description: "Light product system built on #fcfbf8 with #4b73ff as the primary CTA accent. Type anchored in Camera Plain Variable at 20px / weight 400. Extracted automatically from https://lovable.dev/ — every value from getComputedStyle(), no approximation."
narrative: |
  lovable.dev is built on a warm, off-white canvas (rgb(252, 251, 248)).
  The system uses rgb(75, 115, 255) as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Camera Plain Variable as the primary typeface.

# Design System — lovable.dev
> Extracted automatically by Clone Architect from https://lovable.dev
> 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(252, 251, 248)` is the page background. Every component composits against this.
> - **Accent**: `rgb(75, 115, 255)` 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**: 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

lovable.dev's canvas is a warm, intentionally-tinted surface (`#fcfbf8`) — a refusal of the default white that immediately signals editorial intent. This isn't sterility, it's an invitation to read. 

Typography is anchored in **Camera Plain Variable**. The weight scale rejects the standard 100/200/.../900 ladder in favor of custom values (max **700** in this system) — a deliberate signal that this design system is precisely tuned, not assembled from defaults. 

Body text reads in Near Black (`#1c1c1c`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Ring Blue** (`#4b73ff`) 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: Cream (`#fcfbf8`)
- Primary typeface: Roboto Mono Variable
- Primary text: Near Black (`#1c1c1c`)
- Accent: Ring Blue (`#4b73ff`)
- Shadow system: 11 distinct elevation levels
- Custom fonts loaded: Roboto Mono Variable, Camera Plain Variable

## 3. Typography Rules

### Font Families
- **Primary**: `Camera Plain Variable`
- **Secondary**: `Roboto Mono Variable`

### Custom Fonts Loaded
- **Roboto Mono Variable** weight 100 700 (normal)
- **Camera Plain Variable** weight 100 900 (normal)
- **Camera Plain Variable** weight 400 (italic)

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Camera Plain Variable | 60px | 600 | 1.1 | -1.5px | Main headline (h2) |
| Section Heading | Camera Plain Variable | 48px | 600 | 1 | normal | Section titles (h2) |
| Sub-heading | Camera Plain Variable | 36px | 600 | 1.1 | -0.9px | Third-level heading (h3) |
| Card Title | Camera Plain Variable | 16px | 400 | 1.5 | normal | Card headings |
| Button | Camera Plain Variable | 15px | 400 | 1.6 | normal | Button label (15px) |
| Button | Camera Plain Variable | 14px | 400 | 1.5 | normal | Button label (14px) |
| Link | Camera Plain Variable | 14px | 480 | 1.5 | normal | Link (14px) — Decoration: none |

### Font Weight Scale

CSS custom properties define 4 explicit weight steps:
- `--font-weight-normal`: `400` — Regular
- `--font-weight-medium`: `480` — Medium (custom, ~500)
- `--font-weight-semibold`: `600` — SemiBold
- `--font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `60px`, `48px`, `36px`, `20px`, `18px`, `16px`, `15px`, `14px`

> 2 size(s) detected outside the sampled hierarchy (20px, 18px). 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";
}
```

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **NavLink**:
  - **hover:** text #1c1c1c → #000000
- **FooterLink**:
  - **hover:** transform applied

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

```yaml
component-behaviors:
  button:
    default:
      bg: "lab(0 0 0 / 0.88)"
      fg: "lab(98.2716 0 0)"
  link:
    default:
      bg: "rgb(28, 28, 28)"
      fg: "rgb(252, 251, 248)"
  card:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(28, 28, 28)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(28, 28, 28)"
    hover:
      bg: "rgba(0, 0, 0, 0)"
      fg: "oklab(0.226664 0.0000103414 0.00000451505)"

