Intake Checklist
- Prefer CC0 for assets that ship inside the repository.
- Use Pixabay assets only when the model is integrated into the game and not redistributed as a standalone asset pack.
- Avoid logos, trademarked markings, recognizable characters, or assets based on protected IP.
- Record the source URL, author, license, and download date before adding binary assets.
- Keep runtime assets lightweight: GLB when possible, compressed textures, and simple collision geometry.
