Project artwork and examples

LuaBill3D.icoChatGPT — source reported by project ownersProject artwork; see provenance note below
Max_Mustermann.png; Musterfirma_GmbH.pngProbably ChatGPT; edited in GIMP 3.0.4; exact generation records unconfirmedSample artwork; see provenance note below

Artwork provenance was reported by the project owners: the icon was generated with ChatGPT; the two PNG examples are believed to have the same origin, but their exact generation records have not been confirmed. PNG metadata records editing in GIMP 3.0.4, not an author or an image license. ChatGPT and GIMP are tools named for provenance; they are not identified as copyright holders. No third-party stock-image license has been established for these samples.

Details and original notices

Versions describe the audited Windows release, not a requirement to use exactly these external-tool versions. A notice cache can include Qt components that are not shipped. The original license texts control; this index is an attribution guide, not a guarantee about every historical code fragment or user-supplied asset.
