 This command installs `electron-builder` on demand via `npx` for packaging, rather than during every local dependency install.
 
+## macOS arm64 (source release workflow)
+
+If macOS runners are unavailable in CI, publish the `5ET-D-macos-arm64-source-*` artifact and have Apple Silicon users build locally:
+
+```bash
+./build-macos-arm64.command
+```
+
+Equivalent CLI command:
+
+```bash
+./scripts/build-macos-arm64.sh
+```
+
+This builds a macOS arm64 package and writes output to `release/`.
