Optional skill: scroll-as-timeline landing pages on a deterministic CSS/JS engine, with interview → page grammar → signature move workflow and screenshot-based scroll verification. Engine and scripts vendored verbatim; asset generation re-anchored on image_generate with the upstream kie.ai flow kept as an optional path.
