//! Output audio encoding: f32 PCM samples → wire bytes.
//!
//! Closes #223. Adds OGG/Opus (the format Telegram, WhatsApp, Signal, and
//! Discord render as native voice messages) and FLAC (lossless, royalty-free,
//! browser-universal incl. Safari) alongside the original WAV. Keeps the door
//! open for `mp3` / `raw-pcm` later.
