narrative: |
  fly.io is built on a pure-white canvas (rgb(255,255,255)).
  The system uses rgb(124, 58, 237) as the high-saturation accent for primary actions.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Mackinac as the primary typeface.
  A layered elevation system (11 distinct shadows) building a clear front-to-back hierarchy.
  Motion is a first-class concern — 17 keyframe animations plus transition-driven interactions.

# Design System — fly.io
> Extracted automatically by Prism from https://fly.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**: sparse  |  **Motion**: expressive  |  **Weight**: medium  |  **Aesthetic**: soft-rounded

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (Fricolage Grotesque) | "Build fast. Run any code" |
| Color assertion | dual-accent | #7c3aed |
| Whitespace | sparse | section rhythm 70px |
| Interaction | expressive | 17 keyframes, 12 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(124, 58, 237)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 70px between major bands. Card padding: 48px.
> - **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 gradient wash in the hero. This is the brand's most recognizable visual — reproduce it, don't replace it with a generic card or flat panel.

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

Headlines are set in **Mackinac**, a sans-serif display face (the dominant type signature, e.g. "Build fast. Run any code" at 64px). Body text is set in **Fricolage Grotesque**. Negative letter-spacing at display sizes (-2.88px at 64px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Translucent #281950 (75%) (`rgba(40, 25, 80, 0.75)`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Violet** (`#7c3aed`) 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 is built from multi-layer shadow stacks (11 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. 
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. The site uses a variable font with OPSZ axes, enabling precise weight/width control across the type hierarchy. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)

```

**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: `Pill`, `Ghost`, `Primary Brand`, `Outline`
- **DO NOT introduce new buttons variants** without justification

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

## 5. Layout Principles

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

### Grid
Single column, centered content

### Max Width
1200px

### Spacing System
Generous spacing — editorial breathing room

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 6px |
| sm | 20px |
| md | 32px |
| base | 40px |
| lg | 48px |
| xl | 56px |
| 2xl | 70px |
| 3xl | 72px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 8px | Tiny corners (badges, micro elements) |
| Sm | 10px | Buttons, inputs, small elements |
| Md | 16px | Cards, containers |
| Lg | 9999px | Large rounded elements, pill segments |
| Xl | 10007px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `9999px` |
| Navigation | `none` |
| Page Body | `0px` |

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

**Full Radius Spectrum**: 4px, 8px, 10px, 16px, 20px, full/pill (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~128px internal vertical padding (up to 198px) — **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** | `72px` | Top/bottom of full-bleed hero sections |
| **section** | `56px` | Between major bands (color change, content shift) |
| **subsection** | `48px` | Within a section, between content groups |
| **card** | `32px` | Card padding, list-item spacing |
| **compact** | `20px` | Form fields, tight clusters, badge padding |
| **micro** | `6px` | 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:** "Build fast. Run any code fearlessly." — 64px center-aligned
- **Subheading:** "The platform for devs who just want to ship. Powered by sandboxes that let you deploy any code with confidence."
- **Media:** present, positioned top
- **CTAs:** 1 (primary: "Deploy your app")
- **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:** 36px
- **Logo:** ✓ present
- **Nav links:** 0 primary items
- **CTAs in nav:** 0 (no buttons — links only)
- **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.

### Card Grid Pattern

- **Card count:** 4 cards detected
- **Columns (desktop):** 3-up grid
- **Card dimensions:** 536×122px (aspect 4.41:1)
- **Gap:** 64px between cards
- **Content:** ✗ no image + icon
- **Clone instruction:** Build a 3-column grid (desktop) with cards at ~4.41:1 aspect ratio. Text/icon-only cards (no photography).

### CTA Banner Pattern

- **Banner count:** 5
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background✓ gradient fill
- **Primary CTA text:** "Check Em Out!"
- **Clone instruction:** Place multiple CTA banners across page sections. Use gradient background.

### Footer Pattern

- **Columns:** 2
- **Links:** 23 total
- **Height:** 408px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 2-column footer with ~12 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 |
| Layered (Level 1) | <br>`rgba(32, 34, 55, 0.075) 0px 0px 0px 1px`,<br>`rgba(32, 34, 55, 0.05) 0px 10px 15px -3px`,<br>`rgba(32, 34, 55, 0.05) 0px 4px 6px -4px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.1) 0px 1px 3px 0px`,<br>`rgba(0, 0, 0, 0.1) 0px 1px 2px -1px` | Cards, elevated surfaces |
| Inset (Level 3) | <br>`rgba(67, 56, 202, 0.25) 0px 0px 0px 1px inset` | Buttons, pressed-state elements |
| Layered (Level 4) | <br>`rgba(86, 75, 128, 0.1) 1px 0px 0px 0px` | 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

