## Overview

This is a client-side coffee-shop POS admin dashboard. Staff navigate its sections to manage a menu, build carts and orders, record simulated cash/card checkout, and review operational summaries. The page owns the live order, cart, menu, inventory, promotion, and payment-history state; the supplied source shows no backend or persistent database. README capabilities also include employee management and scheduling, though their implementation was not sampled. Edges reflect the visible page-to-component wiring; unsampled section internals are represented without speculative call links.

Main entry points: [`app/page.tsx`](https://github.com/gobi1990/coffeeshop_pos_system/blob/main/app/page.tsx) (POS page state), [`app/interfaces/interfaces.tsx`](https://github.com/gobi1990/coffeeshop_pos_system/blob/main/app/interfaces/interfaces.tsx) (Domain types), [`app/components/sections/menuSection.tsx`](https://github.com/gobi1990/coffeeshop_pos_system/blob/main/app/components/sections/menuSection.tsx) (Menu browsing), [`app/components/ui/cartSidebar.tsx`](https://github.com/gobi1990/coffeeshop_pos_system/blob/main/app/components/ui/cartSidebar.tsx) (Cart sidebar)
