Why doesn't Card display below View (Svelte)

I have the following app.svelte:

<App {...f7params}>
  <View main url="/" browserHistory browserHistorySeparator="#" />
         Test content

The stuff in the <View> loads fine, but the <Card> below doesn’t display. I see it in the DOM with inspect element. Am I missing some basic F7 layout concept?

Well after more search, the full docs at https://framework7.io/docs/view.html clearly say “Only 1 view is allowed!”
