narrative: |
  neon.tech is built on a soft, near-white canvas (rgb(228, 241, 235)).
  The system uses rgb(255, 255, 255) as the singular interactive color.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Inter as the primary typeface.
  Inter is paired with Inter Fallback for secondary roles.
  Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model.
  Motion is a first-class concern — 5 keyframe animations plus transition-driven interactions.

# Design System — neon.tech
> Extracted automatically by Prism from https://neon.tech
> Date: 2026-06-11
> Viewport: Desktop 1440x900 + Mobile 390x844
> Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted).


## 0. Design DNA

**Density**: moderate  |  **Motion**: animated  |  **Weight**: light  |  **Aesthetic**: sharp-architectural

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#e4f1eb` |
| Type posture | sans-led (Inter) | "The world's most advanced back" |
| Color assertion | dual-accent | #ffffff |
| Whitespace | moderate | section rhythm 54px |
| Interaction | animated | 5 keyframes, 9 transitions |
| Radius language | 0px-architectural | from token scale |

**Prism fingerprint**: `neutral-canvas · sans-display · dual-accent · 0px-architectural · animated-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(228, 241, 235)` is the page background. Every component composits against this.
> - **Accent**: `rgb(255, 255, 255)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 54px between major bands. Card padding: 32px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
> - **Forbidden**: Do NOT introduce heavy box-shadows — this system relies on borders for separation
>
> **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

neon.tech sits on a light gray canvas (`#e4f1eb`), a neutral foundation calibrated for sustained reading and component contrast. 

Typography is anchored in **Inter**. Negative letter-spacing at display sizes (-2.72px at 68px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Pure White (`#ffffff`). **Pure White** (`#ffffff`) provides interactive distinction without visual aggression. Shadow is absent by design — depth is conveyed through borders, spacing, and color differentiation rather than light simulation. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Light Gray (`#e4f1eb`)
- Primary typeface: IBM Plex Sans
- Primary text: Pure White (`#ffffff`)
- Accent: Pure White (`#ffffff`)
- Display: 68px weight 400, letter-spacing -2.72px
- Custom fonts loaded: IBM Plex Sans, IBM Plex Sans Fallback, GeistMono, Inter, Inter Fallback, esbuild, esbuild Fallback

