Your PAWTURE designer dog clothing e-commerce site is complete. Here's what was built:

• Homepage with a full-screen hero image, featured products grid, three curated collections (Winter Warmth, Black Tie Bark, Trail Ready), brand values section, customer testimonials, and a newsletter signup.
• Shop page with a sidebar filter system for categories (Sweaters, Coats, Jackets, etc.) and collections, displaying 8 unique products with real generated images.
• Product detail pages with size/color selection, a personalization input for monograms and custom text on customizable items, quantity controls, and an "Add to Bag" button with confirmation feedback.
• Cart drawer that slides in from the right, showing items with quantity adjustment, removal, subtotal, and a checkout button -- all powered by React Context for state management across pages.

To access Design Mode in v0, look at the left sidebar of your chat interface. You'll see a few icons/options — click on "Design" at the top of the sidebar. This opens Design Mode, which lets you visually edit styling properties like colors, spacing, typography, and layout directly on your app's preview without writing code.

Once in Design Mode, you can click on any element in the preview to select it and adjust its styles using the UI controls that appear. Changes are applied in real-time so you can see the results instantly.
