/**
 * AudioSpeech — hosted text-to-speech for the browser SDK.
 *
 * Mirrors OpenAI's ``client.audio.speech.create(...)`` shape. Posts to the
 * hosted ``{base}/audio/speech`` endpoint where ``{base}`` is the canonical
 * hosted root (``https://api.octomil.com/v1``) and returns the raw audio
 * bytes as a Blob plus Octomil routing metadata surfaced via ``X-Octomil-*``
 * response headers.
 *
 * v0.10.0 hosted API cutover: legacy control-plane bases (``/api/v1``)
 * are rejected at construction time; no silent normalization.
