The Noise namespace (GS_Core::Noise) provides a project-owned, stateless, deterministic, thread-safe Perlin noise toolkit. It backs every continuous-noise subsystem in the framework — PhantomCam Noise Profiles and the PerlinNoise / ImpulseNoise additive stages — plus any future UI wobble, unit idle-jitter, or VFX parameter modulation consumer that needs smooth time-varying values.

The same NoiseLayer struct documented below is what CameraNoiseProfile stores in its six per-axis vectors — no duplication. The utility is intentionally outside PhantomCam so non-camera consumers can adopt it without pulling a camera dependency.

The OrbitalSolver namespace (GS_Core::Math) provides a stateless, deterministic, pure position / pose blend primitive. Given two positions (or transforms) and a pivot point, it blends them by a fraction t along an arc that preserves the geometric relationship to the pivot — rather than the straight-line lerp that cuts through the pivot when the start and end sit on opposite sides.

The primitive originated as a fix for PhantomCam cross-cam blends (two orbit cams at ~180° around a shared target produced visible “cuts through the target” mid-blend). It has since been reframed as the standard movement primitive for any motion naturally arranged around a pivot — orbit cams, leading-follow band response, post-config stage transitions. Linear lerp becomes the special case used only when no meaningful pivot exists.
