narrative: |
  life360.com is built on a pure-white canvas (rgb(255,255,255)).
  The system uses rgb(239, 239, 239) as the singular interactive color.
  Crisp CTAs (4px radius) reinforce a precise, technical aesthetic alongside Times New Roman as the primary typeface.
  A restrained elevation system (1 distinct shadow) — shadows reserved for the few elements that must lift off the page.
  Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

# Design System — life360.com
> Extracted automatically by Prism from https://www.life360.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**: editorial-minimal

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | serif-led (Times New Roman) | "When they’re okay, you’re okay" |
| Color assertion | dual-accent | #efefef |
| Whitespace | moderate | section rhythm 48px |
| Interaction | subtle | 2 keyframes, 10 transitions |
| Radius language | 0px-architectural | from token scale |

**Prism fingerprint**: `neutral-canvas · serif-display · dual-accent · 0px-architectural · subtle-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(239, 239, 239)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (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.
>
> **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

life360.com uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. 

Headlines are set in **Times New Roman**, a serif display face (the dominant type signature, e.g. "When they’re okay, you’re okay." at 32px). Body text is set in **Hiragino Sans GB**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. 

Body text reads in Pure Black (`#000000`) (contrast ratio 21.0:1, well above WCAG AA). **Off-White** (`#efefef`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (1 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: Times New Roman
- Accent: Off-White (`#efefef`)
- Shadow system: 1 distinct elevation levels

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative


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

```yaml
component-behaviors:
  button:
    default:
      bg: "rgb(134, 82, 255)"
      fg: "rgb(255, 255, 255)"
      border: "1px solid rgb(255, 255, 255)"
  input:
    default:
      bg: "rgb(255, 255, 255)"
      fg: "rgb(0, 0, 0)"
      border: "2px inset rgb(118, 118, 118)"

```

**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
- **3 shape(s)** in this system: `Primary Brand`, `Icon Button`, `Subtle`
- **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 | 20px |
| 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 | 14px | Cards, containers |
| Lg | 20px | Large rounded elements, pill segments |
| Xl | 32px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `4px` |
| Inputs & Forms | `0px` |
| Page Body | `0px` |
| Navigation | `0px` |
| Primary Input | `0px` |

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

**Full Radius Spectrum**: 0px, 4px (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** | `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).

**4/8 structural patterns detected.**

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 1399px
- **Logo:** ✓ present
- **Nav links:** 1 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:** 3 cards detected
- **Columns (desktop):** 1-up grid
- **Card dimensions:** 1408×2744px (aspect 0.51:1)
- **Gap:** 0px between cards
- **Content:** ✓ image
- **Image position:** left
- **Clone instruction:** Build a 1-column grid (desktop) with cards at ~0.51:1 aspect ratio. Each card has an image at the left.

### Pricing Table Pattern

- **Tier count:** 3 pricing tiers
- **Layout:** vertical stacked
- **Columns (desktop):** 3-up
- **Feature list:** ✓ (median ~7 feature points per tier)
- **Clone instruction:** Build a 3-column vertical-stack pricing comparison.

### Footer Pattern

- **Columns:** 1
- **Links:** 32 total
- **Height:** 8533px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~32 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>`rgb(204, 204, 204) 0px 0px 2px 2px` | 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 |
|-------|---------------|
| `ease-out` | Ease Out — Decelerating |
| `ease` | CSS ease — Default |
| `linear` | Linear — No Easing |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `100ms` | Fast | Hover states, micro-interactions |
| `200ms` | Normal | Panel open/close, navigation |
| `300ms` | Normal | Panel open/close, navigation |
| `400ms` | Slow | Hero animations, page transitions |
| `700ms` | Cinematic | Splash, marketing reveals |

### Copy-Paste Transition Snippets

**Opacity**
```css
transition: opacity 0.7s, visibility 0s 0.7s;
```

**Color / Background**
```css
transition: color 0.2s ease-out;
```

**Background**
```css
transition: background-color 0.2s ease-out;
```

**Transform**
```css
transition: transform 0.1s linear, opacity 0.2s linear, visibility linear;
```

### Keyframe Animation Catalog

| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `delay-overflow` | Custom | overflow-x, overflow-y | UI transition |
| `osano-load-scale` | Fade + Move | transform, opacity | Focus / emphasis |

