narrative: |
  intercom.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(17, 17, 17) as the singular interactive color.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Saans as the primary typeface.
  A restrained elevation system (1 distinct shadow) — 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.

## 0. Design DNA

**Density**: moderate  |  **Motion**: animated  |  **Weight**: light  |  **Aesthetic**: sharp-architectural

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (Saans) | "The only helpdesk designed for" |
| Color assertion | dual-accent | #111111 |
| Whitespace | moderate | section rhythm 48px |
| Interaction | animated | 6 keyframes, 5 transitions |
| Radius language | 0px-architectural | from token scale |

**Prism fingerprint**: `neutral-canvas · sans-display · dual-accent · 0px-architectural · animated-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(255, 255, 255)` is the page background. Every component composits against this.
> - **Accent**: `rgb(17, 17, 17)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 24px.
> - **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

intercom.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. 

Typography is anchored in **Saans**. Negative letter-spacing at display sizes (-2.4px at 80px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Black (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Near-Black** (`#111111`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (1 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: White (`#ffffff`)
- Primary typeface: MediumLL
- Accent: Near-Black (`#111111`)
- Display: 80px weight 400, letter-spacing -2.4px
- Shadow system: 1 distinct elevation levels
- Custom fonts loaded: MediumLL, MediumLL Fallback, IvoryLL, IvoryLL Fallback, DmMono, DmMono Fallback, Maxi, Maxi Fallback, Ozik, Ozik Fallback, Planar, Planar Fallback, Raster, Raster Fallback, Honey, Honey Fallback, Beretta, Beretta Fallback, Saans, Saans Fallback, SaansMono, SaansMono Fallback, Serrif, Serrif Fallback, Inter, Inter Fallback, intercom-font

**Shape Personality**: Sharp & Angular — No rounding. Precise, editorial, enterprise feel.

**Full Radius Spectrum**: 0px, 4px, 6px, 8px, 9px, 24px (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~80px internal vertical padding (up to 216px) — **generous**. (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** | `64px` | Top/bottom of full-bleed hero sections |
| **section** | `32px` | Between major bands (color change, content shift) |
| **subsection** | `24px` | Within a section, between content groups |
| **card** | `16px` | Card padding, list-item spacing |
| **compact** | `12px` | Form fields, tight clusters, badge padding |
| **micro** | `8px` | 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).

**7/8 structural patterns detected.**

### Hero Pattern

- **Composition:** split-left-text — Split layout, text-left/media-right — heading + body in left column, image/illustration in right column. Common for product showcases.
- **Viewport coverage:** full-viewport hero (≥70% screen height)
- **Heading:** "The only helpdesk designed for the AI Agent era" — 80px center-aligned
- **Subheading:** "Intercom is the only helpdesk with a natively integrated AI Agent, Fin, meaning every customer conversation improves the next one, enabling perfect ex"
- **Media:** present, positioned right
- **CTAs:** 6 (primary: "Start free trial")
- **Clone instruction:** Reproduce the **split-left-text** layout. Use the heading font-size token at the documented size. Place media right of text.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 42px
- **Logo:** ✓ present
- **Nav links:** 5 primary items
- **CTAs in nav:** 2
- **Clone instruction:** Build a static logo left links left navigation. Reserve 2 slots for primary CTAs.

### Card Grid Pattern

- **Card count:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1419×593px (aspect 2.39:1)
- **Gap:** 0px between cards
- **Content:** ✗ no image
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~2.39:1 aspect ratio. Text/icon-only cards (no photography).

### Pricing Table Pattern

- **Tier count:** 3 pricing tiers
- **Layout:** vertical stacked
- **Columns (desktop):** 3-up
- **Feature list:** ✓ (median ~18 feature points per tier)
- **Clone instruction:** Build a 3-column vertical-stack pricing comparison.

### Testimonial Pattern

- **Count:** 3 testimonial blocks
- **Layout:** list
- **Avg quote length:** 167 chars (medium quote)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
- **Clone instruction:** Build a list of 3 testimonials.   

