It separates the moment of commitment from the moment of collection: authorisation confirms that funds are available and places a hold, while capture moves the money. This flow applies only to card payments. It is initiated by setting `capture_method: manual` when creating a payment session. If omitted, `capture_method` defaults to `automatic`, which settles funds immediately upon authorisation (standard sale behaviour). When `capture_method: manual` is set on a session that goes through Moment Checkout, the checkout presents card payment methods only. Non-card options are not surfaced to the customer, so a manual-capture session always results in a card payment.
