+# 现状：http2 + ha=2 大约 60~75% 可用。剩下 25% 失败的原因是
+#       到 Cloudflare 美西边缘（sjc/lax）的国际链路丢包。
+#
+# 单协议单通道扛不住，那就试三套：
+#   A) http2 + ha=2            现状
+#   B) http2 + ha=4            TCP 下多连接不像 UDP 那样互相挤
+#   C) http2 ha=1 + quic ha=1  两个进程、两种协议同时挂着
+#                              —— Cloudflare 会在所有连接间分发请求，
