  # ── Windows x86_64 GNU cross-compiled from Linux ──────────────────────────────
  #
  # This job validates that the crate compiles for the windows-gnu target when
  # cross-compiled from a Linux host using MinGW-w64.  It does not run tests
  # (cross-execution would require Wine), but the compile step is sufficient to
  # catch ABI / link-flag regressions early.
