narrative: |
  cohere.com is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(23, 23, 28) as a near-neutral accent (low saturation).
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside CohereText as the primary typeface.
  A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page.
  Motion is a first-class concern — 12 keyframe animations plus transition-driven interactions.

## 0. Design DNA

**Density**: sparse  |  **Motion**: expressive  |  **Weight**: heavy  |  **Aesthetic**: soft-rounded

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (Unica77 Cohere Web) | "Own your AI" |
| Color assertion | dual-accent | #17171c |
| Whitespace | sparse | section rhythm 60px |
| Interaction | expressive | 12 keyframes, 11 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(23, 23, 28)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 60px between major bands. Card padding: 24px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.

## 1. Visual Theme & Atmosphere

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

Headlines are set in **CohereText**, a sans-serif display face (the dominant type signature, e.g. "Own your AI" at 96px). A second display voice — **Unica77 Cohere Web** (sans) — appears in lower bands (e.g. "Safe. Flexible. Independent."), used for editorial accent. Body text is set in **Unica77 Cohere Web**. Negative letter-spacing at display sizes (-1.92px at 96px) compresses headlines into engineered blocks, dense and precise. 

Body text reads in Pure Black (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Near-Black** (`#17171c`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (2 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI. 
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. The site uses a variable font with CUTS + MOVE axes, enabling precise weight/width control across the type hierarchy. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: CohereText
- Accent: Near-Black (`#17171c`)
- Display: 96px weight 400, letter-spacing -1.92px
- Shadow system: 2 distinct elevation levels
- Custom fonts loaded: CohereText, CohereHeadline, CohereMono, CohereVariable, CohereColor, Unica77 Cohere Web

- **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

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

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

## 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 | 8px |
| sm | 12px |
| md | 16px |
| base | 20px |
| lg | 24px |
| xl | 40px |
| 2xl | 60px |
| 3xl | 72px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 4px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 12px | Cards, containers |
| Lg | 16px | Large rounded elements, pill segments |
| Xl | 50px | Category strips, featured containers |
| Full | 999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `999px` |
| Cards & Containers | `22px` |
| Inputs & Forms | `0px` |
| Navigation | `none` |
| Page Body | `0px` |
| Primary Input | `0px` |

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

**Full Radius Spectrum**: 0px, 2px, 4px, 6px, 8px, 12px, 16px, 50px (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

**Measured section padding**: bands use ~80px internal vertical padding (up to 152px) — **generous**. (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** | `40px` | Between major bands (color change, content shift) |
| **subsection** | `24px` | Within a section, between content groups |
| **card** | `16px` | Card padding, list-item spacing |
| **compact** | `12px` | Form fields, tight clusters, badge padding |
| **micro** | `8px` | 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:** 466px tall (not full-viewport)
- **Heading:** "Own your AI" — 96px center-aligned
- **Subheading:** "Your data. Your infrastructure. Cohere keeps it that way."
- **CTAs:** 1 (primary: "Request a demo")
- **Clone instruction:** Reproduce the **centered** 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:** fixed (stays visible during scroll)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 76px
- **Logo:** ✓ present
- **Nav links:** 52 primary items
- **CTAs in nav:** 1
- **Clone instruction:** Build a fixed logo left links left navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Card count:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1427×847px (aspect 1.69:1)
- **Gap:** 0px between cards
- **Content:** ✓ image
- **Image position:** top
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~1.69:1 aspect ratio. Each card has an image at the top.

### CTA Banner Pattern

- **Banner count:** 3
- **Position:** multiple
- **Visual treatment:** ✓ contrasting background
- **Primary CTA text:** "Go North"
- **Clone instruction:** Place multiple CTA banners across page sections. Use contrasting solid background.

