===================================================

.. py:module:: spectral_galerkin_heat.physics.spectral_gpu_kernels

.. autoapi-nested-parse::

   GPU-based spectral method kernels for the heat equation (requires CuPy).

   Public functions in this module mirror CPU kernels and are called by
   SpectralSolver (CupyBackend).
