/* ============================================================
   67-serv-basketball-extra — "What Makes Our Club Different" and
   "Season Overview" sections on the Basketball Academy page.
   The "different" section mirrors the homepage's 06-journey
   scroll-pinned crossfade pattern (see css/sections/06-journey.css
   and js/sections/67-serv-different.js) since the client asked for
   the image to change as you scroll through each belief, not a
   static grid. Season overview reuses the generic .prog-grid/
   .prog-card pattern (66-serv-programs).
