All Implemented Interfaces:
InventoryTabInterface
public class InventoryTab extends Object implements InventoryTabInterface
UI tab that renders the player's inventory within the pause menu This tab shows a 4x4 grid of item slots. Each unique item present in the player's InventoryComponent occupies one "filled" slot, which renders a slot border and, if available, an item image. Remaining cells render as empty slots. The tab also provides a close hotspot (positioned with PixelPerfectPlacer) which unpauses the game and hides the pause screen when clicked.