### CTA Banner Pattern

- **Banner count:** 4
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Start free trial"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.

### Footer Pattern

- **Columns:** 1
- **Links:** 45 total
- **Height:** 522px
- **Includes:** ✗ no newsletter | ✗ no social |  
- **Clone instruction:** Build a 1-column footer with ~45 links per column.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(9, 14, 21, 0.16) 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-out-quad` | `cubic-bezier(.25, .46, .45, .94)` | Custom Ease — Balanced |
| `--ease-out-quart` | `cubic-bezier(.165, .84, .44, 1)` | Custom Ease — Balanced |
| `--wsc-default-transition-timing-function` | `cubic-bezier(.4,0,.2,1)` | Ease Out — Decelerating |
| `--default-transition-timing-function` | `cubic-bezier(.4, 0, .2, 1)` | Ease Out — Decelerating |
| `--ease-out` | `cubic-bezier(0, 0, .2, 1)` | Ease Out — Decelerating |
| `--ease-in-out` | `cubic-bezier(.4, 0, .2, 1)` | Ease Out — Decelerating |
| `--ease-out-cubic` | `cubic-bezier(.215, .61, .355, 1)` | Ease Out — Decelerating |
| `--wsc-ease-out` | `cubic-bezier(0,0,.2,1)` | Ease Out — Decelerating |

### Duration Scale

| CSS Variable | Value | Tier |
|--------------|-------|------|
| `--default-transition-duration` | `.15s` | Fast |
| `--wsc-default-transition-duration` | `.15s` | Fast |

### 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 ui-sans-serif as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-2.4px) at display sizes for compressed, editorial headlines
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use Near-Black (`#111111`) as the primary accent — it's the brand's signature interactive color
- Use 6px border-radius on buttons — the standard corner rounding for interactive elements
- Maintain nav height at 42px — consistent vertical space for the navigation bar
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Build the hero as a split layout with media on the left — text and visual share equal weight
- Include exactly 6 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Repeat the primary CTA across 4 banner sections — conversion paths are layered, not single

### Don't
- 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 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


## 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(17, 17, 17)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(17, 17, 17)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 400px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Desktop | 1140px | Full feature layout |
| Large Desktop | 1300px | Maximum content width |
| Large Desktop | 1450px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `80px` | `40px` |
| heading | line-height | `80px` | `38px` |
| heading | letter-spacing | `-2.4px` | `-1.2px` |
| nav | height | `42px` | `0px` |

### Collapsing Strategy
- Headlines: 80px → 40px 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):

- **Hero collapses split-left-text → split-right-text** — composition shifts (verify on actual mobile render).


## 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.
- **Clip-path shapes** — 8 non-rectangular cut(s).
- **Blend modes** — 1 mix-blend layer(s).
- **CSS-variable animations** (1) — animated custom properties.

> **Motion fingerprint**: Canvas 2D, non-rectangular shapes (10), blend modes

## 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://www.intercom.com/intercom-marketing-site/img/social/default.jpg (1200×630px)
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Hero Image (above-fold dominant visual):**
- Aspect: 1.92:1 (landscape (16:9-ish))
- Rendered size: 1173×611px
- Alt text: "Decorative background image"
- *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.*

**Aspect Ratio Distribution:**
- Landscape (1.15–2.3): 13 (27%)
- Portrait (<0.87): 8 (17%)
- Square (0.87–1.15): 27 (56%)

**Media Format Mix:**
- SVG: 1 (icons, illustrations, decorative geometry)

**Average rendered image size:** 616×471px
**Above-fold image count:** 7 / 48

**Decorative Patterns Detected:**
- 63 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 1 large decorative SVG shape (≥200×200px, non-icon) — likely blob/illustration accents

**Clone instruction for decorative work:** This is a gradient-rich design — invest in multi-stop CSS gradients (3+ color stops), not solid backgrounds.

