🍔 Quick Foods — Frontend Feature Overview

A clean, responsive, and real‑time shopping experience for multi‑store food ordering. This document focuses only on the frontend: UI/UX, interactions, and user flows across Customer, Store Admin, and Admin views (no backend tech).

🧭 Global UX & Design Principles

• Responsive Layout: Mobile‑first grid with breakpoint‑aware components; cards reflow (1 → 2 → 4 per row), sticky header on scroll.
• Consistent Navigation: Top navbar (logo, search, cart, auth), contextual breadcrumbs, tabbed sub‑navigation in store pages.
• Keyboard & A11y: Focus states, aria‑labels on icons, ESC to close modals, Enter to submit forms, live regions for toast messages.
• Visual Feedback: Loading spinners, disabled states, skeleton loaders for lists/images, optimistic UI where safe.
• Theme Tokens: Primary/secondary colors, status badges (success/info/warn/danger), elevation (shadow‑sm/md/lg), rounded‑xl.
• i18n‑Ready Copy: Text keys grouped by domain (navbar, cart, checkout, orders, admin); date/number formatting consistent.
• Client‑Side Validation: Inline error hints, password strength meter (Low/Middle/High), zip code auto‑complete via TWzipcode.

🏠 Customer Storefront

• Hero Carousel: Clickable banners (title + subtitle + CTA). Auto‑rotate with pause‑on‑hover.
• Store Gallery: Card grid; each card shows store image (fixed height 200px), name, tags, rating (optional), and “View Store” button.
