 ## Released Versions
 
+## [1.4.0] - 2026-09-14
+
+### website
+- Added a **More from ReScience Lab** section to the opc.dev homepage, above the skills grid, featuring the [super-prototyping](https://github.com/ReScienceLab/super-prototyping) plugin: banner, description, keyword tags, and links to the repo and prototyping.rescience.com
+- Added `super-prototyping` to the footer links
+- Added blog post: *Clone Any App Screen — and Prove It: Introducing super-prototyping*, covering the clone-prototype phases, the canvas, the fourteen worked examples, and the per-agent install
+- **Fix**: skill cards rendered 907px wide inside their 852px grid container, so every card sat wider than the header and hero and the page scrolled horizontally. The skills grid had a single implicit `auto` column, which sizes to max-content; pinned to `minmax(0, 1fr)`
+- **Fix**: blog post dates are formatted in UTC. `new Date("YYYY-MM-DD")` parses as UTC midnight, so a negative-offset zone rendered the previous day and a post's card and byline could disagree
+
+No skill versions changed in this release.

+# Clone Any App Screen — and Prove It: Introducing super-prototyping
+
+*By OPC Team | September 14, 2026 | 8 min read*
+
+**TL;DR** — We shipped [**super-prototyping**](https://github.com/ReScienceLab/super-prototyping), an agent plugin that rebuilds product UI as self-contained HTML artboards on a local [tldraw](https://tldraw.dev) canvas. Hand your agent screenshots, ask for the `clone-prototype` skill, and it grids the capture, samples it region by region, writes one measured token block, generates every board from a single `gen.py`, then re-renders and diffs those boards against the capture until the numbers hold. Every colour and every metric traces back to a measurement. It is Apache-2.0, works in Claude Code, Codex, CodeBuddy, Hermes, Pi and anything that reads `SKILL.md`, and it is now featured on [opc.dev](https://opc.dev).
+
+---
+
+## The Problem: "Looks About Right" Is Not a Replica
+
+Ask any AI agent to rebuild a screen from a screenshot and you get something that is *approximately* the app. The blue is a blue. The row height is a row height. The font is "a clean sans-serif."
+
+Individually each value is off by two or three points. Together they read as a knock-off, and nobody can tell you **which** value is wrong, because no value was ever measured. It was inferred from a thumbnail the model glanced at.
+
+That is the failure mode super-prototyping is built against. The rule the whole plugin is organised around:
+
+> **Every colour and every metric in a cloned artboard traces to a measurement.**
+
+Grid the reference image. Look at it. Name the element. *Then* write the token. No evidence, no token.
+
+---
+
+## What is super-prototyping?
+
+It is an **agent plugin**: three skills, a measuring toolkit, and a local canvas app that shows the boards.
+
+| Skill | Use it for |
+|---|---|
+| **clone-prototype** | Copying a real app's screens from captures, by measurement |
+| **new-ui-mock** | Designing new screens with no reference, built on existing tokens — including the empty, loading and error states |
+| **prototype-canvas** | Running and operating the canvas: boards, `layout.json`, deep links, annotated-screenshot review |
+
+The output is plain files. Each board is one `.html` file in `mockups/canvases/<board>/`, fully self-contained — no external CSS, JS, fonts or images, `data:` URIs and inline SVG only, because boards render inside `<iframe srcDoc sandbox="">`. The canvas picks them up as shapes with **no registry, no build step and no design tool**.
+
+Your project holds boards and nothing else. The plugin upgrades around them.
+
+---
+
+## How a Clone Actually Runs
+
+`clone-prototype` is phased, and the phases do not reorder. Sampling before tokens, tokens before HTML.
+
+### Phase 0 — Collect references, and one number
+
+Every capture is saved to a scratch directory *first*, because image caches rotate mid-task. Then the capture scale gets recorded once, in pixels per design point, and cross-checked against height:
+
+```
+300 / 393 = 0.7634 px/pt
+```
+
+That number decides what is measurable. A 0.76 px/pt strip cannot settle a 1pt divider, so the skill goes and gets one native @3x capture of *any* screen in the same app before it trusts thin ink.
+
+### Phase 1a — Grid, then look
+
+```bash
+refkit grid p4.png -o g04.png --zoom 3 --minor 10 --major 50
+```
+
+This draws a labelled grid onto the pixels — cyan every 10pt, red every 50. The agent then reads that image **as an image** and names the element each region belongs to *before* measuring anything.
