-- POS payment capture
+- POS transaction summary lookup with open balance visibility
+- Transaction detail inspection for a selected transaction id
+- Recent payment activity review
+- Payment capture with retry-ready local session history
 - Protected route shell for summary, payment capture, and session inspection
