description: "Dark-canvas product system built on #0e1312 with #0e1312 as the single brand accent. Type anchored in TASA Orbiter at 248px / weight 400. Extracted automatically from https://motion.dev/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
narrative: |
  motion.dev is built on a near-black canvas (rgb(14, 19, 18)).
  The system uses rgb(14, 19, 18) as a near-neutral accent (low saturation).
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside TASA Orbiter as the primary typeface.
  TASA Orbiter is paired with Inter for secondary roles.
  A restrained elevation system (1 distinct shadow) — shadows reserved for the few elements that must lift off the page.
  Motion is a first-class concern — 8 keyframe animations plus transition-driven interactions.

# Design System — motion.dev
> Extracted automatically by Prism from https://motion.dev
> 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**: heavy  |  **Aesthetic**: dark-premium

| Dimension | Value | Signal |
|---|---|---|
| Canvas | dark | `#0e1312` |
| Type posture | sans-led (TASA Orbiter) | "Ticker" |
| Color assertion | dual-accent | #0e1312 |
| Whitespace | moderate | section rhythm 40px |
| Interaction | animated | 8 keyframes, 16 transitions |
| Radius language | 0px-architectural | from token scale |

**Prism fingerprint**: `dark-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(14, 19, 18)` is the page background. Every component composits against this.
> - **Accent**: `rgb(14, 19, 18)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 40px between major bands. Card padding: 24px.
> - **Default radius**: 10px 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

**Signature:** a radial gradient glow in the hero. This is the brand's most recognizable visual — reproduce it, don't replace it with a generic card or flat panel.

motion.dev commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a dark surface (`#0e1312`) 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 **TASA Orbiter**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. Negative letter-spacing at display sizes (-2.4px at 48px) compresses headlines into engineered blocks, dense and authoritative. 

Body text reads in Whitesmoke (`#ededec`). **Near-Black** (`#0e1312`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (1 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. The site uses a variable font with OPSZ + WGHT axes, enabling precise weight/width control across the type hierarchy. 

**Key Characteristics:**
- Background: Near-Black (`#0e1312`)
- Primary typeface: Geist Mono
- Primary text: Whitesmoke (`#ededec`)
- Accent: Near-Black (`#0e1312`)
- Display: 48px weight 700, letter-spacing -2.4px
- Border: Slate Grey (`#6e6a64`) — border-based containment
- Shadow system: 1 distinct elevation levels
- Custom fonts loaded: Geist Mono, Inter, TASA Orbiter, League Gothic

### Full Font Size Scale

Sizes detected in the design (descending): `52px`, `48px`, `24px`, `22px`, `20px`, `18px`, `16px`, `14px`, `13px`, `12px`, `11.50px`, `11.05px`, `11px`, `10.50px`, `10px`

> 8 size(s) detected outside the sampled hierarchy (48px, 22px, 20px, 18px, 14px, 11.5px, 11.05px, 10.5px). 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:

- **tabular figures** (`tnum`) — numbers align vertically, essential for pricing tables and dashboards
- **stylistic sets** (`ss0X`) — alternate letterforms enabled (often for brand-specific glyph variants)

**Clone instruction:** Enable these in your CSS:
```css
body {
  font-feature-settings: "ss03", "cv05", "tnum";
}
```

**Variable font axes:**
- OPSZ axis
- WGHT axis

## 5. Layout Principles

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

### Grid
Flexbox column

### Max Width
980px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 8px |
| md | 12px |
| base | 16px |
| lg | 24px |
| xl | 28px |
| 2xl | 40px |
| 3xl | 60px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 3px | Tiny corners (badges, micro elements) |
| Sm | 10px | Buttons, inputs, small elements |
| Md | 999px | Cards, containers |
| Lg | 1007px | Large rounded elements, pill segments |
| Xl | 1015px | Category strips, featured containers |
| Full | 999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `0px` |
| Cards & Containers | `0px` |
| Inputs & Forms | `0px` |
| Navigation | `none` |
| CTA Banners | `0px` |
| Status Badges | `0px` |
| Code Blocks | `3px` |
| Page Body | `0px` |
| Primary Input | `0px` |

