feedback7 UIBACK: a 设置 button left of 玩法说明 in the lobby's and the room's top bar (GitHub #238 by RushFTK) — ui/settings.js SettingsButton opens the same settings modal as the title screen and the match; no background-music option and no board-style option (the owner's decision of 2026-10-07: neither is official); test/ui/settings-entry.e2e.test.js; golden: unchanged (client only)
