// The shell's sustained-failure banner must name the actual
// problem: a hub that rejects the token (UNAUTHENTICATED /

// needs attention. The probe result is faked through
// StudioShellState.debugProbeOverride; the banner appears after
// three consecutive failed polls (5 s apart), so each test pumps
// the poll timer forward instead of waiting.
