    description: "Light product system built on #ffffff with #ffffff as the primary CTA accent. Type anchored in Plain at 52px / weight 400. Extracted automatically from https://pentagram.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
    narrative: |
      pentagram.com is built on a pure-white canvas (rgb(255,255,255)).
      The system uses rgb(255, 255, 255) as the singular interactive color.
      Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside Plain as the primary typeface.
      Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model.
      Motion is a first-class concern — 9 keyframe animations plus transition-driven interactions.

    ## 0. Design DNA
    
    **Density**: moderate  |  **Motion**: expressive  |  **Weight**: medium  |  **Aesthetic**: engineering-minimal
    
    | Dimension | Value | Signal |
    |---|---|---|
    | Canvas | neutral | `#ffffff` |
    | Type posture | sans-led (Plain) | "Our Future is the Ultimate Pro" |
    | Color assertion | single-accent | #ffffff |
    | Whitespace | moderate | section rhythm 48px |
    | Interaction | expressive | 9 keyframes, 19 transitions |
    | Radius language | 0px-architectural | from token scale |
    
    **Prism fingerprint**: `neutral-canvas · sans-display · single-accent · 0px-architectural · 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(255, 255, 255)` for primary CTAs ONLY. Never decorative.
    > - **Body type**: 19px (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.
    > - **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
    
    pentagram.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. 
    
    Typography is anchored in **Plain** with OpenType utility features (`"kern"`) for data-dense contexts. The weight scale rejects the standard 100/200/.../900 ladder in favor of custom values (max **400** in this system) — a deliberate signal that this design system is precisely tuned, not assembled from defaults. 
    
    Body text reads in Near-Black (`#1a1a1a`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Pure White** (`#ffffff`) provides interactive distinction without visual aggression. Shadow is absent by design — depth is conveyed through translucent borders and luminance steps rather than light simulation. 
    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: Pure White (`#ffffff`)
    - Primary typeface: Plain
    - Primary text: Near-Black (`#1a1a1a`)
    - Accent: Pure White (`#ffffff`)
    - Display: 19px weight 500
    - Custom fonts loaded: Plain

    > 1 size(s) detected outside the sampled hierarchy (13px). 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:
    
    - **case-sensitive forms** (`case`) — punctuation height adjusted for uppercase contexts
    
    **Clone instruction:** Enable these in your CSS:
    ```css
    body {
      font-feature-settings: "kern", "case", "smcp", "frac";
    }
    ```

    ## 4b. Component Behaviors (State Matrix)
    
    ### Interaction State Narrative
    
    - **Button**:
      - **hover:** text #1a1a1a → #767676, border changes
    
    *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*
    
    ```yaml
    component-behaviors:
      button:
        default:
          bg: "rgba(0, 0, 0, 0)"
          fg: "rgb(26, 26, 26)"
        hover:
          bg: "transparent"
          fg: "rgb(118, 118, 118)"
        focus:
          bg: "transparent"
          fg: "inherit"
      input:
        default:
          bg: "rgb(255, 255, 255)"
          fg: "rgb(26, 26, 26)"
      link:

          fg: "rgb(26, 26, 26)"
      card:
        default:
          bg: "rgba(0, 0, 0, 0)"
          fg: "rgb(255, 255, 255)"
      navLink:
        default:

          bg: "rgba(0, 0, 0, 0.07)"
          fg: "rgb(26, 26, 26)"
      footerLink:
        default:
          bg: "rgba(0, 0, 0, 0)"
          fg: "rgb(255, 255, 255)"
    ```
    
    **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand.
    
    
    ## 4c. Component Vocabulary (Closed System)
    
    *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.*
    
    ### Buttons
    - **2 shape(s)** in this system: `Light / Invert`, `Icon Button`
    - **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
    
