+# EMCN Component Guidelines
+
+## When to Use CVA vs Direct Styles
+
+**Use CVA (class-variance-authority) when:**
+- 2+ visual variants (primary, secondary, outline)
+- Multiple sizes or state variations
+- Example: Button with variants
+
+**Use direct className when:**
+- Single consistent style
+- No variations needed
+- Example: Label with one style
+
+## Patterns
+
+**With CVA:**
+```tsx
+const buttonVariants = cva('base-classes', {
+  variants: { 
+    variant: { default: '...', primary: '...' },
+    size: { sm: '...', md: '...' }
+  }
+})
+export { Button, buttonVariants }
+```
+
+**Without CVA:**
+```tsx
+function Label({ className, ...props }) {
+  return <Primitive className={cn('single-style-classes', className)} {...props} />
+}
+```
+
+## Rules
+- Use Radix UI primitives for accessibility
+- Export component and variants (if using CVA)
+- TSDoc with usage examples
+- Consistent tokens: `font-medium`, `text-[12px]`, `rounded-[4px]`
+- Always use `transition-colors` for hover states
