3. unpopped A vendor-neutral kernel generator: the backend-agnostic IR, plan, transform pipeline, contracts and dispatch artifacts, plus the `Backend` and `Compiler` traits a target implements. Ships a portable-C99 reference backend and a CPU oracle, so it builds and self-tests with no device, no driver, and no vendor dependency. Device backends live under their own vendor identity and depend on this crate — the CUDA emitter, its NVRTC compiler and the Fuel synthesizer live in `baracuda-cuda-emit`.
