This failed because npx requires Playwright as a local project dependency. More fundamentally, installing the npm package can't rewire the stub callbacks, so the install was pointless. Now standalone mode logs a clear warning and continues with no-op browser callbacks. Added --skip-playwright CLI flag to bypass the MCP probe entirely.

Pattern docs (reference-agnostic): - 00-plan.md — token groups, HTML/SCSS/JS rules, prompts-as-md rule, visual-validation hook, pattern vs per-example deliverables - 01-panel-interface.md — PanelComponent + slot components + atoms - 02-decomposition-process.md — algorithm for any reference - 03-visual-validation.md — before/after diff pipeline First tuning example (full-stack-dashboard): - reference.png (1905x953) - decomposition.md — applied Panel tree - regions.json (v4) — 47 bboxes, validated via overlay diagnostic - atoms-delta.md — 6 proposed atoms under review - tuning-notes.md — 11 open observations, 3 added from test run Stage A tooling: - scripts/capture-before.mts — per-region PNG cropper + manifest - scripts/overview-strip.mts — overlay diagnostic - scripts/detect-boundaries.mts — brightness-based probe (kept for research; unreliable on low-contrast designs per tuning-note §8) visual-baselines/full-stack-dashboard/ — 47 baseline PNGs + manifest.json + _overlay.png Deps: pngjs, pixelmatch (+ types) as devDependencies.

The pattern refines; examples accumulate. + +--- + +## 2. Style Guide + +The pattern owns **token groups and their meanings**, not specific values. Every example supplies concrete values in its own `tokens.scss` override that targets these token names. + +### 2.1 Token groups (contract) + +All visual values — colors, spacing, typography, motion — resolve through CSS custom properties under `:root`. Components consume `var(--*)`; they never hold literals. + +| Token group | Names the pattern defines | What each example must supply | +|---|---|---| +| **Color — base** | `--bg-0` (page), `--bg-1` (panel), `--bg-2` (inset), `--line`, `--line-dim` | Concrete hex per theme | +| **Color — text** | `--fg-0`, `--fg-1` (label), `--fg-2` (muted), `--fg-accent` | Concrete hex per theme | +| **Color — state** | `--ok`, `--warn`, `--crit`, `--live`, `--info` | Concrete hex per theme | +| **Color — series** | `--series-1` … `--series-N` | A deterministic chart palette | +| **Space** | `--sp-1` … `--sp-6` | Pixel values following a consistent step | +| **Radius** | `--r-0`, `--r-1` | A "sharp" and a "default" radius | +| **Border** | `--bw-hair`, `--bw-accent` | Hairline and accent widths | +| **Typography** | `--font-mono`, `--font-sans` | One mono, one sans family | +| **Type scale** | `--t-xs` … `--t-xxl` | At least 6 steps; `--t-xxl` is the hero stat | +| **Motion** | `--dur-fast`, `--dur-med`, `--dur-slow`, `--easing` | Durations + one shared easing | + +### 2.2 Theme contract + +- At least one theme must be defined. A second (typically a light/dark counterpart) is optional. +- Theme is activated by a `data-theme=""` attribute on ``. +- Swapping theme is a pure variable swap — no structural changes, no per-theme CSS overrides outside the token file. +- Visual hierarchy (border weight, corner-tick presence, accent positioning) is theme-invariant. + +### 2.3 Visual motifs the pattern guarantees + +These motifs are contracts the pattern enforces; examples may **tune their values** (size, opacity, weight) but must not remove them: + +- **Corner ticks** on every `variant="default"` Frame. Rendered via `::before` / `::after`, not SVG. +- **Header/Body separator** as a horizontal rule (style is example-chosen: solid, dotted, gradient). +- **Label strip** hovering at the Frame's top-left when `label` input is set. +- **Accent underline** available on `` and active nav tabs. +- **Monospace** for all numeric and short-label text; sans reserved for multi-line prose. +- **Uppercase small labels** for KV keys and section markers (tracking ≥ `+0.04em`). +- **Sharp corners** — `--r-1` must be ≤ 4px. + +### 2.4 Iconography + +- Line-art SVG, stroke-based, sized to adjacent line-height. +- Icon color inherits `currentColor` so status drives color without stylesheet swaps. +- Icon names are registered in a per-example registry; the pattern does not prescribe which glyphs exist. + +--- + +## 3. HTML Structure + +### 3.1 Slot projection + +A Panel is declared once in markup with named content-projection slots: + +```html + + … + … + … + +``` + +- Slots are **optional** — omit Header for borderless leaf Panels. +- Frame and Status are not authored — they are rendered by the Panel host. +- Nested Panels are just Panels inside `` — no special syntax. + +### 3.2 Semantic HTML mapping + +| Panel role | Host element | Notes | +|---|---|---| +| Page root | `
