"""
Tests for cross-platform audio/voice media routing.

These tests pin the expected delivery path for audio media files across
Telegram (where Bot-API sendAudio only accepts MP3/M4A and .ogg/.opus
only renders as a voice bubble when explicitly flagged) and via
``GatewayRunner._deliver_media_from_response``.
