/**
 * KMOnlineSolutions - Video Playlist Carousel frontend.
 *
 * Large featured <video> player on top, horizontal thumbnail strip below.
 * Only poster images load on page load: the player uses preload="none" and
 * each card stores its file URL in data-src. The file is fetched only when
 * the user selects that thumbnail (or autoplay-next fires after "ended").
 *
 * Behaviour:
 *   - Click / Enter on a card loads it into the player and plays it.
 *   - Prev/next arrows scroll the strip by exactly one card (smooth).
 *   - Arrows auto-hide at the start / end of the list (and on mobile,
 *     where swipe takes over and arrows are CSS-hidden).
 *   - ArrowLeft / ArrowRight moves the selection when focus is inside
 *     the playlist (strip, cards, or player).
 *   - On "ended", the next video starts automatically (unless data-next=0
 *     or data-loop handling applies).
 *   - Per-video watch progress persists in localStorage and renders as a
 *     progress bar on each card.
