void AMyCharacter::BeginPlay()
{
    Super::BeginPlay();

    EquipmentComponent->InitializeEquipment(
        EquipmentInventoryComponent,   // Equipment inventory (holds equipped items)
        MainInventoryComponent,        // Main inventory (receives unequipped items)
        GetMesh()                      // Base character mesh (for body-part hiding)
    );
