   CRITICAL LAYOUT FIX

   (urgency) and woocommerce_after_add_to_cart_button (trust row + delivery)
   render INSIDE .woocommerce-variation-add-to-cart, next to the quantity and
   the button. The prototype assumed those were separate siblings and styled
   the container as one stretched flex row — which balloons the quantity box
   and the Add-to-Cart button to the height of the trust block and overflows
   the column. Lay them out as stacked full-width rows instead, with only the
   quantity + button sharing a line at their natural height.
