narrative: |
  nike.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses #FF5000 as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Helvetica Now Text 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**: `#FF5000` 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: 48px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.

## 1. Visual Theme & Atmosphere

nike.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 **Helvetica Now Text**. 

Body text reads in Jet Black (`#111111`) — softened from pure black, a small but deliberate detail that lowers reading friction (contrast ratio 15.0:1, well above WCAG AA). **Bright Orange** (`#ff5000`) 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. 


**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: Nike TG
- Primary text: Jet Black (`#111111`)
- Accent: Bright Orange (`#ff5000`)
- Display: 24px weight 500
- Shadow system: 2 distinct elevation levels
- Custom fonts loaded: Nike TG, Nike Futura ND, Nike Futura, Helvetica Now Text, Helvetica Now Text Medium, Helvetica Now Display Medium, Palatino LT Pro Light, VideoJS, Helvetica Now Display Bold, Helvetica Now Display XBold

### Font Weight Scale

CSS custom properties define 3 explicit weight steps:
- `--podium-cds-font-weight-regular`: `400` — Regular
- `--podium-cds-font-weight-medium`: `500` — Medium
- `--podium-cds-font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `76px`, `32px`, `24px`, `20px`, `19.20px`, `16px`, `14px`, `13.33px`, `12px`, `9px`

> 6 size(s) detected outside the sampled hierarchy (32px, 20px, 19.2px, 13.3333px, 12px, 9px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
1920px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 5px |
| sm | 7px |
| md | 12px |
| base | 16px |
| lg | 48px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 2px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 18px | Cards, containers |
| Lg | 18px | Large rounded elements, pill segments |
| Xl | 30px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `0px` |
| Inputs & Forms | `24px` |
| Navigation | `none` |
| Search Bar | `0px` |
| CTA Banners | `0px` |
| Page Body | `0px` |
| Primary Input | `24px` |

**Shape Personality**: Generously Rounded — Soft, friendly corners (8px+). Approachable, consumer-facing feel.

**Full Radius Spectrum**: 0px, 2px, 8px, 18px, 24px, 30px (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** | `48px` | Within a section, between content groups |
| **card** | `12px` | Card padding, list-item spacing |
| **compact** | `7px` | Form fields, tight clusters, badge padding |
| **micro** | `5px` | 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:** 96px
- **Logo:** ✓ present
- **Nav links:** 211 primary items
- **CTAs in nav:** 1
- **Search:** ✓ search input visible in nav
- **Clone instruction:** Build a fixed unknown navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Card count:** 12 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1392×683px (aspect 2.04:1)
- **Gap:** 16px between cards
- **Content:** ✓ image
- **Image position:** none
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~2.04:1 aspect ratio. Each card has an image at the none.

### Footer Pattern

- **Columns:** 1
- **Links:** 44 total
- **Height:** 677px
- **Includes:** ✗ no newsletter | ✗ no social |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~44 links per column, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Inset (Level 1) | <br>`rgb(229, 229, 229) 0px -1px 0px 0px inset` | Buttons, pressed-state elements |
| Layered (Level 2) | <br>`rgba(17, 17, 17, 0.06) 0px 4px 8px 0px`,<br>`rgba(17, 17, 17, 0.03) 0px 0px 24px 4px` | Cards, elevated surfaces |

**Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 37 unique animations (37 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 Jet Black (`#111111`) for text — not pure black, it's warmer and more readable
- Use Helvetica Now Text 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 Bright Orange (`#ff5000`) as the primary accent — it's the brand's signature interactive color
- Use 30px border-radius on primary buttons — the brand uses generously-rounded CTAs
- Keep navigation fixed to the top — the design uses a persistent navigation pattern
- Maintain nav height at 96px — consistent vertical space for the navigation bar
- 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
- Each card includes a none image — imagery is part of the card identity, not optional

### Don't
- Don't use pure black (`#000000`) for text — the near-black adds warmth
- 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 use sharp-cornered or pill buttons — 30px is the CTA border-radius standard
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence


## 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 `#FF5000` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#FF5000\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 320px | Single column, compact spacing |
| Mobile | 375px | Single column, compact spacing |
| Mobile Large | 599px | Expanded mobile layout |
| Mobile Large | 639px | Expanded mobile layout |
| Tablet | 1023px | Multi-column grids begin |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | height | `96px` | `60px` |
| button | width | `56px` | `36px` |
| card | width | `auto` | `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):

- **Navigation collapses to hamburger** — 211 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle).

## 9b. Visual Tone & Photography

**Tone:** Mixed photography + illustration

A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents.

**Canonical Brand Image (OG):**
- https://c.static-nike.com/a/images/w_1920,c_limit/mdbgldn6yg1gg88jomci/image.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: 2.06:1 (landscape (16:9-ish))
- Rendered size: 1440×700px
- Alt text: "CHOISIS TA VITESSE, Place aux nouvelles Mercurial."
- *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): 10 (77%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 3 (23%)

**Media Format Mix:**
- JPG: 3 (typically photographic content)
- PNG: 10 (logos, transparent UI elements, mockups)

**Average rendered image size:** 569×415px
**Above-fold image count:** 2 / 13

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

**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:**
- Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents.
- Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Pure White (`#ffffff`)
- Primary text: Jet Black (`#111111`)
- Accent: Bright Orange (`#ff5000`)
- Border: Stone (`#707072`)
- Font: Helvetica Now Text
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 24px Helvetica Now Text weight 500, line-height 1.35, color #111111."
- "Create the primary CTA button: `#ff5000` background, `#111111` text, 9999px border-radius, 12px 24px padding, 500 weight, Helvetica Now Text font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: fixed on `#ffffff`. Helvetica Now Text 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 Helvetica Now Text, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Bright Orange (`#ff5000`) is the sole interactive color. On hover → Red (`#ee0005`). Use CSS transitions, not opacity/brightness filters.
4. **Shape**: CTAs at `0px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
5. **Spacing**: Use the `--ca-space-*` token scale (5px–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.

```

**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:
    - "Nos modèles iconiques"
    - "Promotions liées à la communauté"
  sub-headings:
    - "CHOISIS TA VITESSE"
    - "Pour les enfants qui bougent"
  ctas:
    - "Acheter"
  navigation:
    - "Passer au contenu principal"
    - "Trouver un magasin"
    - "Aide"
    - "Rejoins-nous"
    - "S'identifier"
    - "Nouveau"
    - "Homme"
    - "Femme"
  footer-links:
    - "Ressources"
    - "Cartes cadeaux"
```

**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: 2.06
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "CHOISIS TA VITESSE, Place aux nouvelles Mercurial."
  product:
    count: 3
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - " Prêt à briller sur la plus grande scène., Paris Saint-Germa"
      - "Ballet sur terre battue, Nike Tennis"
      - "Air Max 90 \"Laser 90\", Against the Grain"
```

**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 `500`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `0px` · radius `0px` · shadow `none`_

**Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling.
