description: "Light product system built on #fbfbf8 with #ff5229 as the primary CTA accent. Type anchored in Inter at 16px / weight 400. Extracted automatically from https://mistral.ai/ — every value from getComputedStyle(), no approximation."
narrative: |
  mistral.ai is built on a warm, off-white canvas (rgb(251, 251, 248)).
  The system uses #ff5229 as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Inter as the primary typeface.

# Design System — mistral.ai
> Extracted automatically by Clone Architect from https://mistral.ai
> 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(251, 251, 248)` is the page background. Every component composits against this.
> - **Accent**: `#ff5229` 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

mistral.ai's canvas is a warm, intentionally-tinted surface (`#fbfbf8`) — a refusal of the default white that immediately signals editorial intent. This isn't sterility, it's an invitation to read. 

Typography is anchored in **Inter**. Headlines run at a remarkably light weight (400) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. 

Body text reads in Black (`#000000`) (contrast ratio 98.3:1, well above WCAG AA). **Vermillion** (`#ff5229`) 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: Cream (`#fbfbf8`)
- Primary typeface: ALTMistral
- Accent: Vermillion (`#ff5229`)
- Shadow system: 1 distinct elevation levels
- Custom fonts loaded: ALTMistral, Space Mono, Inter, Source Sans 3

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Link**:
  - **hover:** bg transparent → #fbfbf8

*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)"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
    hover:
      bg: "rgb(251, 251, 248)"
      fg: "rgb(0, 0, 0)"
  card:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 0)"
  navLink:
    default:
      bg: "rgb(251, 251, 248)"
      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
- **3 shape(s)** in this system: `Ghost`, `Ghost`, `Subtle`
- **DO NOT introduce new buttons variants** without justification

### Cards & Containers
- **1 shape(s)** in this system: `Standard Card`
- **DO NOT introduce new cards & containers variants** without justification

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

### CTA Banners
- **1 shape(s)** in this system: `Full-width CTA`
- **DO NOT introduce new cta banners 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 | 16px |
| 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 | 12px | Cards, containers |
| Lg | 12px | Large rounded elements, pill segments |
| Xl | 32px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `0px` |
| Navigation | `none` |
| CTA Banners | `0px` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 0px, 4px, 6px, 8px, 12px, 32px (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** | `16px` | 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).

**3/8 structural patterns detected.**

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 48px
- **Logo:** ✗ absent
- **Nav links:** 4 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:** 8 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1439×851px (aspect 1.69:1)
- **Gap:** 0px between cards
- **Content:** ✗ no image + icon + CTA
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.69:1 aspect ratio. Text/icon-only cards (no photography).

### Footer Pattern

- **Columns:** 1
- **Links:** 1 total
- **Height:** 52px
- **Includes:** ✗ no newsletter | ✗ no social |  
- **Clone instruction:** Build a 1-column footer with ~1 links per column.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(21, 21, 31, 0.02) 0px 4px 8px 0px`,<br>`rgba(21, 21, 31, 0.02) 0px 2px 4px 0px`,<br>`rgba(21, 21, 31, 0.02) 0px 1px 2px 0px`,<br>`rgba(21, 21, 31, 0.02) 0px 0px 1px 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-out` | `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 |

### Duration Scale

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

### Copy-Paste Transition Snippets

**Color / Background**
```css
transition: color 0.15s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.15s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.15s cub...;
```

**All Props**

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `150ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 17 unique animations (20 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 Cream (`#fbfbf8`) as the page background — it's intentionally not pure white
- Use Inter as the primary typeface — it defines the brand personality
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use Surface Brand (`#ff5229`) 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
- Apply 8px padding inside cards — matches the design system's content breathing room
- Maintain nav height at 48px — consistent vertical space for the navigation bar
- Each card uses an icon (not photo) — the visual language is illustrative, not photographic

