Provides design token system and theming framework for consistent, customizable UI styling across all components. Covers complete token taxonomy (color, typography, spacing, shadows, borders, motion, z-index), theme switching (CSS custom properties, theme providers), RTL/i18n support (CSS logical properties), and accessibility (WCAG contrast, high contrast themes, reduced motion). This is the foundational styling layer referenced by ALL component skills. Use when theming components, implementing light/dark mode, creating brand styles, customizing visual design, ensuring design consistency, or supporting RTL languages.

Comprehensive design token system providing the foundational styling architecture for all component skills, enabling brand customization, theme switching, RTL support, and consistent visual design.
## Overview
Design tokens are the **single source of truth** for all visual design decisions. This skill provides:
1. **Complete Token Taxonomy**: 7 core categories (color, typography, spacing, borders, shadows, motion, z-index)
2. **Theme Switching**: Light/dark mode, high-contrast, custom brand themes
3. **RTL/i18n Support**: CSS logical properties for automatic right-to-left language support
4. **Multi-Platform Export**: CSS variables, SCSS, iOS Swift, Android XML, JavaScript
5. **Component Integration**: Skill chaining architecture for consistent styling across all components
**Critical Architectural Principle:**
```
Component Skills (Behavior + Structure) → Use tokens for ALL visual styling
Design Tokens (Styling Variables) → Define colors, spacing, typography
Theme Files (Token Overrides) → Light, dark, brand-specific values
```

## Quick Start
### Using Tokens in Components
**Step 1: Reference tokens in your component:**
```css
.button {
background-color: var(--button-bg-primary);
color: var(--button-text-primary);
padding-inline: var(--button-padding-inline);
padding-block: var(--button-padding-block);
border-radius: var(--button-border-radius);
transition: var(--transition-fast);
}
```
**Step 2: Themes automatically apply:**
```html
<!-- Light theme -->
<html data-theme="light">
<button class="button">Primary Button</button>
</html>
<!-- Dark theme (same component, different appearance) -->
<html data-theme="dark">
<button class="button">Primary Button</button>
</html>
```
**No code changes needed** - theme switching is automatic!
### Basic Theme Switching
```javascript
function setTheme(themeName) {
document.documentElement.setAttribute('data-theme', themeName);
localStorage.
