-# AI Usage Policy
-
-This project has strict rules for AI usage:
-
-* **The human-in-the-loop must fully understand all code.** If you
-can't explain what your changes do and how they interact with the
-greater system without the aid of AI tools, do not contribute
-those changes.
-
-* **Issues and discussions can use AI assistance but must have a full
-human-in-the-loop.** This means that any content generated with AI
-must have been reviewed *and edited* by a human before submission.
-The author must do their research and trim this down.
-
-* **No AI-generated media is allowed (textures, videos, audio, etc.).**
-Text and code are the only acceptable AI-generated content, per the
-other rules in this policy.
-
-* **Commit messages, PR descriptions must read in your own voice.**
-No AI-authored or AI co-authored commits, including Co-authored-by AI tags.
-
-* **Only contribute fixes for bugs you have personally hit in-game.**
-If you haven’t experienced or reproduced a bug firsthand, and don’t
-already know the relevant code well, don’t throw AI at it and forward it to us.
-Patches written for problems the author never actually experienced themselves
-tend to fix the wrong thing and/or produce another.
-
-* **The voice and intent of written content must be yours.**
-For documentation and especially quests, the tone and the point you're trying to make
-has to come from you, not an AI. Use AI to help with phrasing or cleanup if you like,
-but if the substance and voice aren't yours, don't contribute it.
-
-* **Bad AI use may be blocked.** People who produce bad contributions
-that are clearly AI (slop) may be blocked from making future contributions.
-We love to help junior developers learn and grow, but if you're interested
-in that, don't use AI and we'll help you. We're sorry that bad AI
-users have ruined this for you.
-
-
-## There are Humans Here
-
-Please remember that this project is maintained by humans.
-
-Every discussion, issue, and pull request is read and reviewed by
-humans (and sometimes machines, too). It is a boundary point at which
-people interact with each other and work is done. It is rude and
-disrespectful to approach this boundary with low-effort, unqualified
-work, since it puts the burden of validation on the maintainer.
-
-In a perfect world, AI would produce high-quality, accurate work
-every time. But today, that reality depends on the user of the AI.
-And today, many users of AI do not use it well. So, until that
-changes, we need to have strict rules to protect maintainers.

+ *       Requires you to enable usesShadowedDependencies in gradle.properties
+ *

+ *
+ * You can exclude transitive dependencies (dependencies of the chosen dependency) by appending { transitive = false } if needed,
