description: "Dark-canvas product system built on #ffffff. Type anchored in D-DIN-Bold at 60px / weight 400. Extracted automatically from https://spacex.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
narrative: |
  spacex.com is built on a near-black canvas (rgb(0, 0, 0)).
  Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside D-DIN-Bold as the primary typeface.
  D-DIN-Bold is paired with Roboto Mono for secondary roles.
  Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model.
  Motion is a first-class concern — 7 keyframe animations plus transition-driven interactions.

# Design System — spacex.com
> Extracted automatically by Prism from https://spacex.com
> 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**: subtle  |  **Weight**: heavy  |  **Aesthetic**: engineering-minimal

| Dimension | Value | Signal |
|---|---|---|
| Canvas | dark | `#000000` |
| Type posture | sans-led (D-DIN) | "Starship's Twelfth Flight Test" |
| Color assertion | single-accent | N/A |
| Whitespace | moderate | section rhythm 40px |
| Interaction | subtle | 7 keyframes, 8 transitions |
| Radius language | 4px-rounded | from token scale |

**Prism fingerprint**: `dark-canvas · sans-display · single-accent · 4px-rounded · subtle-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(0, 0, 0)` is the page background. Every component composits against this.
> - **Accent**: `N/A` 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**: 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

spacex.com commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a near-pure-black surface (`#000000`) where surfaces are layered through stepped luminance — each elevated level is slightly less dark than the one beneath it, creating depth without color shifts. 

Headlines are set in **D-DIN-Bold**, a sans-serif display face (the dominant type signature, e.g. "Starship's Twelfth Flight Test" at 60px). Body text is set in **D-DIN**. 

Body text reads in Off-White (`#f0f0fa`) (contrast ratio 19.9:1, well above WCAG AA). 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: Pure Black (`#000000`)
- Primary typeface: D-DIN
- Primary text: Off-White (`#f0f0fa`)
- Accent: Slate Grey (`#808080`)
- Custom fonts loaded: D-DIN, D-DIN-Bold, Roboto Mono

## 2. Color Palette & Roles

### Background & Surface
- **Pure Black** (`#000000`): Page background (primary)
- **#0000ee** (`#0000ee`): Surface / elevated background

### Text & Content
- **Off-White** (`#f0f0fa`): Primary body text
- **Slate Grey** (`#808080`): Secondary text

### Full Extracted Palette
**6 colors rendered on the page** + **1** more declared in design tokens (CSS custom properties — not necessarily painted). (4 categorized above + 3 additional below.)
Rendered values are read via `getComputedStyle()`; token values come from CSS variable declarations. Third-party logo colors are filtered out.

- `rgba(255, 255, 255, 0.25)` — Translucent Pure White (25%)
- `#d9d9d9` — Light Grey
- `rgba(37, 38, 40, 0.8)` — Translucent Warm Brown (80%) *(token)*

## 3. Typography Rules

### Font Families
- **Primary**: `D-DIN`
- **Secondary**: `D-DIN-Bold`
- **Font 3**: `Roboto Mono`

### Custom Fonts Loaded
- **D-DIN** weight 400 (normal)
- **D-DIN-Bold** weight 400 (normal)
- **Roboto Mono** weight 400 (normal)

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | D-DIN-Bold | 80px | 400 | 0.95 | 1.6px | Main headline (h2) |
| Section Heading | D-DIN-Bold | 60px | 400 | 0.9 | -1px | Section titles (h2) |
| Card Title | D-DIN | 16px | 400 | 1.7 | normal | Card headings |
| Button | D-DIN | 13.3333px | 400 | normal | normal | Button label (13.3333px) |
| Link | D-DIN | 13.008px | 700 | 0.94 | 1.17072px | Link (13.008px) — Decoration: none |

### Full Font Size Scale

Sizes detected in the design (descending): `80px`, `60px`, `48px`, `16px`, `13.33px`, `13.01px`, `12px`, `10px`

> 3 size(s) detected outside the sampled hierarchy (48px, 12px, 10px). These appear on elements not in the sampled set — likely additional display sizes, marketing-section overrides, or third-party-widget styles.

