CartChanges

one bordered notice above the cart that says each change in a plain sentence, with a way out for what sold out: one to three changes, the cart itself shown under it

a card per changed line, its picture, a tag for what changed and the old value struck beside the new one: changes the customer should look at one by one before paying

the changes sorted under « Prix », « Quantités » and « Épuisés », each a short ruled list: a long or trade cart where many lines moved at once
