Build a product page for {{business_name}}'s online store, selling to {{target_audience}}. Product details, variants and price: {{product_details}} Layout: gallery beside the buying panel on desktop, stacked above it on phones. Brand colors: {{brand_colors}}. Requirements: - A gallery with thumbnails, swipe, zoom and alt text for every photo - Size or color options as labeled choices, so color is never the only cue; sold-out options stay visible but disabled, and price, photo and stock update with each choice - Add to cart opens a small cart drawer with a clear checkout button, and the cart survives a refresh - Next to the button: price, delivery estimate, returns in one line, and a size or usage guide if relevant - Description, benefit bullets and specs written only from the details above; mark anything I need to confirm - Reviews shown only when real ones exist; never invent them - A sticky add-to-cart bar on phones - Checkout created on the server with prices from the server, never from the browser; payment keys stay server-side - WCAG 2.2 AA, fast images in modern formats, and a title, meta description, share image and Product structured data with price and availability When you're done, list your assumptions and what's needed to take real orders.
