  <!--
    Available shirts, maps unique identifier to {color, image}. Sizes are fetched remotely.

    When a shirt color is selected, `selected.id` changes which causes this
    <amp-state> to perform an XHR to the new [src] value. Upon completion,
    the XHR response is merged into the state under its "id" attribute ("shirts").

    This has the limitation that data returned by the XHR must have the same
    hierarchical structure as the existing data.

    For example, the XHR must return something like:
      {
        "3": {
          "sizes": ["S", "L"]
        }
      }

    By contrast, it must NOT return something like:
      {
        "sizes": ["S", "L"]
      }

    In order to support the latter, we'd need to:
      - Add support for a new action event, AND
      - Force quotation marks for literal keys, AND
      - Reintroduce variables in object keys (removed in #7582)

    <amp-state [src]="..." on="fetch:AMP.setState({"shirts": {selected: {id: event.response}}})"

    Note that shirt with ID == "0" contains size data (but other IDs don't)
    because it's the default shirt color at page load. Size data for other shirts
    will be fetched via XHR when their corresponding colors are selected.
