A smoke plume: a column of puffs that swell and drift as they rise, for the
rim of a volcano (see applyVolcanoes and its volcanoSmokeLayer).
Vertex-coloured from a darker base to a paler crown so a single flat
material shades it, and merged into one geometry so it instances like any
other scatter. It is a static shape — the drift is baked into the offsets,
and WindSway bends the top of it with the trees.
