Two forms: ShadowDusk.Compiler (NuGet, in-memory EffectCompiler.CompileAsync(hlslSource, options) — use this for build-time embedding of engine-shipped shaders) and ShadowDuskCLI (drop-in mgfxc replacement for existing content-pipeline builds).
Gotcha: Metal (macOS/iOS) isn't implemented yet — Metal targets still need the traditional Windows/Wine path (see shaders skill). Output is behaviorally equivalent to mgfxc, not byte-identical — don't diff bytecode across compilers in a test.
