 > **New — [CinematicBench](https://mustbesimo.github.io/cinematic-scroll-skill/bench/).** A reproducible, passive benchmark of scroll craft: 61 well-known sites scored 0–100 on Pacing / Performance / Accessibility / Motion Craft by a deterministic rubric ([methodology](./tools/bench/README.md)). Score your own site: `npx -p cinematic-scroll-skill cinematic-bench <url>` — same rubric family as the skill's [taste engine](./bench-mode.md).
 
-> **⬆ Upgrade — [Cinematic Scroll Studio](#) (paid).** This open-source skill **builds** cinematic, scroll-driven sites and **scores** them (the Taste Engine: doctor + hygiene gate). **Cinematic Scroll Studio** **learns your visual language and compounds it** — the full immersive **art-direction engine**: the complete **Motif Engine** (accumulated visual-language library + reuse telemetry + governed promotion + semantic dedup), motif-driven **storyboard / asset-direction / depth & motion** compilers, **variant generation**, and the full **web→video** pipeline. *Cinematic Scroll builds cinematic sites and scores them. Cinematic Scroll Studio learns your visual language and compounds it.* One-time purchase — download from the author's site.

 > **New in v2.4.0 — a machine-readable design system under the hood.** A DTCG **token contract** (`design.md` + `tokens/`), **visual systems** as one-file themes (swap one, or author your own), and a **9-component library** (Mode A `.html` + Mode B `.tsx`) make output deterministic and gated, not improvised — hardened by an adversarial self-review ([`REVIEW.md`](./REVIEW.md)). See **[Design system](#-design-system-one-token-contract--a-living-system--a-component-library)** below.
