## Data and privacy
Feed: `screenrig.bikeshare/v1`.

## 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.
