+# Wrap the built desktop binary in a minimal `OpenPencil.app` so
+# macOS shows the proper Dock name + icon.
+#
+# A bare binary (`target/release/openpencil-desktop`) has no
+# `Info.plist`, so the Dock falls back to the raw executable name
+# and a generic icon. Running the binary from *inside* a `.app`
+# directory makes macOS pick up the bundle's `CFBundleName` + icon
+# even without `cargo bundle`.
+#
+# Usage: tools/bundle-macos.sh   (after `cargo build -p op-host-desktop --release`)
+# Then run: target/release/OpenPencil.app/Contents/MacOS/openpencil-desktop