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative


*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: "rgb(255, 255, 255)"
    focus:
      bg: "transparent"
      fg: "inherit"
  link:
    default:
      bg: "rgb(24, 25, 27)"
      fg: "rgb(255, 255, 255)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
```

**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
- **4 shape(s)** in this system: `Ghost`, `Dark / Solid`, `Outline`, `Light / Invert`
- **DO NOT introduce new buttons variants** without justification

## 5. Layout Principles

### Layout Type
**hero + sections**

### Grid
Flexbox column

### Max Width
1200px

### Spacing System
Generous spacing — editorial breathing room

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 10px |
| md | 14px |
| base | 20px |
| lg | 32px |
| xl | 46px |
| 2xl | 54px |
| 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 | `4px` |
| Page Body | `0px` |
| Navigation | `0px` |

**Shape Personality**: Subtly Rounded — Minimal corner rounding (1–4px). Professional restraint.

**Full Radius Spectrum**: 4px, 7px (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~120px internal vertical padding (up to 200px) — **very airy / premium**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone.

*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** | `46px` | Between major bands (color change, content shift) |
| **subsection** | `32px` | Within a section, between content groups |
| **card** | `14px` | Card padding, list-item spacing |
| **compact** | `10px` | 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:** "Neon is the Postgres backenddesigned for apps and agents." — 68px left-aligned
- **Subheading:** "S3-compatible object storage that branches with your projects."
- **Media:** present, positioned top
- **CTAs:** 2 (primary: "Get started")
- **Clone instruction:** Reproduce the **centered** layout. Use the heading font-size token at the documented size. Place media top of text.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 23px
- **Logo:** ✓ present
- **Nav links:** 26 primary items
- **CTAs in nav:** 1
- **Clone instruction:** Build a static unknown navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Card count:** 6 cards detected
- **Columns (desktop):** 5-up grid
- **Card dimensions:** 299×123px (aspect 2.43:1)
- **Gap:** 64px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 5-column grid (desktop) with cards at ~2.43:1 aspect ratio. Each card has an image at the top.

### Testimonial Pattern

- **Count:** 1 testimonial blocks
- **Layout:** single-feature
- **Avg quote length:** 286 chars (long-form story)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
- **Clone instruction:** Build a single-feature of 1 testimonials.   

### CTA Banner Pattern

- **Banner count:** 2
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Avoid incidents"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.

### Footer Pattern

- **Columns:** 1
- **Links:** 34 total
- **Height:** 340px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~34 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 |

**Shadow Philosophy**: Flat design — no shadows used. Borders and spacing define structure.

## 7. Motion & Interaction

### Easing System

| CSS Variable | Curve | Semantic Name |
|--------------|-------|---------------|
| `--ease-in-out` | `cubic-bezier(.4, 0, .2, 1)` | Ease Out — Decelerating |
| `--default-transition-timing-function` | `cubic-bezier(.4, 0, .2, 1)` | Ease Out — Decelerating |
| `--ease-in` | `cubic-bezier(.4, 0, 1, 1)` | Custom Ease — Balanced |

### Duration Scale

| CSS Variable | Value | Tier |
|--------------|-------|------|
| `--default-transition-duration` | `.15s` | Fast |

### Copy-Paste Transition Snippets

**Color / Background**
```css
transition: color 0.2s cubic-bezier(0.4, 0, 0.2, 1), background-color 0.2s cubic-bezier(0.4, 0, 0.2, 1), border-color 0.2s cubic-...;
```

**All Props**
```css
transition: 0.2s cubic-bezier(0.4, 0, 0.2, 1);
```

**All Props**
```css
transition: height 0.3s cubic-bezier(0.4, 0, 0.2, 1);
```

**All Props**
```css
transition: 0.3s cubic-bezier(0.4, 0, 0.2, 1);
```

### Keyframe Animation Catalog

| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `lineAnimation` | Slide | transform | UI transition |
| `shimmer` | Slide | transform | Loading placeholder |
| `spin` | Rotate / Spin | transform | Loading indicator |
| `text-blink` | Color Pulse | color, text-shadow | Attention / status |
| `logoMove` | Slide | transform | UI transition |

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `200ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 5 unique animations (5 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 Light Gray (`#e4f1eb`) as the page background — it's intentionally not pure white
- Use Inter as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-2.72px) at display sizes for compressed, editorial headlines
- Use Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color
- Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
- Respect the 4px–46px 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
- Use a 5-column grid on desktop — density matters for this content type
- Repeat the primary CTA across 2 banner sections — conversion paths are layered, not single

### Don't
- Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity
