Shader uniforms

The ferrofluid nucleus exposes these. Tweak insrc/shaders/ferrofluid.tsand the matching JS scene file.

uTime
float
Accumulating seconds. Drives breath + film drift.
uPointer
vec2
NDC -1..1, smoothed in JS each frame.
uPointerStrength
float
0..1 lerp; rises while pointer is over canvas.
uDisplacement
float
Master amount. 0 in reduced-motion.
uMobile
float
0 or 1. Skips heavy fresnel + halves displacement.
uBase
vec3
Obsidian base color (#0c0c10).
uSignal
vec3
Edge tint (#6E56FF).
uWarm
vec3
Inner-glow warm (#E8E4DC).
