Type Alias Angle 

pub type Angle = u16;

An angle in the range [0, 65535], representing a full rotation [0, 2π).

The mapping is:

• 0 → 0 radians
• 16384 → π/2
• 32768 → π
• 49152 → 3π/2
• 65535 → ~2π

This representation allows fast angle arithmetic using only bit shifts and avoids floating-point operations entirely.
