Kiro adds credit pooling: $20 seats feed one shared 500-credit-per-seat team pool
Enterprise admins can now pool credits across seats (minimum two, billed through AWS), set per-user, group and profile limits, and buy add-on credits at $0.04 each that last 12 months. It's the only option for new Kiro profiles, and existing customers who switch can't undo it (changelog).
