--- version: alpha name: playwright.dev description: "Light product system built on #ffffff with #ffffff as the primary CTA accent. Type anchored in system-ui at 60px / weight 700. Extracted automatically from https://playwright.dev/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | playwright.dev is built on a pure-white canvas (rgb(255,255,255)). The system uses rgb(255, 255, 255) as the singular interactive color. Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside system-ui as the primary typeface. A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page. Motion is a first-class concern — 6 keyframe animations plus transition-driven interactions. colors: background: "#ffffff" surface-1: "#f5f5fa" surface-2: "#eeeeee" ink: "#1c1e21" ink-muted: "rgba(28, 30, 33, 0.65)" ink-subtle: "#8b949e" primary: "#ffffff" on-primary: "#111111" primary-focus: "#005fcc" semantic-error: "#fd9c9f" semantic-success: "#008b00" semantic-warning: "#e6a700" semantic-info: "#87d8f2" typography: display-xl: fontFamily: "system-ui" fontSize: 60px fontWeight: 700 lineHeight: 1.25 letterSpacing: 0 display-lg: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 60px fontWeight: 700 lineHeight: 1.25 letterSpacing: 0 display-md: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 20px fontWeight: 700 lineHeight: 1.25 letterSpacing: 0 headline: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 700 lineHeight: 1.25 letterSpacing: 0 body: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: 1.65 letterSpacing: 0 body-sm: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 14px fontWeight: 500 lineHeight: 1.65 letterSpacing: 0 button: fontFamily: "Ubuntu, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 500 lineHeight: 1.65 letterSpacing: 0 rounded: none: 0px xs: 4px sm: 8px md: 14px lg: 20px xl: 32px pill: 9999px spacing: xxs: 2px xs: 4px sm: 8px md: 12px lg: 32px xl: 48px xxl: 88px components: button-light--invert: backgroundColor: "{colors.primary}" textColor: "#5e6a75" typography: "{typography.headline}" rounded: "{rounded.sm}" padding: 0px 8px button-light--invert-2: backgroundColor: "{colors.surface-2}" textColor: "#333333" typography: "{typography.headline}" rounded: "{rounded.xs}" padding: 3px 10px 3px 8px button-light--invert-3: backgroundColor: "{colors.primary}" textColor: "{colors.ink-muted}" typography: "{typography.headline}" rounded: "{rounded.none}" padding: 8px 16px card-standard-card: backgroundColor: "transparent" typography: "{typography.headline}" rounded: "{rounded.none}" padding: 0px 16px navigation-main-nav: backgroundColor: "transparent" typography: "{typography.headline}" rounded: "{rounded.none}" padding: 80px 0px code-block-inline-code--pre: backgroundColor: "#f6f7f8" textColor: "{colors.ink-muted}" typography: "{typography.body-sm}" rounded: "{rounded.xs}" padding: 8px 12px extracted_at: "2026-06-11T06:14:25.699Z" completeness: 91 scoreVersion: "v2" --- # Design System — playwright.dev > Extracted automatically by Prism from https://playwright.dev > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). > ⚠️ **LOW-CONFIDENCE CAPTURE** — this extraction likely sampled an app shell / interactive demo, **not** the marketing page.

This is the brand's most recognizable visual — reproduce it, don't replace it with a generic card or flat panel. playwright.dev uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. Headlines are set in **system-ui**, a sans-serif display face (the dominant type signature, e.g. "enables reliable web automation for testing, scripting, and " at 60px). Body text is set in **Roboto**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. Body text reads in Near-Black (`#1c1e21`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Pure White** (`#ffffff`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (2 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI. Motion design uses smooth easing curves for polished state transitions. **Key Characteristics:** - Background: Pure White (`#ffffff`) - Primary typeface: Ubuntu - Primary text: Near-Black (`#1c1e21`) - Accent: Pure White (`#ffffff`) - Display: 60px weight 700 - Shadow system: 2 distinct elevation levels ## 2.