**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: White (`#ffffff`)
- Primary text: Black (`#000000`)
- Accent: Near-Black (`#111111`)
- Border: Clay (`#d3cec6`)
- Font: ui-sans-serif
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on White background (#ffffff). Headline at 80px ui-sans-serif weight 400, line-height 1, letter-spacing -2.4px, color #000000."
- "Create the primary CTA button: `#111111` background, `#000000` text, 9999px border-radius, 12px 24px padding, 400 weight, ui-sans-serif font."
- "Build navigation: static on `#ffffff`. ui-sans-serif 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to White (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in ui-sans-serif, weight range 300–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Near-Black (`#111111`) is the sole interactive color. On hover → Helpdesk (`#0007cb`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0,0,0.2,1)`. 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 `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (8px–32px). 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:
    - "A complete solution for AI and human agents"
    - "Transparent pricing"
    - "Perfect customer experiences, powered by Intercom"
  sub-headings:
    - "AI-powered agent workspace"
    - "A world-class AI Agent"
    - "Resolve queries faster"
  ctas:
    - "Product"
    - "Customers"
    - "Start free trial"
    - "Fin AI Agent"
    - "View demo"
    - "Fully-featured helpdesk"
    - "AI-powered Insights"
  navigation:
    - "Fin AI Agent"
    - "Customers"
    - "Pricing"
    - "Log in"
    - "Contact sales"
    - "View demo"
    - "Start free trial"
  footer-links:
    - "Intercom 2"
    - "Terms"
```

**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:
  hero:
    count: 7
    avg-ratio: 1.95
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "Decorative background image"
      - "Decorative background image"
      - "Decorative background image"
  product:
    count: 16
    avg-ratio: 1.02
    common-aspect: "~1:1 square"
    sample-alts:
      - "Copilot product UI"
      - "Clouds"
      - "Placeholder"
```

**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">
  Action
</button>
```
_Source pattern detected: padding `8px` · radius `0px` · weight `400`_

**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 · **auth** 1 · **pricing** 4 · **docs** 1 · **blog** 1 · **project** 9 · **social** 1 · **footer** 26 · **other** 11

**Primary actions (conversion path):**
- Account access — "Log in" (login/signup) → `https://app.intercom.com/admins/sign_in`
- Primary call-to-action — "Start free trial" (the conversion path) → `https://app.intercom.com/admins/sign_up?solution_id=29`

**Projects / case studies detected** (clustered by URL + featured image):

*Customers* — medium confidence, 5 items:

| Title | Featured image | Link |
|---|---|---|
| Anthropic | — | https://fin.ai/customers/anthropic |
| Clay | — | https://fin.ai/customers/clay |
| Lightspeed | — | https://fin.ai/customers/lightspeed |
| Rocket Money | — | https://fin.ai/customers/rocket-money |
| Gamma | — | https://fin.ai/customers/gamma |

**Signals:** 2/60 links carry a featured image · dominant link roles: footer-link (33), inline-link (13), content-card (8).

## Extraction Completeness: 72/100 (C)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 18 | 25 | 13 named colors |
| Typography | 20 | 20 | 8 roles defined |
| Components | 4 | 20 | 1 specs extracted |
| Motion & Interaction | 15 | 15 | Keyframes, easing vars |
| CSS Custom Properties | 10 | 10 | 433 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:*

- **Licensed web fonts (MediumLL, IvoryLL, DmMono)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).
- **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 |
|----------|----------------|-------------------|
| **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 | 433 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 8 typography roles inferred |
| §4 Components | Low | 1 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 16 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 48 images, hero present |

### Keyframe Animations (Intercepted from CSS)

**4 @keyframes found** — these are the real animation definitions:

```
@keyframes marquee { ... }
@keyframes marquee-left { ... }
@keyframes marquee-right { ... }
@keyframes onetrust-fade-in { ... }
```

<details><summary>Full keyframes CSS (4 animations)</summary>

