description: "Dark-canvas product system built on #020618 with #00dc82 as the single brand accent. Type anchored in Public Sans at 72px / weight 700. Extracted automatically from https://nuxt.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
narrative: |
  nuxt.com is built on a mid-dark canvas (oklch(0.129 0.042 264.695)).
  The system uses rgb(0, 220, 130) as the high-saturation accent for primary actions.
  Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside Public Sans as the primary typeface.
  Public Sans is paired with Public Sans Fallback: BlinkMacSystemFont for secondary roles.
  A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy.
  Motion is a first-class concern — 75 keyframe animations plus transition-driven interactions.

# Design System — nuxt.com
> Extracted automatically by Prism from https://nuxt.com
> 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. Signals: button labels look like filenames (app.vue); only 0 card component detected. Treat the component, color and copy values below with caution, and re-extract the canonical marketing URL if fidelity matters.


## 0. Design DNA

**Density**: sparse  |  **Motion**: animated  |  **Weight**: heavy  |  **Aesthetic**: product-neutral

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (Public Sans) | "The Full-Stack" |
| Color assertion | dual-accent | #00dc82 |
| Whitespace | sparse | section rhythm 64px |
| Interaction | animated | 75 keyframes, 13 transitions |
| Radius language | 6px-rounded | from token scale |

**Prism fingerprint**: `neutral-canvas · sans-display · dual-accent · 6px-rounded · animated-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `oklch(0.129 0.042 264.695)` is the page background. Every component composits against this.
> - **Accent**: `rgb(0, 220, 130)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 64px between major bands. Card padding: 44px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.

## 1. Visual Theme & Atmosphere

**Signature:** a gradient wash in the hero. This is the brand's most recognizable visual — reproduce it, don't replace it with a generic card or flat panel.

nuxt.com commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is an inky black surface (`#020618`) where surfaces are layered through stepped luminance — each elevated level is slightly less dark than the one beneath it, creating depth without color shifts. 

Typography is anchored in **Public Sans**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. Negative letter-spacing at display sizes (-1.8px at 72px) compresses headlines into engineered blocks, dense and authoritative. 

Body text reads in Light Gray (`#e2e8f0`) (contrast ratio 12.4:1, well above WCAG AA). **#00dc82** (`#00dc82`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Elevation is built from multi-layer shadow stacks (6 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Jet Black (`#020618`)
- Primary typeface: Public Sans
- Primary text: White (`#ffffff`)
- Accent: #00dc82 (`#00dc82`)
- Display: 72px weight 700, letter-spacing -1.8px
- Shadow system: 6 distinct elevation levels
- Custom fonts loaded: Public Sans, Public Sans Fallback: BlinkMacSystemFont, Public Sans Fallback: Segoe UI, Public Sans Fallback: Helvetica Neue, Public Sans Fallback: Arial, Public Sans Fallback: Noto Sans

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Public Sans | 72px | 700 | 1 | -1.8px | Main headline (h1) |
| Body | Public Sans | 16px | 400 | 1.5 | normal | Standard reading text |
| Button Large | Public Sans | 16px | 500 | 1.5 | normal | Button label (16px) |
| Sub-heading | Public Sans | 14px | 600 | 1.43 | normal | Third-level heading (h3) |

### Font Weight Scale

CSS custom properties define 4 explicit weight steps:
- `--font-weight-normal`: `400` — Regular
- `--font-weight-medium`: `500` — Medium
- `--font-weight-semibold`: `600` — SemiBold
- `--font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `72px`, `48px`, `20px`, `18px`, `16px`, `15px`, `14px`, `12px`, `11px`, `10px`

> 6 size(s) detected outside the sampled hierarchy (48px, 20px, 18px, 15px, 11px, 10px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Button**:
  - **focus:** shadow level changes
- **FooterLink**:
  - **hover:** text #90a1b9 → #90a1b9, border changes

