+            <li><strong>Data-driven skill rewrite.</strong> The core skill (renamed from <code>frontend-design</code> to <code>impeccable</code>) was rebuilt using a multi-model eval framework that runs the skill with and without the improvements across 7 design niches and measures how much the output collapses into monoculture. Not vibes, numbers: on Qwen 3.6 Plus, overused Fraunces headings dropped from 92% to 0% on kids reading, side-tab borders from 76% to 20% on vintage moto, no theme regressions elsewhere. Run <code>/impeccable teach</code> once to set your project's design context.</li>
+            <li><strong>Anti-pattern detection engine.</strong> 25 rules across typography, color &amp; contrast, layout, motion, and design quality. Handles modern color formats (oklch/oklab/lch/lab), CSS variables inside border shorthands, gradient-backed text, and emoji-only nodes — the hard-to-hit cases that slip past regex-only scanners.</li>
+            <li><strong>CLI: <code>npx impeccable detect</code>.</strong> Scans HTML, CSS, JSX/TSX, Vue, Svelte, and CSS-in-JS with framework detection, multi-file import tracking, live URL scanning (via Puppeteer), JSON output for CI, and a <code>--fast</code> regex mode for huge codebases.</li>
+            <li><strong>Chrome DevTools extension.</strong> One-click detection on any page — yours, staging, production, or someone else's. Reads live computed styles, surfaces findings in an interactive panel, and highlights offending elements on the page. In Chrome Web Store review.</li>
+            <li><strong><code>/critique</code> got teeth.</strong> Persona sub-agents now review in parallel, score against Nielsen's heuristics, run the detector automatically, and open a live browser overlay so you can walk each finding on the rendered page.</li>
+            <li><strong>New command: <code>/shape</code>.</strong> Interviews you about purpose, audience, and goals before writing a single line of design — so the AI actually understands the brief instead of jumping straight to CSS.</li>
+            <li><strong>Rebuilt site and docs.</strong> New narrative (Foundation → Language → Antidote → Visual Mode), a browsable <a href="/skills">skills index</a> with per-skill detail pages and before/after demos, <a href="/tutorials">tutorials</a> walk-throughs, an <a href="/anti-patterns">anti-patterns index</a>, and the <a href="/gallery">Gallery of Shame</a> with live detection overlays. Mobile experience overhauled end-to-end.</li>
+            <li><strong>New harness: Rovo Dev.</strong> Brings the total to 11 supported AI tools.</li>
+            <li><strong>Licensing unified to Apache 2.0.</strong> CLI merged back into this repo; every component now ships under a single permissive license.</li>
