+# Build a universal EternalTerminal `et` client on macOS (arm64 + x86_64).
+#
+# Inputs (env):
+#   ET_REF   — git ref of MisterTea/EternalTerminal to build (e.g. et-v6.2.10)
+#   OUT_DIR  — directory to write et-darwin-universal.tar.gz + sha256
+#   MACOSX_DEPLOYMENT_TARGET — min macOS (default 11.0)
+#
+# Output:
+#   $OUT_DIR/et-darwin-universal.tar.gz          (single universal `et`)
+#   $OUT_DIR/et-darwin-universal.tar.gz.sha256
+#
+# Builds each arch separately (vcpkg arm64-osx / x64-osx static triplets) and
+# lipo-combines the two `et` binaries. Links only macOS system dylibs.
