narrative: |
  bugatti.com is built on a near-black canvas (rgb(0, 0, 0)).
  The system uses rgb(0, 75, 250) as the high-saturation accent for primary actions.
  Ui-sans-serif as the primary typeface.

# Design System — bugatti.com
> Extracted automatically by Clone Architect from https://bugatti.com
> Date: 2026-05-30
> Viewport: Desktop 1440x900 + Mobile 390x844
> Every value in this file comes from real getComputedStyle() — no approximation.

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(0, 0, 0)` is the page background. Every component composits against this.
> - **Accent**: `rgb(0, 75, 250)` 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**: 6px 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

bugatti.com commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a near-pure-black surface (`#000000`) 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 **ui-sans-serif**. Headlines run at a remarkably light weight (0) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. 

Body text reads in Pure Black (`#000000`) — slightly under-bright, preventing eye strain on the dark surface. **#004bfa** (`#004bfa`) 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 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: Pure Black (`#000000`)
- Primary typeface: Bugatti Text Bold
- Primary text: Light Gray (`#e2e8f0`)
- Accent: #004bfa (`#004bfa`)
- Shadow system: 1 distinct elevation levels
- Custom fonts loaded: Bugatti Text Bold, Bugatti Text Regular, Bugatti Display, Bugatti Monospace

## 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(255, 255, 255)"
    hover:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
  link:
    default:
      bg: "rgba(0, 0, 0, 0.8)"
      fg: "rgb(255, 255, 255)"
      border: "1px solid rgba(255, 255, 255, 0.2)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
```

**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: `Ghost`, `Subtle`, `Pill`, `Outline`, `Ghost`
- **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 | 12px |
| sm | 24px |
| md | 36px |
| base | 48px |
| 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 | 6px | Buttons, inputs, small elements |
| Md | 6px | Cards, containers |
| Lg | 6px | Large rounded elements, pill segments |
| Xl | 6px | 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**: 4px, 6px, full/pill (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** | `36px` | Card padding, list-item spacing |
| **compact** | `24px` | Form fields, tight clusters, badge padding |
| **micro** | `12px` | 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).

**3/8 structural patterns detected.**

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** logo-center-links-split — Logo centered, links split on either side
- **Height:** 104px
- **Logo:** ✓ present
- **Nav links:** 2 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static logo center links split navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 6 cards detected
- **Columns (desktop):** 3-up grid
- **Card dimensions:** 494×618px (aspect 0.8:1)
- **Gap:** 36px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 3-column grid (desktop) with cards at ~0.8:1 aspect ratio. Each card has an image at the top.

### Footer Pattern

- **Columns:** 1
- **Links:** 46 total
- **Height:** 963px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~46 links per column, social media links, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0.1) 0px 10px 15px -3px`,<br>`rgba(0, 0, 0, 0.1) 0px 4px 6px -4px` | 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

### Dominant Easing Curves

| Curve | Semantic Name |
|-------|---------------|
| `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced |
| `cubic-bezier(0,0,0.2,1)` | Material Decelerate — Entrance |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `150ms` | Fast | Hover states, micro-interactions |
| `300ms` | Normal | Panel open/close, navigation |
| `700ms` | Cinematic | Splash, marketing reveals |

### Copy-Paste Transition Snippets

**Color / Background**
```css
transition: color 0.3s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.3s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.3s cubic-...;
```

**All Props**
```css
transition: 0.7s cubic-bezier(0, 0, 0.2, 1);
```

**Transform**
```css
transition: transform 0.3s cubic-bezier(0.4, 0, 0.2, 1);
```

**All Props**
```css
transition: 0.3s cubic-bezier(0.4, 0, 0.2, 1);
```

### Keyframe Animation Catalog

| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `ping` | Fade + Move | transform, opacity | Attention / status |
| `spin` | Rotate / Spin | transform | Loading indicator |
| `marquee-left` | Slide | transform | UI transition |
| `marquee-up` | Slide | transform | UI transition |
| `appear` | Fade | left, opacity | UI transition |
| `disappear` | Fade | left, opacity | UI transition |

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 6 unique animations (6 total including variants)

> 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 dark background (`#000000`) as the foundation — this is a dark-mode-native design
- Use ui-sans-serif as the primary typeface — it defines the brand personality
- Keep font weights between 400-400 — the system uses a narrow weight range for subtle hierarchy
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
- Use #004bfa (`#004bfa`) 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 104px — consistent vertical space for the navigation bar
- Each card includes a top image — imagery is part of the card identity, not optional
- Use a 3-column grid on desktop — density matters for this content type

### 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 use weight 700 (bold) or above — 400 is the maximum weight in this system
- Don't invent new shadow values — use only the extracted shadow levels
- Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
- 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
- Don't put a CTA button in the nav — this design uses links only at the top


## 7b. Enforceable Brand Rules

*Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.*

```yaml
rules:
  - id: brand-canvas-001
    type: do
    rule: "Always use the page background `rgb(0, 0, 0)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(0, 0, 0)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(0, 75, 250)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(0, 75, 250)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1280px | Full feature layout |
| Large Desktop | 1536px | Maximum content width |
| Ultra-wide | 1720px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | padding | `36px 48px` | `20px 12px` |
| nav | height | `104px` | `72px` |
| sidebar | width | `1440px` | `390px` |

### Collapsing Strategy
- 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):

- **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.

