Initial commit: Clean DSS implementation

Migrated from design-system-swarm with fresh git history. Old project history preserved in /home/overbits/apps/design-system-swarm Core components: - MCP Server (Python FastAPI with mcp 1.23.1) - Claude Plugin (agents, commands, skills, strategies, hooks, core) - DSS Backend (dss-mvp1 - token translation, Figma sync) - Admin UI (Node.js/React) - Server (Node.js/Express) - Storybook integration (dss-mvp1/.storybook) Self-contained configuration: - All paths relative or use DSS_BASE_PATH=/home/overbits/dss - PYTHONPATH configured for dss-mvp1 and dss-claude-plugin - .env file with all configuration - Claude plugin uses ${CLAUDE_PLUGIN_ROOT} for portability Migration completed: $(date) 🤖 Clean migration with full functionality preserved

+## Color Tokens
+
+All colors are defined as CSS custom properties with semantic naming.
+
+### Semantic Colors (Light Mode)

+### Semantic Colors (Dark Mode)
+
+Dark mode uses a `.dark` class on the root element:
+
+```css
+:root.dark {
+  --primary: #60a5fa;
+  --secondary: #818cf8;
+  --success: #34d399;
+  --warning: #fbbf24;

+  --background: #0f172a;
+  --card: #1e293b;
+  --card-foreground: #e2e8f0;
+  --border: #334155;
+  --input: #1f2937;
+  --ring: #60a5fa;
+}
+```
+
+### Color Usage Examples
+
+```css
+/* Buttons */
+.ds-btn[data-variant="primary"] {
+  background: var(--primary);
+  color: white;
+  border: 2px solid var(--primary);
+}
+
+.ds-btn[data-variant="destructive"] {
+  background: var(--destructive);
+  color: white;
+}
+
+.ds-btn[data-variant="ghost"] {
+  color: var(--foreground);
+  background: transparent;
+  border: 1px solid var(--border);
+}
+
+/* Toasts */
+.ds-toast[data-type="success"] {
+  background: linear-gradient(135deg,
+    color-mix(in oklch, var(--success) 5%, var(--card)) 0%,
+    var(--card) 100%);
+  border-left: 4px solid var(--success);
+}
+
+.ds-toast[data-type="error"] {
+  background: linear-gradient(135deg,
+    color-mix(in oklch, var(--destructive) 5%, var(--card)) 0%,
+    var(--card) 100%);
+  border-left: 4px solid var(--destructive);
+}
+
+/* Input states */
+.ds-input {
+  background: var(--input);
+  border: 2px solid var(--border);
+  color: var(--foreground);
+}
+
+.ds-input:focus {
+  border-color: var(--ring);
+  box-shadow: 0 0 0 3px color-mix(in oklch, var(--ring) 20%, transparent);
+}
+
+.ds-input[aria-invalid="true"] {
+  border-color: var(--destructive);
+}
+```
+
+### Color Accessibility
+
+All color combinations meet WCAG 2.1 Level AA requirements:

+|-------------|---|---|
+| Primary text on background | 14.2:1 | AAA |
+| Primary button (white text) | 8.4:1 | AAA |
+| Secondary button (white text) | 7.1:1 | AAA |
+| Muted text on background | 4.8:1 | AA |
+| Border on background | 5.2:1 | AA |

+  .ds-card {
+    padding: var(--space-4);  /* Reduce from 24px to 16px on mobile */
+  }
+}
+
+@media (max-width: 480px) {