### Dominant Easing Curves

| Curve | Semantic Name |
|-------|---------------|
| `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced |
| `cubic-bezier(0,0,0.2,1)` | Material Decelerate — Entrance |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `150ms` | Fast | Hover states, micro-interactions |
| `200ms` | Normal | Panel open/close, navigation |
| `300ms` | Normal | Panel open/close, navigation |
| `400ms` | Slow | Hero animations, page transitions |
| `500ms` | Slow | Hero animations, page transitions |

### Copy-Paste Transition Snippets

> 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 Translucent #281950 (75%) (`rgba(40, 25, 80, 0.75)`) for text — not pure black, it's warmer and more readable
- Use Fricolage Grotesque as the primary typeface — it defines the brand personality
- Keep font weights between 325-500 — the system uses a narrow weight range for subtle hierarchy
- Use negative letter-spacing (-2.88px) 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 Violet (`#7c3aed`) as the primary accent — it's the brand's signature interactive color
- Use 8px 20px 20px 8px border-radius on buttons — the standard corner rounding for interactive elements
- Respect the 6px–56px 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
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Each card uses an icon (not photo) — the visual language is illustrative, not photographic
- 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 use weight 700 (bold) or above — 500 is the maximum weight in this system
- 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


## 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(124, 58, 237)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(124, 58, 237)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 480px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1200px | Full feature layout |
| Large Desktop | 1367px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `64px` | `32px` |
| heading | line-height | `73.6px` | `38.4px` |
| heading | letter-spacing | `-2.88px` | `-1.44px` |

### Collapsing Strategy
- Headlines: 64px → 32px 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: 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):

- **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.
- **Footer columns collapse:** 2 columns (desktop) → 1 column (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.*

- **Glassmorphism** — 3 frosted/blur layer(s) (e.g. `blur(24px)`).

> **Motion fingerprint**: glassmorphism (3 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://fly.io/phx/images/preview/og-7ea9380853220ced249aaf88c2332937.jpg?vsn=d (1200×630px)
  *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: 1.78:1 (landscape (16:9-ish))
- Rendered size: 1400×787px
- *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): 5 (71%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 2 (29%)

**Media Format Mix:**
- WebP: 7 (optimized photo/illustration hybrid)
- SVG: 1 (icons, illustrations, decorative geometry)

**Average rendered image size:** 529×394px
**Above-fold image count:** 1 / 7

**Decorative Patterns Detected:**
- 47 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 1 large decorative SVG shape (≥200×200px, non-icon) — likely blob/illustration accents
- 1 background pattern (non-photo url() backgrounds) — textures/illustrations as backdrops
- **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 White (`#ffffff`)
- Primary text: Translucent #281950 (75%) (`rgba(40, 25, 80, 0.75)`)
- Accent: Violet (`#7c3aed`)
- Border: Transparent (`transparent`)
- Font: Fricolage Grotesque
- Body: 16px weight 325

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 64px Fricolage Grotesque weight 500, line-height 1.15, letter-spacing -2.88px, color rgba(40, 25, 80, 0.75)."
- "Create the primary CTA button: `#7c3aed` background, `#ffffff` text, 8px 20px 20px 8px border-radius, 0px 12px 0px 10px padding, 450 weight, Fricolage Grotesque font."
- "Build navigation: relative on `#ffffff`. Fricolage Grotesque 14.5px weight 450 for links."

### Iteration Guide
1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base.
2. **Typography**: All type in Fricolage Grotesque, weight range 325–500. Never exceed 500 — heavier weights break the brand's tonal restraint.
3. **Accent**: Violet (`#7c3aed`) is the sole interactive color. On hover → Translucent #281950 (75%) (`rgba(40, 25, 80, 0.75)`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. 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 (6px–56px). 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:
    - "Modern Compute Without the Complexity"
    - "Storage That Keeps Up"
    - "VMs That Do Everything You Need"
    - "Use the Tech You Love"
    - "TRUSTED BY TEAMS AT"
    - "Build Whatever You Can Think Up (and Give Your Users The Same Power)"
  ctas:
    - "Machines"
    - "Sign In"
    - "Get Started"
    - "Deploy your app"
    - "Check Em Out!"
    - "Learn More"
    - "Phoenix Framework"
    - "Docker"
  navigation:
    - "Deploy your app"
    - "Learn More"
    - "Phoenix Framework"
    - "SvelteKit"
    - "Ruby on Rails"
    - "Docker"
    - "Django"
    - "Laravel"
    - "NextJS"
    - "Enterprise Features"
  footer-links:
    - "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: 12
    avg-ratio: 4.19
    common-aspect: "~16:6 banner"
    sample-alts:
      - "Builder.io"
      - "Mercor"
      - "Context"
  product:
    count: 2
    avg-ratio: 0.99
    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">
  Machines
</button>
```
_Source pattern detected: padding `10px 12px` · radius `0px` · weight `500`_