## 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://bugatti.imgix.net/677abba7531541bbadaa35a0/landingpage-og.jpg
  *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: 1.78:1 (landscape (16:9-ish))
- Rendered size: 466×262px
- Alt text: "a group of cars are parked in front of a castle"
- *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): 3 (17%)
- Portrait (<0.87): 6 (33%)
- Square (0.87–1.15): 1 (6%)
- Ultra-wide (>2.3): 8 (44%)

**Media Format Mix:**
- JPG: 10 (typically photographic content)
- PNG: 6 (logos, transparent UI elements, mockups)
- SVG: 3 (icons, illustrations, decorative geometry)

**Average rendered image size:** 549×372px
**Above-fold image count:** 1 / 18

**Decorative Patterns Detected:**
- 10 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
- **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:**
- 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: Pure Black (`#000000`)
- Primary text: Pure Black (`#000000`)
- Accent: #004bfa (`#004bfa`)
- Border: Translucent Pure White (8%) (`rgba(255, 255, 255, 0.08)`)
- Font: ui-sans-serif
- Body: 16px weight 400

### Example Component Prompts
- "Create the primary CTA button: `#004bfa` background, `#ffffff` text, 9999px border-radius, 9px 18px padding, 400 weight, ui-sans-serif font."
- "Build navigation: absolute on `#000000`. ui-sans-serif 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Pure Black (`#000000`) — every component is composited against this exact base.
2. **Typography**: All type in ui-sans-serif, weight range 400–400. Never exceed 400 — heavier weights break the brand's tonal restraint.
3. **Accent**: #004bfa (`#004bfa`) is the sole interactive color. On hover → #004bfa (`#004bfa`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `6px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (12px–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.

## 11. CSS Design Tokens Raw Export

*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

```css
/* Colors */
:root {
  --ca-surface-2: #3f3f3f;
  --ca-ink-muted: #e2e8f0;
  --ca-hairline: #ffffff;
  --ca-primary-hover: #004bfa;
}

/* Typography */
:root {
  --ca-font-primary: "Bugatti Display", system-ui, sans-serif;
  --ca-text-display: 60px;
  --ca-text-heading: 36px;
  --ca-text-body: 16px;
  --ca-text-small: 16px;
  --ca-text-button: 14px;
}

/* Spacing & Radius */
:root {
  --ca-space-xxs: 2px;
  --ca-space-xs: 12px;
  --ca-space-sm: 24px;
  --ca-space-md: 36px;
  --ca-space-base: 48px;
  --ca-space-lg: 24px;
  --ca-space-xl: 32px;
  --ca-space-2xl: 48px;
  --ca-space-3xl: 64px;
  --ca-radius-none: 0px;
  --ca-radius-xs: 4px;
  --ca-radius-sm: 6px;
  --ca-radius-md: 6px;
  --ca-radius-lg: 6px;
  --ca-radius-xl: 6px;
  --ca-radius-full: 9999px;
}
```


## 13. Page Structure Skeleton

*The actual layout the source site uses. Reproduce these sections in order to match the site structure.*

```yaml
page-skeleton:
  - section: navigation
    tag: nav
    classes: ["absolute", "inset-x-0", "top-0", "z-50"]
    height: 104px
    width: full-bleed
    layout: flex-row justify=space-between
    children: 3
    padding: "36px 48px"
  - section: main-content
    tag: main
    classes: ["w-full"]
    height: 5895px
    width: full-bleed
    layout: block
    children: 8
  - section: footer
    tag: footer
    classes: ["bg-grey-dark/30"]
    height: 963px
    width: full-bleed
    layout: block
    children: 2
    bg: "rgba(63, 63, 63, 0.3)"
```

**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:
    - "TIMELESS ELEGANCE AND SPEED"
  sub-headings:
    - "THE BUGATTI F.K.P. HOMMAGE"
    - "Discover BUGATTI"
    - "HERITAGE, CRAFTSMANSHIP AND INNOVATION"
  ctas:
    - "CLOSE"
    - "EXPLORE OUR OPPORTUNITIES"
    - "MENU"
    - "WITNESS THE LEGEND"
    - "LEARN MORE"
  navigation:
    - "BUGATTI Logo"
    - "STORE"
  footer-links:
    - "TOURBILLON"
    - "English"
    - "LinkedIn"
```

**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: 1
    avg-ratio: 5.35
    common-aspect: "~16:6 banner"
    sample-alts:
      - "If comparable it is no longer Bugatti.svg"
  product:
    count: 1
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "a person wearing gloves is painting a bugatti logo"
  thumbnail:
    count: 1
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "a man in a white shirt is working on a blue and black car"
```

**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">
  CLOSE
Are you ready for a new adventure?

We are hiring.

EXPLORE OUR OPPORTUNITIES
</button>
```
_Source pattern detected: padding `12px` · radius `6px` · 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.

## Extraction Completeness: 51/100 (D)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 7 | 25 | 5 named colors |
| Typography | 15 | 20 | 6 roles defined |
| Components | 8 | 20 | 2 specs extracted |
| Motion & Interaction | 12 | 15 | Keyframes present |
| CSS Custom Properties | 4 | 10 | 78 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.

| Category | What's missing | Fallback strategy |
|----------|----------------|-------------------|
| **Dark mode** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants unless explicitly requested |
| **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 | 78 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 | 19 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 18 images, hero present |
