Add 3-Second Visual Countdown Before Ball Launch After Each Point

Currently, after a player scores a point, the ball launches immediately, leaving no time for the player(s) to prepare for the next rally.
This can be jarring, especially at higher ball speeds.
I propose adding a 3-second visual countdown before the ball launches after each point.
The countdown will display prominently in the center of the screen (e.g., “3”, “2”, “1”, “Go!”) and will pause all gameplay until it completes.
This feature will:
Give players a short moment to prepare.
Add polish and professionalism to the game.
Make gameplay feel fairer and more beginner-friendly.
