   screens/briefing.css — INFO_CHECK briefing (js/screens/briefing.js) + the pre-game step header
   shared with the band draft (js/ui/matchChrome.js StepHeader). Research 06 §4.1 / §11.6.
   The bond rows, the legend and the banned operators (.brief-bonds / .brief-legend / .brief-banned) are
   js/ui/matchInfo.js MatchInfo — also shown by the band draft's 本局信息 dialog (css/screens/draft.css .minfo-dlg).
   2026-10-13 (the owner's request: the event's pre-game, video 6:29–7:51): one column of sections under grey header
   bars, 已就绪 and the big 准备就绪 in the bottom-right corner; the header with the step on the left and the countdown on
   the right. Original drawings only (CSS / inline SVG).