- 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 introduce additional saturated accent colors — the palette is intentionally controlled
- Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
- 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(228, 241, 235)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(228, 241, 235)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(255, 255, 255)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(255, 255, 255)\"]').length <= 3 per fold"
  - id: brand-depth-001
    type: dont
    rule: "Do NOT introduce drop shadows on cards or sections"
    why: "Containment is achieved via borders, not elevation — adding shadows breaks the depth contract"
    test: "getComputedStyle(card).boxShadow === 'none'"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 413px | Single column, compact spacing |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1023px | Multi-column grids begin |
| Desktop | 1279px | Full feature layout |
| Large Desktop | 1366px | Maximum content width |
| Ultra-wide | 1599px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `68px` | `28px` |
| heading | line-height | `76.5px` | `31.5px` |
| heading | letter-spacing | `-2.72px` | `-1.12px` |
| nav | display | `block` | `none` |
| nav | height | `22.5px` | `auto` |
| hero | height | `1011px` | `704px` |
| button | padding | `0px 14px` | `0px 10px` |
| button | width | `99.9531px` | `auto` |

### Collapsing Strategy
- Headlines: 68px → 28px 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 14px 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):

- **Card grid: 5-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.


## 7c. Visual Effects & Dynamic Behavior

*The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.*

- **Canvas / 2D rendering** — animated/interactive canvas (charts, graphs, particle fields). Reproduce as live data-viz (e.g. an animated SVG/Canvas line chart), NOT a static image.
- **Clip-path shapes** — 8 non-rectangular cut(s).

> **Motion fingerprint**: Canvas 2D, non-rectangular shapes (10)

## 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://neon.com/images/social-previews/index.jpg?updated=2026-05-27
  *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: 2.31:1 (ultra-wide cinematic)
- Rendered size: 1920×832px
- *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): 3 (27%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 6 (55%)
- Ultra-wide (>2.3): 2 (18%)

**Media Format Mix:**
- SVG: 6 (icons, illustrations, decorative geometry)

**Average rendered image size:** 652×373px
**Above-fold image count:** 3 / 11

**Decorative Patterns Detected:**
- 1 multi-stop linear gradient (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 7 background patterns (non-photo url() backgrounds) — textures/illustrations as backdrops
- **Noise/grain texture** detected — adds tactile film grain to flat backgrounds

**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: Light Gray (`#e4f1eb`)
- Primary text: Pure White (`#ffffff`)
- Accent: Pure White (`#ffffff`)
- Border: Charcoal (`#303236`)
- Font: Inter
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Light Gray background (#e4f1eb). Headline at 68px Inter weight 400, line-height 1.13, letter-spacing -2.72px, color #ffffff."
- "Create the primary CTA button: `#ffffff` background, `#ffffff` text, 4px border-radius, 0px 14px padding, 500 weight, Inter font."
- "Build navigation: static on `#e4f1eb`. Inter 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Light Gray (`#e4f1eb`) — every component is composited against this exact base.
2. **Typography**: All type in Inter, weight range 300–800. Never exceed 800 — heavier weights break the brand's tonal restraint.
3. **Accent**: Pure White (`#ffffff`) is the sole interactive color. On hover → #34d59a (`#34d59a`). 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`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (4px–46px). 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.*

**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:
    - "Cloud primitives for the AI Engineering era. Integrate with a single command and the LLM does the ha"
    - "Advanced autoscaling. Keep scaling without worrying about capacity. Never overpay for resources you"
    - "Speed and scale for agents. And devs."
    - "Trusted Postgres, Backed by Giants. Neon was founded by Postgres committers, bringing decades of exp"
  sub-headings:
    - "Copy-on-write"
    - "Deploy thousands of databases that turn off when idle. Inactive databases pause on their own, keepin"
    - "Database checkpoints. Copy-on-write storage makes it cheap and fast to save point-in-time versions o"
    - "12,000,000"
  ctas:
    - "Product"
    - "What is Neon Serverless Postgres, by Databricks"
    - "Log in"
    - "Sign up"
    - "Get started"
    - "Read the docs"
    - "AI"
    - "$ npx neonctl init"
  navigation:
    - "Neon"
    - "Discord"
    - "22.2k"
    - "Docs"
    - "Pricing"
    - "Autoscaling Automatic instance sizing"
    - "Serverless App Autoscale with traffic"
    - "Multi-TB Scale and restore instantly"
    - "Platforms Offer Postgres for your users"
    - "Dev/Tests Production-like environment"
  footer-links:
    - "Neon"
    - "Neon status loading..."
    - "Apache Software Foundation"
    - "Privacy Notice"
    - "About"
    - "Discord"
    - "CCPA Compliant"
    - "Compliance Guide"
```

