{#
    Names the group discount on the checkout page, which core renders as a bare
    total with no breakdown and no template hook.

    This is not a fork.  Indico's customization loader resolves a leading `~`
    to the *original* template, so this file inherits everything core does and
    only prepends a box.  If core rewrites the page, we inherit the rewrite.

        {#
            The group was repriced upward after this member paid.  Core's
            checkout charges `registration.price` in full -- it has no notion of
            a partial payment -- so letting them through here would take the
            whole new price again on top of what they already handed over.  The
            balance is collected off-platform and recorded by an organizer; see
            the "Balances due" page in the management area.