**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** 20 · **cta** 1 · **auth** 1 · **pricing** 1 · **docs** 4 · **blog** 1 · **project** 1 · **social** 2 · **legal** 3 · **footer** 4 · **other** 22

**Primary actions (conversion path):**
- Account access — "Sign In" (login/signup) → `https://fly.io/app/sign-in`
- Primary call-to-action — "Get Started" (the conversion path) → `https://fly.io/app/sign-up`

**Signals:** 26/60 links carry a featured image · dominant link roles: content-card (23), navigation (20), footer-link (12).

## 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:*

- **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.
- **3 parasitic shadow(s) detected** — colored box-shadows (not near-black) found in allShadows. These likely originate from browser extensions or third-party injected widgets (e.g. Grammarly, chat overlays), not from the site's own design system. Discard them when building.

| Category | What's missing | Fallback strategy |
|----------|----------------|-------------------|
| **Dark mode** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants 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 |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 66 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 | 22 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | High | 7 images, hero present |

### Brand Gradient Palette

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

```css
/* Gradient 1 */
background: linear-gradient(to bottom right, #A02BE4, transparent, #4f46e5);

/* Gradient 2 */
background: linear-gradient(to bottom right, var(--tw-gradient-stops);

/* Gradient 3 */
background: linear-gradient(
      to right,
      hsla(217, 91%, 60%, var(--wave-opacity);

/* Gradient 4 */
background: linear-gradient(
    to bottom,
    #fff,
    hsla(0, 0%, 100%, 0.75);

/* Gradient 5 */
background: linear-gradient(
    to top,
    #fff,
    hsla(0, 0%, 100%, 0.75);

```

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 709 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**8 breakpoints** read from the live `@media` rules (not guessed):
`480px` · `640px` · `768px` · `1024px` · `1200px` · `1367px` · `1400px` · `1728px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×328 · `14.5px`×204 · `19px`×63 · `15.5px`×49 · `12px`×16 · `36px`×16 · `64px`×12 · `22px`×8

**Radius scale** (× = paint count): `9999px`×68 · `8px`×34 · `16px`×9 · `10px`×4 · `4px`×2 · `20px`×2

**Weights** (× = paint count): `325`×331 · `450`×245 · `500`×118 · `575`×12

**Layout gaps** (× = paint count): `32px`×29 · `8px`×14 · `normal 64px`×6 · `80px`×3 · `64px`×2 · `20px`×1 · `12px`×1 · `40px`×1

**Elevation (real shadows)**:
```css
rgba(67, 56, 202, 0.25) 0px 0px 0px 1px inset
rgba(91, 33, 182, 0.1) 0px 5px 5px -2px, rgba(91, 33, 182, 0.1) 0px 2px 4px -2px
rgba(32, 34, 55, 0.075) 0px 0px 0px 1px, rgba(32, 34, 55, 0.05) 0px 10px 15px -3px, rgba(32, 34, 55, 0.05) 0px 4px 6px -4px
rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px
```

### 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
header { font-size:0.90625rem }
header { font-weight:500 }
header { color:rgb(40 25 80 / var(--tw-text-opacity)) }
header { font-weight:450 }
h1 { font-family:Mackinac, ui-serif, Georgia, Cambria, "Times New Roman", Times, serif; font-weight:500 }
h1 { font-size:2rem }
h1 { color:rgb(40 25 80 / var(--tw-text-opacity)) }
@media (min-width: 480px) h1 { font-size:2.5rem }
@media (min-width: 640px) h1 { font-size:3rem }
@media (min-width: 768px) h1 { font-size:3.35rem }
@media (min-width: 1024px) h1 { font-size:3.75rem }
@media (min-width: 1200px) h1 { font-size:4rem }
```

> 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.
