/**
 * @deprecated Legacy Tailwind v3 preset.
 *
 * The framework has moved to Tailwind v4. Templates should now use the shared
 * stylesheet from CSS instead of a `tailwind.config.ts`:
 *
 *   // app/global.css
 *   @import "tailwindcss";
 *   @import "@agent-native/core/styles/agent-native.css";
 *
 * No `tailwind.config.ts` or `postcss.config.js` is needed. The
 * `@tailwindcss/vite` plugin is auto-injected by `defineConfig()`.
 *
 * This export is kept only for third-party templates still on the v3 PostCSS pipeline.
