// gpu_fwd.hpp — the one place the GPU device types are forward-declared.
//
// Where the device layer is gpu-runtime's (PULP_GPU_RUNTIME, set on
// pulp::platform by tools/cmake/PulpGpuRuntime.cmake), pulp::render::GpuSurface
// names gpu_runtime::GpuSurface, so a hand-written `class GpuSurface;` in
// pulp::render would declare a second, unrelated class. Headers that need these
// names without their definitions include this instead; it depends on nothing,
// so it lives where every consumer already looks. core_vellum_direction.py
// refuses a raw forward declaration of them anywhere else.
