• Layout & Navigation: Sticky navbar with centered "GOOWALK" logo, nav links (Men, Women, Kids, New Arrivals, Sale), expandable search bar, user profile icon, and cart icon with a red badge count. A dismissable announcement bar sits at the top promoting free shipping.
• Home Page: Full-width hero slider with auto-advance, a 3-card category grid (Men's, Women's, Accessories) with hover-zoom effects, and an 8-product "Best Sellers" grid with image-swap on hover and Sale/New badges.
• Product Detail Page (/product/[id]): 2-column layout with thumbnail gallery, EU size selector, quantity picker, sticky "Add to Cart" button, and expandable Product Description and Size Chart sections.
• Shop Page (/shop): Filterable product listing with a desktop sidebar and mobile drawer for Brand, Size, Color, and Price Range multi-select filters. URL query params support category and badge pre-filtering.
• Cart Drawer: Slide-out side panel showing cart items with quantity controls, subtotal, and checkout button. A mobile bottom navigation bar provides native-app-like tab navigation on smaller screens.
