Adds a full annotation pipeline to /impeccable live. On Go, the browser
captures the selected element as a PNG (with annotations composed in),
uploads it to the live helper, and sends the generate event with the
screenshot path so the agent reads user intent visually instead of from
HTML alone.
Annotation tools (while an element is picked):
- Click inside the outline to drop a magenta comment pin with a text input
- Drag to paint a magenta SVG stroke (5 px click-vs-drag threshold)
- Click a pin to edit; double-click to delete; drag a pin to reposition
- Click a stroke to delete it (wider invisible hit path)
- Clear chip top-right wipes everything; hidden when no annotations
Capture pipeline:
- modern-screenshot vendored as an IIFE (scripts/modern-screenshot.umd.js)
and lazy-loaded from the live helper
- Font fix: cross-origin @font-face rules are fetched and fonts are inlined
as base64 data URIs before being handed to modern-screenshot via
font.cssText, since SVGs rasterized via canvas can't fetch external
resources (fix for "Impeccable" rendering bold-serif and items wrapping
wrong in the capture)
- Annotations are temporarily attached to the live element (not only the
clone) so computed styles resolve during the embed pass
- Session screenshots live in .impeccable-live/annotations/session-*/ in
the project root (gitignored) so the agent's Read tool doesn't trip a
per-path permission prompt
Loading shader (activates during GENERATING):
- WebGL overlay rendering the captured PNG as a halftone — cells with
luma-driven dot radius, rendered on paper-cream underneath a magenta
roller that sweeps top-to-bottom with a 3.4s cycle and clean overshoot
- Fixed asymmetric bandAt() using one-sided smoothsteps (previous reversed
smoothstep was undefined on d>0, giving "trail=1 everywhere below")
- Graceful <img> fallback when WebGL is unavailable; prefers-reduced-motion
freezes the band at t=0
Server:
- POST /annotation endpoint (raw image/png body, token + eventId query),
session-scoped tmpdir cleaned up on shutdown
- GET /modern-screenshot.js serves the vendored UMD with aggressive caching
- Optional screenshotPath / comments / strokes fields on generate events
- Fixed pre-existing /source crash on ENOENT (writeHead called twice)
Agent side:
- reference/live.md step 0 tells the agent to Read the screenshot first,
with four rules for interpreting annotations: comments are position-
anchored and scoped to the sub-element under their {x,y}; strokes are
gestures (loop=focus, arrow=direction, cross=delete); comments and
strokes are independent unless adjacent; don't silently guess on
ambiguous strokes
Also:
- Generating bar no longer claims "Generating 1 of 3..." (variants arrive
atomically) — now says "Generating N variants..."
- tests/live-server.test.mjs fixed to read the PID file from project root,
matching the server; adds coverage for the new endpoints and validator
fields
- .impeccable-live/ added to .gitignore

Groundwork for new /skills, /anti-patterns, /tutorials sections.
No user-visible changes yet — this is pure plumbing.
- Split main.css into tokens.css (design tokens + reset, ~100 lines) and
main.css (everything else, imports tokens.css). Lets sub-pages import
only tokens without pulling in the landing-page component CSS.
- Add marked as a dependency.
- Add scripts/lib/render-markdown.js: marked wrapper with a custom link
resolver (skill slugs, reference/*.md anchors, external rel=noopener),
stable heading slugger, and terminal-style code blocks.
- Add scripts/lib/render-page.js: page shell wrapper that injects the
shared site header partial with aria-current marking.
- Add content/site/partials/header.html: shared site header with nav
(Home / Skills / Anti-Patterns / Tutorials / Gallery / GitHub).
- Add public/css/sub-pages.css: shared styles for generated pages, with
.site-header styling (sticky, backdrop blur, accent-underlined active
nav item) and mobile collapse.
Build still produces the same 104 KB landing-page CSS chunk; tests pass.
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)

New detections (browser-only, DOM-based):
- line-length: text wider than ~85 chars per line
- cramped-padding: <8px padding in bordered/bg containers (2+ borders)
- tight-leading: line-height < 1.3x on body text
- small-target: interactive elements < 44x44px
- skipped-heading: heading levels that skip (h1 then h3)
- justified-text: text-align: justify without hyphens: auto
- tiny-text: font-size < 12px on body text (>20 chars)
- all-caps-body: text-transform: uppercase on >30 chars of body text
- wide-tracking: letter-spacing > 0.05em on non-uppercase body text
Browser overlay improvements:
- Hover swaps label for detail tooltip (CSS-based, not JS events)
- Border goes transparent on hover to reveal element underneath
- Fixtures: quality-should-flag.html and quality-should-pass.html

Cloudflare Pages build environment doesn't have the zip CLI tool,
causing zip bundle creation to fail silently. Switched to the archiver
npm package for cross-platform zip generation.

Replace Vercel serverless functions with Cloudflare Pages static
rewrites and lightweight download functions. Pre-generate all API
JSON data at build time for zero-invocation static serving. Also
fix stale simplify→distill rename in framework-viz periodic table.

- Remove Tailwind CSS and related dependencies (tailwindcss, @tailwindcss/cli, bun-plugin-tailwind)
- Remove unused dependencies (lenis, @paper-design/shaders, three)
- Convert @theme variables to CSS custom properties in :root
- Add minimal CSS reset for browser consistency
- Update server to serve /css/* and /js/* routes directly
- Fix conflicting CSS rules that broke commands section layout
- Delete bunfig.toml (no longer needed without Tailwind plugin)
The site now uses native CSS imports via Bun's built-in bundler,
eliminating the need for separate Tailwind compilation step.