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 2 unique animations (2 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 the extracted shadow patterns for elevation — they are tuned to match the brand palette
- Use Off-White (`#efefef`) as the primary accent — it's the brand's signature interactive color
- Use small 4px radius for buttons — this design system uses subtle rounding, not pill shapes
- Style form inputs with a `2px inset rgb(118, 118, 118)` border — use border-based inputs, not floating labels or underline-only
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Each card includes a left image — imagery is part of the card identity, not optional

### Don't
- Don't invent new shadow values — use only the extracted shadow levels
- Don't introduce additional saturated accent colors — the palette is intentionally controlled
- Don't over-round buttons with pill or large radius — the system uses restrained, sharp-ish corners
- Don't remove the input border — the border is the primary affordance indicator for form fields
- 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(239, 239, 239)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(239, 239, 239)\"]').length <= 3 per fold"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 376px | Single column, compact spacing |
| Mobile | 480px | Single column, compact spacing |
| Mobile Large | 600px | Expanded mobile layout |
| Mobile Large | 750px | Expanded mobile layout |
| Tablet | 800px | Multi-column grids begin |
| Desktop | 1200px | Full feature layout |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | height | `1399.11px` | `479.781px` |
| button | width | `240px` | `273.594px` |
| card | width | `1424px` | `374px` |

### 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: 8px 12px 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):

*No major structural differences detected between desktop and mobile widgets. The same blueprints scale rather than collapse — verify by inspecting actual mobile render.*

## 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.life360.com/images/life360-og-image.jpg (1200×630px)
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Aspect Ratio Distribution:**
- Landscape (1.15–2.3): 2 (7%)
- Portrait (<0.87): 7 (26%)
- Square (0.87–1.15): 14 (52%)
- Ultra-wide (>2.3): 4 (15%)

**Media Format Mix:**
- JPG: 10 (typically photographic content)
- WebP: 9 (optimized photo/illustration hybrid)
- PNG: 4 (logos, transparent UI elements, mockups)
- SVG: 52 (icons, illustrations, decorative geometry)

**Average rendered image size:** 546×545px
**Above-fold image count:** 0 / 27

**Decorative Patterns Detected:**
- 48 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents

**Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content.

**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.

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 32px Times New Roman weight 700, line-height normal, color #000000."
- "Create the primary CTA button: `#efefef` background, `#ffffff` text, 4px border-radius, 8px 12px padding, 700 weight, Times New Roman font."
- "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 0px."
- "Build navigation: static on `#ffffff`. Times New Roman 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 Times New Roman, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: Off-White (`#efefef`) is the sole interactive color. On hover → Violet (`#8652ff`). Use CSS transitions, not opacity/brightness filters.
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 (4px–32px). 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.

    layout: block
    children: 1
```

**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:
    - "Location lowdown"
  sub-headings:
    - "Find lost or stolen stuff"
  ctas:
    - "Log In Log In/Sign Up"
    - "Tile Trackers"
    - "Family Safety"
  navigation:
    - "Homepage"
    - "Tile Small size, big features"
    - "Tile Pro Longest range"
    - "Tile Slim Fits anywhere"
    - "Tile Sticker Sticky to stay put"
    - "Sale Shop Limited Time Deals!"
    - "New Arrivals"
    - "Custom Branded Tiles"
    - "Explore Tile Trackers"
    - "Skip to main content"
  footer-links:
    - "Life360 Terms of Service"
    - "Your Privacy Choices"
```