### Footer Pattern

- **Columns:** 1
- **Links:** 45 total
- **Height:** 1334px
- **Includes:** ✓ newsletter signup | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~45 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 |
| Layered (Level 1) | <br>`rgba(172, 171, 171, 0.3) 0px -1px 10px 0px` | Cards, elevated surfaces |
| Layered (Level 2) | <br>`rgba(0, 0, 0, 0.3) 0px 32px 68px 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 |
| `ease-in-out` | Ease In-Out — Symmetric |
| `ease-in` | Ease In — Accelerating |

### Duration Scale

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

### Copy-Paste Transition Snippets

- **Animation Library**: 12 unique animations (12 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 Unica77 Cohere Web as the primary typeface — it defines the brand personality
- Keep font weights between 400-500 — the system uses a narrow weight range for subtle hierarchy
- Use negative letter-spacing (-1.92px) 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 (`#17171c`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Use 22px border-radius on cards — consistent with the grid card corners
- Keep navigation fixed to the top — the design uses a persistent navigation pattern
- Maintain nav height at 75.5938px — consistent vertical space for the navigation bar
- Use a single primary CTA in the hero — the design intentionally avoids choice paralysis
- Make the navigation fixed — it stays visible during scroll, signaling content depth
- Each card includes a top image — imagery is part of the card identity, not optional
- Repeat the primary CTA across 3 banner sections — conversion paths are layered, not single
- Include a newsletter signup in the footer — email capture is part of the conversion funnel

### Don't
- 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 use rectangular buttons for primary actions — the rounded pill shape is the brand standard
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence


## 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(23, 23, 28)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(23, 23, 28)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 460px | Single column, compact spacing |
| Mobile Large | 640px | Expanded mobile layout |
| Mobile Large | 767px | Expanded mobile layout |
| Tablet | 1023px | Multi-column grids begin |
| Desktop | 1100px | Full feature layout |
| Desktop | 1250px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `96px` | `60px` |
| heading | line-height | `96px` | `60px` |
| heading | letter-spacing | `-1.92px` | `-1.2px` |
| nav | padding | `16px 40px` | `20px 16px` |
| nav | height | `75.5938px` | `72px` |
| card | width | `420px` | `289px` |

### Collapsing Strategy
- Headlines: 96px → 60px on mobile
- Navigation: horizontal links → hamburger menu on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 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** — 52 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle).
- **Nav CTAs reduced** on mobile (1 → 0) — the design prioritizes content over conversion buttons at small sizes.


## 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(30px)`).
- **Clip-path shapes** — 8 non-rectangular cut(s).
- **CSS-variable animations** (2) — animated custom properties.

> **Motion fingerprint**: glassmorphism (1 layers), non-rectangular shapes (9)

## 9b. Visual Tone & Photography

**Tone:** Illustration-driven

The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand.

**Canonical Brand Image (OG):**
- https://cdn.sanity.io/images/rjtqmwfu/web3-prod/b966213f9f46bb9cec6ec5a3406e893530b8b292-1200x630.png?w=1200&h=630 (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: 1.61:1 (landscape (16:9-ish))
- Rendered size: 899×560px
- Alt text: "Background image"
- *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): 81 (92%)
- Portrait (<0.87): 1 (1%)
- Square (0.87–1.15): 3 (3%)
- Ultra-wide (>2.3): 3 (3%)

**Media Format Mix:**
- WebP: 3 (optimized photo/illustration hybrid)
- PNG: 5 (logos, transparent UI elements, mockups)
- SVG: 82 (icons, illustrations, decorative geometry)

**Average rendered image size:** 189×108px
**Above-fold image count:** 8 / 88

**Decorative Patterns Detected:**
- 18 multi-stop linear gradients (mesh-like, 3+ color stops) — the brand leans on rich color transitions for visual depth
- 2 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents
- **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:**
- Use vector illustration as the primary visual language — photos will read as off-brand.
- Maintain consistent illustration style (line weight, color palette) across the site.