```css
@keyframes marquee{0%{transform:translate(0)}
@keyframes marquee-left{0%{transform:translate(0)}
@keyframes marquee-right{0%{transform:translateX(var(--marquee-translate))}
@keyframes onetrust-fade-in{0%{opacity:0}100%{opacity:1}}
```
</details>

### Brand Gradient Palette

**4 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);

/* Gradient 2 */
background: linear-gradient(to right, transparent, black 20%, black 100%);

/* Gradient 3 */
background: linear-gradient(to left, transparent, black 20%, black 100%);

/* Gradient 4 */
background: linear-gradient(to right, transparent 0%, black 20%, black 80%, transparent 100%);

```

### Hover State CSS (Intercepted)

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

```css
@media (hover:hover){.wsc\:group-hover\:block:is(:where(.wsc\:group):hover *){display:block!important}

.wsc\:group-hover\:border-button-hover:is(:where(.wsc\:group):hover *){border-color:var(--wsc-color-button-hover)!important}

.wsc\:group-hover\:bg-button-hover:is(:where(.wsc\:group):hover *){background-color:var(--wsc-color-button-hover)!important}

.wsc\:group-hover\:bg-content-primary:is(:where(.wsc\:group):hover *){background-color:var(--wsc-color-content-primary)!important}

.wsc\:group-hover\:bg-interactive-primary:is(:where(.wsc\:group):hover *){background-color:var(--wsc-color-interactive-primary)!important}

.wsc\:group-hover\:bg-\[length\:0\%_1px\]:is(:where(.wsc\:group):hover *){background-size:0% 1px!important}

.wsc\:group-hover\:bg-\[position\:100\%_100\%\]:is(:where(.wsc\:group):hover *){background-position:100% 100%!important}

.wsc\:group-hover\:text-interactive-control:is(:where(.wsc\:group):hover *){color:var(--wsc-color-interactive-control)!important}

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 1344 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**15 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
`400px` · `425px` · `426px` · `530px` · `550px` · `600px` · `640px` · `768px` · `896px` · `1140px` · `1200px` · `1300px` · `1370px` · `1400px` … (+1 more)

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×855 · `14px`×329 · `12px`×27 · `20px`×26 · `28px`×24 · `54px`×21 · `40px`×17 · `24px`×16

**Radius scale** (× = paint count): `4px`×20 · `6px`×13 · `50%`×3 · `9px`×2 · `16.7%`×2 · `24px`×1 · `20px`×1

**Weights** (× = paint count): `400`×1235 · `300`×85 · `500`×18 · `700`×2

**Layout gaps** (× = paint count): `normal 16px`×16 · `4px`×11 · `24px`×10 · `12px`×10 · `8px`×9 · `16px`×5 · `normal 8px`×5 · `10px`×4

**Elevation (real shadows)**:
```css
rgba(9, 14, 21, 0.16) 0px 5px 40px 0px
rgba(9, 14, 21, 0.06) 0px 4px 28px 0px, rgba(9, 14, 21, 0.06) 0px 1px 4px 0px
rgba(9, 14, 21, 0.16) 0px 0px 4px 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
header { background-color:var(--wsc-color-background-screen)!important }
header { color:var(--wsc-color-content-primary)!important }
h1 { font-size:var(--text-heading-2-mobile); font-weight:var(--tw-font-weight,var(--text-heading-2-mobile--font-weight)) }
@media (min-width: 48rem) h1 { font-size:var(--text-heading-2-tablet); font-weight:var(--tw-font-weight,var(--text-heading-2-tablet--font-weight)) }
@media (min-width: 80rem) h1 { font-size:var(--text-heading-2-desktop); font-weight:var(--tw-font-weight,var(--text-heading-2-desktop--font-weight)) }
h2 { font-size:var(--text-heading-3-mobile); font-weight:var(--tw-font-weight,var(--text-heading-3-mobile--font-weight)) }
@media (min-width: 48rem) h2 { font-size:var(--text-heading-3-tablet); font-weight:var(--tw-font-weight,var(--text-heading-3-tablet--font-weight)) }
@media (min-width: 80rem) h2 { font-size:var(--text-heading-3-desktop); font-weight:var(--tw-font-weight,var(--text-heading-3-desktop--font-weight)) }
```

> 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.
