+/**
+ * StyleX's Vite plugin polls its CSS store every 150ms from `configureServer`
+ * and pushes an HMR event when it changes. It clears that timer from the close
+ * event of `server.httpServer`. Vitest runs the dev server in middleware mode,
+ * where `httpServer` is null, so the timer is never cleared: the run finishes,
+ * the event loop stays awake, and vitest kills the worker after ten seconds with
+ * "something prevents Vite server from exiting". A test needs StyleX's
+ * transform, which is a different hook, and never needs its HMR — so drop this
+ * one hook under vitest and keep the plugin.
+ *
+ * Remove this once @stylexjs/unplugin clears the timer on `buildEnd` or guards
+ * the hook, and check that `npm test` still exits without the warning.
