/* ═══ 2026-06-27 修复：active menu 下划线不跟主题 ═══
   根因 1：上面 --theme-accent → --theme-accent-current 改完，JS 未跑时 underline
            颜色 fallback 到 #07C160，但 JS 一跑就 OK，理论上不应持久绿。
   根因 2（真正的）：Butterfly 默认 underline 是 hover 触发 + 渐变色 brown，
            theme-system.css 之前的覆盖虽然 specificty 够，但用了 legacy --theme-accent
            （仅在 applyTheme 内设置），CSS 解析初期变量未定义 → fallback #07C160。
            如果 JS 异步加载慢或 theme 切换瞬态，underline 会"卡"在绿色。
   修复：
     a) 上面已把 --theme-accent 改 --theme-accent-current（更早 setProperty）
     b) 这里加 body 前缀的更高优先级兜底，覆盖所有可能的 active/select 类
     c) 用 ID 选择器升一级 specificity，确保压过 Butterfly 原生规则 */
