 * Vite plugin that serves the widget preview route.

 * Dev mode: serves `/__preview__` by transforming preview.html through
 * Vite's HTML pipeline (so import resolution and HMR work).
 *
 * Build mode: adds preview.html as a second Rollup input so `vite build`
 * produces it alongside index.html for production deployment.
