+"""抖音 aweme detail 接口的风控参数回归测试。
+
+回归背景：上游 detail 接口的 Argus 风控要求 ``uifid`` / ``verifyFp`` / ``fp``
+三个参数，缺一时直接 403，响应体为
+``Blocked by ArgusSecurityPlugin Uifid Not Found``（补上 uifid 但 verifyFp 不对时
+换成 ``... Signature Not Found``）。原先只传 aweme_id，于是详情全线失败，
+连带媒体也拿不到。
+
+这里不发起任何网络请求，只锁定这三个参数确实被带上、且取值来自浏览器 cookie。
