narrative: |
  ibm.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(0, 98, 254) as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside IBM Plex Sans as the primary typeface.

>
> - **Canvas**: `rgb(255, 255, 255)` is the page background. Every component composits against this.
> - **Accent**: `rgb(0, 98, 254)` 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: 64px.
> - **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

ibm.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 **IBM Plex Sans**. Headlines run at a remarkably light weight (300) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. 

Body text reads in Jet Black (`#161616`) — softened from pure black, a small but deliberate detail that lowers reading friction. **#0062fe** (`#0062fe`) 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. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: IBM Plex Mono
- Primary text: Jet Black (`#161616`)
- Accent: #0062fe (`#0062fe`)
- Display: 53.6469px weight 300
- Shadow system: 8 distinct elevation levels
- Custom fonts loaded: IBM Plex Mono, IBM Plex Sans, IBM Plex Serif, IBM Plex Sans Hebrew, IBM Plex Sans Arabic, IBM Plex Sans JP, IBM Plex Sans KR

### Full Font Size Scale

Sizes detected in the design (descending): `53.65px`, `42px`, `32px`, `21.88px`, `20px`, `18px`, `16px`, `14px`, `13.33px`, `13px`, `12px`

> 5 size(s) detected outside the sampled hierarchy (42px, 21.8824px, 18px, 13.3333px, 13px). 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:

- **ligatures** — common letter pairs replaced with refined glyphs (fi, fl, etc.)

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

## 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 | 32px |
| base | 48px |
| lg | 64px |
| 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 | 16px | Large rounded elements, pill segments |
| Xl | 16px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

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

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

**Full Radius Spectrum**: 0px, 2px, 4px, 5px, 8px, 12px, 16px, 80px (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** | `64px` | Within a section, between content groups |
| **card** | `32px` | 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.**

### 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:** "Construisez des Infrastructures modernes" — 54px left-aligned
- **Subheading:** "Construisez des Infrastructures modernes Menaces persistantes ? Misez sur la cyber-résilience. Avec IBM FlashSystem, sécurisez votre infrastructure et"
- **CTAs:** none detected in hero (unusual — agent should verify)
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. No imagery needed for hero — text-driven.

### Card Grid Pattern

- **Card count:** 4 cards detected
- **Columns (desktop):** 4-up grid
- **Card dimensions:** 340×178px (aspect 1.91:1)
- **Gap:** 16px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 4-column grid (desktop) with cards at ~1.91:1 aspect ratio. Each card has an image at the top.

### Footer Pattern

- **Columns:** 2
- **Links:** 0 total
- **Height:** 633px
- **Includes:** ✗ no newsletter | ✗ no social |  
- **Clone instruction:** Build a 2-column footer with ~0 links per column.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0.3) 0px 2px 6px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgb(255, 255, 255) 0px 0px 0px 1440px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgb(128, 128, 128) 0px 0px 10px 0px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgb(42, 42, 42) 1px 5px 5px 3px` | 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(0.2,0,0.38,0.9)` | Ease Out — Decelerating |
| `cubic-bezier(0.4,0.14,0.3,1)` | Ease Out — Decelerating |
| `ease-in-out` | Ease In-Out — Symmetric |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `70ms` | Fast | Hover states, micro-interactions |
| `150ms` | Fast | Hover states, micro-interactions |
| `240ms` | Normal | Panel open/close, navigation |
| `300ms` | Normal | Panel open/close, navigation |

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `240ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 76 unique animations (76 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 Jet Black (`#161616`) for text — not pure black, it's warmer and more readable
- Use IBM Plex Sans as the primary typeface — it defines the brand personality
- Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy
- Use the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use #0062fe (`#0062fe`) as the primary accent — it's the brand's signature interactive color
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Keep the hero centered and text-driven — no decorative media, typography carries the message
- 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

### 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 use weight 700 (bold) or above — 600 is the maximum weight in this system
- 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 add hero illustrations or photos — they'll break the typographic restraint
- Don't over-build the footer — this design keeps it minimal (2 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 `rgb(0, 98, 254)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(0, 98, 254)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 320px | Single column, compact spacing |
| Mobile | 480px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 760px | Expanded mobile layout |
| Tablet | 1023px | Multi-column grids begin |
| Desktop | 1099px | Full feature layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `53.6469px` | `32.7955px` |
| heading | font-weight | `300` | `400` |
| heading | line-height | `62.7669px` | `40.9944px` |
| sidebar | width | `325.328px` | `374px` |

### Collapsing Strategy
- Headlines: 53.6469px → 32.7955px 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: 16px 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: 4-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.
- **Footer columns collapse:** 2 columns (desktop) → 1 column (mobile).

## 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://www.ibm.com/content/dam/connectedassets-adobe-cms/worldwide-content/creative-assets/s-migr/ul/g/18/f9/ibm_logo_pos_blue60_rgb.png/_jcr_content/renditions/cq5dam.thumbnail.1280.1280.png
  *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: 2.02:1 (landscape (16:9-ish))
- Rendered size: 352×174px
- Alt text: "Ampoule avec explosion colorée de pigments bleus, roses et jaunes sur fond sombre"
- *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): 11 (65%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 5 (29%)
- Ultra-wide (>2.3): 1 (6%)

**Media Format Mix:**
- PNG: 5 (logos, transparent UI elements, mockups)

**Average rendered image size:** 273×185px
**Above-fold image count:** 1 / 17

**Decorative Patterns Detected:**
- 11 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 (`#161616`)
- Accent: #0062fe (`#0062fe`)
- Border: Slate (`#525252`)
- Font: IBM Plex Sans
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 53.6469px IBM Plex Sans weight 300, line-height 1.17, color #161616."
- "Create the primary CTA button: `#0062fe` background, `#ffffff` text, 9999px border-radius, 15px 15px 15px 16px padding, 600 weight, IBM Plex Sans font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#ffffff`. IBM Plex Sans 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 IBM Plex Sans, weight range 300–600. Never exceed 600 — heavier weights break the brand's tonal restraint.
3. **Accent**: #0062fe (`#0062fe`) is the sole interactive color. On hover → #0f62fe (`#0f62fe`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.2,0,0.38,0.9)`. 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.

**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:
    - "Produits annoncés à Think 2026"
    - "Technologie pour les entreprises"
    - "Restez connecté"
    - "Abonnement à la newsletter What's New at IBM"
  sub-headings:
    - "Citadelle"
  ctas:
    - "S’abonner"
    - "préférences en matière de cookies"
    - "Tout accepter"
    - "Bonjour ! Comment pouvons-nous vous aider ?"
    - "Fermer"
```

**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: 5
    avg-ratio: 2.00
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "Logo Citadelle "
      - "Logo Serre Chevalier "
      - "Logo Blue Pearl"
  product:
    count: 1
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Logo Think violet avec un morceau de cube et une inscirption"

**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 `16px` · radius `0px` · weight `400`_

### 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.


## 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.

## Extraction Completeness: 88/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 21 | 25 | 15 named colors |
| Typography | 20 | 20 | 9 roles defined |
| Components | 20 | 20 | 6 specs extracted |
| Motion & Interaction | 12 | 15 | Keyframes present |
| CSS Custom Properties | 10 | 10 | 502 vars |
| Responsive Breakpoints | 5 | 5 | 6 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 |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 502 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 9 typography roles inferred |
| §4 Components | High | 6 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 | High | 6 breakpoints detected |
| §9b Photography | High | 17 images, hero present |