    ## 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 | 4px |
    | sm | 8px |
    | md | 12px |
    | base | 18px |
    | lg | 24px |
    | xl | 32px |
    | 2xl | 48px |
    | 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 | 9999px | Cards, containers |
    | Lg | 10007px | Large rounded elements, pill segments |
    | Xl | 10015px | Category strips, featured containers |
    | Full | 9999px | Pills, avatars, circular elements |
    
    ### Shape Language
    
    | Component | Border Radius |
    |-----------|---------------|
    | Buttons | `0px` |
    | Inputs & Forms | `0px` |
    | Page Body | `0px` |
    | Navigation | `0px` |
    | Primary Input | `0px` |
    
    **Shape Personality**: Sharp & Angular — No rounding. Precise, editorial, enterprise feel.
    
    **Full Radius Spectrum**: 4px, 8px, full/pill (from `allBorderRadii` scan)
    
    
    ## 5b. Spacing Rhythm Names
    
    **Measured section padding**: bands use ~60px internal vertical padding (up to 60px) — **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** | `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:** left-aligned — 
    - **Viewport coverage:** 60px tall (not full-viewport)
    - **Heading:** "Pentagram" — 19px 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:** 20px
    - **Logo:** ✗ absent
    - **Nav links:** 5 primary items
    - **CTAs in nav:** 0 (no buttons — links only)
    - **Search:** ✓ search input visible in nav
    - **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed.
    
    ### Card Grid Pattern
    
    - **Card count:** 8 cards detected
    - **Columns (desktop):** 2-up grid
    - **Card dimensions:** 760×448px (aspect 1.69:1)
    - **Gap:** 0px between cards
    - **Content:** ✓ image
    - **Image position:** top
    - **Clone instruction:** Build a 2-column grid (desktop) with cards at ~1.69:1 aspect ratio. Each card has an image at the top.
    
    ### Testimonial Pattern
    
    - **Count:** 16 testimonial blocks
    - **Layout:** grid
    - **Avg quote length:** 179 chars (medium quote)
    - **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
    - **Clone instruction:** Build a grid of 16 testimonials.   
    
    ### Footer Pattern
    
    - **Columns:** 1
    - **Links:** 19 total
    - **Height:** 1543px
    - **Includes:** ✓ newsletter signup | ✓ social icons |  ✓ copyright
    - **Clone instruction:** Build a 1-column footer with ~19 links per column, newsletter signup, 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(0.4,0,0.2,1)` | Material Standard — Balanced |
    | `cubic-bezier(0.59,0.01,0.28,1)` | Ease Out — Decelerating |
    | `ease-in-out` | Ease In-Out — Symmetric |
    
    ### Duration Scale
    
    | Value | Tier | Typical Use |
    |-------|------|-------------|
    | `150ms` | Fast | Hover states, micro-interactions |
    | `250ms` | Normal | Panel open/close, navigation |
    | `300ms` | Normal | Panel open/close, navigation |
    | `400ms` | Slow | Hero animations, page transitions |
    | `500ms` | Slow | Hero animations, page transitions |
    | `600ms` | Slow | Hero animations, page transitions |
    
    ### Copy-Paste Transition Snippets
    
    **All Props**
    ```css
    transition: 0.3s cubic-bezier(0.4, 0, 0.2, 1);
    ```

    ### Keyframe Animation Catalog
    
    | Animation Name | Type | Animated Props | Use Hint |
    |----------------|------|----------------|----------|
    | `fadeIn` | Fade | opacity | Element entrance |
    | `slideInTop` | Fade + Move | opacity, transform | Panel / drawer enter |

    | `updownNumber2` | Slide | transform | UI transition |
    | `updownNumber3` | Slide | transform | UI transition |
    | `swiper-preloader-spin` | Rotate / Spin | transform | Loading indicator |
    