Component Behaviors (State Matrix) ### Interaction State Narrative *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.* ```yaml component-behaviors: button: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(28, 30, 33)" link: default: bg: "rgb(255, 255, 255)" fg: "rgb(28, 30, 33)" navLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(28, 30, 33)" footerLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(235, 237, 240)" hover: bg: "transparent" fg: "inherit" ``` **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand. ## 4c. Component Vocabulary (Closed System) *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.* ### Buttons - **2 shape(s)** in this system: `Light / Invert`, `Subtle` - **DO NOT introduce new buttons variants** without justification ### Cards & Containers - **1 shape(s)** in this system: `Standard Card` - **DO NOT introduce new cards & containers variants** without justification ### Navigation - **1 shape(s)** in this system: `Main Nav` - **DO NOT introduce new navigation variants** without justification ### Code Blocks - **1 shape(s)** in this system: `Inline Code / Pre` - **DO NOT introduce new code blocks variants** without justification ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 1140px ### Spacing System Generous spacing — editorial breathing room | Token | Value | |-------|-------| | xxs | 2px | | xs | 4px | | sm | 8px | | md | 12px | | base | 16px | | lg | 32px | | xl | 48px | | 2xl | 80px | | 3xl | 88px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 4px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 14px | Cards, containers | | Lg | 20px | Large rounded elements, pill segments | | Xl | 32px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `8px` | | Cards & Containers | `0px` | | Navigation | `none` | | Code Blocks | `6px` | | Page Body | `0px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 4px, 6px, 6.4px, 8px (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~48px internal vertical padding (up to 80px) — **standard**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone. *Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.* | Name | Value | Use case | |------|-------|----------| | **hero** | `88px` | Top/bottom of full-bleed hero sections | | **section** | `48px` | Between major bands (color change, content shift) | | **subsection** | `32px` | Within a section, between content groups | | **card** | `12px` | Card padding, list-item spacing | | **compact** | `8px` | Form fields, tight clusters, badge padding | | **micro** | `4px` | Icon-text gap, tag inner padding | **Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.). ## 5c. Widget & Structure Library Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values). **4/8 structural patterns detected.** ### Hero Pattern - **Composition:** left-aligned — - **Viewport coverage:** 225px tall (not full-viewport) - **Heading:** "Playwright enables reliable web automation for testing, scripting, and AI agents." — 60px left-aligned - **CTAs:** none detected in hero (unusual — agent should verify) - **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text. ### Navigation Pattern - **Position:** sticky (stays visible during scroll) - **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right) - **Height:** 60px - **Logo:** ✓ present - **Nav links:** 6 primary items - **CTAs in nav:** 0 (no buttons — links only) - **Theme toggle:** ✓ dark/light mode switcher present - **Clone instruction:** Build a sticky logo left links left navigation. Link-only — no button styling needed. ### Card Grid Pattern - **Card count:** 3 cards detected - **Columns (desktop):** 3-up grid - **Card dimensions:** 440×224px (aspect 1.97:1) - **Gap:** 0px between cards - **Content:** ✗ no image - **Clone instruction:** Build a 3-column grid (desktop) with cards at ~1.97:1 aspect ratio. Text/icon-only cards (no photography). ### Footer Pattern - **Columns:** 3 - **Links:** 13 total - **Height:** 302px - **Includes:** ✗ no newsletter | ✓ social icons | ✓ copyright - **Clone instruction:** Build a 3-column footer with ~4 links per column, social media links, and a copyright line. ## 6. Depth & Elevation | Level | Treatment | Use | |-------|-----------|-----| | Flat (Level 0) | No shadow | Page background, content blocks | | Layered (Level 1) |
`rgba(0, 0, 0, 0.1) 0px 1px 2px 0px` | Cards, elevated surfaces | | Layered (Level 2) |
