/* ============================================================================
 * 爆款复刻（Reverse Video）· 前端样式（2026-10-28）
 * ----------------------------------------------------------------------------
 * 定位：这是「分析工具」，不是「创作工具」——所以视觉上要克制：
 *   · 主色沿用视频板块的橙（#f95901），但只用在主按钮和阶段进度上
 *   · 内容区用纸白 + 细线卡片，分镜用大序号排布，像一份拆解报告
 *   · 不做花哨背景 —— 用户看的是信息密度，不是装饰
 * 🔴 类名前缀 `rv-`，作用域限定 #sub-revideo。
