-- 其他城市按配置使用 `METAR / NOAA / Wunderground / 官方数据源`。
+- 其他城市按配置使用 `METAR / NOAA / 官方数据源`。
 - 城市展示名以主站返回值为准，例如 `aurora` 市场在插件中会显示为 `Denver`。

 - 当前版本仍是轻量产品，重点是“监控 + 基础判断 + 导流回站”，未接入支付链路。
 - 若你的 API 做了严格鉴权，请先在设置页填写 token 再使用。
-- 插件会按主站返回的结算源展示参考口径，例如 `Taipei / Shenzhen` 当前走 `Wunderground`，`Hong Kong / Lau Fau Shan` 走 `HKO`。
+- 插件走势图与主站保持一致：`Wunderground` 结算城市不再单独绘制结算参考线，统一显示机场 `METAR` / 官方观测点位。
 - 点击“打开网站查看更多”会回到主站继续查看完整分析。
 - 插件不会承载完整分析；完整结构判断、历史对账和更多信号仍以主站为准。
