/**
 * TEA AI Tournament Studio - Public Banner Showcase
 * The signed-out-visible "home" page (js/router.js, path "/") that
 * rotates through recently published tournament banners as social proof
 * for people who haven't signed up / subscribed yet. Reuses the
 * .pub-banner* classes from publish.css for the actual banner content so
 * a showcase card looks identical to what an organizer sees in their own
 * Publish & Export preview.