`rgba(0, 0, 0, 0.2) 0px 5px 40px 0px` | Cards, elevated surfaces | **Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation. ## 7. Motion & Interaction ### Easing System | CSS Variable | Curve | Semantic Name | |--------------|-------|---------------| | `--ease-smooth` | `cubic-bezier(.25,.8,.4,1)` | Custom Ease — Balanced | | `--ease-fast` | `cubic-bezier(.45,.15,.6,.9)` | Custom Ease — Balanced | | `--ifm-transition-timing-default` | `cubic-bezier(.08,.52,.52,1)` | Custom Ease — Balanced | ### Duration Scale | CSS Variable | Value | Tier | |--------------|-------|------| | `--ifm-button-transition-duration` | `.2s` | Normal | ### Copy-Paste Transition Snippets **Color / Background** ```css transition: color 0.2s cubic-bezier(0.08, 0.52, 0.52, 1); ``` **Opacity** ```css transition: opacity 0.2s cubic-bezier(0.08, 0.52, 0.52, 1), transform 0.2s cubic-bezier(0.08, 0.52, 0.52, 1), visibility 0.2s cub...; ``` **Background** ```css transition: background 0.2s; ``` **All Props** ```css transition: 0.2s cubic-bezier(0.08, 0.52, 0.52, 1); ``` ### Keyframe Animation Catalog | Animation Name | Type | Animated Props | Use Hint | |----------------|------|----------------|----------| | `loading-spin_vzvp` | Rotate / Spin | transform | Loading indicator | | `fade-in` | Fade | opacity | Element entrance | | `slideDown` | Fade + Move | opacity, transform | Panel / drawer enter | | `shimmerText` | Custom | background-position-x, background-position-y | Loading placeholder | | `fadeIn` | Fade | opacity | Element entrance | | `pulse` | Fade | opacity | Attention / status | ### Motion Fingerprint - **Speed Character**: Balanced Pacing (median duration: `200ms`) - **Dominant Easing**: custom cubic-bezier curves - **Animation Library**: 6 unique animations (6 total including variants) > This design moves with balanced pacing timing using custom cubic-bezier curves, creating a UI that feels natural and fluid. ## 8. Do's and Don'ts ### Do - Use Near-Black (`#1c1e21`) for text — not pure black, it's warmer and more readable - Use Ubuntu as the primary typeface — it defines the brand personality - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color - Use 8px border-radius on buttons — the standard corner rounding for interactive elements - Keep navigation sticky to the top — the design uses a persistent navigation pattern - Maintain nav height at 60px — consistent vertical space for the navigation bar - Respect the 4px–48px spacing range — the design uses a wide scale for visual breathing room - Make the navigation sticky — it stays visible during scroll, signaling content depth - Include a theme toggle in the nav — dark mode is a first-class feature - Use a 3-column grid on desktop — density matters for this content type ### Don't - Don't use pure black (`#000000`) for text — the near-black adds warmth - Don't substitute with generic sans-serif or serif — the custom font carries the brand - Don't invent new shadow values — use only the extracted shadow levels - Don't introduce additional saturated accent colors — the palette is intentionally controlled - Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence - Don't put a CTA button in the nav — this design uses links only at the top ## 7b. Enforceable Brand Rules *Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.* ```yaml rules: - id: brand-canvas-001 type: do rule: "Always use the page background `rgb(255,255,255)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(255,255,255)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(255, 255, 255)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(255, 255, 255)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile | 420px | Single column, compact spacing | | Mobile Large | 576px | Expanded mobile layout | | Tablet | 768px | Multi-column grids begin | | Tablet | 997px | Multi-column grids begin | | Large Desktop | 1300px | Maximum content width | | Large Desktop | 1440px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `60px` | `36px` | | heading | line-height | `75px` | `45px` | | button | width | `auto` | `30px` | | card | width | `440px` | `390px` | ### Collapsing Strategy - Headlines: 60px → 36px on mobile - Navigation: horizontal links → hamburger menu on mobile - Cards: multi-column → stacked vertical on mobile - Footer: multi-column → stacked single column on mobile ### Touch Targets - Buttons: 0px padding - Navigation: adequate spacing between items - Interactive elements: minimum 44px touch target recommended ### Collapsing Narrative How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions): - **Navigation collapses to hamburger** — 6 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle). - **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile. - **Footer columns collapse:** 3 columns (desktop) → 1 column (mobile). ## 7c. Visual Effects & Dynamic Behavior *The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.