heatShimmer
The air over a fire, as a lens. A blend-queue shell wearing this material reads the lit opaque scene behind it through `zero::scene_color` at a displaced coordinate, so the shelving standing behind the shell is what wobbles — the shell itself is never seen.

Nine shells stand at nine heights up the shaft and each is hot at a different moment, so how hard each one bends the picture rides its own per-instance lane rather than the shared material:
| lane | contents |
|---|---|
| 3 | x displacement in screen fractions, y glow, z rise in metres a second, w coverage |
The material carries cell, the size of one turning cell in world units, and
glow_color, the emission of the hottest air near the source.
