/**
 * Live transcription hook — runs the browser's Web Speech API alongside
 * any recording to produce an instant transcript with no API key required.
 *
 * Designed to pair with a MediaRecorder: start when recording begins,
 * stop when the user hits stop. The accumulated transcript is available
 * immediately — no round-trip to Whisper needed.
 *
 * Builder can transcribe the original recording afterward if native capture
 * produces no text, but this gives users something useful from second zero
 * without a cloud transcription request.
