3x-ui: gRPC transport

gRPC isn't the primary channel — it's a hidden fallback of a different "kind" for when the main TCP-Reality starts getting throttled. VLESS on the inside, Reality masquerade on the outside, transport is HTTP/2 multiplexing. Below is the 3x-ui build via the connection form, plus an honest note that gRPC is already deprecated in Xray 26. Enter your data in the builder above.

Honestly: I don't run it as a primary transport, and I don't advise you to either. But gRPC has a role — a hidden fallback of a different profile. Traffic goes as ordinary gRPC calls over HTTP/2 (multiplexing — several streams in one connection), VLESS on the inside, and on the outside the same Reality masquerade as someone else's TLS 1.3.
