narrative: |
  hashicorp.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses #ffe543 as the high-saturation accent for primary actions.
  Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside system-ui 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**: `#ffe543` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 88px between major bands. Card padding: 56px.
> - **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

hashicorp.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 **dejavu-sans-mono-web** with OpenType utility features (`"kern"`) for data-dense contexts. Headlines use weight 600 for confident, assertive presence — the brand wants to be heard. 

Body text reads in Brand Logomark (`#000000`) (contrast ratio 100.0:1, well above WCAG AA). **#ffe543** (`#ffe543`) 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: Pure White (`#ffffff`)
- Primary typeface: dejavu-sans-mono-web
- Accent: #ffe543 (`#ffe543`)
- Display: 82px weight 600
- Shadow system: 7 distinct elevation levels
- Custom fonts loaded: dejavu-sans-mono-web, WistiaPlayerInterNumbersSemiBold, WistiaPlayerInter

|------|------|------|--------|-------------|----------------|-------|
| Display Hero | dejavu-sans-mono-web | 82px | 600 | 1.17 | normal | Main headline (h1) |

| Button | dejavu-sans-mono-web | 15.008px | 500 | 1.6 | normal | Button label (15.008px) |
| Link | dejavu-sans-mono-web | 14px | 500 | 1.29 | normal | Link (14px) — Decoration: none |

| Caption / Badge | dejavu-sans-mono-web | 13px | 500 | 1.69 | 1.3px | uppercase, small text (13px) |

### Font Weight Scale

CSS custom properties define 5 explicit weight steps:
- `--mds-typography-font-weight-light`: `300` — Light
- `--mds-typography-font-weight-regular`: `400` — Regular
- `--mds-typography-font-weight-medium`: `500` — Medium
- `--mds-typography-font-weight-semibold`: `600` — SemiBold
- `--mds-typography-font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `82px`, `52px`, `34px`, `20px`, `19px`, `16px`, `15.01px`, `15px`, `14px`, `13.33px`, `13px`, `12.35px`

> 6 size(s) detected outside the sampled hierarchy (52px, 34px, 20px, 19px, 15px, 12.35px). 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:

- **tabular figures** (`tnum`) — numbers align vertically, essential for pricing tables and dashboards

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

## 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`, `Light / Invert`, `Light / Invert`, `Primary Brand`, `Light / Invert`
- **DO NOT introduce new buttons variants** without justification

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
1200px

### Spacing System
Generous spacing — editorial breathing room

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 6px |
| sm | 8px |
| md | 12px |
| base | 24px |
| lg | 56px |
| xl | 64px |
| 2xl | 88px |
| 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 | 8px | Cards, containers |
| Lg | 8px | Large rounded elements, pill segments |
| Xl | 8px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `6px` |
| Inputs & Forms | `5px` |
| Navigation | `none` |
| CTA Banners | `0px` |
| Page Body | `0px` |
| Primary Input | `5px` |

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

**Full Radius Spectrum**: 0px, 2px, 3px, 4px, 5px, 6px, 8px, 60px (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** | `64px` | Between major bands (color change, content shift) |
| **subsection** | `56px` | Within a section, between content groups |
| **card** | `12px` | Card padding, list-item spacing |
| **compact** | `8px` | 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).

**4/8 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:** "L'infrastructure permet l'innovation" — 82px center-aligned
- **Media:** present, positioned top
- **CTAs:** 1 (primary: "Nous contacter")
- **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:** 64px
- **Logo:** ✓ present
- **Nav links:** 0 primary items
- **CTAs in nav:** 4
- **Clone instruction:** Build a static unknown navigation. Reserve 4 slots for primary CTAs.

### Card Grid Pattern

- **Card count:** 6 cards detected
- **Columns (desktop):** 4-up grid
- **Card dimensions:** 383×581px (aspect 0.66:1)
- **Gap:** 32px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 4-column grid (desktop) with cards at ~0.66:1 aspect ratio. Each card has an image at the top.

### Footer Pattern

- **Columns:** 1
- **Links:** 22 total
- **Height:** 1047px
- **Includes:** ✓ newsletter signup | ✓ social icons |  
- **Clone instruction:** Build a 1-column footer with ~22 links per column, newsletter signup, social media links.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgb(89, 144, 255) 0px 0px 0px 3px`,<br>`rgba(101, 106, 118, 0.05) 0px 1px 1px 0px`,<br>`rgba(101, 106, 118, 0.05) 0px 2px 2px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(101, 106, 118, 0.05) 0px 1px 1px 0px`,<br>`rgba(101, 106, 118, 0.05) 0px 2px 2px 0px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgba(97, 104, 117, 0.05) 0px 1px 1px 0px`,<br>`rgba(97, 104, 117, 0.05) 0px 2px 2px 0px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgba(101, 106, 118, 0.2) 0px 0px 0px 1px` | 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 |
|--------------|-------|---------------|
| `--mds-form-toggle-transition-timing-function` | `cubic-bezier(0.68,-0.2,0.265,1.15)` | cubic-bezier(0.68,-0.2,0.265,1.15) |

