narrative: |
  attio.com is built on a mid-dark canvas (lab(99.9987 0.0337958 0.000309944)).
  The system uses rgb(38, 109, 240) as the high-saturation accent for primary actions.
  Moderately rounded CTAs (12px) — modern SaaS standard, neither sharp nor pill alongside inter as the primary typeface.
  Inter is paired with inter Fallback for secondary roles.
  A layered elevation system (6 distinct shadows) building a clear front-to-back hierarchy.
  Motion is a first-class concern — 50 keyframe animations plus transition-driven interactions.

# Design System — attio.com
> Extracted automatically by Clone Architect from https://attio.com
> Date: 2026-05-30
> 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).

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `lab(99.9987 0.0337958 0.000309944)` is the page background. Every component composits against this.
> - **Accent**: `rgb(38, 109, 240)` 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

attio.com sits on a unknown canvas (`#000000`), a neutral foundation calibrated for sustained reading and component contrast. 

Headlines are set in **interDisplay**, a sans-serif display face (the dominant type signature, e.g. "The next era of revenue" at 40px). Body text is set in **inter**, deployed with OpenType features enabled globally (`"ss03"`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. Headlines use weight 600 for confident, assertive presence — the brand wants to be heard. Negative letter-spacing at display sizes (-1.28px at 64px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Unknown (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Royal Blue** (`#266df0`) 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 — each level combines several blurred layers at varying offsets to simulate how light falls on stacked surfaces. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Unknown (`#000000`)
- Primary typeface: JetBrains Mono
- Primary text: Unknown (`#000000`)
- Accent: Royal Blue (`#266df0`)
- Display: 64px weight 600, letter-spacing -1.28px
- Shadow system: 6 distinct elevation levels
- Custom fonts loaded: JetBrains Mono, JetBrains Mono Fallback, inter, inter Fallback, interDisplay, interDisplay Fallback, tiemposText, tiemposText Fallback

### Font Weight Scale

CSS custom properties define 15 explicit weight steps:
- `--font-weight-normal`: `400` — Regular
- `--text-sm--font-weight`: `500` — Medium
- `--text-2xl--font-weight`: `500` — Medium
- `--text-xl--font-weight`: `500` — Medium
- `--text-xs--font-weight`: `500` — Medium
- `--text-base--font-weight`: `500` — Medium
- `--text-lg--font-weight`: `500` — Medium
- `--font-weight-medium`: `500` — Medium
- `--text-heading-sm--font-weight`: `600` — SemiBold
- `--text-heading-lg--font-weight`: `600` — SemiBold
- `--text-heading-md--font-weight`: `600` — SemiBold
- `--text-heading-xl--font-weight`: `600` — SemiBold
- `--font-weight-semibold`: `600` — SemiBold
- `--text-heading-xs--font-weight`: `600` — SemiBold
- `--font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `64px`, `56px`, `32px`, `20px`, `16px`, `15px`, `14px`, `13px`, `12px`, `11.30px`, `11px`, `10px`

> 6 size(s) detected outside the sampled hierarchy (56px, 20px, 13px, 11.3px, 11px, 10px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

### OpenType & Variable Font Features

The typography uses these OpenType features intentionally — this is a sophisticated type system, not a default fallback:

- **stylistic sets** (`ss0X`) — alternate letterforms enabled (often for brand-specific glyph variants)
- **contextual alternates** (`calt`) — connections between letters refined contextually

**Clone instruction:** Enable these in your CSS:
```css
body {
  font-feature-settings: "ss03", "calt";
}
```

**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: `Ghost`, `Outline`
- **DO NOT introduce new buttons variants** without justification

### Inputs & Forms
- **1 shape(s)** in this system: `Text Input`
- **DO NOT introduce new inputs & forms 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 | 6px |
| sm | 10px |
| md | 13px |
| 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 | 13px | Cards, containers |
| Lg | 16px | Large rounded elements, pill segments |
| Xl | 16px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `10px` |
| Inputs & Forms | `10px` |
| Page Body | `0px` |
| Navigation | `0px` |
| Primary Input | `10px` |

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

**Full Radius Spectrum**: 4px, 5px, 6px, 7px, 8px, 9px, 10px, 11px (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** | `13px` | Card padding, list-item spacing |
| **compact** | `10px` | Form fields, tight clusters, badge padding |
| **micro** | `6px` | 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:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages.
- **Viewport coverage:** full-viewport hero (≥70% screen height)
- **Heading:** "The revenue platform engineered for scale." — 64px center-aligned
- **Subheading:** "Attio is the AI CRM that builds pipeline, accelerates every deal, and compounds revenue around the clock."
- **Media:** present, positioned top
- **CTAs:** 6 (primary: "Start for free")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. Place media top of text.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 67px
- **Logo:** ✓ present

> This design moves with deliberate & calm timing using custom cubic-bezier curves, creating a UI that feels calm and controlled.