*State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*

```yaml
component-behaviors:
  button:
    default:
      bg: "oklab(0.786145 -0.174855 0.0792278 / 0.1)"
      fg: "rgb(0, 220, 130)"

| base | 32px |
| lg | 44px |
| xl | 48px |
| 2xl | 64px |
| 3xl | 80px |

### 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 | `6px` |
| Inputs & Forms | `6px` |
| Status Badges | `6px` |
| Tabs | `8px` |
| Code Blocks | `0px` |
| Page Body | `0px` |
| Navigation | `0px` |
| Primary Input | `6px` |

**Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill.

**Full Radius Spectrum**: 0px, 4px, 6px, 7px, 8px, 16px (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~128px internal vertical padding (up to 128px) — **very airy / premium**. (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** | `80px` | Top/bottom of full-bleed hero sections |
| **section** | `48px` | Between major bands (color change, content shift) |
| **subsection** | `44px` | Within a section, between content groups |
| **card** | `16px` | 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).

**6/8 structural patterns detected.**

### Hero Pattern

- **Composition:** left-aligned — 
- **Viewport coverage:** 540px tall (not full-viewport)
- **Heading:** "The Full-StackVue Framework" — 72px left-aligned
- **CTAs:** 2 (primary: "Get started")
- **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:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 48px
- **Logo:** ✗ absent
- **Nav links:** 6 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 10 cards detected
- **Columns (desktop):** 2-up grid
- **Card dimensions:** 695×436px (aspect 1.59:1)
- **Gap:** 0px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 2-column grid (desktop) with cards at ~1.59:1 aspect ratio. Each card has an image at the top.

### Testimonial Pattern

- **Count:** 1 testimonial blocks
- **Layout:** single-feature
- **Avg quote length:** 197 chars (medium quote)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
- **Clone instruction:** Build a single-feature of 1 testimonials.   

### CTA Banner Pattern

- **Banner count:** 6
- **Position:** multiple
- **Visual treatment:** ✓ gradient fill
- **Primary CTA text:** "Start reading docs"
- **Clone instruction:** Place multiple CTA banners across page sections. Use gradient background.

### Footer Pattern

- **Columns:** 3
- **Links:** 14 total
- **Height:** 297px
- **Includes:** ✓ newsletter signup | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 3-column footer with ~5 links per column, newsletter signup, social media links, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Inset (Level 1) | `oklab(0.786145 -0.174855 0.0792278 / 0.25) 0px 0px 0px 1px inset` | Buttons, pressed-state elements |
| Inset (Level 2) | `oklch(0.372 0.044 257.287) 0px 0px 0px 1px inset` | Buttons, pressed-state elements |
| Subtle (Level 3) | `oklch(0.279 0.041 260.031) 0px 0px 0px 1px` | Cards, dividers, borders |
| Layered (Level 4) | <br>`rgba(0, 0, 0, 0.05) 0px 1px 2px 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-in` | `cubic-bezier(.4,0,1,1)` | Custom Ease — Balanced |

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `200ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 75 unique animations (75 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 dark background (`#020618`) as the foundation — this is a dark-mode-native design
- Use Public Sans as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-1.8px) at display sizes for compressed, editorial headlines
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use Primary (`#00dc82`) as the primary accent — it's the brand's signature interactive color
- Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
- Maintain nav height at 48px — consistent vertical space for the navigation bar
- Respect the 4px–48px spacing range — the design uses a wide scale for visual breathing room
- Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Each card includes a top image — imagery is part of the card identity, not optional
- Repeat the primary CTA across 6 banner sections — conversion paths are layered, not single
- Include a newsletter signup in the footer — email capture is part of the conversion funnel

### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't increase letter-spacing on headings — the type is designed to run tight at scale
- 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 over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't make the nav sticky — this design lets it scroll away to maximize content focus
- 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 `oklch(0.129 0.042 264.695)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'oklch(0.129 0.042 264.695)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(0, 220, 130)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(0, 220, 130)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Tablet | 1024px | Multi-column grids begin |
| Ultra-wide | 2400px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `72px` | `48px` |
| heading | line-height | `72px` | `48px` |
| heading | letter-spacing | `-1.8px` | `-1.2px` |
| nav | height | `48px` | `auto` |

### Collapsing Strategy
- Headlines: 72px → 48px 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: 4px 6px 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):

- **Card grid: 2-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.*

- **Canvas / 2D rendering** — animated/interactive canvas (charts, graphs, particle fields). Reproduce as live data-viz (e.g. an animated SVG/Canvas line chart), NOT a static image.
- **WebGL** — GPU 3D/shader graphics (hero atmosphere is rendered, not a flat gradient).
- **Glassmorphism** — 1 frosted/blur layer(s) (e.g. `blur(8px)`).
- **Clip-path shapes** — 8 non-rectangular cut(s).
- **CSS-variable animations** (5) — animated custom properties.

> **Motion fingerprint**: WebGL/3D canvas, glassmorphism (1 layers), non-rectangular shapes (10)

## 9b. Visual Tone & Photography

**Tone:** Photography-driven

The site is dominated by photography (JPG/WebP). Photos carry the brand voice as much as the typography. Use authentic, brand-appropriate imagery — generic stock will degrade quality.

**Canonical Brand Image (OG):**
- https://nuxt.com/new-social.jpg
  *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): 11 (100%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)

**Media Format Mix:**
- WebP: 10 (optimized photo/illustration hybrid)
- SVG: 2 (icons, illustrations, decorative geometry)

**Average rendered image size:** 635×371px
**Above-fold image count:** 0 / 11

**Decorative Patterns Detected:**
- 1 large decorative SVG shape (≥200×200px, non-icon) — likely blob/illustration accents
- 22 background patterns (non-photo url() backgrounds) — textures/illustrations as backdrops
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic

**Clone instruction for decorative work:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces.

**Imagery Guidance for clones:**
- Source authentic photography (or licensed stock that matches the brand mood) — placeholders will visibly degrade the clone.
- Match the dominant aspect ratio (see above) so card grids and hero compositions hold.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Jet Black (`#020618`)
- Primary text: Light Gray (`#e2e8f0`)
- Accent: #00dc82 (`#00dc82`)
- Border: Translucent White (8%) (`rgba(255, 255, 255, 0.08)`)
- Font: Public Sans
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Jet Black background (#020618). Headline at 72px Public Sans weight 700, line-height 1, letter-spacing -1.8px, color #e2e8f0."
- "Create the primary CTA button: `#00dc82` background, `#00dc82` text, 4px border-radius, 4px 6px padding, 600 weight, Public Sans font."
- "Build navigation: relative on `#020618`. Public Sans 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Jet Black (`#020618`) — every component is composited against this exact base.
2. **Typography**: All type in Public Sans, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: #00dc82 (`#00dc82`) — one accent, applied consistently to CTAs, active states, and links. Never introduce a second saturated color.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Timing: 150ms for micro-interactions, 150ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `4px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (4px–48px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
7. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent.

**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:
    - "Chosen by leading companies worldwide"
    - "Everything you need, nothing you don't"
    - "Built by developers around the world"
  sub-headings:
    - "Community"
  ctas:
    - "v4.4.8"
    - "Ask Nuxi"
    - "Get started"
    - "Nuxt in 100 seconds"
    - "Minimal"
    - "Routing"
    - "app"
    - "app.vue"
  navigation:
    - "Docs"
    - "Modules"
    - "Templates"
    - "Resources"
    - "Enterprise"
    - "Updates"
    - "60.4K"
  footer-links:
    - "Nuxters"
    - "Nuxt on X"
    - "MIT License"
```

