    """#091 Leraje idx=0 — Field Passive: Counter-Attack.

    If Leraje is Readied when Any Other Demon deals >= 1 damage to Any Demon,
    Leraje may perform an Attack targeting the damaged Demon at -1 AP Cost,
    ignoring (exhaust) costs. Range is NOT ignored (Leraje has Distant range).

    Fires on DAMAGE_RECEIVED.
    Checks: Leraje READIED, source != Leraje, value >= 1, target in Distant range.

    Leraje's range is Distant (different lane). The counter-attack is a basic
    Attack: deal Leraje's effective PWR as damage (DEF applies) to the target.
    AP cost: max(0, ATTACK_AP_COST - 1) = 1 AP deducted from Leraje's owner.
    Leraje does NOT exhaust (exhaust cost ignored per card text).
