narrative: |
  tradingview.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses #2979ff as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Roboto as the primary typeface.

# Design System — tradingview.com
> Extracted automatically by Clone Architect from https://www.tradingview.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**: `#2979ff` for primary CTAs ONLY. Never decorative.
> - **Body type**: 14px (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.
>
> **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

tradingview.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 **Ubuntu** with OpenType utility features (`"lnum", "tnum"`) for data-dense contexts. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. 

Body text reads in Jet Black (`#0f0f0f`) — softened from pure black, a small but deliberate detail that lowers reading friction (contrast ratio 17.0:1, well above WCAG AA). **Ring Blue** (`#2979ff`) 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: White (`#ffffff`)
- Primary typeface: EuclidCircularSemibold
- Primary text: Jet Black (`#0f0f0f`)
- Accent: Ring Blue (`#2979ff`)
- Shadow system: 2 distinct elevation levels
- Custom fonts loaded: EuclidCircularSemibold

## 3. Typography Rules

### Font Families
- **Primary**: `-apple-system`
- **Secondary**: `EuclidCircularSemibold`

### Custom Fonts Loaded
- **EuclidCircularSemibold** weight 600 (normal)

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | EuclidCircularSemibold | 64px | 600 | 1 | -2.56px | Main headline (h2) |
| Sub-heading | Ubuntu | 28px | 600 | 1.29 | normal | Third-level heading (h3) |
| Caption / Badge | Ubuntu | 28px | 700 | normal | normal | small text (28px) |
| Eyebrow / Overline | Ubuntu | 28px | 400 | 1.43 | normal | Label above heading, uppercase tag |
| Button Large | Ubuntu | 16px | 500 | 1.5 | 0.3px | Button label (16px) |
| Body | Ubuntu | 14px | 400 | normal | normal | Standard reading text |
| Card Title | Ubuntu | 10px | 600 | 1.6 | normal | Card headings |

### Full Font Size Scale

Sizes detected in the design (descending): `64px`, `40px`, `36px`, `28px`, `24px`, `20px`, `18px`, `16px`, `14px`, `12px`, `11px`, `10px`

> 7 size(s) detected outside the sampled hierarchy (40px, 36px, 24px, 20px, 18px, 12px, 11px). 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
- **lining figures** (`lnum`) — full-height numbers, more authoritative than old-style

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

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **NavLink**:
  - **hover:** bg transparent → #000000

*State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*

```yaml

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
2360px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 56px |
| md | 12px |
| base | 16px |
| lg | 24px |
| 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 | 14px | Cards, containers |
| Lg | 20px | Large rounded elements, pill segments |
| Xl | 32px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `0px` |
| Navigation | `none` |
| Rating Display | `0px` |
| CTA Banners | `0px` |
| Status Badges | `0px` |
| Tabs | `0px` |
| Alerts | `0px` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 0px, 4px, 6px, 7px, 8px, 9px, 10px, 12px (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** | `56px` | 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).

**6/8 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:** "The best trades require research, then commitment." — 28px left-aligned

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0.2) 0px 2px 4px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgb(255, 76, 161) 16px 0px 45.9067px -12px`,<br>`rgb(14, 78, 255) -16px 0px 45.9067px -12px` | 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 |
|-------|---------------|
| `ease-in-out` | Ease In-Out — Symmetric |
| `ease-in` | Ease In — Accelerating |
| `ease` | CSS ease — Default |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `500ms` | Slow | Hero animations, page transitions |

### Copy-Paste Transition Snippets

**Transform**
```css
transition: transform 0.5s ease-in-out, opacity 0.5s ease-in-out;
```

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `500ms`)
- **Dominant Easing**: symmetric in-out (precise)
- **Animation Library**: 27 unique animations (27 total including variants)

> This design moves with deliberate & calm timing using symmetric in-out (precise), creating a UI that feels calm and controlled.

## 8. Do's and Don'ts

### Do
- Use Text Primary (`#0f0f0f`) for text — not pure black, it's warmer and more readable
- Use Ubuntu 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 Ring Blue (`#2979ff`) as the primary accent — it's the brand's signature interactive color
- Use 40px border-radius on primary buttons — the brand uses generously-rounded CTAs
- Maintain nav height at 64px — 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 hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Each card includes a top image — imagery is part of the card identity, not optional
- Show company logos with testimonials — social proof relies on brand recognition, not avatars
- Lay out testimonials in a grid (36+ items) — quantity signals scale and trust

### 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 — 40px 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
- Don't make the nav sticky — this design lets it scroll away to maximize content focus
- Don't put a CTA button in the nav — this design uses links only at the top


## 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 `#2979ff` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#2979ff\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 320px | Single column, compact spacing |
| Mobile | 479px | Single column, compact spacing |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1019px | Multi-column grids begin |
| Desktop | 1280px | Full feature layout |
| Large Desktop | 1439px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | display | `flex` | `none` |
| nav | height | `64px` | `auto` |

### Collapsing Strategy
- Navigation: flex → none on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 2px 4px 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):

- **Hero CTAs:** 2 on desktop → 1 on mobile (secondary CTAs dropped on small screens).

## 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://s.tradingview.com/static/images/illustrations/main-page.jpg (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: 1.49:1 (landscape)
- Rendered size: 1440×965px
- *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): 22 (92%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 2 (8%)

**Media Format Mix:**
- WebP: 3 (optimized photo/illustration hybrid)
- PNG: 20 (logos, transparent UI elements, mockups)
- SVG: 5 (icons, illustrations, decorative geometry)

**Average rendered image size:** 476×280px
**Above-fold image count:** 2 / 24

**Decorative Patterns Detected:**
- 1 multi-stop linear gradient (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
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic

**Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content.

**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: White (`#ffffff`)
- Primary text: Jet Black (`#0f0f0f`)
- Accent: Ring Blue (`#2979ff`)
- Border: Charcoal (`#2e2e2e`)
- Font: Ubuntu
- Body: 14px weight 400

### Example Component Prompts
- "Create a hero section on White background (#ffffff). Headline at 28px Ubuntu weight 700, line-height normal, color #0f0f0f."
- "Create the primary CTA button: `#2979ff` background, `#0f0f0f` text, 9999px border-radius, 2px 4px padding, 700 weight, Ubuntu font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#ffffff`. Ubuntu 14px 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 Ubuntu, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Ring Blue (`#2979ff`) is the sole interactive color. On hover → #0097a7 (`#0097a7`). 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 (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.

```

**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:
    - "Where the world does markets"
    - "Market summary"
    - "US stocks"
  sub-headings:
    - "Community ideas"
  ctas:
    - "Skip to main content"
    - "Search"
    - "EN"
    - "Get started"
    - "Explore features"
    - "See all major indices"
  navigation:
    - "Products"
    - "Community"
    - "Markets"
    - "Brokers"
    - "More"
    - "US stocks"
    - "Crypto"
    - "Futures"
    - "Forex"
    - "Economy"
  footer-links:
    - "ICE Data Services"
    - "Supercharts"
```

**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: 10
    avg-ratio: 2.00
    common-aspect: "~16:9 landscape"
  thumbnail:
    count: 27
    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">
  Skip to main content
</button>
```
_Source pattern detected: padding `2px 4px` · 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.
