            The ring is the club's own primary colour, same as on the club's own subdomain --
            but the control panel never injects a page-wide --color-primary override (it must
            not dress itself up as the club), so it's set here as a locally-scoped custom
            property instead: it only reaches this element and its children, not the rest of
            the panel's buttons and badges.

        The club's own numbers that should be zero. Teams without a manager is a defect in
        the club's setup, not a statistic: with nobody in a management position the access
        service grants no authority over that team, so nobody can pick the squad.
