Pattern A — Quick view only. Hover a product → a single Quick view button slides up. There is no add-to-cart on the card itself; you add from inside the mini-PDP modal. Closest to Anthropologie. One more click for shoppers who already knew what they wanted.
Pattern B — Both. Hover a product → Add to cart (one-tap, instant) and a Quick view button slide up. Impulse buyers add in a single click; considerers open the mini-PDP to see the carousel + details first. Hover any card and try both.
