description: "Light product system built on #ffffff with #004488 as the primary CTA accent. Type anchored in OpenSansCond at 35px / weight 700. Extracted automatically from https://onetonline.org/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)."
narrative: |
  onetonline.org is built on a pure-white canvas (rgb(255, 255, 255)).
  The system uses rgb(0, 68, 136) as the accent for primary actions and brand signals.
  Sharp 0px corners on CTAs — architectural restraint, engineering precision alongside OpenSansCond 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 — 12 keyframe animations plus transition-driven interactions.

# Design System — onetonline.org
> Extracted automatically by Prism from https://www.onetonline.org/explore/interests/
> Date: 2026-06-11
> Viewport: Desktop 1440x900 + Mobile 390x844

## 0. Design DNA

**Density**: moderate  |  **Motion**: expressive  |  **Weight**: heavy  |  **Aesthetic**: sharp-architectural

| Dimension | Value | Signal |
|---|---|---|
| Canvas | neutral | `#ffffff` |
| Type posture | sans-led (OpenSans) | "Browse by Career Interest Type" |
| Color assertion | dual-accent | #004488 |
| Whitespace | moderate | section rhythm 48px |
| Interaction | expressive | 12 keyframes, 7 transitions |
| Radius language | 0px-architectural | from token scale |

**Prism fingerprint**: `neutral-canvas · sans-display · dual-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(0, 68, 136)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 14px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 21px.
> - **Default radius**: 7px 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

**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.

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

Headlines are set in **OpenSansCond**, a sans-serif display face (the dominant type signature, e.g. "Browse by Career Interest Types" at 35px). Body text is set in **OpenSans**. Headlines use weight 700 for confident, assertive presence — the brand wants to be heard. 

Body text reads in Near-Black (`#212529`) — softened from pure black, a small but deliberate detail that lowers reading friction. **#004488** (`#004488`) 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. Shadow is absent by design — depth is conveyed through borders, spacing, and color differentiation rather than light simulation. 
Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Pure White (`#ffffff`)
- Primary typeface: OpenSans
- Primary text: Near-Black (`#212529`)
- Accent: #004488 (`#004488`)
- Custom fonts loaded: OpenSans, OpenSansCond

