+
+Luma is a new foundation for your next app. It gives components softer surfaces, more open spacing, and a calmer visual rhythm while keeping the same shadcn/ui workflow.
+
+Like the other new styles, Luma goes beyond theming. It changes the geometry, spacing, and feel of the components so your app starts from a different visual baseline.
+
+Available now in [shadcn/create](/create) for both Radix and Base UI.
