narrative: |
  intercom.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses #37b54a as the accent for primary actions and brand signals.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside ui-sans-serif as the primary typeface.

> **🤖 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**: `#37b54a` 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 adopts the classic pure-white canvas (`#ffffff`) — a deliberate choice that recedes into transparency, letting typography, color and product imagery carry the entire visual weight. 

Typography is anchored in **ui-sans-serif**. Headlines run at a remarkably light weight (400) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. 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 100.0:1, well above WCAG AA). **Success Green** (`#37b54a`) provides interactive distinction without visual aggression. Elevation is built from multi-layer shadow stacks — each level combines several blurred layers at varying offsets to simulate the way light actually falls on stacked surfaces, not the simulated drop-shadow of cheap interfaces. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: White (`#ffffff`)
- Primary typeface: MediumLL
- Accent: Success Green (`#37b54a`)
- 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

## 4b. 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(0, 0, 0)"
    focus:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
```

**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
- **7 shape(s)** in this system: `Icon Button`, `Ghost`, `Ghost`, `Outline`, `Outline`
- **DO NOT introduce new buttons variants** without justification

### Navigation
- **1 shape(s)** in this system: `Main Nav`
- **DO NOT introduce new navigation variants** without justification

## 5. Layout Principles

### Layout Type
**top-nav + content**

### Grid
Single column, centered content

### Max Width
1200px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 8px |
| sm | 24px |
| md | 12px |
| base | 16px |
| lg | 24px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 4px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 9px | Cards, containers |
| Lg | 24px | Large rounded elements, pill segments |
| Xl | 24px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Navigation | `none` |
| Page Body | `0px` |

**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

*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** | `12px` | Card padding, list-item spacing |
| **compact** | `24px` | 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-right-text — Split layout, media-left/text-right — image in left column, heading + body in right column. Less common variant.
- **Viewport coverage:** full-viewport hero (≥70% screen height)
- **Heading:** "The only helpdesk designed for the AI Agent era" — 80px left-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 left
- **CTAs:** 6 (primary: "Start free trial")
- **Clone instruction:** Reproduce the **split-right-text** layout. Use the heading font-size token at the documented size. Place media left 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 |

| `--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 Success Green (`#37b54a`) 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 right — 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 `#37b54a` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#37b54a\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 400px | Single column, compact spacing |
| Mobile Large | 530px | Expanded mobile layout |
| Mobile Large | 600px | Expanded mobile layout |
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 896px | Multi-column grids begin |
| Tablet | 1024px | Multi-column grids begin |

### 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: 8px 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):

*No major structural differences detected between desktop and mobile widgets. The same blueprints scale rather than collapse — verify by inspecting actual mobile render.*

## 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): 14 (26%)
- Portrait (<0.87): 12 (23%)
- Square (0.87–1.15): 27 (51%)

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

**Average rendered image size:** 571×442px
**Above-fold image count:** 12 / 53

**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: Success Green (`#37b54a`)
- 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: `#37b54a` background, `#000000` text, 9999px border-radius, 8px 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**: Success Green (`#37b54a`) is the sole interactive color. On hover → #5de071 (`#5de071`). 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"
    - "Natively integrated AI Agent"
  navigation:
    - "Fin"
    - "Log in"
    - "Contact sales"
    - "View demo"
    - "Start free trial"
    - "Customers"
    - "Pricing"
    - "Fin AI Agent"
  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:
  logo:
    count: 1
    avg-ratio: 1.51
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "Sunset sky with birds in flight"
  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: 17
    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.


## 12. Known Extraction Gaps

*Auto-detected limitations of this extraction — 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.
