  "description": "Foundation for declarative motion: an Animation COMP showcase with two channels (tx, ty) wrapped by a Null CHOP for stable downstream binding, plus a Constant TOP target whose color (r, g) can be driven by the channels via expressions. The Animation COMP is created empty here — the artist opens it and authors 5 keyframes per channel in the Animation Editor (0s/1s/2s/3s/4s, eased), then sets target expressions like op('anim_null')['tx'] on out_color.colorr. Mirrors the conceptual shape of create_keyframe_animation (Layer-1, v0.7.0) using declarative TD nodes instead of a runtime Execute DAT. Offline-validated against RecipeSchema; live cook-check UNVERIFIED pending TD run. Manual-wire: (1) author tx/ty channels inside anim's Animation Editor; (2) set out_color.colorr expr to op('anim_null')['tx'] and colorg to op('anim_null')['ty']. For true playback-rate control, set animationCOMP's play mode to Sequential and drive its `speed` parameter directly (Speed CHOP does not retime an animationCOMP — it integrates input channels).",
