Struct DifficultyProfile 

pub struct DifficultyProfile {
    pub level: u8,
    pub name: String,
    pub reaction_delay_ms: f32,
    pub prediction_accuracy: f32,
    pub max_paddle_speed: f32,
    pub error_magnitude: f32,
    pub aggression: f32,
}

A single difficulty profile defining AI behavior.

Difficulty curve formula (from design spec):

• reaction = 500 * (1-t)² + 50 where t = level/9
• accuracy = 0.30 + 0.65 * t
• speed = 200 + 400 * t
• error = 50 * (1-t)² + 5

Fields

level: u8

Difficulty level (0-9)

name: String

Human-readable name for this level

reaction_delay_ms: f32

Base reaction delay in milliseconds

prediction_accuracy: f32

Ball position prediction accuracy (0.0-1.0)

max_paddle_speed: f32

Maximum paddle movement speed (pixels/second)

error_magnitude: f32

Random error magnitude in target position (pixels)

aggression: f32

Aggression factor - how much to anticipate vs react (0.0-1.0)
