Digital Production Factory 276ed71f31 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

/**
* Variant Generator - Auto-generates CSS for all component variants
*
* This system generates CSS for all component state combinations using:
* 1. Component definitions metadata (variant combinations, tokens, states)
* 2. CSS mixin system for DRY code generation
* 3. Token validation to ensure all references are valid
* 4. Dark mode support with color overrides
*
* Generated variants: 123 total combinations across 9 components
* Expected output: /admin-ui/css/variants.css
*
* Usage:
* const generator = new VariantGenerator();
* const css = generator.generateAllVariants();
* generator.exportCSS(css, 'admin-ui/css/variants.css');