+
+This ordering is the point. Coordinates picked blind produce numbers with no element attached, and those are exactly the numbers that land in the wrong token.
+
+### Phase 1b — Sample, region by region
+
+```bash
+refkit sample p4.png 76 646 132 668 --pt 3
+```
+
+A census over **one named region**. Which line of the census you believe depends on what you pointed at:
+
+- **page, card, sheet** → flat fills. A pixel equal to all four neighbours is a real fill, not an antialiased edge
+- **badge, dot, brand mark** → all pixels, top entry, on a core-only crop — too small to have a flat interior
+- **text** → the ink core, the darkest few percent. The *mode* of a text region is its background, not its ink
+- **pitch, edges, radii** → `bands` / `bbox` / `scan`
+- **1pt divider or border** → `refkit hairline`, which solves from the ink deficit, because a hairline never reaches full coverage in a downscaled capture
+
+Out of this comes a token table with an **evidence** column.
+
+### Phase 1c — Name the face
+
+```bash
+refkit font ref.png 17.3 139 78.7 152 Libraries --pt 3 --fonts brand/
+```
+
+It renders that one word in every candidate face and ranks the glyph shapes at a common cap height. A closed set of ~20 faces on disk is the right problem to solve: published classifiers answer a 3,000-class Google-Fonts question and so structurally cannot name *SF Pro*. Under a 0.05 top-two margin it reports **no call** rather than naming a lookalike.
+
+### Phase 2 — One design system
+
+One `:root` block: the measured font stack, the colour ramp, radii per component class, composite `font:` shorthands, geometry constants. It is built as the **first** artboard, because it is the contract every later screen is checked against.
+
+### Phase 3 — One generator
+
+A single `gen.py` emits every screen, inlining that `:root` byte-identically.
+
+**Artboards are output, never source.** Hand-edit one and the next run reverts it.
+
+Artwork already present in the capture is *cropped out of the capture* at its own measured box, keyed by id in a `crops.json` the generator reads — so an asset cannot drift from where it was measured, and a box correction is one edit rather than two. A crop is the reference's own pixels, so it scores **Δ 0** by construction. Only what no capture contains gets generated.
+
+### Phase 4 — Verify by rendering
+
+```bash
+shoot --crop-phone --check-overflow
+diff --regions
+tokens
+```
+
+Render, de-frame, put your fill next to the reference's, audit the `:root`. The output is a **Δ per region, in numbers**.
+
+The loop is 1a → 4 → 1a. A `diff` that disagrees sends you back to the grid, not to the CSS. A correction you have not re-rendered is not a correction.
+
+### Phase 5 — Park the reference
+
+Each source capture becomes its own `ref-NN-*.html` board and is listed as a third `layout.json` row **in the same order** as the replicas. Rows lay out at `index × (w + gap)`, so item N lands under item N.
+
+The result: every replica sits directly above its source capture, cropped to the same 393 × 852 screen and masked to the same 52pt corner radius. The two are one glance apart rather than one memory apart.
+
+---
+
+## The Canvas
+
+```bash
+sp-canvas start
+```
+
+It finds the bundled canvas app, installs its dependencies on first run, boots on `127.0.0.1:5173` against `./mockups/canvases`, and prints the address. `sp-canvas status` and `sp-canvas stop` do what they say.
+
+![The super-prototyping canvas: an X iOS clone on the board grid, with 07-profile.html open in the inspector](https://raw.githubusercontent.com/ReScienceLab/opc-skills/main/website/blog/2026-09-14-super-prototyping-canvas.png)
+
+*An `x-ios` clone on the canvas. Boards sit on the grid at left; clicking one opens it in the inspector at right — live at its real 393 × 852 pt, with its layer tree, its assets, and the count of design tokens it actually uses (20 of 60). Nothing here is a picture of a screen: each board is the HTML, rendering.*
+
+Deep-link a page with `?canvas=<slug>`, and one board of it with `?canvas=<slug>#<file>` — it opens in the inspector with the camera on it, and clicking any board writes that link into the address bar. The URL in the bar is always the link to share. A board folder added after boot appears on its own.
+
+Every board is clipped to a 478 × 980 shape box. The iPhone frame is 393 × 852 pt at 1pt = 1px, with a 54px status bar, a 125 × 36 Dynamic Island and a 139 × 5 home indicator.
