// `light_access.wgsl` stays: it defines the `LightsInfoPacked` / `LightPacked`
// structs that `bind_groups.wgsl` declares the group(1) light bindings with
// (binding ABI — always present). `apply_lighting.wgsl` is deliberately NOT
// included: this kernel only writes the skybox and never calls any lighting
// orchestration, so pulling the punctual walk (which references `brdf_*`)
// would be dead code.
