### Business Rules

1. **Nested Subcategories**
   - Subcategories can have unlimited nesting levels
   - A subcategory with items (`hasItems: true`) cannot have child subcategories
   - Creating a subcategory under a parent with items will fail

2. **Item Management**
   - When first item is created in a subcategory, `hasItems` is set to true
   - When last item is deleted, `hasItems` is set to false
   - Items belong to the deepest subcategory in the hierarchy

3. **Comments**
   - Stars field is optional (1-5 rating)
   - createdAt is ISO 8601 timestamp
   - author is optional (can be anonymous)

4. **URL Structure for Marketplace**
   - Items: `/{categoryId}/{subcategoryId}/.../{itemId}`
   - Example: `/electronics/smartphones/iphone-15`
   - Example nested: `/electronics/smartphones/apple/iphone-15`
