Checkout email field not editable on mobile/desktop

User reports that the email input field on the hosted checkout page (https://www.creem.io/payment/prod_2vrxndDZOkFNP7jZyEUJip) cannot be typed into manually on mobile (Safari/Chrome) or desktop. Only autofill works on mobile, and manual input is blocked on desktop. Store ID: sto_rUI0XJoV6fg2fEMZAHfKT. This is preventing customers from completing payments.