**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: 7
    avg-ratio: 2.74
    common-aspect: "~16:6 banner"
    sample-alts:
      - "Life360 logo"
      - "Life360 logo"
      - "App Store Button"
  hero:
    count: 1
    avg-ratio: 2.22
    common-aspect: "~16:9 landscape"
    sample-alts:
      - "INTL Life360 Hero - 3369x1515"
  product:
    count: 8
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Core Tile 1"
      - "Core Tile Pro 1"
      - "Core Tile Slim 1"
```

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


## 16. Component HTML Templates

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

### Button (primary action)
```html
<button class="btn btn-primary">
  Action
</button>
```
_Source pattern detected: padding `8px 12px` · radius `4px` · weight `700`_

### 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** 18 · **cta** 4 · **blog** 1 · **social** 5 · **footer** 25 · **other** 1

**Primary actions (conversion path):**
- Primary call-to-action — "Trusted by millions to keep their families safe " (the conversion path) → `https://www.life360.com/deeplink?app=life360&action=open&url=https://www.life360.com/download?icid=messagebar_hp_eu`
- Primary call-to-action — "Get started" (the conversion path) → `https://www.life360.com/en-fr/plans-pricing`
- Primary call-to-action — "Try Life360 for free" (the conversion path) → `https://www.life360.com/en-fr/plans-pricing?icid=lead_ch3_eu`
- Primary call-to-action — "Get started" (the conversion path) → `https://www.life360.com/en-fr/sign-up?web_loc=plans&period=month&plan=free`

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

*Tile-Trackers* — medium confidence, 11 items:

| Title | Featured image | Link |
|---|---|---|
| Tile Small size, big features | `Core_Tile_1.webp?fm=webp` (ar 1) | https://www.life360.com/en-fr/tile-trackers/products/tile-mate?icid=nav_mate_eu |
| Tile Pro Longest range | `Core_Tile_Pro_1.webp?fm=webp` (ar 1) | https://www.life360.com/en-fr/tile-trackers/products/tile-pro?icid=nav_pro_eu |
| Tile Slim Fits anywhere | `Core_Tile_Slim_1.webp?fm=webp` (ar 1) | https://www.life360.com/en-fr/tile-trackers/products/tile-slim?icid=nav_slim_eu |

| Sale Shop Limited Time Deals! | `ImageAsset.png?fm=webp` (ar 1) | https://www.life360.com/en-fr/tile-trackers/products/deals?icid=nav_sale_eu |
| New Arrivals | — | https://www.life360.com/en-fr/tile-trackers/products/new-arrivals?icid=nav_new_eu |
| Explore Tile Trackers | — | https://www.life360.com/en-fr/tile-trackers?icid=nav_exploretrackers_eu |
| Track wallets, passports & more with the Til | — | https://www.life360.com/en-eu/tile-trackers/products/tile-slim?icid=messagebar_life360_slim26_eu |

**Signals:** 19/54 links carry a featured image · dominant link roles: footer-link (32), navigation (18), inline-link (3).

## Extraction Completeness: 75/100 (B)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 24 | 25 | 17 named colors |
| Typography | 20 | 20 | 8 roles defined |
| Components | 8 | 20 | 2 specs extracted |
| Motion & Interaction | 12 | 15 | Keyframes |
| CSS Custom Properties | 7 | 10 | 135 vars |
| Responsive Breakpoints | 5 | 5 | 6 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 (FontAwesome)** — 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 |
|----------|----------------|-------------------|
| **Hero imagery** | No dominant hero image detected above the fold | Use the canonical brand visual from §9b (OG image) for hero composition |
| **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 | 135 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 8 typography roles inferred |
| §4 Components | Low | 2 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 12 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | Medium | 27 images, hero not detected |

## 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

15 font file(s) captured (75KB total). When running `prism add`, fonts are saved to `extractions/life360.com/fonts/` and embedded as base64 in the output HTML.

**@font-face declarations to use:**
```css
@font-face {
  font-family: 'FontAwesome';
  /* src: url('/fonts/FontAwesome.woff2') format('woff'); */
  font-weight: normal;
  font-style: normal;
  font-display: swap;
}
```

### Keyframe Animations (Intercepted from CSS)

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

```
@keyframes fa-spin { ... }
```

<details><summary>Full keyframes CSS (1 animations)</summary>

```css
@-webkit-keyframes fa-spin{0%{-webkit-transform:rotate(0deg);transform:rotate(0deg)}100%{-webkit-transform:rotate(359deg);transform:rotate(359deg)}}
```
</details>

> **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 1160 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):
`376px` · `480px` · `600px` · `601px` · `750px` · `768px` · `800px` · `1200px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×1012 · `13.3333px`×95 · `13.28px`×17 · `18.72px`×16 · `32px`×6 · `26.6667px`×4 · `24px`×4 · `10.72px`×2

**Radius scale** (× = paint count): `4px`×9 · `50%`×1

**Weights** (× = paint count): `400`×1074 · `700`×82

**Elevation (real shadows)**:
```css
rgb(204, 204, 204) 0px 0px 2px 2px
```

### 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
button { border-radius:.25em; font-weight:bold; font-size:1em; background-color:var(--osano-button-background-color); color:var(--osano-button-foreground-color) }
a { color:var(--osano-link-color) }
```

> 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.