    ### Motion Fingerprint
    
    - **Speed Character**: Deliberate & Calm (median duration: `400ms`)
    - **Dominant Easing**: custom cubic-bezier curves
    - **Animation Library**: 9 unique animations (9 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 Near-Black (`#1a1a1a`) for text — not pure black, it's warmer and more readable
    - Use Plain as the primary typeface — it defines the brand personality
    - Keep font weights between 350-500 — the system uses a narrow weight range for subtle hierarchy
    - Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
    - Use Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color
    - Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
    - Include a search input directly in the nav — discoverability is a primary UX value here
    - Each card includes a top image — imagery is part of the card identity, not optional
    - Lay out testimonials in a grid (16+ items) — quantity signals scale and trust
    - Include a newsletter signup in the footer — email capture is part of the conversion funnel
    
    ### 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 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
    
    
    ## 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(255, 255, 255)` for primary CTAs and brand-mark signals only"
        why: "Single chromatic assertion device — overuse dilutes meaning"
        test: "querySelectorAll('[style*=\"rgb(255, 255, 255)\"]').length <= 3 per fold"
      - id: brand-depth-001
        type: dont
        rule: "Do NOT introduce drop shadows on cards or sections"
        why: "Containment is achieved via borders, not elevation — adding shadows breaks the depth contract"
        test: "getComputedStyle(card).boxShadow === 'none'"
    ```
    
    ## 9. Responsive Behavior
    
    ### Breakpoints
    | Name | Width | Key Changes |
    |------|-------|-------------|
    | Mobile | 470px | Single column, compact spacing |
    | Mobile Large | 570px | Expanded mobile layout |
    | Mobile Large | 666px | Expanded mobile layout |
    | Mobile Large | 755px | Expanded mobile layout |
    | Tablet | 799px | Multi-column grids begin |
    | Desktop | 1039px | Full feature layout |
    
    ### Token Diff — Desktop vs Mobile
    
    | Element | Property | Desktop | Mobile |
    |---------|----------|---------|--------|
    | heading | font-size | `19px` | `17px` |
    | body | font-size | `19px` | `17px` |
    | nav | display | `block` | `none` |
    | nav | height | `20px` | `auto` |
    | card | width | `455.984px` | `366px` |
    
    ### Collapsing Strategy
    - Headlines: 19px → 17px on mobile
    - Navigation: block → none on mobile
    - Cards: multi-column → stacked vertical on mobile
    - Footer: multi-column → stacked single column on mobile
    
    ### Touch Targets
    - Buttons: 0px 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: 2-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.*
    
    - **Glassmorphism** — 5 frosted/blur layer(s) (e.g. `blur(7.5px)`).
    
    > **Motion fingerprint**: glassmorphism (5 layers)
    
    ## 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://www.pentagram.com/pentagram_social.png (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: 2.33:1 (ultra-wide cinematic)
    - Rendered size: 1440×617px
    - Alt text: "Iso Cs 01"
    - *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): 55 (63%)
    - Portrait (<0.87): 21 (24%)
    - Square (0.87–1.15): 0 (0%)
    - Ultra-wide (>2.3): 12 (14%)
    
    **Media Format Mix:**
    - JPG: 37 (typically photographic content)
    - PNG: 7 (logos, transparent UI elements, mockups)
    - SVG: 2 (icons, illustrations, decorative geometry)
    
    **Average rendered image size:** 605×401px
    **Above-fold image count:** 16 / 88
    
    **Decorative Patterns Detected:**
    - 2 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
    - 16 background patterns (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:** Glassmorphism is a brand signature — use `backdrop-filter: blur(20px)` on overlapping surfaces.
    
