Rainbow Herd agent contract

Role

Rainbow Herd is the primary unicorn-and-rainbow game.

Tiny Unicorn Lab dependency

• vendor/tiny-unicorn-lab is the only unicorn anatomy source.
• Import its public module and keep the submodule pinned to an exact commit.
• Do not add copied geometry arrays, placeholder creatures, or fallback anatomy.
• Herd batching and animation belong here; anatomy and character parts do not.
• A dependency update must record the upstream commit and resulting ZIP size.

Competition guardrails

• Keep the submission ZIP at or below 13,312 bytes.
• Use only the official 2026 A-Frame exception as an external asset.
• Preserve WebXR and pointer/touch fallback behavior.
• Run the gameplay and competition tests after shared-geometry changes.

Optimization priority

• "Memory budget" in this project means compressed competition ZIP bytes unless the user explicitly says runtime RAM.
• Optimize for player experience within the ZIP cap. Measure archive changes; never infer competition headroom from runtime array, texture or geometry sizes.
• Do not reject generated detail, textures or engine-default resources solely for using more RAM. Evaluate frame time, startup and stability separately with evidence; preserve useful batching and interaction safeguards.
