/**
 * Build Launch - Login Page Course Strip
 * login-courses.css
 *
 * Infinite auto-scrolling marquee carousel.
 * Pure CSS animation - no JavaScript needed.
 * Pauses on hover. Fades out at both edges.
 *
 * To add a new course:
 *   1. Add a .trained-icon--xx colour rule below
 *   2. Copy a .trained-item block in login.html (inside BOTH .carousel-track divs)
