To allow users to swipe left or right in the card detail screen to navigate through the search results or binder cards:

1. **Active Session Manager (`CardSessionManager`):**
   * Implement a singleton `@Singleton class CardSessionManager` that holds the current list of card IDs (e.g. `val activeCardIds =

MutableStateFlow<List>(emptyList())). * Add a function setCardIds(ids: List)` to update this list.

2. **Populate Active Session:**
   * When tapping a card in `CardSearchScreen` or `BinderDetailScreen`, populate the active card session using `CardSessionManager.setCardIds(listOfCardIds)` with

the currently displayed results.
* Navigate to Screen.CardDetail as normal, passing the clicked card ID.

3. **HorizontalPager Integration:**
   * Update `CardDetailScreen.kt` and `CardDetailViewModel.kt` to retrieve the active card ID list.
   * Locate the index of the clicked card ID within the list to serve as the initial page.
   * Use Jetpack Compose’s `HorizontalPager` with `rememberPagerState`:
     ```kotlin
     val pagerState = rememberPagerState(
         initialPage = initialIndex,
         pageCount = { activeCardIds.size }
     )
     ```
   * Wrap the detail contents inside a `HorizontalPager(state = pagerState)`.
   * Render the layout for the active card dynamically on each page by passing the corresponding card ID to a page sub-component (e.g. `CardDetailContent(cardId =

activeCardIds[page])`).
