Cube-array view (dimension 'cube-array') of every probe's irradiance cube.
Cube-array view of every probe's prefiltered specular cube.
Uniform buffer matching ProbesUniform in deferred_lighting.wgsl.
OptionalshPer-probe SH diffuse coefficients (array<ShCoeffs, MAX_PROBES>). Bound at
binding 8 in the IBL_DIFFUSE_SH variant; ignored otherwise.
GPU resources the lighting pass needs to bind for reflection-probe sampling. ReflectionProbeFeature builds this and routes it through the DeferredLightingFeature into
DeferredLightingDeps.probes.