## 4. Component Stylings

### Buttons

**Subtle**
- Background: `rgba(0, 0, 0, 0.5)`
- Text: `#f0f0fa` `{colors.ink}`
- Padding: 0px 20px
- Radius: 4px
- Border: 1px solid rgba(240, 240, 250, 0.35)
- Font: 16px weight 400
- Use: Quiet action against page bg
- Focus: backgroundColor: `rgba(12, 12, 12, 0.514)`, outline: `rgb(16, 16, 16) auto 1px`

### Cards & Containers

**Standard Card**
- Background: `transparent`
- Padding: 20px 10px 20px 6px
- Radius: 0px
- Use: Content containers, listing items


## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Button**:
  - **focus:** bg rgba(0, 0, 0, 0.5) → rgba(12, 12, 12, 0.514)

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

```yaml
component-behaviors:
  button:
    default:
      bg: "rgba(0, 0, 0, 0.5)"
      fg: "rgb(240, 240, 250)"
      border: "1px solid rgba(240, 240, 250, 0.35)"
    focus:
      bg: "rgba(12, 12, 12, 0.514)"
      fg: "inherit"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 238)"
  card:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(240, 240, 250)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 238)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(0, 0, 238)"
```

**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
- **1 shape(s)** in this system: `Subtle`
- **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

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
1200px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 3px |
| sm | 6px |
| md | 10px |
| base | 16px |
| lg | 24px |
| xl | 30px |
| 2xl | 40px |
| 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 | 32px | Cards, containers |
| Lg | 40px | Large rounded elements, pill segments |
| Xl | 48px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `4px` |
| Cards & Containers | `0px` |
| Page Body | `0px` |
| Navigation | `0px` |

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

**Full Radius Spectrum**: 4px, 8px, 32px (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** | `30px` | Between major bands (color change, content shift) |
| **subsection** | `24px` | Within a section, between content groups |
| **card** | `10px` | Card padding, list-item spacing |
| **compact** | `6px` | Form fields, tight clusters, badge padding |
| **micro** | `3px` | 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:** left-aligned — 
- **Viewport coverage:** 295px tall (not full-viewport)
- **Heading:** "Making life multiplanetary" — 80px left-aligned
- **Subheading:** "SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not."
- **CTAs:** 1 (primary: "EXPLORE")
- **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:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 74px
- **Logo:** ✓ present
- **Nav links:** 21 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static logo left links left navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 5 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1440×941px (aspect 1.53:1)
- **Gap:** 0px between cards
- **Content:** ✓ image + CTA
- **Image position:** top
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.53:1 aspect ratio. Each card has an image at the top.

### Footer Pattern

- **Columns:** 1
- **Links:** 5 total
- **Height:** 75px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~5 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

### Dominant Easing Curves

| Curve | Semantic Name |
|-------|---------------|
| `cubic-bezier(0.19,1,0.22,1)` | Expo Out — Snappy Deceleration |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `200ms` | Normal | Panel open/close, navigation |
| `300ms` | Normal | Panel open/close, navigation |
| `500ms` | Slow | Hero animations, page transitions |
| `1s` | Cinematic | Splash, marketing reveals |

### Copy-Paste Transition Snippets

**Opacity**
```css
transition: opacity 0.3s;
```

**All Props**
```css
transition: max-height 0.5s, padding-top 0.5s;
```

**All Props**
```css
transition: left 1s, opacity 1s, visibility 1s;
```

**Background**
```css
transition: background-color 0.5s cubic-bezier(0.19, 1, 0.22, 1);
```

### Keyframe Animation Catalog

| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `hide` | Fade | opacity | UI transition |
| `reveal-header` | Fade + Move | opacity, transform | UI transition |
| `reveal-subheader` | Fade + Move | opacity, transform | UI transition |
| `reveal-button` | Fade + Move | opacity, transform | UI transition |
| `spin` | Rotate / Spin | transform | Loading indicator |
| `slide-in` | Fade | left, opacity | Panel / drawer enter |
| `slide-out` | Fade | left, opacity | Panel / drawer exit |

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `500ms`)
- **Dominant Easing**: exponential ease-out (snappy)
- **Animation Library**: 7 unique animations (7 total including variants)

> This design moves with deliberate & calm timing using exponential ease-out (snappy), creating a UI that feels calm and controlled.

