narrative: |
  cohere.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(255, 119, 89) as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Unica77 Cohere Web as the primary typeface.

>
> - **Canvas**: `rgb(255, 255, 255)` is the page background. Every component composits against this.
> - **Accent**: `rgb(255, 119, 89)` 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.

## 1. Visual Theme & Atmosphere

cohere.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 **Unica77 Cohere Web**. 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 (-1.92px at 96px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Pure Black (`#000000`) (contrast ratio 100.0:1, well above WCAG AA). **Coral** (`#ff7759`) 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. 
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. The site uses a variable font with CUTS + MOVE axes, enabling precise weight/width control across the type hierarchy. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: CohereText
- Accent: Coral (`#ff7759`)
- Display: 96px weight 400, letter-spacing -1.92px
- Shadow system: 2 distinct elevation levels
- Custom fonts loaded: CohereText, CohereHeadline, CohereMono, CohereVariable, CohereColor, Unica77 Cohere Web

**Full Radius Spectrum**: 0px, 2px, 4px, 6px, 8px, 12px, 16px, 50px (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** | `16px` | Card padding, list-item spacing |
| **compact** | `12px` | 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).

**5/8 structural patterns detected.**

### Hero Pattern

- **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages.
- **Viewport coverage:** 466px tall (not full-viewport)
- **Heading:** "Own your AI" — 96px center-aligned
- **Subheading:** "Your data. Your infrastructure. Cohere keeps it that way."
- **CTAs:** 1 (primary: "Request a demo")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. No imagery needed for hero — text-driven.

### Navigation Pattern

- **Position:** fixed (stays visible during scroll)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 76px
- **Logo:** ✓ present
- **Nav links:** 52 primary items
- **CTAs in nav:** 1
- **Clone instruction:** Build a fixed logo left links left navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Card count:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1427×847px (aspect 1.69:1)
- **Gap:** 0px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.69:1 aspect ratio. Each card has an image at the top.

### CTA Banner Pattern

- **Banner count:** 3
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Go North"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.

### Footer Pattern

- **Columns:** 1
- **Links:** 45 total
- **Height:** 1334px
- **Includes:** ✓ newsletter signup | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~45 links per column, newsletter signup, 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(172, 171, 171, 0.3) 0px -1px 10px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.3) 0px 32px 68px 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

### Dominant Easing Curves

| Curve | Semantic Name |
|-------|---------------|
| `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced |
| `ease-in-out` | Ease In-Out — Symmetric |
| `ease-in` | Ease In — Accelerating |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `150ms` | Fast | Hover states, micro-interactions |
| `300ms` | Normal | Panel open/close, navigation |
| `500ms` | Slow | Hero animations, page transitions |

### Copy-Paste Transition Snippets

> 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 Unica77 Cohere Web as the primary typeface — it defines the brand personality
- Keep font weights between 400-500 — the system uses a narrow weight range for subtle hierarchy
- Use negative letter-spacing (-1.92px) at display sizes for compressed, editorial headlines
- 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 Coral (`#ff7759`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Use 22px border-radius on cards — consistent with the grid card corners
- Keep navigation fixed to the top — the design uses a persistent navigation pattern
- Maintain nav height at 75.5938px — consistent vertical space for the navigation bar
- Keep the hero centered and text-driven — no decorative media, typography carries the message
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Make the navigation fixed — it stays visible during scroll, signaling content depth
- Each card includes a top image — imagery is part of the card identity, not optional
- Repeat the primary CTA across 3 banner sections — conversion paths are layered, not single
- Include a newsletter signup in the footer — email capture is part of the conversion funnel

### Don't
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't use weight 700 (bold) or above — 500 is the maximum weight in this system
- 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 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 use rectangular buttons for primary actions — the rounded pill shape is the brand standard
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't add hero illustrations or photos — they'll break the typographic restraint


## 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 `rgb(255, 119, 89)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(255, 119, 89)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 460px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1023px | Multi-column grids begin |
| Desktop | 1280px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `96px` | `60px` |
| heading | line-height | `96px` | `60px` |
| heading | letter-spacing | `-1.92px` | `-1.2px` |
| nav | padding | `16px 40px` | `20px 16px` |
| nav | height | `75.5938px` | `72px` |
| card | width | `420px` | `289px` |

### Collapsing Strategy
- Headlines: 96px → 60px 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):

- **Navigation collapses to hamburger** — 52 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle).
- **Nav CTAs reduced** on mobile (1 → 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://cdn.sanity.io/images/rjtqmwfu/web3-prod/b966213f9f46bb9cec6ec5a3406e893530b8b292-1200x630.png?w=1200&h=630 (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: 1.61:1 (landscape (16:9-ish))
- Rendered size: 899×560px
- Alt text: "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): 81 (92%)
- Portrait (<0.87): 1 (1%)
- Square (0.87–1.15): 3 (3%)
- Ultra-wide (>2.3): 3 (3%)

**Media Format Mix:**
- WebP: 3 (optimized photo/illustration hybrid)
- PNG: 5 (logos, transparent UI elements, mockups)
- SVG: 82 (icons, illustrations, decorative geometry)

**Average rendered image size:** 189×108px
**Above-fold image count:** 8 / 88

**Decorative Patterns Detected:**
- 18 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 2 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: Pure White (`#ffffff`)
- Primary text: Pure Black (`#000000`)
- Accent: Coral (`#ff7759`)
- Border: Charcoal (`#2e2e2e`)
- Font: Unica77 Cohere Web
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 96px Unica77 Cohere Web weight 400, line-height 1, letter-spacing -1.92px, color #000000."
- "Create the primary CTA button: `#ff7759` background, `#212121` text, 999px border-radius, 11px 21px padding, 500 weight, Unica77 Cohere Web font."
- "Design a card on `transparent` background. Border: none. Radius: 22px. Shadow: none. Padding: 0px."
- "Build navigation: fixed on `#ffffff`. Unica77 Cohere Web 16px weight 400 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 Unica77 Cohere Web, weight range 400–500. Never exceed 500 — heavier weights break the brand's tonal restraint.
3. **Accent**: Coral (`#ff7759`) is the sole interactive color. On hover → Transparent (`transparent`). 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 `0px`, cards at `22px`. 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:
    - "Powering progress across industries"
    - "Ready to put AI to work?"
  sub-headings:
    - "Safe. Flexible. Independent."
    - "Your sovereign AI workplace"
    - "Developer resources"
    - "“With Cohere's latest highly secure enterprise LLMs, we aim to provide businesses with powerful and"
  navigation:
    - "Learn more"
    - "Products"
    - "CUSTOMIZATION"
    - "PRICING"
    - "Solutions"
    - "Technology"
    - "Financial Services"
    - "Healthcare and Life Sciences"
    - "Manufacturing"
    - "Energy and Utilities"
  footer-links:
    - "Request a demo"
    - "privacy policy"
    - "Products"
    - "North"
```

**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: 30
    avg-ratio: 1.89
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "Oracle Logo"
      - "Dell Technologies Logo"
      - "RBC Logo"
  product:
    count: 3
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
  thumbnail:
    count: 1
    avg-ratio: 1.00
    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 `0px` · radius `22px` · 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.
