1//! The shader `Platform` vocabulary: which compiled shader form a rendering
2//! backend consumes. The enum is pure data with no ambient resolution of its
3//! own, so it sits in the runtime foundation and every caller states the
4//! platform it means -- the engine names the backend it was built for, and the
5//! build pipeline is told the backend it cooks for.

7/// The shader targets the engine compiles for. Each variant matches one render
8/// backend: Metal (MSL), DirectX (DXIL), or Vulkan (SPIR-V).
