## Long–Evans rat pose artwork

- Credit / licensor: [zhang-mengjia](https://github.com/zhang-mengjia)

- License: [Creative Commons Attribution 4.0 International](https://creativecommons.org/licenses/by/4.0/), under the project's separate rat artwork license.
- Asset: `rats/poses.json`, containing native cubic paths for standing, walking, rearing, sniffing and sitting.
- Provenance: five transparent PNGs supplied by the project owner from the 大鼠素材 directory, replacing the previous single vector rat. The supplied files were named `ChatGPT_图像_2026年10月12日_19_48_25-1.png` through `ChatGPT_图像_2026年10月12日_19_48_30-5.png`. Number 1 is walking, 2 rearing, 3 sniffing, 4 sitting and 5 standing.
- Preparation: the five poses are redrawn as cubic vector paths in the warm neutral style supplied in `example.pptx`. Muted black and white fur and pale pink skin replace the previous saturated fills. Silhouettes, pose identity and floor anchors are retained; internal fur, skin and detail paths remain separate. This is adapted artwork under the same attribution requirement.
- Export: PPTX includes native editable freeform shapes in a Rat group. PDF and SVG contain vector rat paths. PNG and clipboard exports rasterize the shared vector scene.

The rat artwork is licensed separately from the MIT application code. This license also applies to the rat artwork included in exported PPT, PDF, SVG and PNG figures and in screenshots of this application.

## Other graphics

The chamber style reference was supplied by the project owner in `example.pptx`. Its original shell, lamp, speaker perforations, lever and cup curves are reused in `reference-parts.json`; source package and SVG hashes are recorded there. The remaining module drawings and floor patterns follow that palette. Application code, floor patterns, module drawing code and favicon use the project's MIT license. The blank PowerPoint package was generated with Artifact Tool and contains no stock imagery or embedded fonts; it is included under the project's MIT license.
