Since this is an output-only environment, we'll simulate the HTML structure and focus on the JavaScript logic. **Simulated HTML:** `html

``` **CSS (Conceptual):** `css .carousel { /* Container styles */ } .carousel-items { /* Styles for the item container */ } .carousel-item { /* Styles for individual items */ } .carousel-item.active { /* Styles for the active item */ } .carousel-prev, .carousel-next { /* Styles for navigation buttons */ } ``` >What will the simulated HTML structure allow us to focus on for this project?1d:T831,
