empty_frame(channel : UInt16, class_id : UInt16, body_size : UInt64) : Bytes

encode(class_id : UInt16, body_size : UInt64, props : Amqp::Properties) : Bytes

Builds the full header-frame payload (class-id .. property-list).

encode_properties(props : Amqp::Properties) : EncodedProperties

Encodes only the property flags and property-list tail. The body size is intentionally excluded so fixed-property publishers can reuse the tail.