**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:
  logo:
    count: 4
    avg-ratio: 2.77
    common-aspect: "~16:6 banner"
    sample-alts:
      - "Dassault Systemes logo"
      - "Blizzard logo"
      - "Vans logo"
  product:
    count: 1
    avg-ratio: 1.17
    common-aspect: "~1:1 square"
    sample-alts:
      - "Deploy anywhere"
  thumbnail:
    count: 23
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Evan You"
      - "ui"
      - "content"
```

**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
<button class="btn btn-primary">
  v4.4.8
</button>
```
_Source pattern detected: padding `4px 6px` · radius `4px` · weight `600`_

**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** 4 · **cta** 1 · **docs** 2 · **blog** 1 · **project** 3 · **social** 12 · **footer** 13 · **other** 24

**Primary actions (conversion path):**
- Primary call-to-action — "Get started" (the conversion path) → `https://nuxt.com/docs/getting-started/installation`

**Signals:** 17/60 links carry a featured image · dominant link roles: inline-link (24), footer-link (13), social-link (12).

## Extraction Completeness: 85/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 21 | 25 | 15 named colors |
| Typography | 18 | 20 | 7 roles defined |
| Components | 20 | 20 | 5 specs extracted |
| Motion & Interaction | 15 | 15 | Keyframes, easing vars |
| CSS Custom Properties | 10 | 10 | 309 vars |
| Responsive Breakpoints | 2 | 5 | 2 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:*

- **Limited breakpoint data** — fewer than 3 media query breakpoints detected. The site may use fluid CSS (clamp/vw) or container queries for responsiveness rather than traditional breakpoints.

| 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 |
| **Dark mode** | Dark surface is the canonical medium; no separate light-mode variables detected | The dark canvas IS the design — reproduce it as the default. Do not generate a light-mode variant unless explicitly requested |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 309 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 7 typography roles inferred |
| §4 Components | High | 5 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 21 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | Medium | 2 breakpoints detected |
| §9b Photography | Medium | 11 images, hero not detected |

### Brand Gradient Palette

**1 complex gradients captured** from the site's CSS. The first few are the most prominent visual decorations:

```css
/* Gradient 1 */
background: linear-gradient(to bottom,var(--tw-mask-bottom-from-color);

