```
public class MerchandiseLineItem
extends java.lang.Object
```
Mutable line item wrapping a Merchandise catalog entry. Adds JavaFX properties for selection state, optional description, quantity, and effective price. The price defaults to the catalog's defaultCost but can be overridden by the user for items that have no default cost. For per-unit items the price is recomputed from quantity × defaultCost whenever the spinner value changes.