## 8. Do's and Don'ts

### Do
- Use dark background (`#000000`) as the foundation — this is a dark-mode-native design
- Use D-DIN as the primary typeface — it defines the brand personality
- The system uses a single text weight (400) — hierarchy comes from size and color, not weight
- Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
- Apply 20px 10px 20px 6px padding inside cards — matches the design system's content breathing room
- Respect the 3px–30px spacing range — the design uses a wide scale for visual breathing room
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Each card includes a top image — imagery is part of the card identity, not optional

### 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 introduce bolder or lighter weights — 400 is the only weight in this system
- 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
- 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 (1 cols, 5 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(0, 0, 0)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(0, 0, 0)'"
  - 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 Large | 600px | Expanded mobile layout |
| Tablet | 960px | Multi-column grids begin |
| Desktop | 1279px | Full feature layout |
| Large Desktop | 1350px | Maximum content width |
| Large Desktop | 1500px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| body | font-size | `16px` | `10px` |
| body | line-height | `24px` | `12px` |
| nav | flex-direction | `row` | `column` |
| nav | padding | `24px 40px` | `24px 0px` |
| nav | height | `26px` | `62px` |
| button | font-size | `16px` | `10px` |
| button | width | `auto` | `24px` |
| card | padding | `20px 10px 20px 6px` | `8px 0px 40px` |
| card | width | `243.656px` | `362px` |

### Collapsing Strategy
- 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: 0px 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** — 21 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle).


## 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.*

- **Glassmorphism** — 1 frosted/blur layer(s) (e.g. `blur(6px)`).

> **Motion fingerprint**: glassmorphism (1 layers)

## 9b. Visual Tone & Photography

**Tone:** Mixed photography + illustration

A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents.

**Canonical Brand Image (OG):**
- https://www.spacex.com/assets/images/share.jpg
  *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: 1:1 (square / portrait)
- Rendered size: 64×64px
- *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 (50%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 2 (50%)

**Media Format Mix:**
- JPG: 4 (typically photographic content)

**Average rendered image size:** 752×503px
**Above-fold image count:** 2 / 4

**Decorative Patterns Detected:**
- 12 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- **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: Pure Black (`#000000`)
- Primary text: Off-White (`#f0f0fa`)
- Accent: Ring Blue (`#3b82f6`)
- Border: Translucent Pure White (25%) (`rgba(255, 255, 255, 0.25)`)
- Font: D-DIN
- Body: 16px weight 400

### Example Component Prompts
- "Create the primary CTA button: `transparent` background, `#f0f0fa` text, 9999px border-radius, 12px 24px padding, 700 weight, D-DIN font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 20px 10px 20px 6px."
- "Build navigation: static on `#000000`. D-DIN 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Pure Black (`#000000`) — every component is composited against this exact base.
2. **Typography**: All type in D-DIN, weight range 400–400. Never exceed 400 — heavier weights break the brand's tonal restraint.
3. **Motion**: All transitions use `cubic-bezier(0.19,1,0.22,1)`. Never use linear for UI transitions — preserve the brand's easing personality.
4. **Shape**: CTAs at `4px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
5. **Spacing**: Use the `--ca-space-*` token scale (3px–30px). 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.

## 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:
    - "STARSHIP'S TWELFTH FLIGHT TEST"
    - "MAKING LIFE MULTIPLANETARY"
    - "REVOLUTIONIZING SPACE TECHNOLOGY"
    - "WORLD’S LEADING LAUNCH SERVICE PROVIDER"
  ctas:
    - "WATCH"
  navigation:
    - "STARSHIP"
    - "DRAGON"
    - "FALCON 9"
    - "FALCON HEAVY"
    - "OVERVIEW"
    - "SPACE STATION"
    - "EARTH ORBIT"
    - "THE MOON"
    - "MARS & BEYOND"
    - "STARLINK"
  footer-links:
    - "CAREERS"
```

**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:
  thumbnail:
    count: 2
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
```

**Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`.


## 16. Component HTML Templates

*Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.*

### Button (primary action)
```html
<button class="btn btn-primary">
  WATCH
</button>
```
_Source pattern detected: padding `0px 20px` · radius `4px` · weight `400`_

### Generic Card
```html
<div class="card">
  <!-- content -->
</div>
```
_Source pattern detected: padding `20px 10px 20px 6px` · 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 · **social** 25 · **footer** 1 · **download** 1

**Signals:** 8/31 links carry a featured image · dominant link roles: social-link (17), content-card (6), footer-link (4).