```

### Hover State CSS (Intercepted)

**1 hover rule lines** captured from CSS files. Key interactive transitions from real CSS (not inferred):

```css
@layer properties{@supports ((-webkit-hyphens:none) and (not (margin-trim:inline))) or ((-moz-orient:inline) and (not (color:rgb(from red r g b)))){*,::backdrop,:after,:before{--tw-border-spacing-x:0;--tw-border-spacing-y:0;--tw-translate-x:0;--tw-translate-y:0;--tw-translate-z:0;--tw-rotate-x:initial;--tw-rotate-y:initial;--tw-rotate-z:initial;--tw-skew-x:initial;--tw-skew-y:initial;--tw-space-y-reverse:0;--tw-space-x-reverse:0;--tw-divide-y-reverse:0;--tw-border-style:solid;--tw-gradient-position:initial;--tw-gradient-from:#0000;--tw-gradient-via:#0000;--tw-gradient-to:#0000;--tw-gradient-stops:initial;--tw-gradient-via-stops:initial;--tw-gradient-from-position:0%;--tw-gradient-via-position:50%;--tw-gradient-to-position:100%;--tw-mask-linear:linear-gradient(#fff,#fff);--tw-mask-radial:linear-gradient(#fff,#fff);--tw-mask-conic:linear-gradient(#fff,#fff);--tw-mask-left:linear-gradient(#fff,#fff);--tw-mask-right:linear-gradient(#fff,#fff);--tw-mask-bottom:linear-gradient(#fff,#fff);--tw-mask-top:linear-gradient(#fff,#fff);--tw-mask-top-from-position:0%;--tw-mask-top-to-position:100%;--tw-mask-top-from-color:#000;--tw-mask-top-to-color:transparent;--tw-mask-right-from-position:0%;--tw-mask-right-to-position:100%;--tw-mask-right-from-color:#000;--tw-mask-right-to-color:transparent;--tw-mask-bottom-from-position:0%;--tw-mask-bottom-to-position:100%;--tw-mask-bottom-from-color:#000;--tw-mask-bottom-to-color:transparent;--tw-mask-left-from-position:0%;--tw-mask-left-to-position:100%;--tw-mask-left-from-color:#000;--tw-mask-left-to-color:transparent;--tw-leading:initial;--tw-font-weight:initial;--tw-tracking:initial;--tw-ordinal:initial;--tw-slashed-zero:initial;--tw-numeric-figure:initial;--tw-numeric-spacing:initial;--tw-numeric-fraction:initial;--tw-shadow:0 0 #0000;--tw-shadow-color:initial;--tw-shadow-alpha:100%;--tw-inset-shadow:0 0 #0000;--tw-inset-shadow-color:initial;--tw-inset-shadow-alpha:100%;--tw-ring-color:initial;--tw-ring-shadow:0 0 #0000;--tw-inset-ring-c

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 1512 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**2 breakpoints** read from the live `@media` rules (not guessed):
`1024px` · `2400px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×925 · `14px`×422 · `12px`×69 · `18px`×29 · `15px`×28 · `48px`×24 · `20px`×7 · `72px`×5

**Radius scale** (× = paint count): `6px`×98 · `8px`×64 · `4px`×14 · `16px`×1

**Weights** (× = paint count): `400`×1059 · `500`×264 · `600`×165 · `700`×23

**Layout gaps** (× = paint count): `6px`×67 · `4px`×55 · `8px`×53 · `12px`×30 · `16px 32px`×30 · `64px`×10 · `12px 24px`×6 · `16px`×5

**Elevation (real shadows)**:
```css
oklch(0.279 0.041 260.031) 0px 0px 0px 1px
oklch(0.372 0.044 257.287) 0px 0px 0px 1px inset
oklab(0.786145 -0.174855 0.0792278 / 0.25) 0px 0px 0px 1px inset
rgba(0, 0, 0, 0.05) 0px 1px 2px 0px
```

### Provenance — measured styles on key elements
Read from the live CSSOM (includes runtime-injected CSS). This is *what actually styles the page*, by element:

```css
body { background-color:var(--ui-bg); color:var(--ui-text) }
header { background-color:var(--ui-bg) }
header { background-color:color-mix(in oklab,var(--ui-bg) 75%,transparent) }
nav { gap:calc(var(--spacing)*1.5) }
h1 { font-size:var(--text-5xl) }
h1 { font-weight:var(--font-weight-bold) }
h1 { color:var(--ui-text-highlighted) }
@media (min-width: 40rem) h1 { font-size:var(--text-7xl) }
h2 { font-size:var(--text-lg) }
h2 { font-weight:var(--font-weight-medium) }
h2 { color:var(--ui-text-muted) }
button { gap:calc(var(--spacing)*.5) }
```

> Selectors normalised to their semantic element — source class names are often build-hashed (`.bgDIHX`) and not reusable. The declarations + CSS vars are the transferable part.
