narrative: |
  superhuman.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(212, 199, 255) as the singular interactive color.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Super Sans VF as the primary typeface.

> **🤖 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(212, 199, 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

superhuman.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 **Super Sans VF**. 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 Warm Brown (`#292827`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Lavender** (`#d4c7ff`) 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: Pure White (`#ffffff`)
- Primary typeface: Super Sans VF
- Primary text: Warm Brown (`#292827`)
- Accent: Lavender (`#d4c7ff`)
- Display: 64px weight 540
- Shadow system: 6 distinct elevation levels
- Custom fonts loaded: Super Sans VF, Super Serif VF, Super Sans Mono VF

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Button**:
  - **hover:** text #000000 → #ffffff, border changes
- **NavLink**:
  - **hover:** text #000000 → #000000, border changes

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

```yaml
component-behaviors:
  button:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "color(srgb 1 1 1 / 0.95)"
    hover:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
    focus:
      bg: "rgba(0, 0, 0, 0)"
      fg: "color(srgb 1 1 1 / 0.95)"
  link:
    default:
      bg: "rgb(66, 29, 36)"
      fg: "rgb(255, 255, 255)"
  card:
    default:
      bg: "rgba(0, 0, 0, 0)"

    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(41, 40, 39)"
```

**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
- **6 shape(s)** in this system: `Ghost`, `Ghost`, `Secondary`, `Outline`, `Icon Button`
- **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

### CTA Banners
- **1 shape(s)** in this system: `Full-width CTA`
- **DO NOT introduce new cta banners variants** without justification

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
1280px

### 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 | 8px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 12px | Cards, containers |
| Lg | 16px | Large rounded elements, pill segments |
| Xl | 24px | Category strips, featured containers |
| Full | 999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `16px` |
| Navigation | `none` |
| CTA Banners | `0px` |
| Page Body | `0px` |

**Shape Personality**: Generously Rounded — Soft, friendly corners (8px+). Approachable, consumer-facing feel.

**Full Radius Spectrum**: 8px, 12px, 16px, 24px, 999px (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).

**4/8 structural patterns detected.**

### Hero Pattern

- **Composition:** centered — Centered composition — heading + subheading + CTAs stacked vertically, content centered horizontally. Common for SaaS marketing pages.
- **Viewport coverage:** 123px tall (not full-viewport)
- **Heading:** "Superpowers, everywhere you work" — 64px center-aligned
- **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.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 42px
- **Logo:** ✗ absent
- **Nav links:** 3 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:** 4 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1310×669px (aspect 1.96:1)
- **Gap:** 36px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.96:1 aspect ratio. Each card has an image at the top.

### CTA Banner Pattern

- **Banner count:** 2
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background✓ gradient fill
- **Primary CTA text:** "Read our announcement"
- **Clone instruction:** Place multiple CTA banners across page sections. Use gradient background.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Subtle (Level 1) | `color(srgb 0.278431 0.270588 0.262745 / 0.16) 0px -4px 8px 0.5px` | Cards, dividers, borders |
| Layered (Level 2) | <br>`color(srgb 0.0784314 0.0784314 0.0745098 / 0.24) 0px 1px 2px 0px`,<br>`rgb(53, 48, 136) 0px 0px 0px 1px` | Cards, elevated surfaces |
| Subtle (Level 3) | `color(srgb 0.0784314 0.0784314 0.0745098 / 0.08) 0px 1px 2px 0px` | Cards, dividers, borders |
| Layered (Level 4) | <br>`rgb(255, 255, 255) 0px -5px 0px 0px`,<br>`rgb(255, 255, 255) 0px 5px 0px 0px` | Cards, elevated surfaces |

**Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation.

### Elevation Scale (CSS Tokens)

| Level | Shadow Value |
|-------|-------------|
| xsmall | `0 0 0 1px rgb(from light-dark(#474543,#141413) r g b/4%),0 4px 8px -2px rgb(from light-...` |
| small | `0 0 0 1px rgb(from light-dark(#474543,#141413) r g b/4%),0 16px 8px -8px rgb(from light...` |
| medium | `0 0 0 1px rgb(from light-dark(#474543,#141413) r g b/4%),0 1px 1px 0.5px rgb(from light...` |
| large | `0 0 0 1px rgb(from light-dark(#474543,#141413) r g b/4%),0 1px 1px 0.5px rgb(from light...` |