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **Input**:
  - **focus:** shadow added, border changes
- **Link**:
  - **hover:** text #0d6efd → #0a58ca, 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(33, 37, 41)"
  input:
    default:
      bg: "rgb(255, 255, 255)"
      fg: "rgb(33, 37, 41)"
      border: "1px solid rgb(222, 226, 230)"
    focus:
      bg: "transparent"
      fg: "inherit"
      border: "1px solid rgb(220, 225, 231)"
      shadow: "rgba(13, 110, 253, 0.008) 0px 0px 0px 0.0855841px"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(13, 110, 253)"
    hover:
      bg: "transparent"
      fg: "rgb(10, 88, 202)"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(33, 37, 41)"
```

**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: `Ghost`, `Primary Brand`
- **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

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

### Alerts
- **1 shape(s)** in this system: `Alert Banner`
- **DO NOT introduce new alerts 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 | 7px |
| md | 11px |
| base | 14px |
| lg | 21px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 5.25px | Tiny corners (badges, micro elements) |
| Sm | 7px | 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 | `0px` |
| Inputs & Forms | `0px` |
| Navigation | `none` |
| Alerts | `5.25px` |
| Page Body | `0px` |
| Primary Input | `0px` |

**Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill.

**Full Radius Spectrum**: 0px, 5.25px, 6px, 7px (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** | `21px` | Within a section, between content groups |
| **card** | `11px` | Card padding, list-item spacing |
| **compact** | `7px` | 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.**

### Hero Pattern

- **Composition:** left-aligned — 
- **Viewport coverage:** 567px tall (not full-viewport)
- **Heading:** "Browse by Career Interest Types" — 35px left-aligned
- **Subheading:** "Career interest types are broad types of work you enjoy. Select an interest to discover occupations that support the interest type."
- **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:** 49px
- **Logo:** ✓ present
- **Nav links:** 7 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:** 3 cards detected
- **Columns (desktop):** 4-up grid
- **Card dimensions:** 367×88px (aspect 4.17:1)
- **Gap:** 0px between cards
- **Content:** ✗ no image + icon
- **Clone instruction:** Build a 4-column grid (desktop) with cards at ~4.17:1 aspect ratio. Text/icon-only cards (no photography).

### Footer Pattern

- **Columns:** 3
- **Links:** 17 total
- **Height:** 102px
- **Includes:** ✗ no newsletter | ✓ social icons |  
- **Clone instruction:** Build a 3-column footer with ~6 links per column, social media links.

## 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 |
|-------|---------------|
| `ease` | CSS ease — Default |
| `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 |

### Copy-Paste Transition Snippets

**Border**
```css
transition: border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out;
```

**Color / Background**
```css
transition: color 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in...;
```

**Shadow**
```css
transition: box-shadow 0.15s ease-in-out;
```

**Color / Background**
```css
transition: color 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out;
```

### Keyframe Animation Catalog

| Animation Name | Type | Animated Props | Use Hint |
|----------------|------|----------------|----------|
| `fa-beat` | Scale | transform | UI transition |
| `fa-bounce` | Scale | transform | Playful feedback |
| `fa-fade` | Fade | opacity | UI transition |
| `fa-beat-fade` | Fade + Move | opacity, transform | UI transition |
| `fa-flip` | Rotate / Spin | transform | UI transition |
| `fa-shake` | Rotate / Spin | transform | Error feedback |
| `fa-spin` | Rotate / Spin | transform | Loading indicator |
| `progress-bar-stripes` | Custom | background-position-x | UI transition |
| `spinner-border` | Rotate / Spin | transform | Loading indicator |
| `spinner-grow` | Fade + Move | transform, opacity | Loading indicator |
| `placeholder-glow` | Fade | opacity | Attention / status |
| `placeholder-wave` | Custom | -webkit-mask-position-x, -webkit-mask-position-y | UI transition |

### Motion Fingerprint

- **Speed Character**: Deliberate & Calm (median duration: `300ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **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 Near-Black (`#212529`) for text — not pure black, it's warmer and more readable
- Use OpenSans as the primary typeface — it defines the brand personality
- Use #004488 (`#004488`) as the primary accent — it's the brand's signature interactive color
- Style form inputs with a `1px solid rgb(222, 226, 230)` border — use border-based inputs, not floating labels or underline-only
- Maintain nav height at 49px — consistent vertical space for the navigation bar
- Respect the 4px–32px spacing range — the design uses a wide scale for visual breathing room
- Each card uses an icon (not photo) — the visual language is illustrative, not photographic
- Use a 4-column grid on desktop — density matters for this content type

### 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 introduce additional saturated accent colors — the palette is intentionally controlled
- Don't remove the input border — the border is the primary affordance indicator for form fields
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- 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

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 576px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 992px | Multi-column grids begin |
| Desktop | 1200px | Full feature layout |
| Large Desktop | 1400px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| heading | font-size | `35px` | `25.1px` |
| heading | line-height | `42px` | `30.12px` |
| nav | height | `49px` | `49.25px` |

### Collapsing Strategy
- Headlines: 35px → 25.1px 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: 3.5px 14px 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** — 7 links visible on desktop, 0 on mobile (the rest hide behind a menu toggle).
- **Card grid: 4-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.
- **Footer columns collapse:** 3 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.*

- **CSS-variable animations** (3) — animated custom properties.

> **Motion fingerprint**: standard CSS transitions only

## 9b. Visual Tone & Photography

**Tone:** Mixed photography + illustration

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

**Canonical Brand Image (OG):**
- https://www.onetonline.org/shared/image/promo/online.jpg
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Hero Image (above-fold dominant visual):**
- Aspect: 5:1 (ultra-wide cinematic)
- Rendered size: 400×80px
- Alt text: "O*NET OnLine"
- *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): 0 (0%)
- Portrait (<0.87): 0 (0%)
- Square (0.87–1.15): 0 (0%)
- Ultra-wide (>2.3): 1 (100%)

**Media Format Mix:**
- SVG: 1 (icons, illustrations, decorative geometry)

**Average rendered image size:** 400×80px
**Above-fold image count:** 1 / 1

**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: Near-Black (`#212529`)
- Accent: #004488 (`#004488`)
- Border: Whitesmoke (`#dee2e6`)
- Font: OpenSans
- Body: 14px weight 400

### Example Component Prompts
- "Create a hero section on Pure White background (#ffffff). Headline at 35px OpenSans weight 700, line-height 1.2, color #212529."
- "Create the primary CTA button: `#004488` background, `#ffffff` text, 0px 5.25px 5.25px 0px border-radius, 5.25px 10.5px padding, 700 weight, OpenSans font."
- "Build navigation: relative on `#ffffff`. OpenSans 14px 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 OpenSans, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint.
3. **Accent**: #004488 (`#004488`) is the sole interactive color. On hover → #0d6efd (`#0d6efd`). Use CSS transitions, not opacity/brightness filters.
4. **Focus**: Render focus rings in Translucent #0d6efd (25%) (`rgba(13, 110, 253, 0.25)`) — never hide focus outlines. The ring color is distinct from the accent to avoid ambiguity.
5. **Shape**: CTAs at `0px 5.25px 5.25px 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.

## 11. CSS Design Tokens Raw Export

*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

