- Ball sizes now vary organically: smooth spatial value noise drifts size
clusters across the word, white noise roughens per ball; the neighbor cap
keeps every draw collision-safe
- Radial halo billboard tracks the cursor BEHIND the text plane, so balls
silhouette against the glow (additive in dark, soft accent wash in light)
- Cursor point light switched to physical inverse-square falloff (decay 2):
balls near the cursor are genuinely brighter; the light dims to 30% when
the pointer leaves so the resting state stays moody
- Dark mode is an eclipse rig: near-black lacquer balls (clearcoat physical
material), almost no front light, cool key + counter rim from behind, and
no environment map — scene.environment floods instanced materials at full
strength regardless of envMapIntensity, which was washing the whole word
to gray; light mode keeps the procedural room reflections
