/** \defgroup GPU_Module GPU module
 *
 * GPU-accelerated solvers and operations using NVIDIA CUDA libraries
 * (cuSOLVER, cuBLAS, cuSPARSE, cuFFT, cuDSS).
 *
 * This module provides explicit GPU solver classes that coexist with Eigen's
 * CPU solvers. Unlike the LAPACKE dispatch (which replaces the CPU
 * implementation globally), GPU classes are separate types the user
 * instantiates by choice:
 *
 * \code
 * #define EIGEN_USE_GPU
 * #include <Eigen/GPU>
 *
 * // CPU path (unchanged)
 * Eigen::LLT<Eigen::MatrixXd> llt_cpu(A);
 *
 * // GPU path (explicit)
 * Eigen::GpuLLT<double> llt_gpu(A);   // L stays on device
 * auto X = llt_gpu.solve(B);          // only B transferred per solve
 * \endcode
 *
 * Requires CUDA 11.4+. See CLAUDE.md.