* - **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands. > **Motion fingerprint**: CSS scroll-driven animations ## 9b. Visual Tone & Photography **Tone:** Mixed photography + illustration A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents. **Canonical Brand Image (OG):** - https://repository-images.githubusercontent.com/221981891/8c5c6942-c91f-4df1-825f-4cf474056bd7 *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 1 (11%) - Portrait (<0.87): 0 (0%) - Square (0.87–1.15): 7 (78%) - Ultra-wide (>2.3): 1 (11%) **Media Format Mix:** - JPG: 1 (typically photographic content) - PNG: 8 (logos, transparent UI elements, mockups) **Average rendered image size:** 103×68px **Above-fold image count:** 0 / 9 **Decorative Patterns Detected:** - 2 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth - 1 background pattern (non-photo url() backgrounds) — textures/illustrations as backdrops **Clone instruction for decorative work:** Decorative details are subtle — don't over-style; the design relies on restraint. **Imagery Guidance for clones:** - Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents. - Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone. ## 10. Agent Prompt Guide ### Quick Reference - Background: Pure White (`#ffffff`) - Primary text: Near-Black (`#1c1e21`) - Accent: Pure White (`#ffffff`) - Border: Translucent Pure Black (5%) (`rgba(0, 0, 0, 0.05)`) - Font: Ubuntu - Body: 16px weight 400 ### Example Component Prompts - "Create a hero section on Pure White background (#ffffff). Headline at 60px Ubuntu weight 700, line-height 1.25, color #1c1e21." - "Create the primary CTA button: `#ffffff` background, `#1c1e21` text, 9999px border-radius, 10px 20px padding, 700 weight, Ubuntu font." - "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px 16px." - "Build navigation: sticky on `#ffffff`. Ubuntu 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base. 2. **Typography**: All type in Ubuntu, weight range 300–700. Never exceed 700 — heavier weights break the brand's tonal restraint. 3. **Accent**: Pure White (`#ffffff`) is the sole interactive color. On hover → Forest Green (`#1a7e1f`). Use CSS transitions, not opacity/brightness filters. 4. **Focus**: Render focus rings in M Tricolor Blue (`#005fcc`) — never hide focus outlines. The ring color is distinct from the accent to avoid ambiguity. 5. **Motion**: All transitions use `cubic-bezier(0.08,0.52,0.52,1)`. Timing: 200ms for micro-interactions, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality. 6. **Shape**: CTAs at `0px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 7. **Spacing**: Use the `--ca-space-*` token scale (4px–48px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 8. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent. ## 11. CSS Design Tokens Raw Export *Copy-paste ready `:root {}` block — all values extracted directly from the live site.* ```css /* Colors */ :root { --ca-primary: #ffffff; --ca-surface-1: #f5f5fa; --ca-surface-2: #eeeeee; --ca-ink-muted: #1c1e21; --ca-ink-subtle: #8b949e; --ca-on-primary: #111111; --ca-primary-focus: #005fcc; --ca-semantic-error: #fd9c9f; --ca-semantic-success: #008b00; --ca-semantic-warning: #e6a700; --ca-semantic-info: #87d8f2; } /* Typography */ :root { --ca-font-primary: "system-ui", system-ui, sans-serif; --ca-text-display: 60px; --ca-text-heading: 60px; --ca-text-body: 16px; --ca-text-small: 14px; --ca-text-button: 16px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 4px; --ca-space-sm: 8px; --ca-space-md: 12px; --ca-space-base: 16px; --ca-space-lg: 32px; --ca-space-xl: 48px; --ca-space-2xl: 80px; --ca-space-3xl: 88px; --ca-radius-none: 0px; --ca-radius-xs: 4px; --ca-radius-sm: 8px; --ca-radius-md: 14px; --ca-radius-lg: 20px; --ca-radius-xl: 32px; --ca-radius-full: 9999px; } /* Motion */ :root { --ca-ease-smooth: cubic-bezier(.25,.8,.4,1); --ca-ease-fast: cubic-bezier(.45,.15,.6,.9); } ``` ## 13. Page Structure Skeleton *The actual layout the source site uses. Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: hero tag: div height: 3037px width: full-bleed layout: flex-column justify=normal children: 4 vertical-padding: ~32px - section: header tag: header classes: ["hero", "heroBanner_UJJx"] height: 600px width: full-bleed layout: flex-row justify=normal children: 1 bg-treatment: linear-gradient vertical-padding: ~80px (generous) padding: "80px 0px" - section: feature-section tag: div classes: ["theme-layout-main", "main-wrapper", "mainWrapper_z2l0"] height: 2675px width: full-bleed layout: flex-column justify=normal children: 2 vertical-padding: ~80px (generous) - section: feature-section tag: div classes: ["container"] height: 440px width: 1320px layout: block children: 3 padding: "0px 16px" - section: feature-section tag: main height: 2075px width: full-bleed layout: block children: 6 vertical-padding: ~48px - section: content-section tag: section classes: ["pathCards_cPva"] height: 352px width: full-bleed layout: block children: 1 vertical-padding: ~48px padding: "48px 0px" - section: content-section tag: div classes: ["container"] height: 256px width: 1320px layout: block children: 1 padding: "0px 16px" - section: