 * Palette: "Automotive/Car Dealership" from the ui-ux-pro-max design-system

 * the source palette reuses red for both the primary accent and destructive
 * actions, which would collide with this app's existing "red = delete"
 * convention. Navy is used as the primary action color instead; red is
 * reserved strictly for destructive/danger.