## Extraction Completeness: 44/100 (D)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 6 | 25 | 4 named colors |
| Typography | 13 | 20 | 5 roles defined |
| Components | 8 | 20 | 2 specs extracted |
| Motion & Interaction | 12 | 15 | Keyframes |
| CSS Custom Properties | 1 | 10 | 16 vars |
| Responsive Breakpoints | 5 | 5 | 5 breakpoints |
| Variable Fonts | 0 | 5 | None detected |

## 12. Known Gaps & Confidence

Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback.

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

- **Licensed web fonts (D-DIN, D-DIN-Bold, Roboto Mono)** — 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 |
|----------|----------------|-------------------|
| **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 |
| **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside |
| **Design tokens** | Only 16 CSS custom properties (low signal for semantic naming) | Color names are nearest-neighbor approximations; verify against brand guidelines if available |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | Medium | 16 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 5 typography roles inferred |
| §4 Components | Low | 2 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 15 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 5 breakpoints detected |
| §9b Photography | High | 4 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.*

### Font Loading

3 font file(s) captured (127KB total). When running `prism add`, fonts are saved to `extractions/spacex.com/fonts/` and embedded as base64 in the output HTML.

**@font-face declarations to use:**
```css
@font-face {
  font-family: 'D-DIN';
  /* src: url('/fonts/D-DIN.woff2') format('woff2'); */
  font-weight: 400;
  font-style: normal;
  font-display: block;
}
@font-face {
  font-family: 'D-DIN-Bold';
  /* src: url('/fonts/D-DIN-Bold.woff2') format('woff2'); */
  font-weight: 400;
  font-style: normal;
  font-display: block;
}
@font-face {
  font-family: 'Roboto Mono';
  /* src: url('/fonts/Roboto-Mono.woff2') format('truetype'); */
  font-weight: 400;
  font-style: normal;
  font-display: block;
}
```

### Keyframe Animations (Intercepted from CSS)

**4 @keyframes found** — these are the real animation definitions:

```
@keyframes hide { ... }
@keyframes reveal-header { ... }
@keyframes reveal-subheader { ... }
@keyframes reveal-button { ... }
```

<details><summary>Full keyframes CSS (4 animations)</summary>

```css
@keyframes hide{0%{opacity:1}50%{opacity:1}60%{opacity:0}
@keyframes reveal-header{0%{opacity:0;transform:translateY(220%)}
@keyframes reveal-subheader{0%{opacity:0;transform:translateY(80%)}
@keyframes reveal-button{0%{opacity:0;transform:translateY(300%)}
```
</details>

### Hover State CSS (Intercepted)

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

```css
.innerhtml-from-cms a:hover{color:#ccc}

.metric-tile-second-description-innerhtml a:hover{color:var(--white-100)}
```

> **Note**: All values above are extracted from the live site's CSS files. The font files are saved locally by Prism and embedded in the output HTML. Use them as-is for maximum fidelity.

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 525 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**6 breakpoints** read from the live `@media` rules (not guessed):
`600px` · `960px` · `961px` · `1279px` · `1350px` · `1500px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `12px`×257 · `16px`×192 · `13.008px`×57 · `48px`×8 · `13.3333px`×4 · `10px`×2 · `60px`×2 · `80px`×2

**Radius scale** (× = paint count): `4px`×7 · `8px`×2 · `32px`×1

**Weights** (× = paint count): `400`×467 · `700`×57

**Layout gaps** (× = paint count): `normal 4px`×8 · `12px normal`×5 · `8px`×5 · `normal 30px`×1 · `normal 18px`×1 · `16px`×1 · `normal 36px`×1

### 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-weight:400; font-size:1rem; font-family:D-DIN, Arial, Verdana, sans-serif }
body { background-color:#000; color:var(--white-100) }
h2 { font-family:D-DIN-Bold; color:var(--white-100) }
h2 { font-weight:400 }
h2 { font-size:60px }
button { font-family:D-DIN }
button { background-color:var(--white-10); border-radius:2rem }
card { transition:left 1s,opacity 1s,visibility 1s; gap:1rem }
```

> 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.
