narrative: |
  sanity.io is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(0, 82, 239) as the high-saturation accent for primary actions.
  Fully-rounded CTAs (9999px) signal a friendly, tactile interaction model alongside waldenburgNormal as the primary typeface.
  WaldenburgNormal is paired with waldenburgNormal Fallback for secondary roles.
  A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page.
  Motion is a first-class concern — 25 keyframe animations plus transition-driven interactions.

# Design System — sanity.io
> Extracted automatically by Prism from https://sanity.io
> 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**: expressive  |  **Weight**: light  |  **Aesthetic**: soft-rounded

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (waldenburgNormal) | "Structure powers intelligence" |
| Color assertion | dual-accent | #0052ef |
| Whitespace | moderate | section rhythm 48px |
| Interaction | expressive | 25 keyframes, 17 transitions |
| Radius language | soft-pill | from token scale |

**Prism fingerprint**: `neutral-canvas · sans-display · dual-accent · soft-pill · expressive-motion`

> **🤖 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(0, 82, 239)` 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

sanity.io uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. 

Typography is anchored in **waldenburgNormal**, deployed with OpenType features enabled globally (`"calt" 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. Negative letter-spacing at display sizes (-4.48px at 112px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Black (`#0b0b0b`) — softened from pure black, a small but deliberate detail that lowers reading friction. **#0052ef** (`#0052ef`) 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 comes from a small, deliberate set of shadows (2 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI. 
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: White (`#ffffff`)
- Primary typeface: ibmPlexMono
- Primary text: Black (`#0b0b0b`)
- Accent: #0052ef (`#0052ef`)
- Display: 112px weight 400, letter-spacing -4.48px
- Shadow system: 2 distinct elevation levels
- Custom fonts loaded: ibmPlexMono, ibmPlexMono Fallback, waldenburgNormal, waldenburgNormal Fallback

## 3. Typography Rules

### Font Families
- **Primary**: `waldenburgNormal`
- **Secondary**: `ibmPlexMono`
- **Font 3**: `ibmPlexMono Fallback`
- **Font 4**: `waldenburgNormal Fallback`

### Custom Fonts Loaded
- **ibmPlexMono** weight 400 (normal)
- **ibmPlexMono** weight 700 (normal)
- **ibmPlexMono Fallback** weight normal (normal)
- **waldenburgNormal** weight 400 (normal)
- **waldenburgNormal** weight 600 (normal)
- **waldenburgNormal Fallback** weight normal (normal)

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | waldenburgNormal | 112px | 400 | 1 | -4.48px | Main headline (h1) |
| Sub-heading | waldenburgNormal | 48px | 400 | 1.08 | -1.68px | Third-level heading (h3) |
| Body | waldenburgNormal | 16px | 400 | 1.5 | normal | Standard reading text |
| Input | waldenburgNormal | 15px | 400 | 1.5 | -0.15px | Form input (15px) |
| Button | ibmPlexMono | 13px | 400 | 1.5 | normal | Button label (13px) |
| Link | waldenburgNormal | 13px | 400 | 1.5 | normal | Link (13px) — Decoration: underline |
| Tiny / Micro | ibmPlexMono | 10px | 400 | 1.4 | normal | uppercase, small text (10px) |

### Font Weight Scale

CSS custom properties define 4 explicit weight steps:
- `--label-font-weight`: `500` — Medium
- `--code-font-weight`: `500` — Medium
- `--text-font-weight`: `500` — Medium
- `--header-font-weight`: `700` — Bold

### Full Font Size Scale

Sizes detected in the design (descending): `112px`, `72px`, `60px`, `48px`, `38px`, `32px`, `24px`, `20px`, `18px`, `16px`, `15px`, `13px`, `12px`, `11px`, `10px`

> 9 size(s) detected outside the sampled hierarchy (72px, 60px, 38px, 32px, 24px, 20px, 18px, 12px, 11px). 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:

- **contextual alternates** (`calt`) — connections between letters refined contextually

**Clone instruction:** Enable these in your CSS:
```css
body {
  font-feature-settings: "calt", "cv01", "cv11", "cv12", "cv13", "ss07", "pnum";
}
```

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Input**:
  - **focus:** text #b9b9b9 → #ffffff, border changes

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

```yaml
component-behaviors:
  button:
    default:
      bg: "rgb(255, 255, 255)"
      fg: "rgb(11, 11, 11)"
      border: "1px solid rgb(11, 11, 11)"
    focus:
      bg: "transparent"
      fg: "inherit"
  input:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(185, 185, 185)"
    focus:
      bg: "transparent"
      fg: "rgb(255, 255, 255)"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"

      fg: "rgb(185, 185, 185)"
  footerLink:
    default:
      bg: "color(display-p3 1 0.3333 0)"
      fg: "rgb(11, 11, 11)"

