This project does NOT use AI-generated 2D or 3D assets (images, 3D models, 2D art, icons and etc). All icons and other visual materials were either created by me or come from open-source resources. A full list of third-party assets is provided below in CREDITS section and is also available in the program under the "Help -> About Brushwork" section.

This software is NOT a product of vibe coding. AI-assisted tools were used only as an additional help and aid during code development.
