`acrylic-keychain-large` revision `1` produces one 3 × 2.125 inch keychain per
quantity.

| Required role | Exact ratio | Example prepared pixels |
| ------------- | ----------- | ----------------------- |
| `front`       | `7:5`       | 2100 × 1500             |

```json theme={null}
{
  "product": { "id": "acrylic-keychain-large", "revision": 1 },
  "quantity": 1,
  "assets": [
    { "role": "front", "url": "https://cdn.example.com/orders/large-front.jpg", "pixel_width": 2100, "pixel_height": 1500 },
    { "role": "back", "url": "https://cdn.example.com/orders/large-back.jpg", "pixel_width": 2100, "pixel_height": 1500 }
  ]
}
```

The large keychain’s landscape `7:5` contract is distinct from the small
keychain’s `4:5` contract. Prepare each side independently.