+```
+
+---
+
+## Using Design Tokens
+
+### In CSS
+
+```css
+/* Using tokens in stylesheets */
+.my-component {
+  background: var(--primary);
+  color: var(--foreground);
+  padding: var(--space-4);
+  border-radius: var(--radius);
+  box-shadow: var(--shadow-md);
+  font-size: var(--text-base);
+  transition: all var(--duration-normal) var(--ease-default);
+}
+```
+
+### In CSS-in-JS
+
+```javascript
+// Using tokens in styled components
+const styles = `
+  background: var(--primary);
+  color: var(--foreground);
+  padding: var(--space-4);
+`;
+
+const component = document.createElement('div');
+component.style.cssText = styles;
+```
+
+### In JavaScript
+
+```javascript
+// Reading token values
+function getPrimaryColor() {
+  return getComputedStyle(document.documentElement)
+    .getPropertyValue('--primary')
+    .trim();
+}
+
+// Setting token values
+function setPrimaryColor(color) {
+  document.documentElement.style.setProperty('--primary', color);
+}
+
+// Within Web Components
+class MyComponent extends HTMLElement {
+  getCSSVariable(name) {
+    return getComputedStyle(this)
+      .getPropertyValue(name)
+      .trim();
+  }
+
+  setPrimaryColor(color) {
+    this.style.setProperty('--primary', color);
+  }
+}
+```
+
+### As SCSS Variables
+
+If using SCSS, you can reference tokens:
+
+```scss
+$primary: var(--primary);
+$secondary: var(--secondary);
+$space-4: var(--space-4);
+$duration-normal: var(--duration-normal);
+
+.my-button {
+  background: $primary;
+  padding: $space-4;
+  transition: all $duration-normal;
+}
+```
+
+---
+
+## Theme Customization
+
+### Changing Token Values
+
+#### Global Customization
+
+```css
+/* Override tokens globally */
+:root {
+  /* Custom colors */
+  --primary: #0066cc;
+  --secondary: #6366f1;
+  --success: #10b981;
+
+  /* Custom spacing */
+  --space-4: 1.25rem;  /* Increase default spacing */
+}
+```
+
+#### Dark Mode Customization
+
+```css
+/* Dark mode overrides */
+:root.dark {
+  --primary: #3b82f6;
+  --secondary: #818cf8;
+  --success: #34d399;
+
+  --foreground: #f1f5f9;
+  --background: #0f172a;
+  --card: #1e293b;
+  --card-foreground: #e2e8f0;
+}
+```
+
+#### Component-Specific Customization
+
+```css
+/* Override for specific component */
+.my-custom-button {
+  --primary: #ff6b6b;  /* Use custom primary for this button */
+  background: var(--primary);
+}
+```
+
+### Switching Between Themes
+
+```javascript
+// Add dark mode class
+function enableDarkMode() {
+  document.documentElement.classList.add('dark');
+  localStorage.setItem('theme', 'dark');
+}
+
+// Remove dark mode
+function disableDarkMode() {
+  document.documentElement.classList.remove('dark');
+  localStorage.setItem('theme', 'light');
+}
+
+// Toggle dark mode
+function toggleDarkMode() {
+  document.documentElement.classList.toggle('dark');
+}
+
+// Detect system preference
+function detectSystemTheme() {
+  if (window.matchMedia('(prefers-color-scheme: dark)').matches) {
+    enableDarkMode();
+  }
+}
+
+// Apply saved preference on load
+function loadSavedTheme() {
+  const saved = localStorage.getItem('theme');
+  if (saved === 'dark') {
+    enableDarkMode();
+  }
+}
+
+// Listen for system theme changes
+window.matchMedia('(prefers-color-scheme: dark)')
+  .addEventListener('change', (e) => {
+    if (e.matches) {
+      enableDarkMode();
+    } else {
+      disableDarkMode();
+    }
+  });
+```
+
+### Token Export for Other Platforms
+
+Design tokens can be exported for use in other design tools:
+
+```json
+{
+  "colors": {
+    "primary": "#3b82f6",
+    "secondary": "#6366f1",
+    "success": "#10b981"
+  },
+  "spacing": {
+    "4": "16px",
+    "6": "24px"
+  },
+  "typography": {
+    "base": "16px"
+  }
+}
+```
+
+---
+
+## Token Validation
+
+All components are validated to ensure they use design tokens instead of hardcoded values.
+
+### Validation Rules
+
+- ❌ **Hardcoded colors:** `background: #3b82f6;`
+- ✅ **Token colors:** `background: var(--primary);`
+- ❌ **Hardcoded spacing:** `padding: 16px;`
+- ✅ **Token spacing:** `padding: var(--space-4);`
+- ❌ **Hardcoded sizes:** `border-radius: 8px;`
+- ✅ **Token sizes:** `border-radius: var(--radius);`
+
+### Running Validation
+
+```bash
+npm run validate:tokens
+```
+
+---
+
+## Migration Guide
+
+### From v0.8.0 to v1.0.0
+
+**Before (Hardcoded values):**
+```css
+.button {
+  background: #3b82f6;
+  padding: 16px 24px;
+  border-radius: 8px;
+}
+```
+
+**After (Using tokens):**
+```css
+.button {
+  background: var(--primary);
+  padding: var(--space-3) var(--space-6);
+  border-radius: var(--radius);
+}
+```
+
+---
+
+## Best Practices
+
+1. **Always use tokens** - Never hardcode values
+2. **Use semantic names** - Pick colors by semantic meaning (primary, success) not appearance (blue, green)
+3. **Maintain contrast** - Ensure sufficient contrast for accessibility
+4. **Test themes** - Always test in both light and dark modes
+5. **Document changes** - Update this guide when adding tokens
+6. **Version tokens** - Keep tokens in sync with component versions
