+ * Tailwind CSS v4 (via @tailwindcss/vite) automatically sets up all required
+ * PostCSS plugins — you do NOT need to include `tailwindcss` or `autoprefixer` here.
+ *
+ * This file only exists for adding additional PostCSS plugins, if needed.
+ * For example:
+ *
+ * import postcssNested from 'postcss-nested'
+ * export default { plugins: [postcssNested()] }
+ *
+ * Otherwise, you can leave this file empty.
