 * universe-carousel.css — P6.4 live universe carousel

 * A horizontal strip of ticker cards above the scanner panels. Each

 * the right. Styled with Bootstrap/Phoenix CSS variables so it tracks
 * the active theme (light/dark). Behavior lives in
 * universe-carousel.js; this file is presentation only.
