/* =========================================================
   UNNAN UNITED LEAGUE — redesign B2 (2026.10)
   airy, near-white, quiet blue — but with UUL's own structure:
   horizontal copy + 16:9 video window, big thin English section titles,
   the client's cloud line as the heading mark, circle-arrow buttons,
   a flowing photo strip, a right-edge tab, a light footer
   ========================================================= */
