/**
 * Per-frame byte production for streaming responses (SPEC.md §1.4).
 *
 * The reference codec encodes whole messages; the server streams frames as
 * they are produced. Rather than duplicating the codec's frame encoders
 * (and risking drift), each frame is encoded inside a minimal legal wrapper
 * message via the reference `encodeMessage`, and its length-prefixed bytes
 * are sliced back out by walking the frame headers. Wrapper stubs are a few
 * bytes; the reference codec remains the single source of wire bytes.
