  "description": "Reproducible twin of create_layer_mixer in crossfade mode: two sources blended by a single Cross TOP with a 0..1 crossfade knob (0 = source A, 1 = source B). Self-contained sources (a noiseTOP and a rampTOP) so it previews offline; swap them for selectTOPs pointing at your real layers. Unlike decks_layer_mixer (additive two-gain blend), this is a true A/B crossfade on one control. Offline-validated against RecipeSchema; UNVERIFIED pending live cook-check.",
