Subject: [PATCH] MONKEY: dynamic WMO interiors + cube-map torch shadows
 (surfaces + entities)

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.

-//! SPIKE SCOPE: env-gated (`WOW_TORCH_SHADOWS`), ONE torch, reuses the world lane's layer-31 casters
-//! — so `worldShadows` must be on for the walls/columns to exist as casters. Milestone: a column
-//! throws a shadow on the interior floor that tracks as you move. Not yet a cvar/slider feature.
+//! Gated on `interiorLight` + `interiorShadows` ([`VideoConfig`]); declares demand so the shared rig
+//! stays up. Remove this module + its plugin + the `interiorShadows` cvar and the other lanes are
+//! untouched. (Phase 1 receiver = static_gx WMO surfaces only; wow_model/entities/terrain are later.)

+//! MONKEY (torch shadows, Phase 1): a from-scratch depth-map render for the nearest interior torch
+//! fixtures.
+//!
+//! benilla's world camera sets `ClusterConfig::None`, which disables Bevy's point/spot clustering AND
+//! starves the point-light shadow-map prep — so Bevy's built-in `fetch_point_shadow` path is dead for
+//! us (see `benilla_app::torch_shadow`). This module replaces it: for each of the nearest ≤4 interior
+//! fixtures (published by the app as [`TorchShadowViews`]) it renders the retained interior caster
+//! geometry from the fixture's viewpoint into one layer of a `Depth32Float` 2D-array texture.
+//! `static_gx.wgsl`'s interior surface lane then samples that array (group 3, built in `render.rs`)
+//! so a pillar throws a radial shadow on the floor.
+//!
+//! **Phase 3A: the depth array is a shared `Image` ASSET**, not a render-world-owned texture. The
+//! entity receiver (`wow_model.wgsl`, every unit/NPC/GameObject/interior prop) has no spare bind
+//! group — a Bevy material draw sets groups 0/1/2 only — so its torch bindings ride the material's
+//! own group as `Handle<Image>` + raw `Buffer` fields (`WowModelExt::torch_depth`/`torch_buf`),
+//! and `AsBindGroup` resolves a `Handle<Image>` through `RenderAssets<GpuImage>`. So the image
+//! ([`TorchDepthImage`]) is created ONCE at app startup in the main world (always — an absent image
+//! would stall every model material's bind group and blank every model), extracted here, and BOTH
+//! receivers read the same `GpuImage`: the depth node renders into per-layer views of its texture,
+//! static_gx binds its D2Array view, the material binds the same view + the image's comparison
+//! sampler. The ≤4-fixture table gets the same treatment ([`SharedTorchBuffer`]: one raw buffer,
+//! rewritten in place every frame from [`TorchShadowViews`] with the SAME [`TorchTableUniform`]
+//! bytes static_gx's group-3 uniform carries).
+//!
+//! Reverse-Z throughout (the whole engine is — `capture::depth_probe`): the depth pass clears to 0.0
+//! (= far), keeps the nearest surface with `GreaterEqual`, and the comparison sampler is `GreaterEqual`
+//! too. The per-fixture `view_proj` is a reverse-Z perspective built app-side in f64 (fixtures sit at
+//! absolute Bevy world coordinates, ~9,300 out) and downcast to f32.