### Duration Scale

| CSS Variable | Value | Tier |
|--------------|-------|------|
| `--mds-form-toggle-transition-duration` | `0.2s` | Normal |
| `--mds-tabs-indicator-transition-duration` | `0.6s` | Slow |
| `--mds-form-radiocard-transition-duration` | `0.2s` | Normal |

### Copy-Paste Transition Snippets

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 14 unique animations (14 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 the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use #ffe543 (`#ffe543`) as the primary accent — it's the brand's signature interactive color
- Use small 5px radius for buttons — this design system uses subtle rounding, not pill shapes
- Use 6px border-radius on cards — consistent with the grid card corners
- Style form inputs with a `1px solid rgb(97, 104, 117)` border — use border-based inputs, not floating labels or underline-only
- Maintain nav height at 64px — consistent vertical space for the navigation bar
- Respect the 6px–64px spacing range — the design uses a wide scale for visual breathing room
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Each card includes a top image — imagery is part of the card identity, not optional
- Use a 4-column grid on desktop — density matters for this content type
- Include a newsletter signup in the footer — email capture is part of the conversion funnel

### Don't
- 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 over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
- 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 `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 `#ffe543` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#ffe543\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 375px | Single column, compact spacing |
| Mobile | 460px | Single column, compact spacing |
| Mobile Large | 650px | Expanded mobile layout |
| Mobile Large | 744px | Expanded mobile layout |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1119px | Full feature layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `82px` | `42px` |
| heading | line-height | `95.9974px` | `49.9968px` |
| card | width | `383.328px` | `340px` |

### Collapsing Strategy
- Headlines: 82px → 42px 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.
- **Card grid: 4-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.

## 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://www.datocms-assets.com/2885/1713789521-hashicorp-social-card.png?auto=format&fit=max&w=1200 (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: 2.7:1 (ultra-wide cinematic)
- Rendered size: 1216×450px
- Alt text: "Image of HashiCorp Cloud Platform dashboard"
- *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): 25 (96%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)
- Ultra-wide (>2.3): 1 (4%)

**Media Format Mix:**
- WebP: 3 (optimized photo/illustration hybrid)
- SVG: 5 (icons, illustrations, decorative geometry)

**Average rendered image size:** 396×232px
**Above-fold image count:** 1 / 26

**Decorative Patterns Detected:**
- 3 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 4 large decorative SVG shapes (≥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:**
- 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: Pure White (`#ffffff`)
- Primary text: Brand Logomark (`#000000`)
- Accent: #ffe543 (`#ffe543`)
- Border: Dark Gray (`#3b3d45`)
- Font: dejavu-sans-mono-web
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 82px dejavu-sans-mono-web weight 600, line-height 1.17, color #000000."
- "Create the primary CTA button: `#ffe543` background, `#ffffff` text, 5px border-radius, 9px 15px padding, 500 weight, dejavu-sans-mono-web font."
- "Design a card on `#ffffff` background. Border: none. Radius: 6px. Shadow: use extracted shadow. Padding: 0px."
- "Build navigation: static on `#ffffff`. dejavu-sans-mono-web 16px weight 500 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in dejavu-sans-mono-web, weight range 300–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: #ffe543 (`#ffe543`) is the sole interactive color. On hover → #feec7b (`#feec7b`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.5,0.2,0.2,0.5)`. Timing: 200ms for micro-interactions, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `4px`, cards at `6px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (6px–64px). 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:
    - "Sur la première marche"
    - "Témoignages clients"
    - "Booking.com : synergie tech et innovation agile"
    - "Passez à l'étape suivante avec HashiCorp"
  ctas:
    - "Plate-forme"
    - "Nous contacter"
    - "S'inscrire gratuitement"
  navigation:
    - "Log in"
    - "Nous contacter"
    - "S'inscrire gratuitement"
    - "Plateforme Cloud HashiCorp"
    - "BoundaryAccès distant sécurisé"
    - "Pricing"
    - "Documentation"
    - "Certifications"
    - "Intégrations"
  footer-links:
    - "Privacy Policy"
    - "Terraform"
    - "GitHub"
```

**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: 2

**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">
  Plate-forme
</button>
```
_Source pattern detected: padding `8px 12px` · radius `4px` · weight `500`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `0px` · radius `6px` · shadow `rgba(101, 106, 118, 0.2) 0px 0px 0px 1px`_

**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:*

- **1 parasitic shadow(s) detected** — colored box-shadows (not near-black) found in allShadows. These likely originate from browser extensions or third-party injected widgets (e.g. Grammarly, chat overlays), not from the site's own design system. Discard them when building.