    hover:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(28, 28, 28)"
```

**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
- **5 shape(s)** in this system: `Ghost`, `Ghost`, `Icon Button`, `Icon Button`, `Light / Invert`
- **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

## 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 | 10px |
| base | 56px |
| lg | 24px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | calc(.5rem - 4px) | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 12px | Cards, containers |
| Lg | 16px | Large rounded elements, pill segments |
| Xl | 32px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `8px` |
| Cards & Containers | `0px` |
| Navigation | `none` |
| Page Body | `0px` |

**Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill.

**Full Radius Spectrum**: 6px, 7px, 8px, 12px, 16px, 24px, 28px, 32px (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** | `10px` | 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:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 32px
- **Logo:** ✗ absent
- **Nav links:** 4 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1120×496px (aspect 2.26:1)
- **Gap:** 160px between cards
- **Content:** ✓ image
- **Image position:** left
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~2.26:1 aspect ratio. Each card has an image at the left.

### Footer Pattern

- **Columns:** 5
- **Links:** 51 total
- **Height:** 601px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 5-column footer with ~10 links per column, social media links, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Subtle (Level 1) | `oklch(0.2 0 0 / 0.12) 0px 2px 2px -1px, oklch(0.2 0 0 / 0.12) 0px 4px 4px -2px` | Cards, dividers, borders |
| Inset (Level 2) | <br>`oklch(0.98 0.01 0 / 0.24) 0px 1px 0px 0px inset`,<br>`oklch(0.98 0.01 0) 0px -1px 0px 0px inset`,<br>`rgba(0, 0, 0, 0) 0px 0.5px 0px 0px inset`,<br>`rgba(0, 0, 0, 0) 0px -0.5px 0px 0px inset` | Buttons, pressed-state elements |
| Inset (Level 3) | <br>`rgb(0, 0, 0) 0px 0px 0px 0.5px inset` | Buttons, pressed-state elements |
| Inset (Level 4) | `oklch(1 0 0 / 0.08) 0px 0.5px 0px 0px inset, oklch(0 0 0 / 0.16) 0px -0.5px 0px 0px inset` | Buttons, pressed-state elements |

**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**: 38 unique animations (38 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 Cream (`#fcfbf8`) as the page background — it's intentionally not pure white
- Use Near Black (`#1c1c1c`) for text — not pure black, it's warmer and more readable
- Use Camera Plain Variable 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 (`#4b73ff`) as the primary accent — it's the brand's signature interactive color
- Use 8px border-radius on buttons — the standard corner rounding for interactive elements
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Each card includes a left image — imagery is part of the card identity, not optional
- Build a content-dense footer (5 columns, ~51 links) — this site treats the footer as a sitemap, not an afterthought

### Don't
- Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
- 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 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(252, 251, 248)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(252, 251, 248)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(75, 115, 255)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(75, 115, 255)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 600px | Expanded mobile layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | height | `32px` | `auto` |
| button | width | `auto` | `96px` |
| card | width | `262px` | `358px` |

### 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: 6px 10px 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:** 5 columns (desktop) → 2 columns (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://lovable.dev/img/opengraph-image.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: 0.99:1 (square / portrait)
- Rendered size: 2880×2904px
- *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): 8 (80%)
- Portrait (<0.87): 1 (10%)
- Square (0.87–1.15): 1 (10%)

**Media Format Mix:**
- WebP: 9 (optimized photo/illustration hybrid)
- PNG: 1 (logos, transparent UI elements, mockups)

**Average rendered image size:** 786×768px
**Above-fold image count:** 1 / 10

**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: Cream (`#fcfbf8`)
- Primary text: Near Black (`#1c1c1c`)
- Accent: Ring Blue (`#4b73ff`)
- Border: Dim Gray (`#5f5f5d`)
- Font: Camera Plain Variable
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Cream background (#fcfbf8). Headline at 20px Camera Plain Variable weight 400, line-height 1.5, color #1c1c1c."
- "Create the primary CTA button: `#4b73ff` background, `#000000` text, 8px border-radius, 6px 10px padding, 600 weight, Camera Plain Variable font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: relative on `#fcfbf8`. Camera Plain Variable 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Cream (`#fcfbf8`) — every component is composited against this exact base.
2. **Typography**: All type in Camera Plain Variable, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Ring Blue (`#4b73ff`) is the sole interactive color. On hover → Magenta (`#ff66f4`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Timing: 150ms for micro-interactions, 150ms for layout changes. 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.

## 11. CSS Design Tokens Raw Export

*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

```css
/* Colors */
:root {
  --ca-background: #fcfbf8;

## 13. Page Structure Skeleton

*The actual layout the source site uses. Reproduce these sections in order to match the site structure.*

```yaml
page-skeleton:
  - section: unknown
    tag: div
    classes: ["isolate", "flex", "min-h-0", "flex-1"]
    height: 4263px
    width: full-bleed
    layout: flex-column justify=normal
    children: 2
  - section: main-content
    tag: main
    height: 2964px
    width: full-bleed
    layout: block
    children: 2
  - section: section-4
    tag: section
    classes: ["relative", "flex", "w-full", "flex-col"]
    height: 900px
    width: full-bleed
    layout: flex-column justify=center
    children: 3
    padding: "180px 24px 216px"
  - section: section-5
    tag: section
    classes: ["mx-auto", "max-w-5xl", "py-20"]
    height: 255px
    width: 1024px
    layout: block
    children: 2
    padding: "80px 0px"
  - section: unknown
    tag: div
    classes: ["container"]
    height: 2064px
    width: 1280px
    layout: block
    children: 2
    padding: "0px 80px"
  - section: section-6
    tag: section
    height: 533px
    width: 1120px
    layout: block
    children: 2
  - section: section-7
    tag: section
    height: 552px
    width: 1120px
    layout: block
    children: 2
  - section: section-8
    tag: section
    height: 404px
    width: 1120px
    layout: block
    children: 2
  - section: footer
    tag: footer
    classes: ["border-muted-border", "bg-muted", "relative", "rounded-2xl"]
    height: 601px
    width: 1280px
    layout: block
    children: 1
    bg: "rgb(247, 244, 237)"
    padding: "56px"
  - section: unknown
    tag: div
    classes: ["container", "max-w-none", "2xl:max-w-screen-2xl"]
    height: 601px
    width: full-bleed
    layout: block
    children: 1
    padding: "0px 80px"
  - section: navigation
    tag: nav
    classes: ["grid", "grid-cols-2", "gap-x-8", "gap-y-12"]
    height: 487px
    width: 1166px
    layout: grid: 6-col gap=48px 32px
    children: 7
```

**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:
    - "Build something Lovable"
    - "Meet Lovable"
    - "Ready to build?"
  sub-headings:
    - "Start with an idea"
    - "Company"
  ctas:
    - "Solutions"
    - "Log in"
    - "Get started"
    - "Build"
    - "Send message"
    - "EN"
  navigation:
    - "Community"
    - "Enterprise"
    - "Pricing"
    - "Security"
    - "Careers"
    - "Press & media"
    - "Trust center"
    - "Partnerships"
    - "Student discount"
  footer-links:
    - "Careers"
    - "Do not sell or share my personal information"
```

**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:
```

**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">
  Solutions
</button>
```
_Source pattern detected: padding `4px 0px 4px 6px` · 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:*

- **Limited breakpoint data** — fewer than 3 media query breakpoints detected. The site may use fluid CSS (clamp/vw) or container queries for responsiveness rather than traditional breakpoints.
- **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass.

## 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 |
|----------|----------------|-------------------|
| **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 | 434 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 7 typography roles inferred |
| §4 Components | Medium | 3 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 | Medium | 1 breakpoints detected |
| §9b Photography | High | 10 images, hero present |
