# Universal binary: build each arch on its own and lipo them together, so one .app
# runs natively on both Apple Silicon and Intel. `swift build --arch a --arch b` would
# do it in one go, but that path needs xcbuild from a full Xcode; --triple works with
# the Command Line Tools alone.
#
# The triple carries the deployment target, so a bundle built on a newer Mac still
# runs on Ventura. Check with `otool -l bin/amm.app/Contents/MacOS/amm | grep -A3 LC_BUILD_VERSION`.

# Rasterises appInfo/icon.svg into appInfo/icon.icns and checks that the menu bar
# artwork is pure black plus alpha. Deliberately not a dependency of build: that would
# demand an SVG on every build and re-rasterise each time.
