//! Concrete STT/TTS provider implementations.
//!
//! Local providers (sherpa-onnx STT/TTS) are gated behind the
//! `voice-sherpa` cargo feature so the default build doesn't pay
//! sherpa-onnx-sys's C++ compile cost. Mock providers and the
//! OpenAI TTS client (HTTP-only, works against the public endpoint
//! or any self-hosted server that speaks the same shape) are
//! always available.
