A separable diffusion profile shared by opaque or alpha-masked PBR surfaces.
Radius is the standard deviation of each channel's bounded Gaussian diffusion kernel, in the
same units as mesh positions and camera distance. Equal radius triples are the same profile;
profile identity never depends on a process-global counter. Thickness limits each radius.
