 * css/screens/battle.css — 战斗页面补充样式（归属：jianghu 组）
 * 战斗主样式在 css/battle.css（battleView 组），这里只补页面层的东西：
 *   .bl-root       页面内容容器（#screen > .screen-content.full）
 *   .bl-has-bg     BattleLauncher 贴了 assets/bg/{bg}.webp 的战斗根元素
 *   .bl-title      顶部木条上的标题（战斗中与结算层都可见）
 *   .bl-empty      非法进入时的占位页
 * 不改 theme.css / screens.css / battle.css。
