## Data and privacy

Feed: `screenrig.lunch/v1`.

Feed documents carry source attribution. The Player supplies the feed to the card.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `""` | maxLength: `40` | Empty reads School lunch (School breakfast, School snack). |
| `school` | string | `""` | maxLength: `60` | Shown beside the title. A feed's school name fills it when empty. |
| `meal` | string | `"lunch"` | `"breakfast"`, `"lunch"`, `"snack"` |  |
| `count` | integer | `4` | minimum: `1`; maximum: `6` | Days listed after the featured day. |

| --- | --- | --- | --- | --- |
