A reusable, InstancedMesh-backed atmospheric particle emitter (falling ash, dust, rain, snow --
see WeatherEmitterOptions) for a box-shaped volume.
Every particle is a fixed slot in parallel Float32Array fields (no per-particle objects, no
per-frame allocation in update()), matching the instanced-pool pattern.
