narrative: |
  nvidia.com is built on a pure-white canvas (rgb(255,255,255)).
  The system uses #76b900 as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside NVIDIA-EMEA as the primary typeface.

> Extracted automatically by Clone Architect from https://nvidia.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(255,255,255)` is the page background. Every component composits against this.
> - **Accent**: `#76b900` 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**: 2px 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

nvidia.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 **NVIDIA-EMEA**. 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 Black (`#000000`) (contrast ratio 100.0:1, well above WCAG AA). **Brand Green** (`#76b900`) 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. 
Sharp, zero-radius corners throughout reinforce a structured, grid-based aesthetic. Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: White (`#ffffff`)
- Primary typeface: NVIDIA-NALA
- Accent: Brand Green (`#76b900`)
- Shadow system: 4 distinct elevation levels
- Custom fonts loaded: NVIDIA-NALA, NVIDIA-EMEA, NVIDIA-RU, NVIDIA-APAC, NVIDIA-CN, NVIDIA, Heebo, Source-Han-Sans-SC, Source-Han-Sans-TC, Source-Han-Sans-KR, Source-Han-Sans-JP, hushly

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | NVIDIA-EMEA | 36px | 700 | 1.25 | normal | Main headline (h2) |
| Caption / Badge | Font Awesome 6 Brands | 24px | 400 | 1 | normal | small text (24px) |
| Body | NVIDIA-EMEA | 16px | 400 | normal | normal | Standard reading text |
| Micro | NVIDIA-EMEA | 11px | 700 | 1 | normal | small text (11px) |

### Font Weight Scale

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

### Full Font Size Scale

Sizes detected in the design (descending): `48px`, `36px`, `28px`, `24px`, `22px`, `20px`, `18px`, `16px`, `15px`, `14px`, `12px`, `11px`, `10px`

> 9 size(s) detected outside the sampled hierarchy (48px, 28px, 22px, 20px, 18px, 15px, 14px, 12px, 10px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

```

**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
- **1 shape(s)** in this system: `Ghost`
- **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

### Status Badges
- **2 shape(s)** in this system: `Neutral Dark`, `Neutral Dark`
- **DO NOT introduce new status badges variants** without justification

### Tabs
- **1 shape(s)** in this system: `Ghost Tab`
- **DO NOT introduce new tabs variants** without justification

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
346px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 8px |
| md | 12px |
| base | 16px |
| lg | 24px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 2px | Tiny corners (badges, micro elements) |
| Sm | 2px | Buttons, inputs, small elements |
| Md | 2px | Cards, containers |
| Lg | 2px | Large rounded elements, pill segments |
| Xl | 2px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `0px` |
| Navigation | `none` |
| Status Badges | `0px` |
| Tabs | `0px` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 0px, 2px (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** | `8px` | Form fields, tight clusters, badge padding |
| **micro** | `4px` | 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:** fixed (stays visible during scroll)
- **Layout:** unknown — Layout not classified
- **Height:** 45px
- **Logo:** ✓ present
- **Nav links:** 7 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Search:** ✓ search input visible in nav
- **Clone instruction:** Build a fixed unknown navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 9 cards detected
- **Columns (desktop):** 3-up grid
- **Card dimensions:** 428×724px (aspect 0.59:1)
- **Gap:** 30px between cards
- **Content:** ✗ no image
- **Clone instruction:** Build a 3-column grid (desktop) with cards at ~0.59:1 aspect ratio. Text/icon-only cards (no photography).

### Footer Pattern

- **Columns:** 1
- **Links:** 0 total
- **Height:** 16px
- **Includes:** ✗ no newsletter | ✗ no social |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~0 links per column, 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, 0.19) 0px 2px 6px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.2) 3px 0px 15px 0px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgba(0, 0, 0, 0.24) 0px 3px 4.7px 0.3px`,<br>`rgba(0, 0, 0, 0.16) 0px 1px 5.88px 0.12px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgba(0, 0, 0, 0.3) 0px 0px 5px 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 |
|-------|---------------|

## 8. Do's and Don'ts

### Do
- Use NVIDIA-EMEA 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 Brand Green (`#76b900`) as the primary accent — it's the brand's signature interactive color
- Keep navigation fixed to the top — the design uses a persistent navigation pattern
- Maintain nav height at 45px — consistent vertical space for the navigation bar
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Make the navigation fixed — it stays visible during scroll, signaling content depth
- Include a search input directly in the nav — discoverability is a primary UX value here
- Use a 3-column grid on desktop — density matters for this content type

### Don't
- 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 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, 0 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(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 `#76b900` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#76b900\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 374px | Single column, compact spacing |
| Mobile | 480px | Single column, compact spacing |
| Mobile Large | 639px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 1023px | Multi-column grids begin |
| Large Desktop | 1290px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| button | padding | `5px 0px 5px 15px` | `5px 15px` |

### 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: 5px 0px 5px 15px 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://www.nvidia.com/content/dam/en-zz/Solutions/homepage/v2/mfg/nvidia-og-image-1200x630.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: 3.32:1 (ultra-wide cinematic)
- Rendered size: 2560×770px
- *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): 58 (64%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 31 (34%)
- Ultra-wide (>2.3): 1 (1%)

**Media Format Mix:**
- JPG: 48 (typically photographic content)
- PNG: 11 (logos, transparent UI elements, mockups)

**Average rendered image size:** 424×293px
**Above-fold image count:** 1 / 90

**Decorative Patterns Detected:**
- 2 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth

**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: White (`#ffffff`)
- Primary text: Black (`#000000`)
- Accent: Brand Green (`#76b900`)
- Border: Dim Gray (`#666666`)
- Font: NVIDIA-EMEA
- Body: 16px weight 400

### Example Component Prompts
- "Create the primary CTA button: `#76b900` background, `#222222` text, 9999px border-radius, 5px 0px 5px 15px padding, 700 weight, NVIDIA-EMEA font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px 0px 0px 20px."
- "Build navigation: fixed on `#ffffff`. NVIDIA-EMEA 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to White (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in NVIDIA-EMEA, weight range 300–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Brand Green (`#76b900`) is the sole interactive color. On hover → Brand Green (`#76b900`). Use CSS transitions, not opacity/brightness filters.
4. **Shape**: cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
5. **Spacing**: Use the `--ca-space-*` token scale (4px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
6. **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.*

**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:
    - "Lancement du CPU NVIDIA Vera, conçu pour l'IA agentique"
    - "Ressources recommandées"
  sub-headings:
    - "Intelligence Artificielle"
    - "Focus sur l'économie des jetons d'IA pour les télécommunications"
    - "Présentation de NVIDIA Ising"
    - "NVIDIA, T-Mobile et leurs partenaires activent des agents d'IA à l'Edge sur AI-RAN"
    - "aNVIDIA annonce un accès anticipé pour Omniverse Sensor RTXNVIDIA Announces Nemotron Model Families"
    - "NVIDIA Unveils OaNVIDIA dévoile un jeu de données d'IA physique ouvert, le plus grand jeu de données"
  navigation:
    - "Continue"
    - "Skip to main content"
    - "Modèles d'IA agentique - Nemotron"
    - "Agents d'IA - NeMo"
    - "AI Blueprints"
    - "Inférence de l'IA - Dynamo"
    - "Inférence de l'IA - NIM"
    - "Microservices d'IA - CUDA-X"
    - "Automobile - DRIVE"
    - "Data Science - Apache Spark"
```

**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: 3.32
    common-aspect: "~16:6 banner"
```

**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`.

## 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 | 204 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | Medium | 4 typography roles inferred |
| §4 Components | High | 5 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 15 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 90 images, hero present |
