  // tap to record, tap again to stop → file attached + sent automatically.
  // The server-side audio_attachment_processor in routes/transcribe.py
  // transcribes it so text-only models can read voice messages.
  //
  // Strategy: replace #btnMic onclick handler (set by boot.js) with our own
  // MediaRecorder flow. Programmatically inject the recorded File into
  // #fileInput via DataTransfer + dispatch change event (boot.js's onchange
  // calls addFiles automatically). Then click #btnSend to submit.
