## What it does

This slash command prepares Storybook for a SvelteKit project. It can start setup with `npx storybook@latest init` or guide a manual configuration using `@storybook/sveltekit`, Svelte CSF, accessibility, and interaction addons.

The command creates `.storybook/main.js` and `.storybook/preview.js`, imports `src/app.css`, discovers stories under `src/**/*.stories.@(js|ts|svelte)`, and serves files from `../static`. It also lays out component stories under `src/lib/components` and documentation stories under `src/stories`, then adds Storybook and Chromatic scripts.

The generated configuration points to `../static`, so the project needs that static-assets directory in its expected location. Manual setup also covers module mocking, path aliases, and SvelteKit SSR considerations.
