// Hysteria stream transport. Per Xray docs (transports/hysteria.html), the

// the essentials — version, auth, udpIdleTimeout, and masquerade. The
// extended bandwidth/window/udphop knobs that earlier hysteria builds
// exposed are not part of this transport's wire shape.

// Inbound masquerade — Xray's hysteria inbound can disguise itself as an
// HTTP/3 server. `type` is the empty string by default (serves the default
// 404 page), and per-type config keys are only honored when their type is
// active.
