What is the purpose of deploying spoilers after touchdown?

Explanation:
Spoilers deployed after touchdown spoil lift on the wings. By reducing lift, more of the airplane’s weight stays on the wheels, which makes the wheel brakes and thrust-reverse or ground handling more effective and helps slow the aircraft quickly and controllably during rollout. Spoilers also help stabilize the airplane on the runway as it decelerates. This isn’t about climbing, retracting gear, or extending flaps after landing—those actions serve different phases or functions. The primary purpose here is to aid deceleration.
