### 入口导览与版本对照

页面以“入口路径 + 版本对照”为主线，帮您快速判断该走旧版还是 V2.0。

- **入口导览**：用四步流程说明从顶部指引到比分面板的完整路径。
- **版本对照表**：从入口位置、统计堆放方式、刷新间隔、适用人群四个维度对照旧版与 V2.0。
- **数据面板**：V2.0 把比赛拆成比分、关键事件、队伍数据、时间轴四块，每块各管什么一目了然。
- **场景分叉**：按“追比分”“赛后分头看”“按条件挑比赛”等场景，用分叉图指向更合适的版本。
- **刷新节奏**：实时层每 15 秒、赛后 10 分钟内出初版、之后按小时补充归档，时间线清楚展示。
- **上手准备**：列出设备、网络、检索方式与常用动作，让首次使用的用户少走弯路。
