`AnimatedRadialCosine` is splat-local rather than field-world anchored. It
evaluates
`cos(pow(distance01, FrequencyY) * FrequencyX + PhaseX + simulationTimeSeconds * AnimationSpeed)`.
`FrequencyX` is radial frequency and `FrequencyY` is the positive radial
exponent. The ordinary splat falloff owns the envelope, which keeps oscillation
and compact support independently composable.
