Two design skills · both proven

banner-design vs tailwind-design-system

Brief: “Build the shop page for Verdant, an online plant shop: a header, a filter sidebar with categories, light and price, a responsive product grid with at least nine plants drawn in inline SVG, prices, ratings, add-to-cart buttons with a cart count that updates, and a footer. It should feel like a premium storefront.”
