# Note: "off-session" processing happens when a payment is placed on behalf of a user when
# they are currently offline. This can happen with backoffice orders or subscriptions.
# In that case; if the payment requires authorization in Stripe, we send an email so the user
# can authorize it later (asynchronously).
