Interior rooms light per fragment from their authored fixtures instead of
the MOCV bake (direct + fill + ambient, soft rolloff; live cvars
interiorLight/interiorAmbient/interiorFill/interiorExposure/interiorShadows/
interiorDebug), TRANS/EXT batches blend to the day/night reference at the
portal seam, and fixtures admit camera-independently (90 yd).
Torch shadows are a from-scratch depth-map renderer (Bevy point shadows are
dead under ClusterConfig::None): a shared Depth32Float 512^2 x 24-layer Image
+ depth-only pipeline + ViewNode rendering the static caster and a per-frame
entity caster into 6 cube faces for the nearest <=4 fixtures (reverse-Z,
GreaterEqual compare, 4-tap PCF, far fade). WMO surfaces receive through
static_gx group 3; entities receive on the wow_model path through
WowModelExt bindings 91/92/93 (depth array, comparison sampler, 1616-byte
torch table) with a 0.15 yd normal offset against CPU-vs-GPU skinning
self-shadow.
The entity lane is gated on is_interior OR the new MATTE_INDOOR tag bit
(exterior payload bit 14, written by the classifier's Matte law), so a unit
whose verdict flickers Bake<->Matte at one spot keeps its room lighting.
