/* ==========================================================================================
   screens/board.css — 排行榜 (leaderboard, DESIGN §29): the 称号 boards of every finished
   match — 卫戍之星 / 坚若磐石 / 挥金如土 / 精英云集 and our own 卫戍之区 (most leaked) — one
   set per scope (单人局 / 多人局), aggregated server-side from the same results the 大厅
   shows (server/leaderboard.js, screens/board.js).
   The look is the 大厅's 最近战绩 (screens/hall.css): numbered section labels, bracketed
   panels, one row per holder. All sizes are rem (1rem = 100 design px at 1920×1080, css/theme.css).

   Source: original to this repository (the upstream project has no leaderboard).

   and 返回 (closeBoard) drops it again. One step above the screens, so it always wins. */
