+Reclass macOS Build Script
+
+Usage:
+  ./scripts/build_macos.sh [options]
+
+Options:
+  --qt-dir <path>       Qt installation prefix (e.g. /opt/homebrew/opt/qt)
+  --build-type <type>   Release | Debug | RelWithDebInfo | MinSizeRel (default: Release)
+  --build-dir <path>    Build directory (default: <repo>/build)
+  --generator <name>    CMake generator (default: Ninja if available)
+  --clean               Remove build directory before configuring
+  --rebuild             Clean then build
+  --package             Run macdeployqt and create a zip
+  --tests               Run ctest after build
+  -h, --help            Show this help
+
+Notes:
+  - You can set QTDIR or Qt6_DIR in your environment instead of --qt-dir.
+  - If Qt is installed via Homebrew, the script will try to detect it.
