description: "Dark-canvas product system built on #191918 with #62aef0 as the single brand accent. Type anchored in NotionInter at 64px / weight 700. Extracted automatically from https://notion.so/ — every value from getComputedStyle(), no approximation."
narrative: |
  notion.so is built on a near-black canvas (rgb(25, 25, 24)).
  The system uses #62aef0 as the accent for primary actions and brand signals.
  Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside NotionInter as the primary typeface.

# Design System — notion.so
> Extracted automatically by Clone Architect from https://notion.so
> 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(25, 25, 24)` is the page background. Every component composits against this.
> - **Accent**: `#62aef0` 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

notion.so commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a dark surface (`#191918`) where surfaces are layered through stepped luminance — each elevated level is slightly less dark than the one beneath it, creating depth without color shifts. 

Typography is anchored in **NotionInter**, deployed with OpenType features enabled globally (`"lnum", "locl" 0`). These aren't decorative — they're load-bearing: without them, the typeface reverts to its generic state and the design loses its specific texture. 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. Negative letter-spacing at display sizes (-2.125px at 64px) compresses headlines into engineered blocks, dense and authoritative. 

Body text reads in Banner (`#ffffff`). **Cornflower Blue** (`#62aef0`) 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. 
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Near Black (`#191918`)
- Primary typeface: NotionInter
- Primary text: Banner (`#ffffff`)
- Accent: Cornflower Blue (`#62aef0`)
- Display: 64px weight 700, letter-spacing -2.125px
- Shadow system: 7 distinct elevation levels
- Custom fonts loaded: NotionInter, Lyon Text, iA Writer Mono, Permanent Marker

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | NotionInter | 64px | 700 | 1 | -2.125px | Main headline (h1) |
| Input Large | NotionInter | 42px | 700 | 1.14 | -1.5px | Form input (42px) |
| Caption / Badge | NotionInter | 22px | 700 | 1.27 | -0.25px | small text (22px) |
| Card Title | NotionInter | 16px | 400 | 1.5 | normal | Card headings |
| Button Large | NotionInter | 16px | 500 | 1.5 | normal | Button label (16px) |
| Sub-heading | NotionInter | 14px | 400 | 1.43 | normal | Third-level heading (h3) |
| Caption / Badge | NotionInter | 14px | 500 | 1.43 | normal | small text (14px) |
| Caption | NotionInter | 12px | 500 | 1.33 | 0.125px | Image caption, helper text |

### Font Weight Scale

CSS custom properties define 8 explicit weight steps:
- `--font-weight-regular`: `400` — Regular
- `--font-weight-variable-regular`: `420` — Regular (custom, ~400)
- `--font-weight-medium`: `500` — Medium
- `--font-weight-variable-medium`: `520` — Medium (custom, ~500)
- `--font-weight-semibold`: `600` — SemiBold
- `--font-weight-variable-semibold`: `620` — SemiBold (custom, ~600)
- `--font-weight-variable-bold`: `680` — Bold (custom, ~700)
- `--font-weight-bold`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `64px`, `54px`, `48px`, `42px`, `40px`, `32px`, `26px`, `24px`, `22px`, `20px`, `16px`, `15px`, `14px`, `12px`

> 8 size(s) detected outside the sampled hierarchy (54px, 48px, 40px, 32px, 26px, 24px, 20px, 15px). 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:

- **lining figures** (`lnum`) — full-height numbers, more authoritative than old-style
- **case-sensitive forms** (`case`) — punctuation height adjusted for uppercase contexts
- **capital spacing** (`cpsp`) — added tracking on uppercase for breathing room
- **localized forms** (`locl`) — glyphs swapped based on script/locale

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

## 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 | 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 | `4px` |
| Cards & Containers | `0px` |
| Navigation | `none` |
| CTA Banners | `0px` |
| Testimonials | `12px` |
| Tabs | `0px` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 0px, 4px, 5px, 8px, 12px, 16px, 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).

**7/8 structural patterns detected.**

### Hero Pattern

- **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages.
- **Viewport coverage:** 256px tall (not full-viewport)
- **Heading:** "Meet the night shift." — 64px center-aligned
- **Subheading:** "Notion agents keep work moving 24/7. They capture knowledge, answer questions, and push projects forward—all while you sleep."
- **CTAs:** 2 (primary: "Get Notion free")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. No imagery needed for hero — text-driven.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 64px
- **Logo:** ✓ present
- **Nav links:** 5 primary items
- **CTAs in nav:** 1
- **Theme toggle:** ✓ dark/light mode switcher present
- **Clone instruction:** Build a static unknown navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Layout:** grid
- **Avg quote length:** 81 chars (medium quote)
- **Includes:** ✓ avatars | ✓ company logos | ✓ star ratings
- **Clone instruction:** Build a grid of 12 testimonials. Each includes an avatar. Include source company logos. Display ratings prominently.

### CTA Banner Pattern

- **Banner count:** 1
- **Position:** mid-page
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Q&A agentsAnswers questions instantly using knowledge you al"
- **Clone instruction:** Place a single CTA banner mid-page. Use contrasting solid background.

