-name: wgpu sanity (macOS)

-# Lightweight compile-only check for the wgpu backend on macOS. Skips the
-# IfcViewerWgpuMinimal executable (its surface creation has no Metal path
-# yet — see task #32) and just confirms IfcViewerWgpu links and the pure-
-# CPU state tests pass.
-#
-# Goal: catch portability regressions in the wgpu source on Apple Silicon
-# / Intel Mac without needing the full IfcGeom + OCCT + Python toolchain
-# that build_osx.yml carries. Runs in ~5 minutes.
