3. TypeScript

Copyright (c) Microsoft Corporation.

Licensed under the Apache License, Version 2.0 (the "License");
see LICENSE at the project URL above for the full text.

TypeScript is used only at build time; its runtime redistribution is limited to the emitted JavaScript (which is the developer's own code).

4. Vite

The MIT License (MIT)

Copyright (c) 2019-present, VoidZero Inc. and Vite contributors

Permission is hereby granted, free of charge, to any person obtaining a copy
of this software and associated documentation files (the "Software"), to deal
in the Software without restriction, including without limitation the rights
to use, copy, modify, merge, publish, distribute, sublicense, and/or sell
copies of the Software, and to permit persons to whom the Software is
furnished to do so, subject to the following conditions:

The above copyright notice and this permission notice shall be included in

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND.

Vite is used only at build time; its runtime footprint is zero.

5. pngjs

Copyright (c) 2015 Kuba Niegowski

Permission is hereby granted, free of charge, to any person obtaining a copy
of this software and associated documentation files (the "Software"), to deal
in the Software without restriction.

pngjs is not shipped with the game — it runs only in the developer's build environment to preprocess PNG assets. It is listed here for completeness and in case a future build inlines it.

6. @types/pngjs

Type definitions only; no runtime footprint.

7. Fonts & Icons

Current build uses no bundled fonts. The game renders with the user's system default UI font stack (-apple-system, Segoe UI, etc.) and procedural glyphs generated at runtime. This section will be updated when the art pass adds a bundled display font.

8. AI-assisted development

This project was developed with the assistance of large-language-model pair-programmers (Anthropic Claude, OpenAI GPT, Google Gemini, integrated via the Cursor IDE). The resulting code, narrative, and design are the Author's work — the Author reviewed, approved, and accepted responsibility for all committed content. LLM assistance is not a licensed dependency and does not confer any rights on the model vendors.

How this file is kept in sync

Whenever a new npm dependency is added that ships to end users, this file must be updated with:

  1. The project name, URL, and version range.
  2. The license identifier (SPDX when possible: MIT, Apache-2.0, etc.).
  3. A reproduction of the license text (or a verbatim link to it plus the NOTICE file for Apache-2.0 deps).

For Steam submissions, this file (or a distilled version) must be embedded in the game's "Credits · Legal Notices" screen and accessible to any player without requiring network access.
