// Vendored from google/highway hwy/per_target.cc at commit:// 66486a10623fa0d72fe91260f96c892e41aceb06//// Local modifications:// - Changed HWY_TARGET_INCLUDE from the upstream path to the local vendored// filename so Highway's multi-pass include machinery resolves this copy.// - Left the implementation otherwise identical to upstream.//// Why:// - Ghostty vendors only the specific Highway .cc files it needs in this// directory, so the original source-relative include path no longer exists.// - Keeping the logic unchanged aside from the include path reduces fork// maintenance cost while still allowing a minimal vendored source set.
