/* 段落内联标签系统样式 */

/* 
 * ============================================
 * 文件职责说明
 * ============================================
 * 
 * 本文件包含法律法规详情页段落内联标签系统的所有样式：
 * 
 * 1. 内联标签容器 (.block-tags-inline)
 *    - 标签显示/隐藏逻辑
 *    - 位置和布局
 * 
 * 2. 单个标签项 (.inline-tag-item)
 *    - 标签色块 (.tag-color-bar)
 *    - 标签文本 (.inline-tag-name)
 *    - 聚焦状态 (.focused, .family-focused)
 * 
 * 3. 段落状态样式（⚠️ 统一管理处）
 *    - 聚焦段落 (.focused, .directly-focused)
 *    - 虚化段落 (.ghosted)
 *    - ⚠️ 注意：law-tags-sidebar.css 中的重复定义已移除
 * 
 * 4. 聚焦模式UI
 *    - 折叠占位符 (.collapsed-placeholder)
 *    - 顶部面包屑导航 (.law-tags-breadcrumb-top)
 * 
 * ⚠️ 避免重复定义：
 * - law-tags-sidebar.css：已移除段落状态样式
 * - law_tags_display.css：已废弃旧的 .tag-focused 样式
 * - law-tags-focus-panel.css：空文件，仅保留说明
 *
