Background
The carousel will need a number of refinements. We are collecting these in this ticket
Requirements
We need to refine the UI of the Carousel component to include the following:
- Image thumbnails are the correct height. Per https://phabricator.wikimedia.org/T402222#11100172: height: 175px, width: 100px < size < 33%
- Horizontal and vertical pano images are cropped to reasonable limits so they don't become tiny or huge
- Carousel images showcase good interaction design patterns. Per https://phabricator.wikimedia.org/T402222#11100198: 1px border with border-color: interactive--hover
@JScherer-WMF feel free to elaborate further or include any mockups.
