CartServe: Cart Drawer Upsells

Your cart is where buyers decide. CartServe turns Shopify's cart into a slide-out drawer you fully control - no code, no theme surgery. Drag and drop a dozen blocks, then preview live on real products and any market before publishing. Add reward goals (free shipping, spend tiers), a progress bar, in-drawer discount codes and opt-in shipping protection. It installs on your existing cart button and fails safe: if the drawer can't load, your theme's cart takes over. Checkout is never blocked.
