Function: generateRingVariation()

function generateRingVariation(config, rng): RingVariation | null;

Generates a ring variation from the shared planet PRNG. Draws the same number of random values regardless of hasRings, so enabling/disabling the flag never drifts the rest of the planet appearance.

Parameters

Parameter	Type	Description
config	BodyConfig	Planet physics config (drives palette + rejects star bodies).
rng	() => number	Planet-scoped PRNG (same instance as planetVariation).

Returns

RingVariation | null

• A fully-populated RingVariation, or null when rings are disabled.