**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: 2
    avg-ratio: 2.17
    common-aspect: "~16:9 landscape"
  product:
    count: 2
    avg-ratio: 1.05
    common-aspect: "~1:1 square"
  thumbnail:
    count: 24
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Databricks logo"
```

**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">
  All paid plans now include 5x more free data transfer: 500 GB per month, up from 100 GB. Read the de
</button>
```
_Source pattern detected: padding `10px 0px` · radius `0px` · weight `400`_

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


## 17. Content Architecture & Resources (Links by Purpose)

*The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.*

**By purpose:** **nav** 27 · **cta** 2 · **auth** 1 · **blog** 1 · **social** 3 · **legal** 4 · **footer** 12 · **other** 10

**Primary actions (conversion path):**
- Account access — "Log in" (login/signup) → `https://neon.tech/unify?a=3c952cba-e5ea-4bdb-9268-eeff0758d95a&n=login`
- Primary call-to-action — "Sign up" (the conversion path) → `https://neon.tech/unify?a=3c952cba-e5ea-4bdb-9268-eeff0758d95a&n=signup`
- Primary call-to-action — "Get started" (the conversion path) → `https://neon.tech/unify?a=3c952cba-e5ea-4bdb-9268-eeff0758d95a&n=signup`

**Signals:** 9/60 links carry a featured image · dominant link roles: navigation (27), footer-link (16), inline-link (8).

## 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.

*Auto-detected extraction limitations — understand before building:*

- **Licensed web fonts (IBM Plex Sans, GeistMono, Inter)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).
- **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.

| 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 | 112 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 9 typography roles inferred |
| §4 Components | Low | 1 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 17 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 11 images, hero present |

### Hover State CSS (Intercepted)

**1 hover rule lines** captured from CSS files. Key interactive transitions from real CSS (not inferred):

```css
@media (hover:hover){.admonition-text a:hover{text-decoration-color:#000}

@media (hover:hover){.admonition-text a:is(.dark *):hover{text-decoration-color:#fff}

@media (hover:hover){.ais-SearchBox-input:hover{--tw-shadow:0 0 #0000;box-shadow:var(--tw-inset-shadow), var(--tw-inset-ring-shadow), var(--tw-ring-offset-shadow), var(--tw-ring-shadow), var(--tw-shadow);border-color:#afb1b6}

@media (hover:hover){.ais-SearchBox-input:is(.dark *):hover{border-color:#494b50}
```

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 5449 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**9 breakpoints** read from the live `@media` rules (not guessed):
`413px` · `767px` · `1023px` · `1279px` · `1280px` · `1366px` · `1599px` · `1919px` · `1921px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×4537 · `20px`×293 · `14px`×135 · `15px`×127 · `12px`×102 · `18px`×100 · `13px`×74 · `10px`×20

**Radius scale** (× = paint count): `4px`×121 · `100%`×1 · `8px`×1

**Weights** (× = paint count): `400`×5253 · `500`×185 · `600`×6 · `300`×4

**Layout gaps** (× = paint count): `8px normal`×50 · `12px`×30 · `3px`×30 · `normal 10px`×18 · `8px`×16 · `normal 4px`×10 · `normal 12px`×9 · `normal 128px`×8

**Elevation (real shadows)**:
```css
rgba(0, 0, 0, 0.4) 0px 8px 20px 0px
rgba(0, 0, 0, 0.1) 0px 14px 20px 0px
```

### Provenance — measured styles on key elements
Read from the live CSSOM (includes runtime-injected CSS). This is *what actually styles the page*, by element:

```css
body { font-family:var(--font-inter), ui-sans-serif, system-ui, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; color:#1a1a1a; background-color:#fff }
body { color:#fff; background-color:#000 }
header { background-color:#fff }
header { background-color:#000 }
h1 { font-size:68px }
h2 { font-size:48px }
h2 { font-weight:var(--font-weight-normal) }
h2 { color:#797d86 }
button { border-radius:var(--radius-sm) }
button { font-size:15px }
button { font-weight:var(--font-weight-normal) }
a { background-color:#ebf5f0 }
```

> Selectors normalised to their semantic element — source class names are often build-hashed (`.bgDIHX`) and not reusable. The declarations + CSS vars are the transferable part.
