The 2K color, OpenGL normal, roughness and ambient occlusion maps are bundled locally.
Stadium geometry and grass blades are created in code. The goalkeeper image is generated with the built-in imagegen tool; see ../characters/PROMPT.md.
The user-provided visual reference is https://screen.toys/firewood/; no assets or code from that site are included.