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

**Full Radius Spectrum**: 0px, 3px, 10px, 999px (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~60px internal vertical padding (up to 80px) — **standard**. (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** | `60px` | Top/bottom of full-bleed hero sections |
| **section** | `28px` | 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:** left-aligned — 
- **Viewport coverage:** 144px tall (not full-viewport)
- **Heading:** "Motion.Production-grade animation for the web." — 48px left-aligned
- **CTAs:** none detected in hero (unusual — agent should verify)
- **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text.

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** unknown — Layout not classified
- **Height:** 27px
- **Logo:** ✗ absent
- **Nav links:** 4 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 8 cards detected
- **Columns (desktop):** 6-up grid
- **Card dimensions:** 236×346px (aspect 0.68:1)
- **Gap:** 12px between cards
- **Content:** ✗ no image + icon
- **Clone instruction:** Build a 6-column grid (desktop) with cards at ~0.68:1 aspect ratio. Text/icon-only cards (no photography).

### Pricing Table Pattern

- **Tier count:** 2 pricing tiers
- **Layout:** vertical stacked
- **Columns (desktop):** 2-up
- **Clone instruction:** Build a 2-column vertical-stack pricing comparison.

### Footer Pattern

- **Columns:** 2
- **Links:** 3 total
- **Height:** 36px
- **Includes:** ✗ no newsletter | ✗ no social |  
- **Clone instruction:** Build a 2-column footer with ~2 links per column.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |
| Layered (Level 1) | <br>`rgba(0, 0, 0, 0.5) 0px 24px 48px -18px`,<br>`rgba(0, 0, 0, 0.28) 0px 10px 20px -8px` | Cards, elevated surfaces |

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

## 7. Motion & Interaction

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `120ms` | Fast | Hover states, micro-interactions |
| `150ms` | Fast | Hover states, micro-interactions |

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `180ms`)
- **Dominant Easing**: standard CSS easings
- **Animation Library**: 8 unique animations (8 total including variants)

> This design moves with balanced pacing timing using standard CSS easings, creating a UI that feels natural and fluid.

## 8. Do's and Don'ts

### Do
- Use dark background (`#0e1312`) as the foundation — this is a dark-mode-native design
- Use TASA Orbiter as the primary typeface — it defines the brand personality
- Use negative letter-spacing (-2.4px) 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 Near-Black (`#0e1312`) as the primary accent — it's the brand's signature interactive color
- Each card uses an icon (not photo) — the visual language is illustrative, not photographic
- Use a 6-column grid on desktop — density matters for this content type

### 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 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
- Don't over-build the footer — this design keeps it minimal (2 cols, 3 links)


## 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(14, 19, 18)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(14, 19, 18)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(14, 19, 18)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(14, 19, 18)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 400px | Single column, compact spacing |
| Mobile | 480px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 760px | Expanded mobile layout |
| Tablet | 1000px | Multi-column grids begin |
| Desktop | 1100px | Full feature layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `48px` | `33.15px` |
| heading | line-height | `48px` | `33.15px` |
| heading | letter-spacing | `-2.4px` | `-1.6575px` |
| nav | height | `27px` | `22px` |
| hero | height | `127.75px` | `528.219px` |
| card | width | `236px` | `350px` |
| main | padding | `0px 24px` | `0px 20px` |

### Collapsing Strategy
- Headlines: 48px → 33.15px on mobile
- Container padding: 0px 24px → 0px 20px 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 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):

- **Card grid: 6-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.
- **Mesh gradients** — 1 multi-stop organic color field(s) as background atmosphere.
- **Clip-path shapes** — 3 non-rectangular cut(s).

