The browser put the CNPJ, WhatsApp, e-mail, CEP and address back after a
reload without telling the page, which then showed them but could not pay
until they were typed again. The fields are now emptied on load and marked
autocomplete="off", and the saved cart holds only the items: the details and
address are typed again after a reload or a closed tab. The payment page
already takes them from the server.
