+                - Added 'focus:ring-ring' to ensure keyboard users see where they are typing.
+                - 'text-muted-foreground' used for placeholder text to distinguish from user input.
+                - Border color 'border-border' ensures the UI elements remain visible against the dark background.
+                - Component is fully encapsulated in a card for better visual separation.