### Footer Pattern

- **Columns:** 1
- **Links:** 28 total
- **Height:** 416px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~28 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 |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0) 0px 1px 0px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.01) 0px 0.175px 1.041px 0px`,<br>`rgba(0, 0, 0, 0.02) 0px 0.8px 2.925px 0px`,<br>`rgba(0, 0, 0, 0.027) 0px 2.025px 7.847px 0px`,<br>`rgba(0, 0, 0, 0.04) 0px 4px 18px 0px` | Cards, elevated surfaces |
| Layered (Level 3) | <br>`rgba(255, 255, 255, 0.2) 0px 0px 20px 5px` | Cards, elevated surfaces |
| Layered (Level 4) | <br>`rgba(0, 0, 0, 0.01) 0px 0.667px 3.502px 0px`,<br>`rgba(0, 0, 0, 0.016) 0px 2.933px 7.252px 0px`,<br>`rgba(0, 0, 0, 0.02) 0px 7.2px 14.462px 0px`,<br>`rgba(0, 0, 0, 0.024) 0px 13.867px 28.348px 0px`,<br>`rgba(0, 0, 0, 0.03) 0px 23.333px 52.123px 0px`,<br>`rgba(0, 0, 0, 0.04) 0px 36px 89px 0px` | 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**: Balanced Pacing (median duration: `200ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 39 unique animations (39 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 dark background (`#191918`) as the foundation — this is a dark-mode-native design
- Use NotionInter as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-2.125px) at display sizes for compressed, editorial headlines
- 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 Accent (`#62aef0`) 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
- 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
- Keep the hero centered and text-driven — no decorative media, typography carries the message
- Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Include a theme toggle in the nav — dark mode is a first-class feature
- 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 (12+ items) — quantity signals scale and trust

### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't substitute with generic sans-serif or serif — the custom font carries the brand
- Don't increase letter-spacing on headings — the type is designed to run tight at scale
- 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 collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't add hero illustrations or photos — they'll break the typographic restraint
- Don't make the nav sticky — this design lets it scroll away to maximize content focus


## 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(25, 25, 24)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(25, 25, 24)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `#62aef0` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"#62aef0\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 375px | Single column, compact spacing |
| Tablet | 768px | Multi-column grids begin |
| Desktop | 1032px | Full feature layout |
| Desktop | 1120px | Full feature layout |
| Desktop | 1280px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `64px` | `54px` |
| heading | line-height | `64px` | `56px` |
| heading | letter-spacing | `-2.125px` | `-1.875px` |
| button | width | `90.3906px` | `auto` |
| card | width | `436.062px` | `310px` |

### Collapsing Strategy
- Headlines: 64px → 54px 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: 5px 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):

- **Navigation collapses to hamburger** — 5 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://www.notion.com/front-static/meta/custom-agents-og.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: 1.19:1 (landscape)
- Rendered size: 192×161px
- *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): 6 (29%)
- Portrait (<0.87): 3 (14%)
- Square (0.87–1.15): 9 (43%)
- Ultra-wide (>2.3): 3 (14%)

**Media Format Mix:**
- SVG: 3 (icons, illustrations, decorative geometry)

**Average rendered image size:** 301×235px
**Above-fold image count:** 6 / 21

**Decorative Patterns Detected:**
- 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 2 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:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces.

**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: Near Black (`#191918`)
- Primary text: Banner (`#ffffff`)
- Accent: Cornflower Blue (`#62aef0`)
- Border: Dim Gray (`#615d59`)
- Font: NotionInter
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Near Black background (#191918). Headline at 64px NotionInter weight 700, line-height 1, letter-spacing -2.125px, color #ffffff."
- "Create the primary CTA button: `#62aef0` background, `#ffffff` text, 8px border-radius, 4px 14px padding, 500 weight, NotionInter font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: relative on `#191918`. NotionInter 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Near Black (`#191918`) — every component is composited against this exact base.
2. **Typography**: All type in NotionInter, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Cornflower Blue (`#62aef0`) is the sole interactive color. On hover → Accent Strong (`#097fe8`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.45,0,0.55,1)`. Timing: 100ms for micro-interactions, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `4px`, 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:
    - "Keep work moving 24/7."
    - "Automate repetitive work for your team."
    - "You assign the tasks. Notion Agent does the work."
    - "One search for everything."
    - "More productivity. Fewer tools."
  sub-headings:
    - "See what Custom Agents can do"
    - "Triage product feedback→"
    - "Create your own Custom Agent→"
    - "Get started on Notion"
  ctas:
    - "Product"
    - "Get Notion free"
    - "Request a demo"
    - "Pause"
  navigation:
    - "Developers"
    - "Enterprise"
    - "Pricing"
    - "Request a demo"
    - "Get Notion free"
    - "Log in"
  footer-links:
    - "About us"
```

**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: 16
    avg-ratio: 3.43
    common-aspect: "~16:6 banner"
    sample-alts:
      - "OpenAI"
      - "Figma"
      - "Ramp"
  product:
    count: 3
    avg-ratio: 1.12
    common-aspect: "~1:1 square"
    sample-alts:
      - "Homepage | Agents 26 | Bento | Agent | Front | Desktop"
      - "Homepage | Agents 26 | Bento | Search | Desktop"
  thumbnail:
    count: 23
    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">
  Product
</button>
```
_Source pattern detected: padding `5px 10px` · radius `4px` · weight `400`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `24px` · radius `12px` · shadow `none`_

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

## Extraction Completeness: 95/100 (A)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 25 | 25 | 18 named colors |
| Typography | 20 | 20 | 8 roles defined |
| Components | 20 | 20 | 6 specs extracted |
| Motion & Interaction | 15 | 15 | Keyframes present, easing vars |
| CSS Custom Properties | 10 | 10 | 799 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 |
|----------|----------------|-------------------|
| **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 | 799 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 8 typography roles inferred |
| §4 Components | High | 6 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 24 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 21 images, hero present |
