//! Groq text-to-speech backend.
//!
//! Groq's `/openai/v1/audio/speech` endpoint speaks the OpenAI request shape,
//! so a Groq backend is just an [`OpenAiCompatTts`] pinned to the Groq base
//! URL. The base URL is shared with [`super::create_backend`]; this module
//! also offers a named constructor for clarity and tests.

/// Groq API endpoint for text-to-speech.

/// Build a Groq TTS backend (an [`OpenAiCompatTts`] pinned to Groq). Groq
/// always requires an API key.