## 10. Agent Prompt Guide

### Quick Reference
- Background: Pure White (`#ffffff`)
- Primary text: Pure Black (`#000000`)
- Accent: Near-Black (`#17171c`)
- Border: Charcoal (`#2e2e2e`)
- Font: Unica77 Cohere Web
- Body: 16px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 96px Unica77 Cohere Web weight 400, line-height 1, letter-spacing -1.92px, color #000000."
- "Create the primary CTA button: `#17171c` background, `#212121` text, 999px border-radius, 11px 21px padding, 500 weight, Unica77 Cohere Web font."
- "Design a card on `transparent` background. Border: none. Radius: 22px. Shadow: none. Padding: 0px."
- "Build navigation: fixed on `#ffffff`. Unica77 Cohere Web 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 Unica77 Cohere Web, weight range 400–500. Never exceed 500 — heavier weights break the brand's tonal restraint.
3. **Accent**: Near-Black (`#17171c`) is the sole interactive color. On hover → Coral (`#ff7759`). 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 `22px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (8px–40px). 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:
    - "Powering progress across industries"
    - "Ready to put AI to work?"
  sub-headings:
    - "Safe. Flexible. Independent."
    - "Your sovereign AI workplace"
    - "Developer resources"
    - "“With Cohere's latest highly secure enterprise LLMs, we aim to provide businesses with powerful and"
    - "Introducing North Mini Code: Cohere’s first model for developers"
    - "Cohere and Mila partner to advance Quebec French language and cultural context in AI"
  ctas:
    - "Show more"
    - "Necessary"
    - "Reject optional Save My Preferences"
    - "Reject optional"
    - "Save My Preferences"
  navigation:
    - "Products"
    - "CUSTOMIZATION"
    - "PRICING"
    - "MODELS OVERVIEW"
    - "Solutions"
    - "SECURITY"
    - "PRIVATE DEPLOYMENTS"
    - "Research"
    - "Resources"
    - "Learn more"
  footer-links:
    - "Request a demo"
    - "privacy policy"
    - "Products"
    - "North"
```

**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: 30
    avg-ratio: 1.89
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "Oracle Logo"
      - "Dell Technologies Logo"
      - "RBC Logo"
  product:
    count: 3
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
  thumbnail:
    count: 1
    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">
  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 `22px` · 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** 32 · **product** 11 · **pricing** 1 · **docs** 3 · **blog** 7 · **social** 5 · **footer** 1

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

*Blog* — medium confidence, 4 items:

| Title | Featured image | Link |
|---|---|---|

## 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 (CohereText, CohereHeadline, CohereMono)** — 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** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants unless explicitly requested |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | High | 65 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 11 typography roles inferred |
| §4 Components | Medium | 4 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 23 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 7 breakpoints detected |
| §9b Photography | High | 88 images, hero present |

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 3977 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**29 breakpoints** read from the live `@media` rules (not guessed) — 14 most relevant:
`336px` · `352px` · `410px` · `425px` · `440px` · `460px` · `480px` · `510px` · `530px` · `550px` · `576px` · `640px` · `660px` · `767px` … (+15 more)

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×3521 · `14px`×178 · `18px`×150 · `24px`×60 · `12px`×34 · `8px`×14 · `48px`×8 · `32px`×6

**Radius scale** (× = paint count): `4px`×57 · `22px`×31 · `9999px`×23 · `8px`×10 · `32px`×10 · `50%`×8 · `16px`×5 · `50px`×4

**Weights** (× = paint count): `400`×3941 · `700`×28 · `500`×4 · `600`×2

**Layout gaps** (× = paint count): `40px`×36 · `16px`×14 · `4px`×8 · `8px`×7 · `normal 24px`×7 · `16px normal`×7 · `normal 6px`×5 · `normal 40px`×4

**Elevation (real shadows)**:
```css
rgba(0, 0, 0, 0.3) 0px 32px 68px 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:#fafafa; font-family:Unica77 Cohere Web,Inter,Arial,ui-sans-serif,system-ui,sans-serif,Apple Color Emoji,Segoe UI Emoji,Segoe UI Symbol,Noto Color Emoji; font-size:16px; font-weight:400 }
body { background-color:#fff }
nav { background-color:rgb(255 255 255/var(--tw-bg-opacity,1)) }
h1 { font-family:CohereText,Space Grotesk,Inter,ui-sans-serif,system-ui,sans-serif,Apple Color Emoji,Segoe UI Emoji,Segoe UI Symbol,Noto Color Emoji }
h1 { font-size:3.75rem }
@media (min-width: 1024px) h1 { font-size:6rem }
h2 { font-family:Unica77 Cohere Web,Inter,Arial,ui-sans-serif,system-ui,sans-serif,Apple Color Emoji,Segoe UI Emoji,Segoe UI Symbol,Noto Color Emoji }
h2 { font-size:1.5rem }
h2 { color:rgb(23 23 28/var(--tw-text-opacity,1)) }
@media (min-width: 1024px) h2 { font-size:2rem }
button { font-family:inherit; font-size:100%; font-weight:inherit; color:inherit }
button { font-size:14px; font-family:inherit; font-weight:500; border-radius:2px }
```

> 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.