```css
/* Colors */
:root {
  --ca-on-primary: #ffffff;
  --ca-surface-2: #f8f9fa;
  --ca-ink: #212529;
  --ca-ink-subtle: #2b2f32;
  --ca-primary: #004488;
  --ca-primary-focus: #0d6efd;
  --ca-hairline: #dee2e6;
  --ca-semantic-error: #58151c;
  --ca-semantic-success: #198754;
  --ca-semantic-warning: #fff3cd;
  --ca-semantic-info: #055160;
}

/* Typography */
:root {
  --ca-font-primary: "OpenSansCond", system-ui, sans-serif;
  --ca-text-display: 35px;
  --ca-text-body: 14px;
  --ca-text-button: 28px;
}

/* Spacing & Radius */
:root {
  --ca-space-xxs: 2px;
  --ca-space-xs: 4px;
  --ca-space-sm: 7px;
  --ca-space-md: 11px;
  --ca-space-base: 14px;
  --ca-space-lg: 21px;
  --ca-space-xl: 32px;
  --ca-space-2xl: 48px;
  --ca-space-3xl: 64px;
  --ca-radius-none: 0px;
  --ca-radius-xs: 5.25px;
  --ca-radius-sm: 7px;
  --ca-radius-md: 14px;
  --ca-radius-lg: 20px;
  --ca-radius-xl: 32px;
  --ca-radius-full: 9999px;
}
```


## 13. Page Structure Skeleton

*The actual layout the source site uses. Reproduce these sections in order to match the site structure.*

```yaml
page-skeleton:
  - section: feature-section
    tag: div
    classes: ["grid-parent"]
    height: 931px
    width: 1100px
    layout: block
    children: 2
  - section: feature-section
    tag: div
    classes: ["container-fluid"]
    height: 931px
    width: 1100px
    layout: block
    children: 1
    padding: "0px 10.5px"
```

**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:
  ctas:
    - "Go"
    - "Yes, it was helpful"
  navigation:
    - "Share"
    - "Help"
    - "Find Occupations"
    - "Advanced Searches"
    - "O*NET Data"
    - "Crosswalks"
    - "Sites"
```

**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:
```

**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">
  Go
</button>
```
_Source pattern detected: padding `5.25px 10.5px` · radius `0px 5.25px 5.25px 0px` · weight `400`_

**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** 7 · **docs** 4 · **footer** 4 · **other** 17

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

## 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 (OpenSans, OpenSansCond)** — 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 | 178 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | Medium | 3 typography roles inferred |
| §4 Components | Medium | 4 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 15 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 5 breakpoints detected |
| §9b Photography | High | 1 images, hero present |

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 306 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**5 breakpoints** read from the live `@media` rules (not guessed):
`576px` · `768px` · `992px` · `1200px` · `1400px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `14px`×161 · `12.25px`×73 · `28px`×62 · `19.6px`×6 · `35px`×3

**Radius scale** (× = paint count): `5.25px`×4 · `7px`×2

**Weights** (× = paint count): `400`×300 · `700`×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:var(--bs-body-font-family); font-size:var(--bs-body-font-size); font-weight:var(--bs-body-font-weight); color:var(--bs-body-color); background-color:var(--bs-body-bg) }
body { font-family:OpenSans, Verdana, sans-serif }
nav { background-color:rgba(var(--bs-light-rgb),var(--bs-bg-opacity))!important }
nav { background:linear-gradient(#fff, #ddd); border-radius:.5rem; background-color:initial }
h1 { font-size:calc(1.375rem + 1.5vw) }
@media (min-width: 1200px) h1 { font-size:2.5rem }
button { font-weight:400; color:var(--bs-dropdown-link-color); background-color:transparent; border-radius:var(--bs-dropdown-item-border-radius,0) }
a { color:rgba(var(--bs-link-color-rgb),var(--bs-link-opacity,1)) }
input { font-size:1rem; font-weight:400; color:var(--bs-body-color); background-color:var(--bs-body-bg); border-radius:var(--bs-border-radius); transition:border-color .15s ease-in-out,box-shadow .15s ease-in-out }
button { font-family:var(--bs-btn-font-family); font-size:var(--bs-btn-font-size); font-weight:var(--bs-btn-font-weight); color:var(--bs-btn-color); border-radius:var(--bs-btn-border-radius); background-color:var(--bs-btn-bg); transition:color .15s ease-in-out,background-color .15s ease-in-out,border-color .15s ease-in-out,box-shadow .15s ease-in-out }
```

> 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.