```

**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
- **2 shape(s)** in this system: `Pill`, `Dark / Solid`
- **DO NOT introduce new buttons variants** without justification

### Inputs & Forms
- **1 shape(s)** in this system: `Text Input`
- **DO NOT introduce new inputs & forms variants** without justification

### Navigation
- **1 shape(s)** in this system: `Main Nav`
- **DO NOT introduce new navigation variants** without justification

### Status Badges
- **1 shape(s)** in this system: `Neutral Dark`
- **DO NOT introduce new status badges variants** without justification

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

| Primary Input | `3px` |

**Shape Personality**: Sharp + Pill Contrast — Angular precision with pill-shaped accents (status badges, tags). Creates strong visual hierarchy.

**Full Radius Spectrum**: 3px, 4px, 5px, 6px, 8px, 11px, 12px, full/pill (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~96px internal vertical padding (up to 128px) — **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** | `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).

**5/8 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:** "Structure powers intelligence" — 112px left-aligned
- **Subheading:** "The back-end built for AI content operations. Power web, mobile, and agentic applications at scale."
- **Media:** present, positioned top
- **CTAs:** 3 (primary: "Start building")
- **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:** logo-left-links-right — Logo at far left, primary navigation links right-aligned
- **Height:** 35px
- **Logo:** ✓ present
- **Nav links:** 5 primary items
- **CTAs in nav:** 3
- **Clone instruction:** Build a static logo left links right navigation. Reserve 3 slots for primary CTAs.

### Card Grid Pattern

- **Card count:** 5 cards detected
- **Columns (desktop):** 3-up grid
- **Card dimensions:** 461×833px (aspect 0.55:1)
- **Gap:** 0px between cards
- **Content:** ✓ image + CTA
- **Image position:** none
- **Clone instruction:** Build a 3-column grid (desktop) with cards at ~0.55:1 aspect ratio. Each card has an image at the none.

### Testimonial Pattern

- **Count:** 3 testimonial blocks
- **Layout:** list
- **Avg quote length:** 170 chars (medium quote)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
- **Clone instruction:** Build a list of 3 testimonials.   

### CTA Banner Pattern

- **Banner count:** 5
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Publish"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgb(0, 82, 239) 0px 0px 0px 1px` | Cards, elevated surfaces |
| Inset (Level 2) | <br>`rgb(255, 255, 255) 0px 0px 0px 1px inset` | Buttons, pressed-state elements |

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

## 7. Motion & Interaction

### Easing System

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 25 unique animations (25 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 Black (`#0b0b0b`) for text — not pure black, it's warmer and more readable
- Use waldenburgNormal as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-4.48px) 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 #0052ef (`#0052ef`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Make the hero full-viewport (≥70% screen height) — this design uses an immersive hero, not a tall navbar
- Include exactly 3 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose
- Each card includes a none image — imagery is part of the card identity, not optional
- Use a 3-column grid on desktop — density matters for this content type
- Repeat the primary CTA across 5 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 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 use rectangular buttons for primary actions — the rounded pill shape is the brand standard
- 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(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(0, 82, 239)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(0, 82, 239)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 376px | Single column, compact spacing |
| Mobile | 479px | Single column, compact spacing |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1000px | Multi-column grids begin |
| Desktop | 1100px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `112px` | `60px` |
| heading | line-height | `112px` | `60px` |
| heading | letter-spacing | `-4.48px` | `-2.4px` |
| button | width | `241.859px` | `270px` |
| card | width | `400px` | `114px` |

### Collapsing Strategy
- Headlines: 112px → 60px 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: 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):

- **Navigation collapses to hamburger** — 5 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle).
- **Nav CTAs reduced** on mobile (3 → 2) — the design prioritizes content over conversion buttons at small sizes.
- **Card grid: 3-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.*

- **Clip-path shapes** — 8 non-rectangular cut(s).
- **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands.
- **CSS-variable animations** (3) — animated custom properties.

> **Motion fingerprint**: non-rectangular shapes (10), CSS scroll-driven animations

## 9b. Visual Tone & Photography

**Tone:** Photography-driven

The site is dominated by photography (JPG/WebP). Photos carry the brand voice as much as the typography. Use authentic, brand-appropriate imagery — generic stock will degrade quality.

