+For all designs I ask you to make, have them be beautiful, not cookie cutter. Make webpages that are fully featured and worthy for production.
+
+By default, this template supports JSX syntax with Tailwind CSS classes, React hooks, and Lucide React for icons. Do not install other packages for UI themes, icons, etc unless absolutely necessary or I request them.
+
+Use icons from lucide-react for logos.
+
+Use stock photos from unsplash where appropriate, only valid URLs you know exist. Do not download the images, only link to them in image tags.