## 8. Do's and Don'ts

### Do
- Use inter as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-1.28px) at display sizes for compressed, editorial headlines
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use Royal Blue (`#266df0`) as the primary accent — it's the brand's signature interactive color
- Use 12px border-radius on buttons — the standard corner rounding for interactive elements
- Style form inputs with a `1px solid lab(86.0989 -0.77799 -4.0961)` border — use border-based inputs, not floating labels or underline-only
- Maintain nav height at 67px — 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
- Include exactly 6 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose

### 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 remove the input border — the border is the primary affordance indicator for form fields
- 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 `lab(99.9987 0.0337958 0.000309944)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'lab(99.9987 0.0337958 0.000309944)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(38, 109, 240)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(38, 109, 240)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 600px | Expanded mobile layout |
| Tablet | 992px | Multi-column grids begin |
| Desktop | 1199px | Full feature layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `64px` | `40px` |
| heading | line-height | `64px` | `44px` |
| heading | letter-spacing | `-1.28px` | `-0.4px` |
| nav | padding | `16px 0px 15px` | `8px 0px 7px` |
| nav | height | `67px` | `51px` |
| card | width | `1390px` | `390px` |

### Collapsing Strategy
- Headlines: 64px → 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):

- **Nav CTAs reduced** on mobile (4 → 0) — the design prioritizes content over conversion buttons at small sizes.

## 9b. Visual Tone & Photography

**Tone:** Illustration-driven

The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand.

**Canonical Brand Image (OG):**
- https://a.storyblok.com/f/234930/1200x630/df480627b4/attio-og-image.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): 0 (0%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 3 (33%)
- Ultra-wide (>2.3): 6 (67%)

**Media Format Mix:**
- SVG: 20 (icons, illustrations, decorative geometry)

**Average rendered image size:** 173×108px
**Above-fold image count:** 0 / 9

**Decorative Patterns Detected:**
- 30 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 3 radial gradients — circular color blooms used for spotlight/glow effects
- 14 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic

**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:**
- Use vector illustration as the primary visual language — photos will read as off-brand.
- Maintain consistent illustration style (line weight, color palette) across the site.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Unknown (`#000000`)
- Primary text: Unknown (`#000000`)
- Accent: Royal Blue (`#266df0`)
- Border: Silver (`#cad0d9`)
- Font: inter
- Body: 16px weight 500

### Example Component Prompts
- "Create a hero section on Unknown background (#000000). Headline at 64px inter weight 600, line-height 1, letter-spacing -1.28px, color #000000."
- "Create the primary CTA button: `#266df0` background, `#000000` text, 10px border-radius, 12px 24px padding, 500 weight, inter font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#000000`. inter 16px weight 500 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Unknown (`#000000`) — every component is composited against this exact base.
2. **Typography**: All type in inter, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Royal Blue (`#266df0`) is the sole interactive color. On hover → #9162f9 (`#9162f9`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Timing: 150ms for micro-interactions, 250ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `12px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (6px–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:
    - "[01]
POWERFUL PLATFORM"
    - "Start with 14 days
of Pro, for free."
    - "Enterprise-ready, out of the box."
    - "The next era of revenue
runs on Attio."
    - "Platform"
  sub-headings:
    - "The intelligent system that never sleeps."
    - "Revenue agents at your command."
    - "The only CRM with Universal Context
™
."
  ctas:
    - "Platform"
    - "Customers"
    - "Sign in"
    - "Start for free"
    - "Ask Attio"
    - "Data model"
    - "Explore agents"
    - "Scale-ups"
  navigation:
    - "Customers"
    - "Pricing"
    - "Ask AttioSearch and create with AI"
    - "AINative to your CRM"
    - "Data modelSync and enrich your data"
    - "AgentsAt your call"
    - "WorkflowsAutomate any process"
    - "SequencesPersonalized outreach"
    - "ReportingInsights in real time"
    - "Attio 101"
  footer-links:
    - "Refer a team
New"
    - "Services Agreement"
```

**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: 5
    avg-ratio: 2.88
    common-aspect: "~16:6 banner"
  thumbnail:
    count: 17
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Basepoint"
```

**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 4px` · radius `12px` · weight `500`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `0px` · radius `0px` · shadow `none`_

**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.

## Extraction Completeness: 76/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 25 | 25 | 21 named colors |
| Typography | 15 | 20 | 6 roles defined |
| Components | 8 | 20 | 2 specs extracted |
| Motion & Interaction | 15 | 15 | Keyframes present, easing vars |
| CSS Custom Properties | 10 | 10 | 336 vars |
| Responsive Breakpoints | 3 | 5 | 3 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.

| 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 |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 336 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 6 typography roles inferred |
| §4 Components | Low | 2 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 | 3 breakpoints detected |
| §9b Photography | Medium | 9 images, hero not detected |
