-// http2Config is a package-internal version of net/http.HTTP2Config.

-// http.HTTP2Config was added in Go 1.24.
-// When running with a version of net/http that includes HTTP2Config,
-// we merge the configuration with the fields in Transport or Server
-// to produce an http2Config.
-//
-// Zero valued fields in http2Config are interpreted as in the
-// net/http.HTTPConfig documentation.
-//
-// Precedence order for reconciling configurations is:
-//
-// - Use the net/http.{Server,Transport}.HTTP2Config value, when non-zero.
-// - Otherwise use the http2.{Server.Transport} value.
-// - If the resulting value is zero or out of range, use a default.