+
+---
+
+## Fourteen Worked Examples, Not a Demo Video
+
+The repo ships **fourteen app folders** in `mockups/canvases/`, each a real `clone-prototype` run with the evidence recorded for every token. Five are walked through in the README:
+
+- **`duolingo-ios`** — eight screens of the learning path plus two modal sheets, mostly picture
+- **`luma-ios`** — twelve screens, including the case where the replica draws a Dynamic Island the capture does not have
+- **`notion-ios`** — eighteen screens from @3x captures
+- **`claude-ios`** — fifteen screens across four flows
+- **`raycast-ios`** — eleven screens across three flows
+
+Copy any of them as a starting point: `sp-canvas root` prints wherever the plugin landed.
+
+---
+
+## Installation
+
+It installs in two halves. The **plugin** holds the three skills and the canvas app. The **toolkit** the skills call by name is one more command, once per machine.
+
+### Claude Code
+
+```bash
+/plugin marketplace add ReScienceLab/super-prototyping
+/plugin install super-prototyping@super-prototyping
+```
+
+### Other agents
+
+| Your agent | Install the plugin |
+|---|---|
+| **Codex** | `codex plugin marketplace add ReScienceLab/super-prototyping` then `codex plugin add super-prototyping@super-prototyping` |
+| **WorkBuddy / CodeBuddy** | `codebuddy plugin marketplace add ReScienceLab/super-prototyping` then `codebuddy plugin install super-prototyping --scope user` |
+| **Hermes** | `hermes plugins install ReScienceLab/super-prototyping --enable` |
+| **Pi** | `pi install git:github.com/ReScienceLab/super-prototyping@super-prototyping--v<version>` |
+| **Trae**, and anything else that reads `SKILL.md` | `npx skills add ReScienceLab/super-prototyping` |
+
+### Then the toolkit, from any of them
+
+```bash
+uv tool install "git+https://github.com/ReScienceLab/super-prototyping#subdirectory=tools"
+```
+
+One skills tree, a thin manifest per product, so a skill is never forked to be ported. Both halves carry the same version, and `sp-canvas start` prints the line to run when they drift apart.
+
+**A smaller install.** The full one is about 151 MB, because the repo is also the workspace holding those fourteen example boards. Declare the marketplace in `~/.claude/settings.json` with `sparsePaths` for `.claude-plugin`, `skills`, `canvas`, `tools` and `mockups/canvases/templates`, and Claude Code clones just those directories — **6.7 MB installed**, against 151 MB.
+
+---
+
+## Why This Sits Next to OPC Skills
+
+OPC Skills is about a one-person company doing the work of a team. The gap that keeps showing up is design: you can ship the backend, the deploy and the landing copy alone, and still have no way to see the product before building it.
+
+super-prototyping closes that gap without adding a design tool to the stack. The boards are HTML you already know how to read, they live in your repo, they diff in git, and the agent that builds them is the agent already in your terminal.
+
+It is a separate repo with its own release cadence, its own homepage at [prototyping.rescience.com](https://prototyping.rescience.com) and an Apache-2.0 licence — so it is featured on opc.dev rather than folded into the skills library.
+
+---
+
+## FAQ
+
+### Do I need Figma or any design tool?
+
+No. Boards are `.html` files the canvas reads straight from a directory. No registry, no build step, no design tool.
+
+### Is this just "screenshot to code"?
+
+No — that is the thing it is built against. Screenshot-to-code infers values. `clone-prototype` measures them, records the evidence per token, then re-renders and diffs the result against the capture until the numbers agree.
+
+### Does it only do iOS?
+
+The iPhone frame is a built-in spec (393 × 852 pt), but a board is arbitrary self-contained HTML inside a 478 × 980 shape box. Web and desktop screens work the same way.
+
+### Can I design screens that don't exist yet?
+
+That is `new-ui-mock`: new screens built on the same measured token block, including the empty, loading and error states, and side-by-side proposals.
+
+---
+
+## Getting Started
+
+1. **Install the plugin** for your agent, then the toolkit with `uv tool install`
+2. **Start a project**: copy `mockups/canvases/templates` into `mockups/canvases/<slug>` and run its `gen.py`
+3. **Run the canvas**: `sp-canvas start`
+4. **Hand your agent screenshots** and ask for the `clone-prototype` skill
