Henrik RydgårdandClaude Opus 5.5 961726dc88 VFPU: vrnds takes its seed from the vs field ...

The toolchain encodes vrnds's operand in vs and leaves vd zero, so we
always seeded from S000. Resistance: Retribution reseeds per particle
from S620, which made every particle in its smoke and explosions take
new random values each frame. They flickered, and some never drew.

Hardware test: cpu/vfpu/vrnd (vs and vd fields).
