Quick View Modal for Products

Create a quick-view modal system for my store. When a customer clicks a Quick View button on any product card in a collection or grid, a modal overlay should appear showing: a product image gallery (with thumbnail navigation), product title, price, variant selectors (size, color, etc.), quantity selector, Add to Cart button, and a View Full Details link to the product page. The modal should load product data dynamically via the Shopify Product AJAX API (/products/[handle].js). Include a close button and allow closing by clicking outside the modal or pressing Escape. The modal should be accessible with focus trapping. Style it with a [MODAL_STYLE] look (options: minimal, rounded, full-screen on mobile). Generate the Liquid snippet, JavaScript, and CSS needed.
