description: "Light product system built on #ffffff with #d73a49 as the primary CTA accent. Type anchored in basier-square at 24px / weight 400. Extracted automatically from https://replicate.com/ — every value from getComputedStyle(), no approximation."
narrative: |
  replicate.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(215, 58, 73) as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside basier-square as the primary typeface.

# Design System — replicate.com
> Extracted automatically by Clone Architect from https://replicate.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**: `rgb(215, 58, 73)` 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

replicate.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 **basier-square**. Headlines run at a remarkably light weight (400) — restraint over assertion, creating an editorial calm that invites reading rather than demanding it. 

Body text reads in Near Black (`#202020`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Vermillion** (`#d73a49`) 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: basier-square
- Primary text: Near Black (`#202020`)
- Accent: Vermillion (`#d73a49`)
- Shadow system: 3 distinct elevation levels
- Custom fonts loaded: basier-square, jetbrains-mono, rb-freigeist-neue

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Button**:
  - **hover:** bg transparent → rgba(0, 0, 0, 0.06)
  - **focus:** shadow added
- **Badge**:
  - **hover:** bg transparent → rgba(0, 0, 0, 0.024)

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

```yaml

**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
- **7 shape(s)** in this system: `Icon Button`, `Icon Button`, `Outline`, `Ghost`, `Pill`
- **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`, `Tinted`
- **DO NOT introduce new status badges variants** without justification

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

### Code Blocks
- **1 shape(s)** in this system: `Inline Code / Pre`
- **DO NOT introduce new code blocks variants** without justification

## 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 | 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` |
| Code Blocks | `0px` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 2px, 4px, full/pill (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.**

### 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:** "Run and fine-tune models. Deploy custom models. All with one line of code." — 24px left-aligned
- **Subheading:** "A poolside patio at sunset with vintage lounge chairs."
- **Media:** present, positioned top
- **CTAs:** 1 (primary: "Get started for free")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. Place media top of text.

### Card Grid Pattern

- **Card count:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1440×798px (aspect 1.8:1)
- **Gap:** 0px between cards
- **Content:** ✗ no image
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.8:1 aspect ratio. Text/icon-only cards (no photography).

### Footer Pattern

- **Columns:** 3
- **Links:** 19 total

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0.25) 0px 25px 50px -12px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 0px`,<br>`rgb(228, 199, 103) 0px 1px 2px 0px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgb(255, 255, 255) 0px 0px 0px 0px`,<br>`rgb(196, 232, 209) 0px 0px 0px 2px`,<br>`rgba(0, 0, 0, 0) 0px 0px 0px 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 |
| `linear` | Linear — No Easing |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `150ms` | Fast | Hover states, micro-interactions |
| `200ms` | Normal | Panel open/close, navigation |
| `500ms` | Slow | Hero animations, page transitions |
| `1s` | Cinematic | Splash, marketing reveals |
| `10s` | Cinematic | Splash, marketing reveals |

### Copy-Paste Transition Snippets

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `500ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 7 unique animations (7 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 Near Black (`#202020`) for text — not pure black, it's warmer and more readable
- Use basier-square 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 full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
- Use Vermillion (`#d73a49`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Transition button background to Translucent Pure Black (6%) (`rgba(0, 0, 0, 0.06)`) on hover — this is the extracted interactive state
- 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
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis

### 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 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 use opacity or brightness filter for button hover — the design uses an explicit background color change


## 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(215, 58, 73)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(215, 58, 73)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 640px | Single column layout |
| Tablet | 768px | 2-column grids |
| Desktop | 1024px | Full layout |
| Large Desktop | 1280px | Maximum width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `24px` | `20px` |
| heading | line-height | `32px` | `28px` |
| button | font-size | `16px` | `14px` |
| button | width | `24px` | `80px` |

### Collapsing Strategy
- Headlines: 24px → 20px 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):

- **Footer columns collapse:** 3 columns (desktop) → 2 columns (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.

**Hero Image (above-fold dominant visual):**
- Aspect: 1.56:1 (landscape (16:9-ish))
- Rendered size: 444×284px
- Alt text: "Generated image: a poolside patio at sunset with vintage lounge chairs"
- *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): 5 (10%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 46 (90%)

**Media Format Mix:**
- JPG: 12 (typically photographic content)
- WebP: 12 (optimized photo/illustration hybrid)
- PNG: 27 (logos, transparent UI elements, mockups)
- SVG: 3 (icons, illustrations, decorative geometry)

**Average rendered image size:** 151×134px
**Above-fold image count:** 5 / 51

**Decorative Patterns Detected:**
- 35 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 1 radial gradient — circular color blooms used for spotlight/glow effects
- 3 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:**
- 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: Pure White (`#ffffff`)
- Primary text: Near Black (`#202020`)
- Accent: Vermillion (`#d73a49`)
- Border: #d9d9d9 (`#d9d9d9`)
- Font: basier-square
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 24px basier-square weight 400, line-height 1.33, color #202020."
- "Create the primary CTA button: `#d73a49` background, `#202020` text, 9999px border-radius, 12px 24px padding, 700 weight, basier-square font."
- "Design a card on `transparent` background. Border: 4px solid rgba(0, 0, 0, 0). Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#ffffff`. basier-square 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 basier-square, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Vermillion (`#d73a49`) is the sole interactive color. On hover → Slate Blue (`#6f42c1`). 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 `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (4px–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:
    - "Run AI
with an API."
    - "Thousands of models contributed by our community"
    - "How it works"
    - "Scale on Replicate"
  sub-headings:
    - "Run models"
  ctas:
    - "Get started for free"
    - "Node"
    - "Python"
    - "black-forest-labs/flux-2-pro"
  navigation:
    - "Explore"
    - "Pricing"
    - "Enterprise"
    - "Docs"
    - "Blog"
    - "Sign in"
    - "Try for free"
  footer-links:
    - "Explore"
    - "All services are online"
```

**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:
  product:
    count: 16
    avg-ratio: 1.04
    common-aspect: "~1:1 square"
    sample-alts:
      - "flux-2-flex"
      - "gpt-image-2"
      - "gpt-image-1.5"
  thumbnail:
    count: 16
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "black-forest-labs"
      - "openai"
      - "openai"
```

**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 `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:*

- **2 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.
