/* ==========================================================================
   USCE Mentorship — the "See how it works" card deck.
   Shared by usce.html and index.html, so every selector is .el- scoped
   and nothing here touches the host page's own styles.

   Signature: each card is a boarding pass for the trip from paperwork to a
   US hospital. A route line across the deck shows where the slide sits on
   that journey, and each pass has a torn stub with its own flight data.