> **Motion fingerprint**: Canvas 2D, mesh gradients, non-rectangular shapes (3)

## 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://api.motion.dev/site/og/page/home.png?title=Motion&description=The+production-grade+animation+library+for+React%2C+JavaScript+and+Vue. (1200×630px)
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Aspect Ratio Distribution:**
- Landscape (1.15–2.3): 6 (100%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)

**Media Format Mix:**
- PNG: 6 (logos, transparent UI elements, mockups)

**Average rendered image size:** 148×93px
**Above-fold image count:** 0 / 6

**Decorative Patterns Detected:**
- 2 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 2 radial gradients — circular color blooms used for spotlight/glow effects
- **Glassmorphism** detected (`backdrop-filter: blur`) — layered transparent surfaces with blur, modern OS-like aesthetic

**Clone instruction for decorative work:** This is a gradient-rich design — invest in multi-stop CSS gradients (3+ color stops), not solid backgrounds.

**Imagery Guidance for clones:**
- Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents.
- Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Near-Black (`#0e1312`)
- Primary text: Whitesmoke (`#ededec`)
- Accent: Near-Black (`#0e1312`)
- Border: Slate Grey (`#6e6a64`)
- Font: TASA Orbiter
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Near-Black background (#0e1312). Headline at 48px TASA Orbiter weight 700, line-height 1, letter-spacing -2.4px, color #ededec."
- "Create the primary CTA button: `#0e1312` background, `#0e1312` text, 999px border-radius, 8px 10px padding, 700 weight, TASA Orbiter font."
- "Design a card on `#141a18` background. Border: 1px solid rgb(30, 38, 35). Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#0e1312`. TASA Orbiter 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Near-Black (`#0e1312`) — every component is composited against this exact base.
2. **Typography**: All type in TASA Orbiter, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Near-Black (`#0e1312`) is the sole interactive color. On hover → Accent (`#ffdb2a`). Use CSS transitions, not opacity/brightness filters.
4. **Shape**: CTAs at `0px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
5. **Spacing**: Use the `--ca-space-*` token scale (4px–28px). 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:
    - "Animations that move."
    - "Made with Motion."
    - "Trusted by the world's leading teams."
    - "The professional animation toolkit. Yours forever."
  sub-headings:
    - "Partners"
    - "Platinum"
    - "SPONSORS"
  ctas:
    - "MOTION+"
    - "GET STARTED"
    - "GET MOTION+"
    - "RUN FREE AUDIT"
    - "BECOME A SPONSOR"
    - "SUBSCRIBE"
  navigation:
    - "Motion"
    - "REACT"
    - "JAVASCRIPT"
    - "VUE"
    - "BROWSE ALL EXAMPLES"
    - "BECOME A SPONSOR"
    - "SEE FULL PRICING"
    - "LEARN MORE"
    - "BROWSE ALL DOCS"
    - "DOCS"
  footer-links:
    - "BECOME A SPONSOR"
    - "About"
```

**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: 6
    avg-ratio: 1.59
    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">
  Action
</button>
```
_Source pattern detected: padding `8px 10px` · radius `0px` · weight `400`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `0px` · radius `0px` · shadow `none`_

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


## 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** 1 · **docs** 26 · **social** 2 · **footer** 1 · **other** 26

**Primary actions (conversion path):**
- Primary call-to-action — "GET STARTED" (the conversion path) → `https://motion.dev/docs`

**Projects / case studies detected** (clustered by URL + featured image):

*Docs* — medium confidence, 12 items:

| Title | Featured image | Link |
|---|---|---|
| REACT | — | https://motion.dev/docs/react |
| JAVASCRIPT | — | https://motion.dev/docs/quick-start |
| VUE | — | https://motion.dev/docs/vue |
| React | — | https://motion.dev/docs/react-animation |
| React | — | https://motion.dev/docs/animate |
| React | — | https://motion.dev/docs/vue-animation |
| React | — | https://motion.dev/docs/react-scroll-animations |
| React | — | https://motion.dev/docs/scroll |

