        Grant {recipient} an ordinary free force revival rate of three this phase. This
        replaces their native ordinary rate rather than adding three. Ordinary total
        revival and special-force limits still apply.

        Provisional current-rate policy: Recruits doubles the current granted rate, including applicable bonuses,
        before caps. Without other bonuses, three becomes six.
        Later grants use the same current-rate calculation;
        your ally’s revival controls show the actual remaining allowance.
        Previously recorded free returns use the allowance. Earlier paid returns keep their payments and count
        toward the total revival limit; there is no refund or retroactive
        reclassification.

      <p className="fine">
        Another player may use Karama before the original alliance grant takes effect.
        Canceling blocks this Fremen grant to the current ally for this Revival;
        the ally retains its intrinsic rate and Recruits. Completed revivals and
        payments stay unchanged. This response timing and prevention scope are provisional.
