//! Grok Real-Time Voice provider (API access pending).
//!
//! This module provides a skeleton for xAI's Grok real-time voice capabilities.
//! Grok offers conversational AI with real-time voice interaction.
//!
//! # Status
//!
//! API access is currently pending approval from xAI.
//! Expected availability: Q1 2026 (pending partnership).
