Instrumented arrivals show the Hidden-state cloud's emitters spawn in the
arrival cell, become view-eligible when the world appears, and are never
drawn: the walk draws an owner's emitters only through the owner's registry
rows, and a hidden owner's shadow is suspended. Retail's
CPhysicsObj::add_particle_shadow_to_cell (0x00514a70) gives an emitter one
shadow in its own cell, drawn at that cell's turn regardless of the parent's
hidden state. S2 chunk 6 (packet §10) ports that: per-cell emitter draw
membership, owner-union particle path deleted. Route timing fixed so the
arrival screenshots anchor on the reveal.
