T8b949e/**

* Records microphone input as 16-bit PCM and returns a WAV Blob.

*

* Produces a self-contained WAV/PCM payload (Float32 samples captured via

* Web Audio, downmixed to mono and quantised to int16) so the backend can

* encode the audio to OGG/Opus using LXST's OpusFileSink without relying

* on ffmpeg or any browser MediaRecorder container output.
