## manifest.json shape

Write beside this contract as `.scratch/<run>/reference/manifest.json`:

```json
{
  "schema": "design-playbook.reference.manifest/v1",
  "run_id": "<run>",
  "captured_at": "2026-07-22T00:00:00+08:00",
  "tool": "reference-intake",
  "sources": [
    {
      "id": "src-1",
      "kind": "screenshot",
      "locator": "assets/hero.png",
      "sha256": "<hex or null>",
      "note": "optional"
    }
  ]
}
```

Rules:

- `kind` is one of: `screenshot`, `url`, `design_file`, `product_analogy`, `other`
- file locators are run-root-relative under `reference/` when copied into `assets/`
- URL locators are absolute strings; `sha256` is null for pure URLs and product analogies
- do not put host Fill paths into `sources`
