//! WarzonePhone Codec Layer
//!
//! Provides audio encoding/decoding with adaptive codec switching:
//! - Opus (24kbps / 16kbps / 6kbps) for normal to degraded conditions
//! - Codec2 (3200bps / 1200bps) via C bindings for catastrophic conditions
//!
//! ## Usage
//!
//! Use the factory functions [`create_encoder`] and [`create_decoder`] to get
//! trait-object encoders/decoders that handle adaptive switching internally.
