The save-cart-btn event listener was placed after a return statement in
_attachEventListeners(), so it was never executed. Moved it to the correct
location inside the _cartCheckoutListenersAttached block alongside the
other cart/checkout buttons (reload-cart-btn, confirm-order-btn, etc.).
The _attachEventListeners() function was cloning the products-grid element
without its children (cloneNode(false)) to remove duplicate event listeners.
This destroyed all loaded products every time the function was called.
Solution: Use a flag (_delegationListenersAttached) to prevent adding
duplicate event listeners instead of cloning and replacing the grid node.
This fixes the issue where products would disappear ~1-2 seconds after
page load.