**Canonical Brand Image (OG):**
- https://cdn.sanity.io/images/3do82whm/next/f21df064721ee7867372278bcbd0de4b512de556-1200x630.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: 1.23:1 (landscape)
- Rendered size: 1440×1168px
- *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): 11 (69%)
- Portrait (<0.87): 5 (31%)
- Square (0.87–1.15): 0 (0%)

**Media Format Mix:**
- JPG: 8 (typically photographic content)
- WebP: 3 (optimized photo/illustration hybrid)
- PNG: 5 (logos, transparent UI elements, mockups)
- SVG: 2 (icons, illustrations, decorative geometry)

**Average rendered image size:** 957×780px
**Above-fold image count:** 1 / 16

**Decorative Patterns Detected:**
- 2 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
- 5 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:**
- Source authentic photography (or licensed stock that matches the brand mood) — placeholders will visibly degrade the clone.
- Match the dominant aspect ratio (see above) so card grids and hero compositions hold.

## 10. Agent Prompt Guide

### Quick Reference
- Background: White (`#ffffff`)
- Primary text: Black (`#0b0b0b`)
- Accent: #0052ef (`#0052ef`)
- Border: Translucent Deep Navy (20%) (`rgba(18, 25, 35, 0.2)`)
- Font: waldenburgNormal
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on White background (#ffffff). Headline at 112px waldenburgNormal weight 400, line-height 1, letter-spacing -4.48px, color #0b0b0b."
- "Create the primary CTA button: `#0052ef` background, `#ffffff` text, 9999px border-radius, 4px 12px padding, 600 weight, waldenburgNormal font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: relative on `#ffffff`. waldenburgNormal 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to White (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in waldenburgNormal, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: #0052ef (`#0052ef`) is the sole interactive color. On hover → Translucent Cobalt Blue (80%) (`rgba(0, 65, 198, 0.8)`). 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, 200ms for layout changes. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `9999px`, 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.*

    - "Mirror how your content operations team works"
    - "Content Operations without the busywork"
    - "Everything your team needs in one place"
    - "Enterprise-grade everything"

**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: 38
    avg-ratio: 3.32
    common-aspect: "~16:6 banner"
    sample-alts:
      - "Mejuri"
      - "Redis"
      - "Replit"
  hero:
    count: 1
    avg-ratio: 1.82
    common-aspect: "~16:9 landscape"
```

**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">
  CUSTOMIZE YOUR CHOICES
</button>
```
_Source pattern detected: padding `8px` · radius `9999px` · 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** 4 · **cta** 3 · **auth** 1 · **pricing** 1 · **docs** 9 · **project** 1 · **social** 10 · **legal** 1 · **footer** 16 · **other** 14

**Primary actions (conversion path):**
- Account access — "LOG IN" (login/signup) → `https://www.sanity.io/entry?ref=navbar`
- Primary call-to-action — "GET STARTED" (the conversion path) → `https://www.sanity.io/get-started?ref=navbar`
- Primary call-to-action — "Start building" (the conversion path) → `https://www.sanity.io/get-started`
- Primary call-to-action — "Get Started Now Get Started Now" (the conversion path) → `https://www.sanity.io/get-started`

## 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 (ibmPlexMono, waldenburgNormal)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).

*✅ No critical extraction gaps detected — high-confidence reproduction expected.*

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 509 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 7 typography roles inferred |
| §4 Components | High | 5 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 21 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 16 images, hero present |

## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+)

*Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS). Copy-paste into your `<style>` block.*

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 3221 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**19 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
`376px` · `400px` · `479px` · `480px` · `600px` · `700px` · `719px` · `720px` · `767px` · `768px` · `800px` · `959px` · `960px` · `1000px` … (+5 more)

### Measured Design Scale
**Type scale by usage** (× = paint count): `12px`×1151 · `13px`×862 · `16px`×849 · `15px`×117 · `10px`×55 · `60px`×37 · `38px`×28 · `18px`×24

**Radius scale** (× = paint count): `12px`×19 · `9999px`×18 · `5px`×15 · `4px`×8 · `3px`×7 · `6px`×5 · `11px`×1 · `8px`×1

**Weights** (× = paint count): `400`×3170 · `500`×22 · `425`×15 · `700`×8 · `600`×4

**Layout gaps** (× = paint count): `normal 2px`×37 · `12px`×18 · `8px`×14 · `normal 6px`×11 · `normal 12px`×10 · `16px normal`×9 · `4px`×8 · `24.16px normal`×7

**Elevation (real shadows)**:
```css
rgb(0, 82, 239) 0px 0px 0px 1px
rgb(255, 255, 255) 0px 0px 0px 1px inset
```

### 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-sans,var(--font-sans)) }
header { background-color:var(--color-bg-base,var(--color-bg-base)) }
main { background-color:var(--color-bg-base,var(--color-bg-base)) }
