Meet the new Coach Model library — every motion certified before it earns the gold:

• Two brand-new coach cards: Slice and Return join Forehand, Backhand, Serve, Volley, and Overhead
• The volley coach now demonstrates a textbook punch volley from professional footage
• The serve coach reaches full stretch at contact — trophy, extension, snap, exactly as it should be taught
• Left-handed players get a complete coach library of their own, mirrored from certified swings
• Every coach motion passes a measured quality gate — clean tracking, verified contact — before it can appear on screen
• Replay loops now start muted, with a speaker button when you want the sound