## 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

| CSS Variable | Value | Tier |
|--------------|-------|------|
| `--motion-duration-fast` | `100ms` | Fast |
| `--motion-duration-base` | `200ms` | Normal |
| `--motion-duration-emphasis` | `400ms` | Slow |
| `--motion-duration-slow` | `300ms` | Normal |

### Copy-Paste Transition Snippets

**Opacity**
```css
transition: opacity 1s ease-in-out;
```

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: symmetric in-out (precise)

> 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 Warm Brown (`#292827`) for text — not pure black, it's warmer and more readable
- Use Super Sans VF 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 Lavender (`#d4c7ff`) 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
- Apply 16px padding inside cards — matches the design system's content breathing room
- Use 16px border-radius on cards — consistent with the grid card corners
- Maintain nav height at 42px — 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
- Each card includes a top image — imagery is part of the card identity, not optional
- Repeat the primary CTA across 2 banner sections — conversion paths are layered, not single

### 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 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
- 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 `rgb(212, 199, 255)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(212, 199, 255)\"]').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 | `64px` | `32px` |
| heading | line-height | `61.44px` | `30.72px` |
| nav | display | `block` | `none` |
| nav | height | `42px` | `auto` |
| button | width | `90px` | `100%` |
| card | width | `360px` | `auto` |

### Collapsing Strategy
- Headlines: 64px → 32px on mobile
- Navigation: block → none on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 0px 8px 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):

*No major structural differences detected between desktop and mobile widgets. The same blueprints scale rather than collapse — verify by inspecting actual mobile render.*

## 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://superhumanstatic.com/super-funnel/main/public/images/v3/social-share.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: 1.25:1 (landscape)
- Rendered size: 822×660px
- Alt text: "Person thinking"
- *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): 2 (22%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)
- Ultra-wide (>2.3): 7 (78%)

**Media Format Mix:**
- WebP: 3 (optimized photo/illustration hybrid)
- SVG: 7 (icons, illustrations, decorative geometry)

**Average rendered image size:** 472×242px
**Above-fold image count:** 1 / 9

**Decorative Patterns Detected:**
- 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 1 large decorative SVG shape (≥200×200px, non-icon) — likely blob/illustration accents

**Clone instruction for decorative work:** Decorative details are subtle — don't over-style; the design relies on restraint.

**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: Pure White (`#ffffff`)
- Primary text: Warm Brown (`#292827`)
- Accent: Lavender (`#d4c7ff`)
- Border: Warm Brown (`#292827`)
- Font: Super Sans VF
- Body: 16px weight 460

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 64px Super Sans VF weight 540, line-height 0.96, color #292827."
- "Create the primary CTA button: `#d4c7ff` background, `#000000` text, 999px border-radius, 0px 8px padding, 460 weight, Super Sans VF font."
- "Design a card on `transparent` background. Border: none. Radius: 16px. Shadow: none. Padding: 16px."
- "Build navigation: static on `#ffffff`. Super Sans VF 16px weight 460 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 Super Sans VF, weight range 200–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Lavender (`#d4c7ff`) is the sole interactive color. On hover → Slate Blue (`#714cb6`). Use CSS transitions, not opacity/brightness filters.
4. **Shape**: CTAs at `0px`, cards at `16px`. 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:
    - "Mail, Docs, and AI that works in every app and tab"
    - "Your Superhuman suite"
    - "Mail"
    - "The most productive email app ever made"
    - "Becoming Superhuman."
    - "AI that works everywhere you work"
  sub-headings:
    - "Builders of Superhuman Platform apps"
    - "Products"
  ctas:
    - "Product"
    - "Contact sales"
    - "Sign up"
    - "Get Superhuman"
    - "Get the suite"
    - "Mail"
    - "Go"
    - "Read our announcement"
  navigation:
    - "Enterprise"
    - "Education"
    - "Pricing"
    - "Contact sales"
    - "Log in"
    - "Sign up"
    - "Superhuman Go"
    - "Grammarly"
    - "Coda"
    - "Superhuman Mail"
  footer-links:
    - "Superhuman Go"
    - "Customer Business Agreement"
```

**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:
  hero:
    count: 1
    avg-ratio: 3.00
    common-aspect: "~16:6 banner"
    sample-alts:
      - "Tonal Flower"
```

**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 `0px 8px` · radius `0px` · weight `460`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `16px` · radius `16px` · 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:*

- **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.
- **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.

## 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 |
|----------|----------------|-------------------|
| **Keyframe animations** | No @keyframes declarations found (transitions only) | Use CSS transitions for state changes; avoid complex scroll-based animations |
