/**
 * Build System for Cross-Provider Design Skills & Commands

 * Transforms feature-rich source files into provider-specific formats:
 * - Cursor: Downgraded (no frontmatter/args)
 * - Claude Code: Full featured (frontmatter + body)
 * - Gemini: Full featured (TOML + modular skills)
 * - Codex: Full featured (custom prompts + modular skills)
 *
 * Also builds Tailwind CSS for production deployment.