    **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: Pure White (`#ffffff`)
    - Primary text: Near-Black (`#1a1a1a`)
    - Accent: Pure White (`#ffffff`)
    - Border: Slate Grey (`#767676`)
    - Font: Plain
    - Body: 19px weight 400
    
    ### Example Component Prompts
    - "Create a hero section on Pure White background (#ffffff). Headline at 19px Plain weight 500, line-height 1.32, color #1a1a1a."
    - "Create the primary CTA button: `#ffffff` background, `#1a1a1a` text, 9999px border-radius, 12px 24px padding, 500 weight, Plain font."
    - "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
    - "Build navigation: static on `#ffffff`. Plain 16px weight 400 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 Plain, weight range 350–500. Never exceed 500 — heavier weights break the brand's tonal restraint.
    3. **Accent**: Pure White (`#ffffff`) is the sole interactive color. On hover → Pure White (`#ffffff`). 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`, 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.*
    
    ```yaml
    copy:
      section-headings:
        - "See latest projects"
        - "8 latest Industrial/Product Design projects"
        - "1994 World Cup"
        - "Giorgia Lupi Interviewed on the Scratching the Surface Podcast"
      sub-headings:
        - "Our Future is the Ultimate Project"
        - "Hiut"
      navigation:
        - "Pentagram"
        - "Work"
        - "About"
        - "News"
        - "Contact"
        - "Archive"
      footer-links:
        - "Work"
        - "See all news"
        - "london@pentagram.com"
        - "Instagram"
        - "Privacy Policy"
    ```
    
    **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording.
    
    
    ## 15. Asset Inventory (Image Roles & Ratios)
    
    *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.*
    
    ```yaml
    assets:
      hero:
        count: 12
        avg-ratio: 2.33
        common-aspect: "~16:9 landscape"
        sample-alts:
          - "Iso Cs 01"
          - "Sm Mosaic Rooms Carousel"
          - "Nbm Landing Page Home"
    ```
    
    **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 `0px` · 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 · **blog** 1 · **project** 48 · **other** 7
    
    **Projects / case studies detected** (clustered by URL + featured image):
    
    *Work* — high confidence, 12 items:

    ## 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 (Plain, swiper-icons)** — 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.
    
    *✅ 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 | 230 CSS vars (semantic naming requires ≥20 for high) |
    | §3 Typography | High | 6 typography roles inferred |
    | §4 Components | Low | 2 component variants captured |
    | §7 Motion | High | Keyframes + transitions |
    | §8 Do's/Don'ts | High | 17 rules generated; design-decisions.json has evidence per rule |
    | §9 Responsive | High | 6 breakpoints detected |
    | §9b Photography | High | 88 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
    
    1 font file(s) captured (77KB total). When running `prism add`, fonts are saved to `extractions/pentagram.com/fonts/` and embedded as base64 in the output HTML.

    ## 11.2 Measured Reality (CDP Engine)
    
    Captured directly from Chrome's engine across **all 4125 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.
    
    ### Real Responsive Breakpoints
    **17 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
    `470px` · `570px` · `599px` · `600px` · `666px` · `755px` · `799px` · `800px` · `980px` · `1039px` · `1040px` · `1599px` · `1600px` · `1728px` … (+3 more)
    
    ### Measured Design Scale
    **Type scale by usage** (× = paint count): `19px`×2608 · `16px`×898 · `13px`×513 · `32px`×74 · `52px`×24 · `27px`×5

    ### 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:Helvetica Neue,Helvetica,Arial,sans-serif; color:#1a1a1a; font-size:17px }
    @media screen and (min-width: 800px) body { font-size:19px }
    body { font-family:var(--plain) }
    nav { font-family:var(--f-body-1-font-family); font-size:var(--f-body-1-font-size); font-weight:var(--f-body-1-font-weight) }
    main { transition:transform .5s cubic-bezier(.59,.01,.28,1) }
    h1 { font-weight:500 }
    h2 { font-weight:500 }
    button { font-family:inherit; font-size:100%; font-weight:inherit; color:inherit }
    button { color:var(--gray-550) }
    button { color:var(--gray-900) }
    a { color:var(--gray-900) }
    input { font-family:inherit; font-size:100%; font-weight:inherit; color:inherit }
    ```
    
    > 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.
