LUT library (authoring)

index.json is the agent-consumed catalog of color-grade looks. Each entry resolves on demand — no .cube bodies are committed to the repo.

Each look has:

id, description, tags, intensity — matching + application metadata.
url (optional) — a hosted .cube downloaded, validated, and frozen at resolve time, exactly like bgm/image assets.
params (optional) — a deterministic buildCube spec used offline (--local-only) or as a fallback if the url download/validation fails.

An entry needs at least one of url or params; prefer both (CDN url with a params fallback) so resolution is never blocked on the network.

Hosting a new look (operators)

Generate the .cube (e.g. resolve -t lut --params '{...}' or a graded export).
Upload it to the public CDN origin bucket:
```
aws s3 cp <id>.cube s3://heygen-public/luts/<id>.cube
```
It is then served at https://static.heygen.ai/luts/<id>.cube (CloudFront).
Add an entry to index.json with that url (and ideally a params fallback).
