). The NavigationController path (used by the drawer) deduplicates against the current top entry and matches the drawer's navigation flow exactly. The bypass path could stack duplicate SettingsScreen entries on rapid taps, which likely caused the unresponsive symptom. 2. Add 'Clear Token' OutlinedButton below the Auth Token field in Settings. One-tap wipes a corrupted / rejected token and saves immediately, without having to select-and-delete the masked password field character by character. Recovers from the 'I gave you a bad token' scenario in seconds.
