Struct ShadowPassPush 

#[repr(C)]
pub struct ShadowPassPush {
    pub cascade_idx: u32,
    pub _pad: [u32; 3],
}

Per-shadow-pass push constant identifying which cascade is being rendered. Used so the shadow vertex shader can index ShadowUniforms.light_vps[i] from a single bound UBO instead of re-binding a different uniform per pass.

Consumed at runtime only by the Metal shadow pass (Vulkan and DirectX each define their own private push-constant layouts in their respective draw.rs modules), but kept un-gated like the rest of this module so the shared shader-layout contract can validate its MSL layout on every platform.

Fields

cascade_idx: u32

Which cascade the shadow pass is rendering.

_pad: [u32; 3]

Padding so the field layout matches the shader-side struct.
