-`runtime_mode="auto_fused"` is the default optimized runtime. On CUDA it tries the native packed low-bit matmul kernel first, then Triton packed matmul.

+`runtime_mode="auto_fused"` is the default optimized runtime. On CUDA, the `kernels` extra provides the Triton packed fallback; a locally built native CUDA package is preferred automatically when installed. On MPS, build and install the native Metal package from the OrbitQuant source tree. See the [OrbitQuant runtime instructions](https://github.com/iamwavecut/OrbitQuant#native-packed-kernels).
