/**
 * @file meshx_model_ctl.hpp
 *
 * @brief Header file for MeshX Light CTL Models
 * This file contains the declarations and definitions for the MeshX Light CTL Models,
 * including the Light CTL Server and Client models for color temperature and lightness control.
 *
 * Key Features:
 * - Implements Bluetooth SIG-defined Light CTL model
 * - Inherits from meshXServerModel and meshXClientModel templates
 * - Provides standard Light CTL control operations (lightness, temperature, delta UV)
 * - Integrates with MeshX transmission control
