Two problems in the previous back-in-stock commit: the disabled "Ausverkauft" button and NotifyMeForm stacked, making out-of-stock cards visibly taller than in-stock siblings — and since ProductGrid's cards rely on plain CSS Grid row-stretch for equal card height, that extra height stretched sibling cards and pushed their own buttons down (screenshot: "In den Warenkorb" CTAs misaligned across a row). NotifyMeForm now replaces the button slot entirely when out of stock (matching the height of a normal button when collapsed), and only expands to the email input after a click.
