./build.sh release builds into build-release/ with --buildtype=release and strips the binary in place (meson's strip only applies on install), yielding a ~270KB binary for size benchmarking against distro compositors like labwc. The default ./build.sh debug path and the build/ tree used by the test suite are untouched.