feature-section tag: section classes: ["featureSection_efmM", "featureSectionAlt_XlZb"] height: 409px width: full-bleed layout: block children: 1 bg: "rgb(245, 246, 247)" vertical-padding: ~48px padding: "48px 0px" - section: feature-section tag: div classes: ["container"] height: 313px width: 1320px layout: block children: 2 padding: "0px 16px" - section: feature-section tag: section classes: ["featureSection_efmM"] height: 383px width: full-bleed layout: block children: 1 vertical-padding: ~48px padding: "48px 0px" - section: feature-section tag: div classes: ["container"] height: 287px width: 1320px layout: block children: 2 padding: "0px 16px" - section: feature-section tag: section classes: ["featureSection_efmM", "featureSectionAlt_XlZb"] height: 313px width: full-bleed layout: block children: 1 bg: "rgb(245, 246, 247)" vertical-padding: ~48px padding: "48px 0px" - section: feature-section tag: div classes: ["container"] height: 217px width: 1320px layout: block children: 2 padding: "0px 16px" - section: section tag: section classes: ["crossBrowser_o5jx"] height: 294px width: full-bleed layout: block children: 1 vertical-padding: ~48px padding: "48px 0px" - section: unknown tag: div classes: ["container"] height: 198px width: 1320px layout: block children: 2 padding: "0px 16px" - section: section tag: section classes: ["logosSection_gMWS"] height: 324px width: full-bleed layout: block children: 1 - section: unknown tag: div classes: ["container"] height: 323px width: 1320px layout: block children: 1 padding: "0px 16px" - section: footer tag: footer classes: ["theme-layout-footer", "footer", "footer--dark"] height: 302px width: full-bleed layout: block children: 1 bg: "rgb(48, 56, 70)" tone: dark vertical-padding: ~32px padding: "32px" - section: unknown tag: div classes: ["container", "container-fluid"] height: 238px width: 1320px layout: block children: 2 padding: "0px 16px" ``` **Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block). ## 14. Copy Library (Real Content from Source) *Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.* ```yaml copy: section-headings: - "Built for testing" - "Chosen by companies and open source projects" sub-headings: - "Playwright Test" ctas: - "Node.js" - "Search Ctrl K" - "Star 90k+" - "Star" navigation: - "Playwright" - "Docs" - "MCP" - "CLI" - "API" - "Node.js" - "TypeScript" - "Python" - ".NET" - "Java" footer-links: - "Getting started" ``` **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording. ## 15. Asset Inventory (Image Roles & Ratios) *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.* ```yaml assets: thumbnail: count: 8 avg-ratio: 1.01 common-aspect: "~1:1 square" sample-alts: - "Playwright logo" - "VS Code" - "Bing" ``` **Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`. ## 16. Component HTML Templates *Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.* ### Button (primary action) ```html ``` _Source pattern detected: padding `0px` · radius `0px` · weight `500`_ **Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **nav** 5 · **cta** 1 · **docs** 10 · **social** 11 · **footer** 13 · **other** 5 **Primary actions (conversion path):** - Primary call-to-action — "Get started" (the conversion path) → `https://playwright.dev/docs/intro` **Signals:** 19/45 links carry a featured image · device mockups detected: tablet ×1 · dominant link roles: footer-link (22), inline-link (14), navigation (5). --- ## Extraction Completeness: 91/100 (A) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 25 | 25 | 21 named colors | | Typography | 20 | 20 | 10 roles defined | | Components | 16 | 20 | 4 specs extracted | | Motion & Interaction | 15 | 15 | Keyframes, easing vars | | CSS Custom Properties | 10 | 10 | 779 vars | | Responsive Breakpoints | 5 | 5 | 6 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 12. Known Gaps & Confidence Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback. *Auto-detected extraction limitations — understand before building:* - **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass. | Category | What's missing | Fallback strategy | |----------|----------------|-------------------| | **Hero imagery** | No dominant hero image detected above the fold | Use the canonical brand visual from §9b (OG image) for hero composition | | **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 779 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 10 typography roles inferred | | §4 Components | Medium | 4 component variants captured | | §7 Motion | High | Keyframes + transitions | | §8 Do's/Don'ts | High | 17 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 6 breakpoints detected | | §9b Photography | Medium | 9 images, hero not detected | ## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+) *Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS).
