"""Neuron (Trainium) support: device mapping and pure-torch kernel implementations.

``vendor/`` holds drop-in packages for the kernel libraries DeepInfer imports
(deep_gemm, flash_mla, deep_ep, deep_select, tile_kernels, tilelang); they follow
the Ascend API variants and are written in device-agnostic torch so the same code
runs on the ``neuron`` device and, for correctness work, on the host.
