## Bundled ArgyllCMS sidecar binaries

This application bundles and invokes command-line binaries from the Gronod fork of ArgyllCMS. Those binaries are licensed separately under the **GNU Affero General Public License v3 (AGPLv3)**. They are executed strictly as independent subprocesses — they are never linked, loaded, or incorporated into this application — and a copy of `License.txt` is shipped beside the binaries in `Resources/Argyll/`. The terms above apply only to the ICCery application source code, not to the ArgyllCMS binaries.
