# util Small shared helpers for the other juiceKit modules. Vectors as `{x,y,z}` maps (`vec` accepts arrays, maps and vectors), quaternions as `{x,y,z,w}` maps (`q` accepts arrays too), a seeded `rng`, `clamp` and `lerp`, and target resolution: `entityOf`, `positionOf`, `localAvatar`, `cameraEntity` and `cameraPos`. Also `rgba` for UI colours and `isPlaying`.

# JuiceShakeApply Attached to the scene camera by `juiceKit.shake`; you never add it yourself. It runs late (execution order 10000), after every camera controller, and adds the current shake offset to the camera's pose, remembering exactly what it added.

# shake Additive camera shake. `play(spec, opts)` starts a layer: noise, a directional kick (pushed away from `opts.from`, or along `opts.direction`), a rumble or a quake, optionally with distance `falloff = {near, far}` measured from the listener. It returns the strength after falloff, or 0. Layers are capped (`MAX_LAYERS`, `MAX_AMP`, `MAX_ROT`). `attach()` puts JuiceShakeApply and JuiceShakeRestore on the scene camera, and `play` calls it for you. The offset is applied after the camera controller and removed before the next one, so the camera never drifts. Also `falloff`, `listenerPosition`, `offset`, `activeCount`, `stop` and `stats`.
