Four changes driven by human design review of eval artifacts:
1. Static engine contrast fidelity (nav-CTA cascade miss):
- parseAnyColor evaluates color-mix() (premultiplied sRGB mix; exact
for the dominant `color-mix(in oklab, C n%, transparent)` chip form)
- extractStaticColor captures color-mix() balanced instead of plucking
"transparent" out of the expression
- resolveBackground composites translucent layers over the opaque base
in both engines instead of skipping (static) or returning them
as-if-opaque (browser)
- NEW hover pass in the static cascade: :hover rules are matched via
state-stripped selectors, merged per-property against the resting
cascade with real specificity, and checked for WCAG contrast on
styled controls (checkHoverContrast). Catches the recurring miss
where a broader selector (.nav-links a:hover) beats the CTA's own
hover color and drops the pair below AA.
2. New `radial-halo` slop rule: chromatic radial-gradient wash (visible
saturated center -> transparent) as a decorative background on a dark
page. Exempts achromatic vignettes, opaque-end sheens, px-stop dot
textures, url() photo layers, and translucent (<0.7 alpha) staged-
light washes. Separate id from dark-glow so dashboards track the
gradient-drawn variant independently.
3. side-tab horizontal variant: 3-12px chromatic border-top/bottom (and
top/bottom-anchored full-width pseudo stripes) on cards/badges flag as
side-tab. Exempt: tablist/nav/aria-selected underlines, link/button
affordances, table cells, hr, state-conditional pseudo stripes, and
>12px bands. Badge-shaped spans (own visible background) participate.
4. CLI: file:// URLs route to the Puppeteer browser engine (~2s on a
50KB page), and detect --json findings now carry the registry
`category` field so downstream QA loops can separate mechanical slop
tells from judgment calls.
Fixture policy update: flat 3px top-accent cards moved from should-pass
to flag columns; tablist-underline and 16px-band pass cases added.
Browser bundle regenerated.

Merges the impeccable-detect CLI repo (pbakaus/impeccable-cli@831a6cc)
into this repo. The BSL-1.1 license that motivated the split is gone;
everything is now Apache 2.0.
- Add bin/, src/, detection tests and fixtures from CLI repo
- Merge package.json: name → "impeccable", add bin/exports/files fields
- Internal refs now read from local src/ instead of node_modules/
- Update SPDX headers, NOTICE.md, CLAUDE.md, FAQ, npm README
- Add prepack/postpack scripts for CLI-focused README on npm
- Remove terminal license labels (no longer needed)

The skill sync wipes .claude/skills/ and re-copies from dist, deleting
the generated browser script. Moved build-browser-detector.js to run
AFTER the sync. Dev server's /js/* route now falls through to
.claude/skills/critique/scripts/ for built artifacts. All fixture HTML
references use /js/detect-antipatterns-browser.js (clean URL).

The generated browser detector now lives alongside the CLI script in
.claude/skills/critique/scripts/ — clearly a build artifact, not a
hand-maintained source file in public/js/.
- build-browser-detector.js outputs to .claude/ instead of public/js/
- Dev server serves .claude/skills/* for local testing
- All fixture and antipattern-example HTML files updated to new path
- Puppeteer detectUrl reads browser script from same directory
- Browser parity test server updated to serve from .claude/
- Deleted public/js/detect-antipatterns-browser.js

Architecture simplified to two paths:
- HTML files: jsdom with getComputedStyle (resolves linked CSS, cascade)
- Non-HTML files: regex fallback (CSS, JSX, TSX, etc.)
- URLs: Puppeteer (unchanged)
- --fast flag forces regex-only for all files
Removed --deep flag (jsdom is now the default). Removed static mode
from browser script (always uses getComputedStyle — it's in a real
browser). Anti-pattern definitions split into:
- checkElementBorders() — shared element-level computed style checker
- checkPageTypography() — shared page-level checker
- REGEX_MATCHERS/REGEX_ANALYZERS — regex fallback for non-HTML
Browser script simplified from 470 lines to 250. CLI script reduced
from 810 lines to 440. Detection logic is now single-source for
jsdom/puppeteer/browser.
Fixtures now served via /fixtures/* route in dev server for proper
CORS handling of linked stylesheets.

- Anti-pattern detector script (source/skills/critique/scripts/detect-antipatterns.mjs):
CLI tool that scans files/dirs for UI anti-patterns via regex. Detects side-tab
accent borders and border-accent-on-rounded patterns across Tailwind, CSS, JSX.
Context-aware: skips safe elements (blockquotes, nav, inputs, code), neutral
colors, and adjusts thresholds based on border-radius co-occurrence.
- Browser visualizer (public/js/detect-antipatterns-browser.js):
Drop-in script that highlights anti-patterns directly in the browser with
labeled overlays. Two modes: "static" (regex, matches CLI) and "computed"
(getComputedStyle, catches CSS cascade). Scans both inline styles and
<style> blocks.
- Gallery of Shame (public/gallery.html):
Standalone page showcasing 11 AI anti-pattern examples with thumbnails
and links. Anti-pattern example pages updated from 1080x1080 Twitter
format to responsive layouts, labels removed, screenshots retaken at 16:10.
- Critique skill updated to run detector before manual review.
- Build system: skills now support scripts/ directories alongside reference/.
All 8 provider transformers refactored to use shared.js (DRY).
- 58 new tests covering detection logic, fixtures, CLI integration.
