Conversation playground: - Live speech preview: MediaRecorder sends accumulated audio to /api/transcribe-bytes every 2.5 s; interim Whisper result shown in the text input field while recording. Web Speech API tried first as a faster path when available (HTTPS/localhost). - VAD auto-stop: AudioContext AnalyserNode measures RMS every frame; auto-stops after 1.5 s silence with a visible countdown. Auto-stop toggle to revert to click-to-stop. - Hands-free mode: mic auto-restarts after the agent finishes speaking via audio.ended event + generation-counter cancellation. Hands-free toggle (on by default) to disable. Navigation: - Persist active section and sub-page in localStorage; hard-reload returns to the same page instead of always jumping to My Voices.
