	125	+ * `generateContent` call as an `inline_data` part beside a text instruction,
	126	+ * and the model returns the transcript as its answer. Inline data is base64,
	127	+ * which inflates the payload by roughly a third; the caller caps media at
	128	+ * 15 MB for this platform so the request stays inside Gemini's inline
	129	+ * ceiling. (Files API upload would lift that, and is the obvious next step
	130	+ * if longer recordings are ever needed.)
