Module camera 

Proof Engine camera system.

Provides three camera modes usable independently or together:

1. Free camera — spring-driven position + target with trauma shake
2. Orbital camera — rotates around a target at a given distance, with zoom
3. Cinematic path — follows a spline path of control points at a given speed

All three use SpringDamper physics for smooth, organic motion. Shake/trauma is applied as an additive offset after spring resolution.

Structs

CameraState

A snapshot of camera state for this frame.

CinematicPath

A cinematic camera path — plays through a sequence of PathPoints.

OrbitalCamera

Orbital camera — rotates around a target point at a configurable distance.

PathPoint

A control point on the cinematic camera path.

ProofCamera

The main engine camera. Supports free, orbital, and cinematic modes.

TraumaShake

Camera trauma/shake state, driven by a decaying trauma value.

Enums

PathEasing

Easing function for a path segment.
