  * @param modifier                Modifier applied to the composable root.
  * @param displayOptions          Controls checkbox and secondary-info visibility.
  * @param callbacks               Hooks for filtering and reacting to selection changes.
- * @param storyFragmentManager    [FragmentManager] used to show story-related dialogs.

  * @param onListCommitted         Called after each list commit with the committed item count.
- * @param itemDecorations         [RecyclerView.ItemDecoration]s added to the internal list.
- * @param contentBottomPadding    Extra bottom padding so last items scroll above overlaid UI.
