Wrapper

Not supported yet.

The Vue plugin lets a setup file add components that render around every story with addWrapper. The Svelte plugin has no equivalent: there is no addWrapper, and Hst.Story and Hst.Variant have no meta prop for a story to opt out with.

This is tracked in #232.

What to do instead

For a wrapper you want around one story, wrap the markup yourself:

<script lang="ts">
  import type { Hst } from '@poveste/plugin-svelte'
  import MyComponent from './MyComponent.svelte'
  import ThemeProvider from './ThemeProvider.svelte'

  export let Hst: Hst
</script>

<Hst.Story title="MyStory">
  <ThemeProvider>
    <MyComponent />
  </ThemeProvider>
</Hst.Story>

For something every story needs — a CSS import, a global store, a locale — the setup file still runs, so anything that does not need to render around the component belongs there.

What the setup file cannot do is put an element in the tree above each story. That is the gap.