### Don't
- Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- 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
- Don't put a CTA button in the nav — this design uses links only at the top
- Don't over-build the footer — this design keeps it minimal (1 cols, 1 links)


## 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(251, 251, 248)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(251, 251, 248)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `#ff5229` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#ff5229\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Tablet | 768px | Multi-column grids begin |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | height | `48px` | `100%` |
| card | width | `100%` | `251px` |

### 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):

*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:** 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://mistral.ai/cms-media/api/media/file/OG-Main-1.jpg (2400×1350px)
  *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: 1:1 (square / portrait)
- Rendered size: 64×64px
- *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): 22 (45%)
- Portrait (<0.87): 12 (24%)
- Square (0.87–1.15): 15 (31%)

**Media Format Mix:**
- WebP: 48 (optimized photo/illustration hybrid)
- SVG: 2 (icons, illustrations, decorative geometry)

**Average rendered image size:** 335×194px
**Above-fold image count:** 3 / 49

**Decorative Patterns Detected:**
- 1 large decorative SVG shape (≥200×200px, non-icon) — likely blob/illustration accents

**Clone instruction for decorative work:** Decorative details are subtle — don't over-style; the design relies on restraint.

**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: Cream (`#fbfbf8`)
- Primary text: Black (`#000000`)
- Accent: Vermillion (`#ff5229`)
- Border: Light Gray (`#e4e3de`)
- Font: Inter
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Cream background (#fbfbf8). Headline at 16px Inter weight 400, line-height 1.5, color #000000."
- "Create the primary CTA button: `#ff5229` background, `#000000` text, 9999px border-radius, 12px 24px padding, 500 weight, Inter font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 8px."
- "Build navigation: static on `#fbfbf8`. Inter 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Cream (`#fbfbf8`) — 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**: Vermillion (`#ff5229`) is the sole interactive color. On hover → M Tricolor Red (`#e51300`). 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, 150ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `0px`, cards 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.

## 11. CSS Design Tokens Raw Export

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

```css
/* Colors */
:root {
  --ca-background: #fbfbf8;

## 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: main-content
    tag: main
    height: 10935px
    width: full-bleed
    layout: block
    children: 1

    padding: "8px"
  - section: section-5
    tag: section
    classes: ["py-4", "flex", "flex-col", "items-center"]
    height: 316px
    width: 1360px
    layout: flex-column justify=center
    children: 1

    children: 2
```

**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:
  sub-headings:
    - "Products"
  ctas:
    - "Products"
    - "Contact sales"
    - "Start building"
    - "Studio

Build, test, and run AI agents and apps."
    - "Delivery methodology"
    - "Introducing Search Toolkit"
  navigation:
    - "Start building"
    - "Contact sales"
    - "Vibe

AI agent for long-horizon work."
    - "Plans"
    - "API pricing"
    - "For enterprises"
    - "Delivery methodology"
    - "Model customization"
    - "Financial services"
    - "Public sector & government"
  footer-links:
    - "Read all news"
    - "Vibe"
```

**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: 13
    avg-ratio: 2.66
    common-aspect: "~16:6 banner"
    sample-alts:
      - "IBM"
      - "ASML (black)"
      - "Cisco logo"
  thumbnail:
    count: 21
    avg-ratio: 1.01
    common-aspect: "~1:1 square"
```

**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 `0px` · radius `0px` · weight `400`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `40px` · 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:*

- **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.
- **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: 75/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 25 | 25 | 19 named colors |
| Typography | 8 | 20 | 3 roles defined |
| Components | 16 | 20 | 4 specs extracted |
| Motion & Interaction | 15 | 15 | Keyframes present, easing vars |
| CSS Custom Properties | 10 | 10 | 228 vars |
| Responsive Breakpoints | 1 | 5 | 1 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 | 228 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | Medium | 3 typography roles inferred |
| §4 Components | Medium | 4 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 | Medium | 1 breakpoints detected |
| §9b Photography | High | 49 images, hero present |
