# The steps of WAI's packaging extension that a GPU computes exactly, as WGSL compute
# kernels through wgpu (shown exact on Metal only; Vulkan and DX12 built, not run): the
# integer encoder's motion search, the
# sum of squared differences, and BLAKE3's chunk function. Every kernel is integer, in
# 32-bit words, so a device that runs it gives the CPU's result for every input
# (extensions/packaging.md §11.6).
#
# A SEPARATE crate with its own lockfile, as wai-ops-gpu is, so that wai-pack builds
# without wgpu by default; wai-pack's `gpu` feature is the only way it enters a pack.
