pub const HTTP_ZSTD_WINDOW_LOG_MAX: u32 = 23; // 23u32Expand description
RFC 9659 window ceiling for zstd under HTTP Content-Encoding: zstd: conformant senders require
a Window_Size of at most 8 MB (2^23) and decoders need only support up to that. This bounds
the decoder’s window allocation to 8 MB regardless of the (much larger) decompressed cap. It
governs HTTP content coding only; other transports (e.g. gRPC/OTLP, whose clients are not bound
by RFC 9659 and may legitimately use larger windows) are not clamped to it.
