Detailed Description

Backend-specific implementation layer for EulerP Evaluator kernel dispatch.

Defines Evaluator_impl, a template struct parameterized by DeviceBackend (Host or CUDA). For each Evaluator kernel, an inner argument struct wraps the host-side shared_ptr-based Evaluator::*_Arg into device views suitable for kernel execution. The inner Portable sub-struct is trivially copyable and can be passed to CUDA kernels.

Also defines helper macros for constructing device views from Evaluator argument members.
