Third-Party Licenses

This document lists third-party software components that are used by, included in, or distributed with this project and its build artifacts.

Each component is subject to its own license terms. The licenses for these components are reproduced in the LICENSES/ directory where required.

Where applicable, the original copyright notices and license texts have been preserved in the corresponding source files or documentation.

The presence of a component in this list does not necessarily mean it is included in every build or release of the software. Some components may be used only during development, testing, or for specific platform targets.

This document is provided to help users identify the licenses governing third-party code that may be included in this project or its distributed artifacts.
