Epic 5 Phase 2.5 — model blend via alpha, not lumakey

Browse Source 
Model stages render with alpha:0 where no mesh covers (transparent
clear) and carry dark material colours. Lumakey keys on luma
(dot(src,0.212…)), so a dim mesh keyed to ~0 and vanished — Pylon
Field 3D / Synthwave Corridor looked black. Use 'normal' for
kind:'model' so the alpha is the mask; fragment over dark ground
stays covered. Per-stage fog/light tuning deferred to a director
param (LookGenerator) per review — not hand-tuned per stage.
