As a user of the demo application, I want to be able to collapse and expand sections in the interface to reduce visual clutter as more showcases are added.
Acceptance Criteria

When an implementation section is collapsed, it hides its content and only the title is displayed.
Add a visual cue (such as an arrow icon) next to each showcase section title to signify collapsibility.
