+/**
+ * IGNY8 Design System ESLint Plugin
+ * 
+ * This plugin enforces consistent component usage across the application.
+ * It prevents raw HTML elements and ensures all UI elements come from
+ * the central component library.
+ * 
+ * DOCUMENTATION:
+ * - Full component reference: docs/30-FRONTEND/COMPONENT-SYSTEM.md
+ * - Design guide: DESIGN-GUIDE.md (root)
+ * - Live demo: /ui-elements route
+ * 
+ * RULES:
+ * 1. no-raw-button - Use <Button> from components/ui/button/Button
+ * 2. no-raw-input - Use <InputField> from components/form/input/InputField
+ * 3. no-raw-select - Use <Select> from components/form/Select
+ * 4. no-raw-textarea - Use <TextArea> from components/form/input/TextArea
+ * 
+ * USAGE: Import in eslint.config.js and enable rules
