Comienza con src/components/demo.FormComponents.tsx en el ejemplo enlazado de tanstack-dashboard e inspecciona el import no resuelto de #/components/ui/button. Ejecuta npm run build, reproduciendo la ruta de despliegue de Cloudflare descrita en el issue. Se considera terminado cuando el dashboard SaaS se compila correctamente sin el error de resolución de imports de Vite.
