# Crescendo credits and third-party notices ## Crescendo Copyright (c) 2026 starrabb1t. Original Crescendo code, documentation, artwork, and fonts are covered by the proprietary terms in [`LICENSE`](LICENSE), except where this file or a notice alongside a file says otherwise. Asset provenance: - the twelve heraldic SVGs in `static/assets/icons/emblems/` were vectorized from OpenAI-generated images, selected and art-directed by starrabb1t for Crescendo; they are original project artwork under the terms above; - the landscape PNG illustrations were generated for Crescendo with OpenAI GPT Image under the direction of starrabb1t; - all 35 biome SVGs were drawn by starrabb1t; - all 16 settlement SVGs and their templates were drawn by starrabb1t; - the unit SVGs and their templates were drawn by starrabb1t; - the game status-mark SVGs were drawn by starrabb1t; - the three large filled illustrations `orders`, `diplomacy`, and `armies` were drawn by starrabb1t; - the Neume and Cartula display fonts were drawn by starrabb1t and are built from the source skeletons in `tools/fonts/`. OpenAI and GPT are trademarks of OpenAI. Their mention describes the tool used to create the landscape images and does not imply authorship, sponsorship, or endorsement. ## Inspirations and acknowledgements Crescendo's original implementation and materials were created independently, with creative influence from the following works: - Amit J. Patel's [Mapgen2 Procedural Island Map Generator](https://www.redblobgames.com/maps/mapgen2/) at Red Blob Games inspired the procedural map-generation project and parts of its visual language. Crescendo's map generator was implemented independently; no Red Blob Games code or assets were copied into the project. - [Territorial.io](https://territorial.io/) inspired some of Crescendo's high-level game mechanics. - [Knights and Merchants: The Shattered Kingdom](https://en.wikipedia.org/wiki/Knights_and_Merchants:_The_Shattered_Kingdom) inspired aspects of Crescendo's mood and atmosphere. These references acknowledge creative influence only. Unless separately identified under **Third-party materials**, no code, artwork, text, audio, or other assets from these works are included in Crescendo. All titles and trademarks belong to their respective owners; no affiliation or endorsement is implied. ## Third-party materials ### Browser libraries | Material | Files | Version / identification | License | | --- | --- | --- | --- | | [Delaunator](https://github.com/mapbox/delaunator) | `static/js/vendor/delaunator.min.js` | vendored build; the file contains no upstream version marker | ISC | | [robust-predicates](https://github.com/mourner/robust-predicates) | bundled in `delaunator.min.js` | Delaunator dependency | Unlicense | | [lil-gui](https://github.com/georgealways/lil-gui) | `static/js/vendor/lil-gui.umd.min.js`, `static/css/lil-gui.css` | 0.20.0 | MIT | | [poisson-disk-sampling](https://github.com/kchapelier/poisson-disk-sampling) | `static/js/vendor/poisson-disk-sampling.min.js` | 2.3.1 | MIT | | [moore](https://github.com/hughsk/moore) | bundled in `poisson-disk-sampling.min.js` | 1.0.0 | MIT | | [simplex-noise.js](https://github.com/jwagner/simplex-noise.js) | `static/js/vendor/simplex-noise.js` | 2.4.0 | MIT | | [Socket.IO client](https://github.com/socketio/socket.io-client) | `static/js/vendor/socket.io.min.js` | 4.7.5 | MIT | The vendored files remain under their upstream licenses.

Their upstream license and notice files are retained in each installed distribution. `uv.lock` is the authoritative version inventory for a particular source checkout. The deployment image also copies `uv` from the official Astral container image to install the locked Python environment. `uv` is distributed under the Apache License 2.0 or MIT License, at the user's option. ### Deployment environment The application image is based on the official `python:3.12-slim-bookworm` image. CPython is distributed under the Python Software Foundation License; its complete license is retained in the image at `/usr/local/lib/python3.12/LICENSE.txt`. Debian package copyright and license files remain under `/usr/share/doc/`. The Compose deployment references the official `nginx:1.28-alpine` and `certbot/certbot:v5.7.0` images.
