--dashboard defaulted to looping mock STT forever, so the status page piled up thousands of fake "conversations" (all mock, 0ms, same reply) that looked like real traffic. Now it plays 3 sample utterances then idles; a loud 데모 모드 banner states the turns are mock samples, not real STT/Brain/TTS. Continuous demo moved behind --dashboard-loop-demo.
