When the account manager checks out with a member selected:

• An info banner at the top reads Cart is for account member: Name LastName.
• If the manager pays for that member, the payment step shows a warning You are paying for your member Name LastName, and the manager's own saved cards are listed.
• Delivery address and pickup options are those of the member's account; if the member has an assigned pickup point restriction, only those pickup points are listed.

When the member checks out while the manager pays, the payment step shows This is being paid by your account manager and the card (Stripe) option is hidden; the manager's card on file is charged.