*Examples* — medium confidence, 6 items:

| Title | Featured image | Link |
|---|---|---|
| Scroll velocity: 3D planes | `scroll-velocity-linked-offset.png` (ar 1.33) | https://motion.dev/examples/react-scroll-velocity-linked-offset |
| Typewriter | `typewriter.png` (ar 1.33) | https://motion.dev/examples/react-typewriter |
| iOS App Folder | `ios-app-folder.png` (ar 1.33) | https://motion.dev/examples/react-ios-app-folder |
| iOS pointer animation | `ios-pointer.png` (ar 1.33) | https://motion.dev/examples/react-ios-pointer |
| Pokopia: Modal | `pokopia-modal.png` (ar 1.33) | https://motion.dev/examples/react-pokopia-modal |
| Floating Action Button | `floating-action-button.png` (ar 1.33) | https://motion.dev/examples/react-floating-action-button |

**Signals:** 44/60 links carry a featured image · dominant link roles: content-card (37), inline-link (10), footer-link (6).

## Extraction Completeness: 84/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|

## 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 (Inter, TASA Orbiter, League Gothic)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).

| Category | What's missing | Fallback strategy |
|----------|----------------|-------------------|
| **Hero imagery** | No dominant hero image detected above the fold | Use the canonical brand visual from §9b (OG image) for hero composition |
| **Dark mode** | Dark surface is the canonical medium; no separate light-mode variables detected | The dark canvas IS the design — reproduce it as the default. Do not generate a light-mode variant unless explicitly requested |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | Medium | 27 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 7 typography roles inferred |
| §4 Components | High | 7 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 | Medium | 6 images, hero not detected |

### Brand Gradient Palette

**15 complex gradients captured** from the site's CSS. The first few are the most prominent visual decorations:

```css
/* Gradient 1 */
background: linear-gradient(to right,color-mix(in srgb,#fff 8%,transparent);

/* Gradient 2 */
background: linear-gradient(to bottom,color-mix(in srgb,#fff 8%,transparent);

/* Gradient 3 */
background: linear-gradient(to right,color-mix(in srgb,var(--foreground);

/* Gradient 4 */
background: linear-gradient(to bottom,color-mix(in srgb,var(--foreground);

/* Gradient 5 */
background: linear-gradient(to right,#fbbf24 0,#fbbf24 calc(100% / 6 - 4px);

```

### Hover State CSS (Intercepted)

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 2038 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**18 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
`400px` · `480px` · `540px` · `600px` · `640px` · `700px` · `720px` · `760px` · `768px` · `780px` · `800px` · `880px` · `900px` · `960px` … (+4 more)

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×969 · `10px`×407 · `11px`×277 · `12px`×127 · `13px`×126 · `11.05px`×28 · `11.5px`×20 · `14px`×18

**Radius scale** (× = paint count): `3px`×28 · `999px`×8 · `10px`×5 · `50%`×4 · `8px`×3 · `16px`×1

**Weights** (× = paint count): `400`×1950 · `420`×44 · `700`×26 · `600`×10 · `480`×4 · `500`×2

**Layout gaps** (× = paint count): `8px`×64 · `6px`×49 · `12px`×37 · `10px`×31 · `14px`×26 · `16px`×12 · `18px`×10 · `28px`×6

**Elevation (real shadows)**:
```css
rgba(0, 0, 0, 0.5) 0px 24px 48px -18px, rgba(0, 0, 0, 0.28) 0px 10px 20px -8px
rgba(0, 0, 0, 0.2) 0px 8px 32px 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 { background-color:var(--background); color:var(--foreground) }
header { gap:24px; background:color-mix(in srgb,var(--background) 80%,transparent) }
header { transition:background-color .24s ease,color .24s ease }
header { background:var(--accent) }
nav { gap:4px }
h1 { font-size:38px }
h1 { font-family:var(--font-sans); font-size:clamp(24px,5.4vw,48px); color:var(--background) }
h2 { font-size:32px }
h2 { font-family:var(--font-sans); font-size:clamp(34px,4.4vw,52px); color:var(--foreground) }
button { gap:6px; background:transparent; color:var(--foreground); font-family:var(--font-mono); font-size:11px; transition:opacity .15s; background-color:transparent }
button { color:var(--background) }
a { color:var(--accent) }
```

> 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.
